FRP Stair Treads: Engineering Safer Industrial Stairways

Stairways are often the most dangerous part of an industrial facility. When workers are carrying tools or dealing with wet, oily boots, a single slip can cause a serious fall. Steel stairs rust, and once the tread pattern wears down, they become a hazard. That is why many safety managers are switching to FRP stair treads.

Unlike standard walkway grating, a stair tread is a highly engineered component. It must handle dynamic foot traffic, provide maximum traction, and fit perfectly into the stair stringers. This article covers how to specify fibergrate stair treads correctly, from surface texture to fixing methods, so you can upgrade your plant’s safety without overcomplicating the budget.

Why FRP Stair Treads Outperform Steel

FRP stair treads are manufactured using glass fiber and thermoset resin. They offer two immediate advantages over traditional steel treads:

1. Zero Corrosion: FRP Grating will never rust, even in chemical plants or coastal environments. You do not need to sandblast or repaint them.

2. Lightweight Handling: A standard FRP tread is about one-third the weight of a steel tread. This makes them much easier for your maintenance team to handle during installation or replacement, reducing site safety risks.

The Anti-Slip Factor: Grit vs. Concave

Safety is the main reason buyers look for fibergrate stair treads. You cannot rely on standard open flooring in a stairwell.

Most FRP treads use a concave (meniscus) surface, which provides basic slip resistance. However, for stairs, grit surfaces are highly recommended. Abrasive grit is embedded directly into the top resin layer during manufacturing. It acts like sandpaper under a worker’s boot, providing reliable traction even in rain, oil, or chemical spills. Because the grit is molded in, it will not peel off or wear away easily.

Additionally, specifying high-visibility safety colors—such as safety yellow or bright green—helps workers clearly see the edge of each step, reducing tripping hazards.

How to Specify the Right Tread Dimensions

Sizing a stair tread requires more attention than just measuring the gap. You need to consider the depth and the front edge.

• Depth: Standard stair treads are usually 235 mm or 305 mm deep, depending on your stair design.

• Nosing: For added safety, specify a tread with an integrated nosing (a slightly raised or curved front edge). This prevents boots from catching on the riser and provides a clear visual cue for the step edge.

Fixing Methods: Bolts vs. Clips

How you attach the tread to the stringer is critical for long-term durability.

• Heavy-duty Bolts: Often used for heavy traffic areas. However, you must use oversized clearance holes.

• Stair Tread Clips: These clamp the tread to the stringer without drilling through the walking surface.

A crucial engineering tip: FRP expands and contracts with temperature changes. When using bolts or clips, always leave a slight clearance gap to allow for this movement. If the tread is bolted too tightly without room to expand, it may crack in extreme heat or cold.

Installation Tip: Seal the Edges

When your team cuts or drills FRP treads on-site, they expose raw glass fibers. Moisture and chemicals can wick into these fibers and weaken the tread. Always use a resin sealant on any cut edges or drilled holes. It takes two minutes but can significantly extend the lifespan of the tread.
