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

Fast Delivery CarTeck Centre Ribbed Insulated Sectional Garage Door

A 1.38 W/m²K whole door U value, weather seals all the way around the opening and secure electric locking when automated make this a well insulated and practical garage door for everyday use.

The Centre Ribbed profile is the design we sell most of, and this offer removes the two things that usually hold people back on a German insulated sectional door: the wait and the cost of automating it. Production is limited to three stock colours in a fixed range of popular standard sizes, which brings the lead time down to a maximum of three weeks. Until 31st October 2026 the matching Carteck motor is also available at less than half price.

What the Centre Ribbed Design Looks Like

Each panel section has one rib pressed along its centre line. It gives the door face some quiet definition and shadow without the busier look of a fully ribbed panel, which is why it works on so many different property styles. On a double width door the proportions look particularly well balanced.

You can have the panels in a smooth Silkgrain finish for a cleaner modern face, or in Woodgrain for a lightly textured surface that hides everyday marks a little better. Both are the same price on this offer, as are all three colours: White RAL 9016, Anthracite Grey RAL 7016 and Black RAL 9005.

Insulation, Weather Protection and Security

The door is built from 40mm thick panels with galvanised steel skins either side of a rigid polyurethane foam core. The panel itself is tested at 0.56 W/m²K. Measured across a complete fitted door of 8ft x 7ft, including the panel joints and the perimeter seals, the CarTeck sectional achieves a U value of 1.38 W/m²K. Lower figures mean better insulation.

Seals run along the bottom, both sides and the top of the opening, and there is a further seal between every panel section. Together they keep out most of the draughts, driven rain and leaves that get past an older up and over door. The bottom seal is flexible EPDM rubber, so it can take up small variations in the garage floor.

For security the door closes inside steel guide tracks on both sides of the opening, and when a Carteck motor is fitted the operator holds the door shut in the closed position. There is nothing to lever at the bottom edge and no separate manual lock to remember for normal everyday use.

Standard Sizes, Fast Delivery

This listing covers the standard size range only, which is what makes the three week lead time possible. There are 19 widths from 2084mm up to 5500mm and 9 heights from 1875mm up to 2250mm, and those sizes were chosen because they cover the majority of UK garage openings.

Pick the nearest standard size that fits your structural opening, allowing for the frame and for a sensible fitting tolerance. If none of the standard sizes lands close enough, or you want to keep every millimetre of drive through width, have a look at the purpose made version of this door. It is now on the same three week lead time, so there is no longer any delivery penalty for ordering an exact size.

Features and Benefits

• 40mm insulated steel panels: The double skinned construction and foam core keep the garage warmer and cut down on outside noise.
• Sealed around the opening: Seals at the bottom, sides, top and between the panels help keep draughts, rain and debris out.
• No outward swing: The door lifts vertically then follows the tracks back into the garage ceiling area, so you can park right up to it and keep the full drive through width.
• Low headroom installation: 120mm of headroom is enough on most standard sizes, increasing to 140mm where double springs are needed on the largest doors.
• Higher track option: Where a gas meter, pipework or similar sits close to the opening, the 240mm headroom kit lifts the tracks further inside the garage.
• Pre assembled spring trays: Springs arrive preloaded in fully enclosed steel trays with the lifting cables already routed, which makes installation far more straightforward.
• Tested performance: Class 2 to EN 12424 for wind load, EN 12425 for watertightness and EN 12426 for air permeability.

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

The motor offer runs alongside the door offer and is worth taking while it lasts. Both operators are genuine Carteck belt drive units, matched to this door system rather than a generic operator bolted on afterwards.

• Carteck MOTOR L60 Belt Drive, £199 instead of £436: A 600N operator with an opening speed of up to 160mm per second, suitable for the majority of standard sizes in this range and for doors up to 123kg.
• Carteck MOTOR L75 Belt Drive, £250 instead of £490: A 750N operator with an opening speed of up to 200mm per second, suitable for every size in the range. Worth choosing on the taller and wider doors, or if you simply want a faster opening.
• Quiet belt drive: The belt runs noticeably quieter than an older chain or trolley system, which matters if there is a bedroom above or next to the garage.
• Handsets included: Both operators come with two 4 channel handsets. The L75 also includes a wireless two channel wall switch.
• Integrated LED light: The drive unit has its own courtesy light built in.
• Automatic locking: The operator holds the door securely in the closed position as part of normal operation.
• myQ smartphone control can be added: The myQ gateway with photocells lets you open, close and check the door from your phone. The photocells provide the safety system needed for operating the door when you cannot see it.
• Emergency release where needed: If the garage has no side or internal access door, add the external emergency release so the door can still 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.

* Always check your available headroom, side room and internal garage depth before ordering. Allow the door height plus roughly 350mm to 600mm of clear internal 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 does add to the lead time.

Configuring Your CarTeck Centre Ribbed Sectional Door

Please choose your required width and height first from the standard sizes in the drop down menus. There are 19 widths from 2084mm to 5500mm and 9 heights from 1875mm to 2250mm. Pick the nearest size that suits your structural opening, allowing for the frame and a sensible fitting tolerance, then work through the options below.

If none of the standard sizes lands close enough, the purpose made version of this door is built to your exact millimetre dimensions and is now on the same maximum three week delivery. It is worth comparing the two before you commit to a size.

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

Standard sizes are what make the maximum three week delivery possible. If none of them fits your opening closely enough, the purpose made version of this door is built to the exact millimetre and is now on the same lead time.

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

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.

Need Professional Installation Help?

If you have reviewed the process and decided that a DIY installation isn't right for you, we are here to help. We have a network of trusted, independent garage door installers covering many parts of the UK. We can put you in direct contact with a highly experienced local tradesperson who can survey your garage, discuss your options, and provide a professional installation service to ensure your new CarTeck door operates flawlessly for years to come. Please contact our sales team to find a recommended installer in your area.

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 for the door. Of course you can always fit a smaller height standard door and infill if required.
 

How to Measure for Your New CarTeck Sectional Door

Measuring for a sectional garage door is straightforward once you understand how the dimensions work. All CarTeck sectional doors are ordered by their internal structural opening dimensions (the actual drive-through width and height). Unlike some other door types, the steel installation frame is always calculated as an addition or reduction to these internal dimensions, depending on your chosen installation position.

For quick visual reference, please refer to 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 the 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.

• 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 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 sideroom 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 requiring 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 fitting tolerance).
• Height: Measure your floor-to-lintel height. To find your ordering height, you must deduct 120mm (if installing a manual door or 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, please contact our team for verification before placing your order.
