DURADEK® and DURAGRID® Fiberglass Stair Treads are made for environments where corrosive resistance and slip resistance are needed. Fiberglass is very lightweight compared to steel and can be made in various colors and resins.
McNICHOLS offers cutting services for any stair tread product. Cutting charges
vary according to the number of cuts.
DURADEK® and DURAGRID® Fiberglass Stair Treads should be supported with struts or a bracing of some type on the bottom flange of stringers. A deflection (the amount of the flexibility in the fiberglass tread when a person stands on it) of 0.25 inches is recommended as the maximum to provide pedestrian comfort, which can be exceeded at the discretion of the engineer.
The strength and corrosion levels of a Fiberglass Stair Tread are determined by the Resin- to-Glass Ratio. The resin component of a stair tread provides the corrosion resistance; the glass component provides the tread’s strength. Therefore, there is a tradeoff between the strength and corrosion of a stair tread depending on your requirements.
The degree of corrosion resistance for a fiberglass stair tread is superior to that of stainless steel, aluminum and galvanized stair treads. Fiberglass Stair Treads are low maintenance and will never rust or need to be painted.
For corrosive environments, a stair tread with a higher level of resin rather than glass (a high Resin-to-Glass ratio) would be appropriate. The Molded Fiberglass Stair Treads would be the product of choice.
Pultruded Grating Stair Tread: High Load Environments
For environments where loading strength is needed, a stair tread with a higher level of glass rather than resin (a low Resin-to-Glass Ratio) would be appropriate. the i-bar pultruded, t-bar pultruded, or MC I Series Pultruded stair treads would be the products of choice.
Pultruded Grating Stair Tread: Safety Surface
Slips and falls on staircases are one of the leading causes of industrial accidents: Fiberglass Stair Treads were designed to reduce such accidents. The majority of Fiberglass Stair Treads are made with a grit surface to provide sure footing for worker safety. A concave (meniscus) or plain surface is available upon request for some products.
The color of the step nosing on the front of the tread typically increases visibility depending on the color of the stair tread. In addition, the open grate configuration allows liquids to drain, and the non-porous qualities of the tread help to eliminate bacterial breeding areas in food applications.
