Pultruded Fiberglass Grating

fiberglass pultruded grating, frp 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.

Here at Marco Specialty Steel, we’re an industry leader in intelligent grating solutions for a broad range of industrial applications. We offer both pultruded and molded products to better serve your needs and to be sure to have the FRP grating that suits your application and expectations.

We’re not just a supplier — we also fabricate our own fiberglass-reinforced plastic products. That gives us greater control over the quality of our products and the amount of customization we can offer. Many of our customers ask us to help them understand the advantages of pultruded FRP over molded FRP. The characteristics of our pultruded fiberglass grating make it suitable for most industrial applications.

Pultruded Fiberglass Characteristics

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).

Our pultruded FRP range includes several standard widths that fit common platform dimensions (including 24”, 36” and 40” and 48”). We offer a range of lengths that can be used as-is or cut down using simple hand tools for your installation. If necessary, we can also offer custom solutions that are based on your drawings or blueprints.

Simply upload your files to our site and our experienced design team will find the pultruded FRP grating that works. As a manufacturer and supplier of our own products, we can offer you competitive fiberglass reinforced grating prices and the support of an experienced team that can answer your questions and provide you a fast quotation for your FRP grating project.

You’ll find that our pultruded grating systems offer an excellent combination of strength and durability in a lightweight design Contact us for more information and to see if pultruded FRP is right for your industrial platform, stairs and grating requirements.

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.
