Fiberglass Stair Treads

Keep your workforce safe by investing in fiberglass stair treads. Perfect for industrial, commercial, and outdoor residential applications, fiberglass-reinforced plastic stair treads deliver the ideal balance of strength, durability, flex and safety. Shop for our latest molded and pultruded stair treads and stair tread coverings.

Fibertred® Molded FRP Stair Treads

Safe-T-Span® Pultruded FRP Stair Treads

Safe-T-Span® Pultruded FRP Stair Treads

Gray molded fiberglass stair treads installed on a staircase

Molded Fibertred stair treads provide exceptional strength and slip resistance for pedestrians. By installing a fiberglass staircase, business owners reduce liability and signal their concern for employee health. Fibertred's slight flex is more comfortable for workers knees and ankles as it gives when stepped on, unlike aluminum, wood or concrete.


Made with the same glass fibers and resin found in our fire-retardant fiberglass gratings, Fibertred molded treads resist high impacts, corrosion, and chemical exposure. They are available with one of two surfaces: standard meniscus or epoxy bonded mineral abrasive grit.


Fabricators can cut molded FRP stair tread by utilizing the designated channels spaced at 6” intervals. The treads sit 1-1/2” deep with 1-1/2” x 6” mesh and have a solid FRP nosing for sure footing.

Pultruded FRP stair tread with yellow nosing

Bridge the span on a wide FRP staircase with Safe-T-Span pultruded stair treads. With more uni-directional strength than most stair tread products, pultruded treads represent the ideal solution for wide flights of stairs.


Available with I-shaped or T-shaped load bars, Safe-T-Span fiberglass-reinforced treads have a slip-resistant grit surface. They are also corrosion-resistant, non-conductive, and impact-resistant, making them a versatile solution for several major industrial applications.


Color options include dark gray with yellow nosing and yellow grating with dark gray nosing. Pultruded fiberglass stair treads are manufactured in 24 foot lengths before they are cut to size to accommodate FRP staircases of all widths.
