Stair & Opening Safety Railing Contractor in Saudi Arabia

Choosing the railing system

The infill decides how a railing looks, but the posts, fixings and the structure behind them decide whether it holds. The three systems in common use compare like this:

Handrail height, design load and the size of openings depend on the building type and are set by the Saudi Building Code and the consultant's specification. Confirm all three in writing before ordering: a railing built to the wrong figure has to be rebuilt, not adjusted.

Climate shapes the details too. In Jeddah, salt in the air is the main enemy, so the grade, the finish and the sealing of base plates matter most. In Riyadh, large day-to-night swings make long runs of rail and glass expand and contract, so joints and clamps must allow for movement.

Fixing into the structure

A railing is only as strong as its anchorage. The usual arrangements load the structure differently: posts on a base plate fixed to the top of the slab, posts fixed to the side of the slab or stair edge, and posts set into cores or pockets. Each depends on the distance from the concrete edge, the anchor type and depth, and whether the structure is concrete, steel or timber (see Concrete Structures and Steel Structures).

Where a railing meets a balcony or roof, its fixings also pass through the waterproofing. Plan them before the floor finish and membrane go down, so each post has a sleeve or upstand detailed around it, instead of being drilled through a finished surface afterwards. The railing itself is usually installed last to avoid damage, but its fixing provisions and set-out are agreed early; see Roof Treatment & Waterproofing and Wet-Area Waterproofing.

Checking the railing before handover

Pushing a railing by hand is not a load test. Ask for the checks the specification calls for, and walk the railing with this list:

• Posts are plumb, aligned along the run and show no movement at the base.
• Anchors match the type, size and spacing on the approved drawings, and none sits close to a slab edge unless the design allows it.
• Welds are continuous, ground smooth and treated, with no sharp edges or projecting fixings.
• Glass edges are clean and unchipped, gaps are even and clamps are tightened as specified.
• The handrail is continuous and comfortable to grip, and its ends do not snag clothing.
• Openings between bars, balusters and the stair edge are uniform and cannot be climbed.
• Corrosion protection is intact at cut, drilled and welded points.
• Base plates outdoors are sealed so water cannot collect around the anchors.

Where the specification requires a proof-load test on a sample section, it should be carried out and recorded with the consultant present, not assumed.

What to put in the BOQ

• System type, material and grade, with the finish specified.
• Design load and handrail height, stated as the consultant's requirement.
• Glass type and build-up, taken from the supplier's data.
• Fixing type and anchorage details for each substrate.
• Any proof-load testing and who witnesses it.
• Protection of the finished railing until handover.
