Fiberglass Stair Treads manufactured from quality Fibergrate® molded grating exceed tough OSHA standards for safety, strength, durability and corrosion resistance. Fibertred® fiberglass stair treads are available in the same high performance resin formulations as Fibergrate molded grating. This formulation provides excellent safety characteristics slip resistance, non-conductivity and a low flame spread.
Unique cutting channels, spaced at 6” intervals, provide efficient utilization when custom fitting into stairways. These fiberglass molding channels also ensure that all standard stair treads widths (when installed on fiberglass stairs or metal stairs) are terminated with closed ends. A 1-1/2” wide gritted strip is molded into the lead edge of the tread for superior slip resistance. (Additional support is required for stair treads exceeding 42” width).
Cost efficient, durable fiberglass stair treads are slip resistant and non-conductive. These pultruded fiberglass stair treads offer the same level of safety, strength and corrosion resistance as other pultruded fiberglass products. Designed for use in applications where wider support spans are required, pultruded fiberglass stair treads are available in 1”, 1-1/2”, and 2” thickness.
It is suggested that pultruded fiberglass stair tread deflection be limited to span/150. Fiberglass molding deflections based on this ratio are provided at the top of the table. Deflections in the body of the table are for concentrated loads of both 250 lbs. And 500 lbs. A concentrated load is applied at the centerline of the pultruded fiberglass tread, over a width of 4” and a depth of 6”, starting at the stair nosing edge to simulate he landing of a foot. Deflections are not appreciably different due to stair tread depth. Actual depth will vary depending in stair tread configuration.
Covered molded fiberglass grating includes an integral 1/8” grit surface fiberglass plate molded to the top of any molded grating panel. Covered molded grating offers a strong, level surface for foot or cart traffic and provides higher stiffness values than that of open mesh grating. Type “W” hold down fasteners are recommended to secure covered grating panels to structural supports in order to eliminate potential warping of the fiberglass plate. Smooth surface fiberglass grating plate is optional upon request.
FIBERGLASS GRATING PEDESTALS
Specially designed legs for 1-1/2” deep, square mesh molded grating are manufactured to provide sturdy support for elevated flooring. All fixed-height and adjustable legs, support flooring for heights up to 60 inches. (Cross bracing is required for flooring elevated more than 24 inches.) Available molded fiberglass grating legs include:
(A) FIXED-HEIGHT LEGS W/ SINGLE HEAD – For supporting
fiberglass grating up to 60” above level concrete floor.
(C) ADJUSTABLE-HEIGHT MINI LEGS – For raising molded fiberglass structures
3-1/4” to 6-1/4” above uneven concrete floor.
(D) ADJUSTABLE-HEIGHT LEGS W/ SINGLE HEAD – For uneven
floors designed to be screw-adjusted from atop the elevated
(E) ADJUSTABLE-HEIGHT LEGS W/ DOUBLE HEADS – For joining
and supporting molded fiberglass panels above non-level concrete floor.
To maintain corrosion resistance and structural integrity, all exposed ends of fiberglass bar grating or components should be resin sealed after cutting. Peterson offers premium vinyl ester resin sealing kits for its full range of grating products.
Fiberplate® sets the standard for high performance structural panel. A rugged structurally secure fiberglass plate with a molded-in, grit top surface, Fiberplate® is designed for use in applications where durability and long, maintenance-free life is critical. As a fiberglass flooring, FiberPlate is usually installed over structural members, or over existing grating, to provide a solid walkway or to extend the life of a high traffic area. FiberPlate can also be bolted directly to structural beams and used as a wall panel that is resistant to corrosive splash. FiberPlate is manufactured from the same wide range of resins and colors as our molded grating products line. Available fiberglass plate thickness is 1/8”, 1/4”, 3/8”, 1/2” and 3/4” and plate sizes range from 3’-0” x 10’-0” to 4’-0” x 12’-0”. Cut to size pieces are similarly available.
FRP CONCRETE CURB ANGLE
Pultruded fiberglass reinforced plastic (FRP) embedment curb angle provides a secure and durable seat for pultruded grating over concrete trenches and pits. Manufactured from corrosion resistant, gray vinyl ester, fire retardant resin, curb angles are pultruded with a built-in continuous anchor that securely locks the angle into the concrete pour.<
