GDO Classic Georgian Special Offer Up and Over garage door Steel GDO

GDO Classic Georgian Steel Up and Over Garage Door

The GDO Classic Georgian brings timeless architectural elegance to your home with deeply pressed, raised and fielded rectangular panels. While ribbed doors offer a linear, functional appearance, the Georgian panelled layout adds depth, texture, and character to your front elevation. It is the natural choice for Georgian, Edwardian, and neo-classical properties, as well as suburban executive homes where panelled detailing coordinates with multi panel composite front doors and multi-pane casement or sash windows.

Pressed in the UK from premium grade galvanised sheet steel, each panel recess creates inherent structural rigidity across the door leaf, eliminating oil-canning and resisting wind deflection. Finished with an electrostatic polyester powder coating on both sides, the door delivers the refined appearance of traditional joinery panels without any of the cracking, flaking, or seasonal swelling associated with timber.

Pre-Fitted 50mm Steel Sub Frame Included

Every GDO Classic door arrives pre framed as a complete unit as standard. The 50mm steel box-section sub frame is fitted directly to the door leaf and operating gear at the factory:

• Factory Pre-Assembled Alignment: The side tracks, pivot arms, and counterbalance spring assemblies are pre-mounted and balanced to the steel frame at the factory. This cuts installation time in half, eliminates the need to build up gearing on site, and guarantees true square alignment straight off the lorry.
• No Timber to Rot: Modern galvanised steel eliminates traditional timber goalpost frames that draw damp from ground level, twist out of square, and demand regular repainting.
• Seamless Colour Coordination: The steel sub frame is powder-coated in the exact same colour as the door leaf, creating a neat, matching picture-frame border around your opening.

Crucial Measuring and Sizing Information

All GDO up and over doors are ordered by their Overall Width and Overall Height, which includes the 50mm factory steel sub frame. Choosing your size depends on whether you install within or behind the aperture:

• 8 Standard UK Widths Across 2 Heights: Available in 6ft 6in, 6ft 10in, 7ft 0in, 7ft 1in, 7ft 3in, 7ft 5in, 7ft 6in, and 8ft 0in nominal widths, paired with 6ft 6in (2031mm overall) or 7ft 0in (2184mm overall) height options. The number of panel columns scales symmetrically across width options to maintain balanced proportions.
• Fitting Behind the Opening (Internal Face Fit): Fixes flat to the rear face of the brick piers, keeping your full structural opening clear for maximum drive-through width. Make sure you have at least 50mm of flat pier face on each side and 50mm lintel headroom inside. Important check: Ensure the internal daylight opening of the door frame (the space the door panel swings through) is smaller than the brick opening so the moving panel clears the masonry cleanly without catching.
• Fitting Between the Opening (Between Fit): The frame fits directly between the brick jambs. Your brickwork opening must be slightly larger than the overall frame width and height to allow for installation clearance (we recommend allowing roughly 10mm on the overall width and 5mm on the overall height).

Operating Mechanism: Canopy vs Retractable

Match your operating gear to your garage layout and daily use:

• Canopy Operating Gear: Operated by an overhead torsion spring mounted across the head of the frame with high-tensile cables and steel rollers running in vertical side tracks. When open, approximately one third of the door panel protrudes outward to create a canopy. Because there are no tracks running back into the garage, canopy gear leaves your entire ceiling space completely clear for overhead shelving, ladders, or roof boxes. Engineered primarily for light, balanced manual hand operation.
• Retractable Operating Gear: Uses heavy-duty side-mounted tension springs and horizontal ceiling-level tracks that project back into the garage. The entire door panel glides smoothly inside the building when open, leaving no panel protruding outside. Retractable gear is the required choice if you plan to add a remote-controlled electric boom operator, and it delivers effortless manual travel.

Factory Powder-Coated Colour Options

Every GDO Classic Georgian door is supplied factory-coated in Traffic White (RAL 9016) as standard, or in your choice of 18 low-gloss solid powder-coated colours across both the panel and the matching 50mm steel sub frame:

Fittings, Mechanical Locking & Security

• Two-Point Slam Latching: Fitted with an ergonomic black exterior handle and interior turn disc operating solid mechanical slam-action latches that bite into the steel frame legs.
• Euro Profile Cylinder: Supplied with a standard euro-cylinder lock and 2 keys. Can be keyed alike to matching GDO side personnel doors on request.
• Electric Automation Ready: Retractable models link directly to any good quality ceiling-mounted boom operator (such as the GDO 800XL or Hormann ProMatic/SupraMatic). An optional de-latch kit can be added to retain mechanical lower frame locking alongside the motor boom lock.

GDO Steel Up and Over Size Conversion Chart (Canopy or Retractable)

Use the conversion table below to match your imperial order reference to the exact overall frame dimensions (including the 50mm steel sub frame). Both canopy and retractable operating mechanisms share the exact same overall dimensions.

These GDO special offer up and over doors are standard sizes only, and you choose canopy or retractable gear when you start the order. Standard up and over doors in the UK are ordered using imperial size references, which relate to the nearest overall frame dimensions, rather than exact metric conversions.

Canopy or Retractable Gear

The first decision is whether you want canopy or retractable operating gear. Canopy gear uses a preassembled torsion spring above the door panel with cables either side to lift the door, and when it is fully open about a third of the panel projects out of the front of the garage, which is where the “canopy” name comes from.

Retractable operating gear uses lifting arms either side with springs and horizontal tracks inside the garage, so the door swings out a little further on the way up but then retracts fully back into the garage on the tracks. This makes retractable gear the better option if you know you want to add an electric operator, assuming you have enough headroom and length inside the garage for the boom.

Handle Options

You can choose a standard black handle with euro profile cylinder locking, or no handle and no handle hole drilled at all. No handle is usually chosen when the door is going to be used with an electric operator so you are not left with an unused external handle and keyhole.

Most other up and over door ranges come pre-drilled for a handle as standard, so being able to order the panel undrilled is a useful option when you are planning automation.

Factory Fitted Steel Sub Frame

The door is supplied with a factory fitted steel box section sub frame as standard.
The steel sub frame is 50mm wide all round on these steel up and over doors. 
The ordering size is the overall frame size. 

4 Point Internal Locking

Standard specification is 2 point internal locking, giving locking points at the usual two corners of the door. You can upgrade to 4 point internal locking, operated from the internal handle via cables, and this system can still be fully in place and working even if you don’t have an external handle fitted. This option is mainly for people who want better mechanical security on a manual door, or who are automating but still like the reassurance of proper internal locking.

Colour and Sizes

These are special offer models, so they are white, black and anthracite as standard but also available in 29 alternative colurs for a surhThe ordering size is the overall frame size. 

Door type and operation

• Type: Single skin steel up and over garage door with canopy or retractable lifting gear.
• Operation: Manual as standard, with retractable gear the better choice if you plan to add an electric operator.
• Sizes: Standard sizes only, no made to measure on this range.

Construction and finish

• Construction: Galvanised steel door leaf with pressed ribs, folded edges and internal bracing for strength.
• Finish: Factory finished in a choice of 31 colour options on the door and optional steel frame.

Steel sub frame

• Supplied pre-framed as standard.

Operating gear options

• Canopy – Overhead torsion spring and cables, with about one third of the door projecting out when open.
• Retractable – Side arms and horizontal tracks, the door retracts fully into the garage and is well suited to electric operators.

Locking

• 2 point internal locking as standard.
• 4 point internal locking upgrade, using cables from the internal handle to operate extra locking points (no exposed locking rods).

Handle options

• Standard black external handle with euro cylinder for manual use.
• Or supplied without handle and without handle hole for electric operation.

Installation

• A level floor and square, plumb opening are important for the best results and smooth door operation.

Installation guidance

• These doors should be fixed to a sound, square and level opening, whether you are using the factory-fitted steel frame or your own timber frame.
• Always check the floor is level where the frame legs sit; any fall in the floor will affect how well the door closes and seals.
• Allow a small amount of fitting tolerance around the overall frame size to pack, plumb and level the frame properly before final fixing.
• The door and frame will arrive pre-assembled. Offer the frame into the opening, wedge and support it, then check with a spirit level on the head and both legs before drilling and fixing.
• Fixings should be suitable for the wall type (for example, concrete screws, frame fixings or sleeve anchors into brick or block). Use several fixings down each leg of the frame rather than relying on just a couple near the top.
• With a timber sub frame, make sure the timber is straight, treated and securely fixed to the structure before you hang the door to it. The door gear then fixes back to the timber uprights and head.

Space and clearance

• Check you have enough headroom inside the garage for the chosen gear: canopy needs space above the opening for the spring shaft, and retractable needs extra headroom and depth for the horizontal tracks and any electric operator boom.
• Make sure there is enough clear space in front of the garage for the door to swing out fully during operation, especially with retractable gear which swings out a little further on the way up.

General advice

• Two people are strongly recommended for handling and positioning the door and frame safely.
• After fixing, check the door runs freely, latches securely and sits evenly against the frame; adjust as needed before fully tightening all fixings.
• Basic maintenance such as light oil on pivots, rollers and moving parts will help the door run smoothly and extend the life of the operating gear.
