Our fiberglass stair tread combines a pultruded FRP structural body with an integrally bonded, grit‑coated nosing. The grit is silicon carbide, which means the slip resistance is built into the tread itself, not a piece of tape that curls up after a season. For plants in chemical processing or coastal washdown areas, this matters. The tread generally delivers the same coefficient of friction under wet, oily, or highly corrosive conditions that would degrade conventional steel treads in months. Slip resistance performance is commonly evaluated under ASTM D2047.
This tread is designed to drop into standard stringer profiles. The 102 mm depth and nosing profile suit 45‑degree industrial stair stringers, and while the tread itself is light enough for one person to carry up a column, the glass‑reinforced structure handles point loads that would twist a typical metal checkered plate. If your site already runs FRP walkway systems, adding the matching tread keeps the corrosion‑resistance chain unbroken.
Standard depth is 102 mm (4 in), suitable for 45° stringers. Surface options include open‑mesh grit top or solid concave grit profile. Fire performance generally achieves a flame spread index ≤ 25 when tested per ASTM E‑84, meeting most industrial insurance requirements. Resin systems include isophthalic polyester as standard, with vinyl ester available for severe chemical exposure. Weight is approximately 2.7 kg per linear 100 mm width.

Proven in Field
"After replacing steel stair treads with FRP versions across the platform, the operator recorded a 60% drop in slip incidents over two years and eliminated recurring repainting—pushing the expected tread life beyond five years."
