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

GDO Classic Standard Horizontal Rib - Special Offer

The GDO Classic Standard Horizontal Rib Steel Up and Over Garage Door is a durable, galvanised steel door defined by its traditional "close-boarded" horizontal design. This narrower rib spacing creates a textured, consistent surface that is widely recognised and trusted across the UK, making it an ideal replacement for older doors or a practical choice for new builds.

Design and finish

Finished in a crisp white powder coat on both sides as standard, this door is available in a wide range of standard sizes. The horizontal lines of the standard rib design help to visually widen the appearance of the garage opening, providing a smart and uniform finish that suits almost any architectural style.

Operating gear options

You can select either **canopy** or **retractable** operating gear, which comes factory-fitted to the door chassis. This integrated gear system means the door arrives ready for installation, saving you time and effort compared to assembling complex mechanisms on-site.

Sub frame options

The door is available to order on its own for installation into an existing timber frame, or complete with a factory-fitted steel sub-frame for fixing directly to your structural opening. Please remember that an up and over door cannot be fitted directly to brickwork; it must always be installed with either a timber or steel sub-frame.

Sizing and measuring

Ordering sizes for standard up and over doors always refer to the internal opening size of the sub-frame (the daylight opening). To calculate the full external dimensions, you must add the width of the timber or steel frame to the ordering size. This is critical if you are installing the door and frame between brickwork where tolerances are tight.

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.
