GDO Classic Standard Vertical Rib (White Only) Special Offer Up and Over garage door Steel GDO

GDO Classic Standard Vertical Rib - Special Offer

The GDO Classic Standard Vertical Rib is the definitive "no-nonsense" steel garage door. Its vertical narrow-ribbed design is a staple of British housing, offering a timeless look that is robust, secure, and incredibly easy to maintain. It is the perfect choice for homeowners looking for a simple, high-quality door that does the job without fuss.

Design and finish

Finished in a durable white powder coat on both sides, this door is available in the most common standard sizes to suit single garages. The vertical ribbing not only adds strength and rigidity to the door panel but also helps rain to run off quickly, keeping the door looking cleaner for longer.

Operating gear options

You can choose between **canopy** gear (ideal for manual use where there is no room for ceiling tracks) or **retractable** gear (smooth running and perfect for electric automation). Both gear types come factory-fitted to the door chassis, making installation straightforward and hassle-free.

Sub frame options

This door can be ordered for installation to an existing suitable timber frame, or with a factory-fitted steel sub-frame for fixing directly to the structural opening. Using a steel sub-frame is highly recommended as it removes the need for painting timber and provides a neat, unified finish.

Sizing and measuring

The ordering size for this door is always the internal opening size of the sub-frame (the clear opening). To get the correct external dimensions for fitting, you must add the width of the timber or steel frame to this size. Please refer to the measuring tab to ensure you have calculated the correct overall width for your opening.

These GDO special offer up and over doors are white only, in 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 internal sub 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

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.
• Ordering sizes: Ordered by imperial size references (for example 7’0” x 6’6”, 7’0” x 7’0”) which relate to the closest internal frame opening size.

Construction and finish

• Construction: Galvanised steel door leaf with pressed ribs, folded edges and internal bracing for strength.
• Finish: Factory finished in white only on the door and optional steel frame.

Steel sub frame

• Steel frame: Optional 50mm all round factory-fitted steel box frame in white.
• Sizing with frame: Add 100mm to the ordering width and 50mm to the ordering height to get the overall external frame size.

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

• Can be supplied pre-framed for direct fixing into the opening, or unframed for fixing to your own timber sub frame.
• 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.
• When using the optional steel frame, the door and frame 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.
