IGF molded grating reduces installation and fabrication costs because it is lightweight and has bi-axial strength and stiffness. Full panels can easily be handled by two men and the grating can be cut with a rotary saw into complex shapes. Holes can be cut for piping without having to box these cutouts.

Molded grating is very flexible and may be repeatedly deflected without causing permanent deformation. Once the load is removed, fiberglass grating will return to its original shape, unlike metal grating which will remain deformed and require replacement.

The slip resistant meniscus surface of IGF molded grating is created during the molding process by the formation of a concave cross-section on the walking surface. No slip grating has a clear grit applied to the concave surface. Both the meniscus and no slip grit surface are safer than concrete or diamond plate, especially in wet conditions.

IGF Stair Tread features a 1-1/2” x 6” grid, is 1-1/2 “ thick and has a solid leading edge which increases the stiffness and durability. Stair Tread is available in all three IGF resin systems and in a grit finish surface.

IGF also offers a full line of Stainless Steel “J” & “M” clips for installation.

Resin Systems

Because different applications present different requirements, IGF offers three resin systems in our molded grating. IGF VE (Bisphenol Vinyl Ester) provides a maximum level of corrosion resistance. IGF ISO (Isophthalic Polyester) provides an intermediate level of chemical resistance in moderately corrosive environments. For mildly corrosive applications such as marine and waste water, IGF also offers an excellent line of general purpose resin molded grating.
