GDO Narrow Rib Horizontal Pedestrian Gate (32 Colour Options) garage door Steel GDO

GDO Standard Rib Horizontal Pedestrian Gate

For a side gate that feels solid under hand and keeps its shape year after year, the material choice is key. Traditional timber can look the part at first, but it needs regular care and is easily affected by the weather, which often leads to sticking, sagging or splitting. Lightweight aluminium avoids some of the maintenance, but it can flex more and does not always give the reassuring sense of strength you want at a main access point.

This GDO Standard Rib Horizontal Pedestrian Gate uses a fully steel construction with a double skinned gate leaf, so it behaves much more like an external door than a typical garden gate. The rigid build helps it remain true and correctly aligned, resisting warping in hot spells and movement after heavy rain. Combined with a durable powder coated finish available in 32 colours, it offers the security and stability of steel with the kind of finish choice you would normally expect on front doors, making it a very sound alternative to timber or aluminium side gates.

Contemporary Horizontal Rib Appearance

The horizontal narrow rib pattern gives this gate a smart, modern look that suits a wide range of properties. The clean lines run from side to side, creating a more contemporary feel than many vertical boarded designs, and work particularly well where you already have horizontal details on cladding, fencing or garage doors. Matching steel posts and crisp edges complete the framed appearance, helping the gate sit neatly between brick or block pillars.

Robust Double Skinned Steel Construction

The gate is built entirely from steel, including both the leaf and the side posts, providing a firm and reassuringly weighty feel when opened and closed. A double skinned leaf, with steel panels on both faces, gives extra stiffness and reduces flex, which is especially important on wider openings or exposed locations. This construction offers far greater resistance to impact and attempted forced entry than thinner single-skin panels or lightweight garden gates.

Steel also copes far better with the changes in temperature and moisture that cause problems for timber. There is no swelling, shrinking or twisting in damp or hot conditions, so the gate is far less likely to catch on the floor or frame over time. It provides a dependable, door-like operation that suits busy side paths and access routes around the home.

32 Colour Choices for Better Matching

A key advantage of this model is the wide palette of 32 powder coated colours. Many metal gates are offered in one or two basic finishes, which limits how well they can be matched to existing doors, windows and garage doors. With this range, you can pick out a close match to surrounding joinery, or choose a contrasting shade that still looks deliberate and well thought through.

The powder coated finish is tough and low maintenance, so there is no need for regular painting or staining as there would be with timber. An occasional wash down is usually enough to keep the gate looking fresh, making it well suited to homeowners who want a clean, modern appearance without the ongoing upkeep.

Made to Measure for Your Opening

Each gate is produced to size, rather than forcing you to adapt the opening to suit a fixed standard panel. Overall widths from 800mm up to 1300mm, including the posts, cover most typical pedestrian side entrances and pathways. This helps achieve even gaps and a neater finish, especially when fitting between existing masonry.

Two sensible standard heights are available, 1200mm and 1800mm, so you can opt for a lower gate where visibility and openness are preferred, or a taller version when you want more privacy and a greater sense of security. The horizontal ribs run consistently across the face of the leaf to maintain the visual effect at either height.

Everyday Use and Hardware

The hardware is chosen to suit the heavier double skinned steel leaf, with sturdy hinges designed to support the weight of the gate while allowing smooth, controlled operation. A modern black lever handle complements the horizontal panel layout and is straightforward to use for all members of the household. The key-operated locking system gives sensible day-to-day security for side paths, rear garden access and shared passageways.

Fitting Requirements

This gate is intended to be fixed to solid structures on both sides, such as brickwork, blockwork or appropriate steel supports. A stable, well-built opening is essential to take full advantage of the rigid steel construction, helping to keep the gate correctly aligned and operating smoothly over the long term.

Understanding Your GDO Steel Pedestrian Gate Options

Choosing one of these steel side gates is straightforward once you understand the few key decisions you need to make: size, colour, handing and opening direction. The gates are made to measure, so you end up with something that looks and feels more like an external door than a loose-fitting garden gate.

1. Working Out Your Gate Size

Everything starts with measuring the opening where the gate will go.

• Measure the clear width between your walls or posts in millimetres.
• Measure the clear height from finished floor level up to the underside of any lintel or top structure.
• Check the opening is reasonably square and plumb, as large variations may need correcting before you order.

On the product page you will see drop-down boxes for width and height.

• Choose your gate model first, whether that is Narrow Rib Vertical, Narrow Rib Horizontal, Medium Rib Vertical or Medium Rib Horizontal.
• In the width drop-down, select the next size up from your actual opening width.
• Then choose the height from the drop-down that best suits your opening and the look you want.

At checkout there will be a box where you enter the exact ordering width you require.

• Type in the precise overall width you want the gate and posts made to.
• This dimension includes both posts and the gate leaf.
• No fitting tolerances are added, so what you enter is what is manufactured.

This means you must allow your own fitting tolerances when deciding the final size. For example, if your brick-to-brick width is 1000mm and you want 5mm clearance each side, you would order a 990mm overall gate and post width.

2. Choosing Your Colour

All four designs share the same generous colour palette, which is one of the main advantages over many standard off-the-shelf gates.

• You can choose from 32 powder coated colours.
• The colour you pick is applied to the entire visible gate, including both sides of the gate leaf and both posts.
• This makes it much easier to coordinate with garage doors, windows, front doors and cladding.

If you are unsure which finish to choose, a close match to the garage door or front door usually gives the most coordinated look. A darker neutral shade can also work well where you want the gate to sit quietly against brickwork rather than stand out.

3. Handing - Left or Right

You will be asked to choose a handing for the gate. This simply tells the factory which side the hinges will be on and which side the handle will sit.

For these gates, handing is always taken from the non-hinged side, which is assumed to be the external face of the gate.

• Stand outside your property on the side you normally approach the gate from.
• Face the gate from the handle side, not the hinge side.
• Then decide which side you want the hinges to be on.

• Left hand means the hinges are on your left and the handle is on your right.
• Right hand means the hinges are on your right and the handle is on your left.

The outside face gives the cleaner appearance, while the inside face will show the hinges once the gate is fitted.

4. Opening Direction

You also need to decide whether the gate should open inwards or outwards.

• Inward opening is the standard option and means the gate swings into your property.
• Outward opening is available where you have an obstruction inside or limited room for the gate to swing inwards.

Before choosing, it is worth checking the full swing of the gate so it does not foul walls, steps, bins, pipework or a sloping drive. If the gate opens towards a shared path or public access route, you should also make sure it will not create an obstruction.

5. Picking Your Design

Once the practical choices are sorted, it is simply a case of choosing the panel style that best suits the property.

• Narrow Rib Vertical - slim, closely spaced vertical ribs for a neat, modern look.
• Narrow Rib Horizontal - slim horizontal lines for a more contemporary appearance.
• Medium Rib Vertical - usually three broader vertical grooves for a minimalist, door-like design.
• Medium Rib Horizontal - fewer, wider horizontal ribs for a stronger and more architectural look.

All four designs share the same core specification, so the decision here is mainly about appearance rather than build quality.

• Fully steel construction with a double skinned gate leaf.
• Matching steel posts included.
• Choice of 32 colours.
• Made to measure from 800mm to 1300mm overall width.
• Two practical height options at 1200mm and 1800mm.

6. Delivery and Basic Fitting

Once you have chosen your size, colour, handing and opening direction, your new gate will be manufactured to order and delivered ready for installation.

• The gate posts are supplied separate from the gate leaf.
• The posts are fixed first, making sure they are plumb and correctly spaced.
• The gate leaf is then hung onto the posts and aligned.
• The standard black lever/lever handle is supplied for simple assembly once the gate is hanging correctly.

As with any made to measure steel gate, careful measuring and a sound fixing structure are essential. Taking the time to get the ordering size right will give you a better fit, a neater finish and smoother operation once the gate is installed.

Installing Your GDO Steel Pedestrian Gate

These pedestrian gates are designed so that a competent DIYer or general tradesperson can install them without anything too specialist. The main part of the job is fixing the two steel box section posts accurately, as once they are level, plumb and aligned to each other, hanging the gate itself is quite straightforward.

Prepare the Opening

Before starting, check that the structure you are fixing to is sound and suitable for taking the gate posts.

• Make sure the brickwork, blockwork or other supporting structure is solid.
• Check the floor level and allow for the gate swing and any ground clearance needed.
• Confirm the hinge side, latch side and opening direction before fixing anything in place.
• Have a spirit level, drill, suitable fixings, packers and hand tools ready before you begin.

Fixing the Steel Posts

The first and most important stage is fitting the two galvanised steel box section posts. If the posts are set correctly, the rest of the installation becomes much easier.

• Offer the posts into position and check the overall width matches the ordered size.
• Fix each post securely to the supporting structure.
• Use a level to make sure both posts are perfectly upright.
• Check that the posts are aligned with each other and that the spacing is consistent from top to bottom.

Taking a little extra time here is well worth it. Dead level, properly aligned posts will make the hanging and final adjustment of the gate far simpler.

Hanging the Gate Leaf

Once the posts are fixed correctly, the gate leaf can be positioned and hung onto the hinge side post.

• Support the gate leaf in the opening using packers or wedges at the correct height.
• Line the gate up so that the clearances look even around the leaf.
• Fix the hinges to the gate post and check the gate swings cleanly.
• Open and close the gate carefully to make sure there is no rubbing or binding.

At this stage you are aiming for a smooth initial fit. Final tuning can then be carried out using the adjustable hinges.

Adjusting the Hinges

The black aluminium hinges are adjustable by up to 15mm each, which helps when the opening is not perfectly square or when small corrections are needed during fitting.

• Use the hinge adjustment to even up the gaps around the gate leaf.
• Make small changes gradually rather than over-adjusting in one go.
• Recheck the gate swing after each adjustment.
• Continue until the gate opens, closes and latches neatly.

This adjustment feature is particularly useful in real-world openings where walls and reveals are not always perfectly true.

Handle and Lock Fitting

Once the gate is hanging correctly, the handle and lock can be assembled.

• The gate is supplied with a standard black lever/lever handle system.
• The handle set is fitted once the gate is in place and hanging correctly.
• The stainless steel single-point deadlocking system should then be checked for smooth engagement.
• Make sure the latch and lock line up properly with the closing edge before final tightening.

Final Checks

Before finishing the job, it is worth running through a few final checks to make sure everything is operating as it should.

• Check the posts are secure and all fixings are tightened properly.
• Make sure the gate opens fully in the chosen direction without obstruction.
• Confirm the handle operates smoothly and the lock engages cleanly from both sides.
• Check the gaps around the gate are tidy and consistent.

In simple terms, if you are comfortable fixing two steel posts accurately to a solid structure and setting them level and true, you are already most of the way through the installation. Once that is done, hanging the gate and adjusting it into position is a very manageable job for most practical homeowners or installers.
