Stair treads

For treads and landings, use walkway mesh. The raised strands grip in the wet, water drains straight through on outdoor stairs, and one piece of expanded metal has no welds to fail. W50-080 is the walkway mesh we recommend for stair treads; W50-075 has the smallest opening, so small items do not drop through, and W50-110 carries the most load of the three. Treads span between the stringers, so the span sets the load: see the load and span table on the walkways page.

Stair railings and balustrade infill

Infill	Look	Where we supplied it
Fine expanded mesh	Light and fine, hardly blocks the view	Pan Pacific Orchard stair railings (F20-28)
Medium expanded mesh	Rigid, industrial, open sightlines	Porsche Studio and Zouk (M30-30)
Perforated sheet	Flat and clean, privacy set by the hole pattern	Railings on the Dunearn pedestrian bridges and Sceneca Residence

Balustrade infill must meet BCA structural requirements, including opening size and load resistance. Your engineer or QP confirms the design and fixing; we supply to that specification. Infill is typically 2.0mm to 3.0mm galvanised mild steel or SS304.

Feature staircases

At Tai Keng Place, Supply Bay designed, fabricated and supplied a complete staircase built from round and square perforated metal, powder coated in white and black. It was featured in SquareRooms Magazine. Send a drawing or a reference photo for a staircase of your own.

Material for indoor and outdoor stairs

Outdoor stairs: hot dip galvanised steel, or stainless where it must stay looking good. SS316 near the sea.
Indoor stairs: powder coated mild steel or aluminium in any RAL colour.
Cut edges on galvanised steel need a zinc touch up on site, or they rust within days in Singapore humidity.

Frequently asked questions

What mesh is used for metal stair treads?

Expanded walkway mesh. We recommend W50-080 for stair treads. W50-075 has the smallest opening, so small items do not drop through, and W50-110 carries the most load of the three. The raised strands give grip and water drains through.

Expanded metal or perforated stair treads?

Expanded walkway mesh is the standard for treads that need grip and drainage, outdoors and in plant areas. Perforated metal gives a flatter, cleaner surface and suits design led interior stairs, like the perforated staircase we supplied at Tai Keng Place.

Can you make a complete metal staircase?

Yes. At Tai Keng Place we designed, fabricated and supplied a complete feature staircase in round and square perforated metal. Send a drawing or a reference photo for a quote.

What mesh can I use for stair railing infill?

Fine expanded mesh, medium expanded mesh or perforated sheet, depending on how open and how industrial you want it to look. Infill must meet BCA requirements for opening size and load, confirmed by your engineer or QP.

What is the best metal for outdoor stairs in Singapore?

Hot dip galvanised steel for most outdoor stairs, and stainless steel where appearance matters or the stair is near the sea, where SS316 is the right grade.
