Pultruded Fiberglass Grating
Pultruded fiberglass grating is manufactured by
assembling two structural fiberglass shapes (cross and bearing bars)
into a grid pattern. These bar shapes are made by a pultrusion - a
continuous molding process utilizing glass or fibrous reinforcement in a
polyester or vinyl ester resin matrix. Selected reinforcement materials
like glass strands, mat or cloth are drawn through a resin where the
material is thoroughly impregnated with a liquid resin. The fibrous
laminate is formed to a geometric shape (T or I) and pulled through a
heated steel die. The laminate solidifies into the exact shape of the
die cavity as it is being continuously pulled by the pultrusion
machine.
- Strength: Pultruded Grating products offer superior strength and stiffness. Since glass is the key contributor to structural performance, pultruded offers the highest strength to unit weight ratio.
- Corrosion Resistance: The degree of corrosion resistance for pultruded grating is superior to stainless steel, aluminum and galvanized gratings.
- Fabrication Features: Many panel sizes allow for greater use versatility with longer spans which may reduce scrap loss.
- Safety Surface: The walking surface of most Pultruded Grating have a coarse epoxy grit bonded to both the bearing and cross bars (unless noted).
Pultruded Grating Fasteners
Type "M" 316 stainless steel hold down clips used to secure panels to a support using two adjacent grating bars for a secure fit.
Type "G" stainless steel hold clips designed to attach grating to any structural member flange, 3/4" or smaller in thickness, with no drilling required.
Type "FB" 316 stainless steel flange blocks fit inside close mesh products allowing for installation of cap screws from the top surface of the grating.
Type "RK" 316 stainless steel fasteners offer effective and more secure means for installing pultruded grating.
