Carteck Centre Ribbed (3 Colour Half Price Motors) FAST DELIVERY Insulated Sectional Door garage door Steel Carteck

Purpose Made CarTeck Centre Ribbed Insulated Sectional Door - Fast Delivery

A 1.38 W/m²K whole door U value, full perimeter weather sealing and secure electric locking when automated, built to your own millimetre sizes and delivered in a maximum of three weeks.

Most garage openings are not a neat standard size. This listing takes the Centre Ribbed door, the most popular of the three CarTeck panel designs, and builds it to your exact structural opening instead of the nearest size off a list. The three colour stock range keeps it inside the fast delivery offer, so a bespoke door no longer means a long wait.

Manufactured to the Exact Millimetre

The steel sub frame and every panel section are made to the dimensions you supply, up to 5500mm wide and 2250mm high. That has a few practical consequences worth understanding before you order.

• You keep the full drive through width: There is no need to pack the brickwork in to suit a smaller standard size, which matters if you are parking a wider modern car or a van.
• No infills or cladding: No timber packers above the door and no UPVC panels down the sides to disguise a gap, so the finished job looks like the door was always meant to be there.
• A better seal all round: The frame sits properly against the brickwork, which gives the perimeter seals a fair chance of doing their job.
• Awkward openings become straightforward: Tapered brickwork, an unusually low lintel or a wider than average opening are all handled at the manufacturing stage rather than on site.

The Delivery Time Is No Longer a Reason to Compromise

This is the part most people miss. A purpose made CarTeck door on this offer is on the same maximum three week lead time as the standard sizes, so choosing an exact fit costs you nothing in time. If you have been about to order the nearest standard size and pack out the difference, it is well worth measuring your opening again and comparing the two options properly.

What the Centre Ribbed Design Looks Like

Each panel section has a single rib pressed along its centre. It gives the door face some definition and shadow without the busier appearance of a fully ribbed panel, and it sits comfortably on both period and modern properties. On a wide double opening the proportions look particularly well balanced.

Choose smooth Silkgrain for a cleaner contemporary face, or Woodgrain for a lightly textured surface that hides everyday marks a little better. Both finishes and all three colours, White RAL 9016, Anthracite Grey RAL 7016 and Black RAL 9005, are the same price on this offer.

Insulation, Weather Protection and Security

The door leaf uses 40mm thick panels with galvanised steel skins either side of a rigid polyurethane foam core. The panel is tested at 0.56 W/m²K, and a complete fitted door of 8ft x 7ft, measured with its panel joints and perimeter seals, achieves a U value of 1.38 W/m²K. Lower figures mean better insulation.

Seals run along the bottom, sides and top of the opening and between every panel section. The bottom seal is flexible EPDM rubber, which takes up small variations in the floor level. On a purpose made door these seals work better simply because the frame is the right size for the opening in the first place.

For security the door closes within steel guide tracks on both sides, and with a Carteck motor fitted the operator holds it shut in the closed position. No separate manual lock is needed for normal everyday use.

Features and Benefits

• Built to your dimensions: Up to 5500mm wide and 2250mm high, made to the millimetre.
• 40mm insulated steel panels: Double skinned with a foam core, keeping the garage warmer and quieter.
• Sealed around the opening: Bottom, side, top and inter panel seals against draughts, rain and debris.
• No outward swing: The door rises vertically and runs back into the ceiling area, so you can park close to it.
• Low headroom installation: 120mm is enough on most sizes, rising to 140mm where double springs are needed on the largest doors.
• Higher track option: The 240mm headroom kit lifts the tracks clear of a gas meter, pipework or similar obstruction.
• Pre assembled spring trays: Springs come preloaded in enclosed steel trays with cables already routed and retained.
• Tested performance: Class 2 to EN 12424 for wind load, EN 12425 for watertightness and EN 12426 for air permeability.

How to Order a Purpose Made Size

The ordering process is slightly different to a standard size door. Use the drop down menus to select the next nearest size up from the width and height you need, which sets the correct price bracket. When you go through to place the order you will be given text boxes to enter your exact millimetre dimensions.

Please read the Measure tab before you order. Behind the opening you need 85mm to 90mm of clear side room each side and at least 120mm of headroom. For an inbetween fit, deduct 180mm from the structural opening width, and deduct 120mm from the height for a manual door or 140mm for standard electric operation. Doors over 2250mm high fitted within the opening need the 3D Profile Kit.

Add a Carteck Motor at Less Than Half Price Until 31st October 2026

Both operators are genuine Carteck belt drive units designed for this door system, and both are available at well under their normal price while the offer runs.

• Carteck MOTOR L60 Belt Drive, £199 instead of £436: A 600N operator with an opening speed of up to 160mm per second, suitable for doors up to 123kg, which covers most single and standard double sizes.
• Carteck MOTOR L75 Belt Drive, £250 instead of £490: A 750N operator at up to 200mm per second, suitable for every size in the range. This is the one to choose on the larger purpose made doors.
• Quiet belt drive: Noticeably quieter than an older chain or trolley operator, which is worth having if there is a room above or beside the garage.
• Handsets included: Two 4 channel handsets with both models, plus a wireless two channel wall switch with the L75.
• Integrated LED courtesy light: Built into the drive unit.
• Automatic locking: The operator holds the door securely closed as part of normal operation.
• myQ smartphone control can be added: The myQ gateway with photocells allows you to open, close and check the door from your phone, with the photocells providing the required safety system.
• Emergency release where needed: If there is no other way into the garage, add the external emergency release so the door can be opened by hand during a power cut.

* Motor prices exclude VAT. Offer applies to selected Carteck operators ordered with this door and ends 31st October 2026.

* Allow the door height plus roughly 350mm to 600mm of clear internal garage depth. A level floor is essential for the best bottom seal and smooth running.

* If the garage is in a coastal or exposed location, ask us about the optional coastal paint treatment before ordering. It is supplied to order and will add to the lead time.

Configuring Your Purpose Made CarTeck Centre Ribbed Sectional Door

Ordering a purpose made door works slightly differently. Use the drop down menus to select the next nearest size up from the width and height you need, which sets the correct price bracket. When you go through to place the order you will be given text boxes to enter your exact millimetre dimensions, and the door and steel sub frame are then built to those figures.

Please read the Measure tab before ordering and double check your structural opening. Once you are happy with the size bracket, work through the options below.

Door Panel External Texture Finish

• Smooth Silk Finish: An even, low sheen surface that sharpens the shadow line along each centre rib, giving the door a cleaner and more modern look.
• Woodgrain Finish: A lightly textured surface which softens the reflection across the panel and hides everyday marks a little better. It works well on brick and rendered properties.

Both finishes are the same price on this special offer.

Outer Fixing Frame Colour

This is the colour of the steel fixing frame, meaning the two side legs and the top head section. Choose Black RAL 9005, Anthracite Grey RAL 7016 or White RAL 9016 at no extra cost.

Most sectional doors are fitted behind the structural opening, so much of the frame ends up hidden behind the brickwork. The inner return edge is still visible though, so it does show. If the door is going within the opening, considerably more of the frame is on view and the colour choice matters a good deal more. In that case, either match the frame to the door panels for the cleanest look, or match it to your window frames.

Door Colour Finish

Choose White RAL 9016, Anthracite Grey RAL 7016 or Black RAL 9005 for the external panels. All three are the same price within this offer.

The centre rib casts a shadow line across each panel, and that line reads differently depending on the colour. On White it is subtle and understated. On Anthracite Grey it is clearly defined without being harsh, which is one reason this combination sells so well. On Black the rib almost disappears in flat light and picks out sharply in low sun.

Where the door faces prolonged direct sunlight, it is better to avoid the darker colours to reduce the risk of panel expansion.

Coastal Paint Treatment

If the garage is in a coastal, exposed or high salinity location, this option is worth considering before you order. Salt in the air will affect a normal painted steel finish over time, and the standard paint warranty does not apply in coastal areas without this upgrade.

The coastal paint treatment covers the outside face of the door panels and the frame. It adds a further layer of paint protection and carries a three year manufacturer's warranty against peeling and blistering of the external panel finish. Normal colour fade, staining and bleed from door hardware are not included.

* Coastal paint treatment is supplied to order and will increase the normal delivery lead time. The extra cost depends on the door size, colour, frame finish and location, so please contact us with your postcode and full requirements before ordering. We will confirm whether the treatment is recommended, the exact additional cost and the expected delivery date.

Even with the upgrade, regular cleaning still matters. Wash the panels, frame, seals and hardware at least monthly in a coastal position, and again after any severe weather.

Installation Position

• Face Fit Internally, holes pre drilled in frame legs: The frame is fixed behind the garage opening against the internal wall. This is the usual method and it gives the widest possible clear drive through opening. Frame legs come pre drilled ready for fixing.
• Fitting within the opening (Inbetween Fit), no holes in frame: The steel frame sits directly inside the brickwork aperture. Useful where there are no suitable internal brickwork returns, or where something inside the garage prevents fitting behind the opening. Remember to allow for the frame legs, head section and fitting tolerance when you choose the ordering size.
• Fitting within the opening (Inbetween Fit), doors over 2250mm high: Doors over 2250mm high fitted within the opening need the 3D Profile Kit, which covers the relevant frame areas for a neater finish. This option carries an additional cost of £187 plus VAT.

Fitted behind the opening you need 85mm to 90mm of clear side room on both sides and a minimum of 120mm clear headroom, or 140mm on very large doors that need double springing.

Inbetween Opening Installation Kit

This kit is needed for an inbetween installation. It supplies the heavy duty brackets that fix the steel sub frame securely within the brickwork opening.

• Yes, doors up to 3000mm wide: £101 plus VAT
• Yes, doors over 3000mm wide, includes twist kit: £125 plus VAT
• No, installing behind the opening: No charge, kit not required

Remote Controlled Electric Operator

This is where the special offer saving sits. Both Carteck operators are heavily reduced until 31st October 2026.

• Carteck MOTOR L60 Belt Drive, £199 plus VAT, RRP £436: A 600N belt drive operator with an opening speed of up to 160mm per second, suitable for doors up to 123kg. This covers the majority of single and standard double sizes. Supplied with two 4 channel handsets and an integrated LED courtesy light.
• Carteck MOTOR L75 Belt Drive, £250 plus VAT, RRP £490: A 750N belt drive operator running at up to 200mm per second, suitable for every size in the range. Choose this on the taller and wider doors, or if you simply want a quicker opening. Supplied with two 4 channel handsets, a wireless two channel wall switch and an integrated LED courtesy light.
• No motor required, using existing motor: No charge. Only choose this where you are keeping a compatible existing operator.
• No motor required, supply black polymer handle and locking: £75 plus VAT. The door is supplied for hand operation with an external handle and manual lock.

Worth knowing: an electric door is not supplied with an external handle or manual locking as standard, because the operator holds the door closed. If you want a manual door you need to select the handle and locking option above.

Optional Motor Control Accessories

• Wireless digital keypad for external use, £120 plus VAT: Opens the door with a personal PIN code instead of a handset. Handy if you run, cycle or want a way in without carrying a remote.
• myQ gateway with photocells, £180 plus VAT: Adds smartphone control through the myQ app so you can open, close and check the door from your phone. The photocells supplied provide the safety system required for operating the door when you cannot see it.
• Additional 4 channel transmitter, £43 plus VAT: Two transmitters come as standard with every Carteck operator, so this is only needed for a third car or an extra household member.

Emergency External Release

If there is no separate side, rear or internal access door into the garage, select the emergency external release. This key operated device disengages the motor from outside during a power failure so the door can be lifted by hand. If the garage does have another way in, you generally do not need it.

Optional Window Designs

Windows can be added if you want daylight in the garage. On a Centre Ribbed door the window row usually sits best in the upper panel section, where it lines up with the rib pattern rather than cutting across it.

Window options are available across all three colours in this offer: White RAL 9016, Anthracite Grey RAL 7016 and Black RAL 9005. Styles and glazing options depend on the door size and panel layout, and windows are priced on application. Please contact us with your door size, colour and preferred window style before ordering.

* Please refer to the Measure tab for full measuring guidance before ordering, and always allow a suitable fitting tolerance. All option prices shown exclude VAT. The motor offer ends 31st October 2026.

CarTeck Centre Ribbed Technical Performance and Specification

The CarTeck Centre Ribbed is an insulated sectional garage door built from 40mm thick double skinned steel panels. Each panel has a rigid polyurethane foam core between galvanised steel skins, with a single rib pressed along the centre line of the external face.

The outer steel skin has a durable coated finish, available in Smooth Silk or Woodgrain texture. The rib is a styling feature rather than a structural one: the rigidity comes from the 40mm double skinned panel and the internal construction.

Sizes

Because the sub frame and every panel section are made to your figures, there is no packing out of the brickwork, no timber infill above the door and no cladding down the sides. You keep the full drive through width and the perimeter seals meet the brickwork properly.

Thermal and Weather Performance

U values vary with door area, so the figure quoted is always for a stated size. The 1.38 W/m²K above is a complete 8ft x 7ft door measured with its joints and seals, not a panel only figure. Lower numbers mean better insulation.

Panel and Door Leaf Construction

• 40mm thick double skinned steel panels
• Galvanised steel skins both sides with a rigid polyurethane foam core
• Coated external finish in Smooth Silk or Woodgrain texture
• Colours: White RAL 9016, Anthracite Grey RAL 7016, Black RAL 9005
• Steel outer fixing frame in Black RAL 9005, Anthracite Grey RAL 7016 or White RAL 9016

Weather Sealing

• Seals fitted at the bottom, both sides and the top of the opening
• Further seal between each individual panel section
• Flexible EPDM rubber bottom seal, which takes up small variations in floor level

A level, sound garage threshold is essential for the bottom seal to work properly. A worn or uneven floor is the most common reason a sectional door lets water or draughts through at the bottom edge.

Headroom, Side Room and Depth

Frame and Ordering Deductions, Inbetween Fit

• Structural opening width: deduct 180mm to establish the ordering width
• Structural opening height, manual door: deduct 120mm
• Structural opening height, standard electric operation: deduct 140mm
• Structural opening height, electric with the additional low headroom fitting bracket: deduct 120mm
• Doors over 2250mm high fitted within the opening require the 3D Profile Kit

Springs and Balance

The CarTeck system uses a multi spring tension arrangement. All single layer spring trays for standard CarTeck doors arrive fully pre assembled from the factory, with the high level tension springs preloaded inside fully enclosed steel trays and the lifting cables already routed and retained by anti twist brackets. The multiple spring system balances the panel weight evenly, and dual retaining cables support the door in all situations.

Hardware and Operation

• Vertical lift on multiple rollers, then back into the garage ceiling area on the tracks
• Door closes within steel guide tracks at both sides of the opening
• Electric doors have no external handle or manual locking as standard, because the operator holds the door closed
• Manual doors require the handle and locking option, supplied as a black polymer external handle with lock
• External emergency release recommended where the garage has no other pedestrian entrance

Electric Operators

Usage and Warranty Summary

• Normal domestic use is defined as no more than five opening and closing cycles per day

• Deliveries into Scotland: please contact us with your postcode before ordering so we can confirm exact timescales and any additional manufacturer costs

Safer, Simpler Installation with Preloaded Tension Springs

Unlike many other sectional garage doors that rely on complex and potentially dangerous high-tension torsion springs mounted directly above the door, the CarTeck system utilises a far safer, multi-spring tension system.

To make installation as straightforward and safe as possible, all single-layer spring trays for standard CarTeck doors are now supplied fully pre-assembled straight from the factory. The high-level tension springs come preloaded within their fully enclosed steel trays, complete with the lifting cables already perfectly routed and retained by anti-twist brackets. This incredibly smart design not only prevents dirt from entering the mechanism, boosting durability, but it also dramatically speeds up the installation process on-site. The multiple spring system evenly balances the weight of the door panels, whilst the dual retaining cables reliably support the door in all situations, meaning it remains safe and operational even in an emergency. Because the springs are safely housed within these steel channels, tensioning the door is significantly safer and easier than wrestling with an exposed torsion spring bar.

If fitting between the opening, please deduct 180mm from the opening width to determine the ordering width.
Deduct 120mm for manual doors and 140mm for electric operation (unless the additional fitting bracket is purchased then 120mm applies) from the opening height to determine the ordering height.

How to Measure for Your Made to Measure Door

Because this CarTeck sectional door is purpose built to your exact millimetre dimensions, accurate measuring is vital. You are ordering the exact internal structural opening sizes. This completely removes the need for timber infills or UPVC cladding to pack out a standard size door.

For a quick visual reference, please look at the 3D technical drawings located in the image gallery at the top of this page. These clearly show how the frame fits in relation to your garage opening.

Measuring for a 'Behind the Opening' Fit (Standard)

This is the ideal and most common way to install a sectional door. The door and its steel framework sit entirely on the inner face of the garage wall, maximising your drive through width.

• Width: Measure the brick to brick width of your garage opening in several places. Your ordering width is simply the smallest of these measurements.
• Height: Measure from the finished floor level up to the underside of the lintel. Your ordering height is this exact measurement.
• Check your clearances: Because the frame sits behind the brickwork, you must ensure you have sufficient internal space. You will need a minimum of 85mm to 90mm of clear side room on both the left and right sides of the opening to accommodate the frame legs.
• Check your headroom: You must also have a minimum of 120mm of clear headroom between the lintel and the ceiling to accommodate the top track and motor. This increases to 140mm for very large doors up to 5500mm wide that require double springing.

Measuring for an 'Inbetween the Opening' Fit

If you do not have internal brickwork returns, the door must be installed directly between the brick pillars using the optional 'Inbetween Opening Installation Kit'.

• Width: Measure your brick to brick opening. To find your ordering width, you must deduct 180mm from this opening size. This allows for the two frame legs and a comfortable fitting tolerance.
• Height: Measure your floor to lintel height. To find your ordering height, you must deduct 120mm (if using the additional low headroom bracket) or deduct 140mm (for standard electric operation without the bracket).

Important Depth Check: Sectional doors travel horizontally into the garage space. It is essential to check that your garage is deep enough to accommodate the full length of the tracks and the motor boom. Ensure you have clear, unobstructed space running back into the garage equivalent to the height of the door plus approximately 350mm to 600mm.

If you have any doubts whatsoever about measuring your garage opening for a custom size door, please contact our team for verification before placing your order.
