Fiberglass Grating

A reliable source for Fiberglass Grating information and leading Fiberglass Grating Companies & Manufacturers.

A grating is any regularly-spaced group of nearly identical, parallel, elongated components. Gratings are used for weight-support devices, as filters over drains and vents, and various other applications. Iron, carbon steel, aluminum, and stainless steel are some commonly-used materials used in gratings. Fiberglass grating, which can also be referred to as fiberglass reinforced plastic (FRP grating), is a lightweight and reliable alternative to steel or aluminum gratings. This product is great for use outside or in hostile industrial settings, because it is both corrosion- and fire-resistant. Read More…

Fiberglass Grating Fiberglass grating is an alternative to other types of grating made from metals or polymers. Fiberglass offers numerous material benefits for applications such as walkways, decking, stair treads, ramps, drain grates and more.

Fiberglass Manufacturing and Properties

Fiberglass is a reinforced plastic material composed of randomly- positioned woven threads and glass fibers that are bonded by a binder agent and combined with a resin. This mixture is heated until molten, then pushed through incredibly small holes to create fiberglass. As a result of this process, incredibly thin glass filaments are produced; these filaments are so thin that their best unit of measurement is the micron (the length of one micron equals the length of one millionth of a meter). There are several uses for these flexible filament threads, including as fiberglass gratings. Fiberglass has an exceptional strength-to-weight ratio and is up to 70% lighter than steel. Even though they are lighter than steel gratings, FRP gratings can still support vehicular applications with sufficient strength. Fiberglass is a good electrical insulator; steel cannot match the electrical resistivity of fiberglass even at much lower thicknesses of fiberglass. Since fiberglass is made of minerals, it is also inflammable by nature.

Types of FRP Grating

FRP Pultruded Grating

Pultruded (pulled) forms can be used to build FRP gratings. Fiberglass rovings and mats are dragged through guides, placed in a resin bath, wrapped in a surface veil, and then pulled through a heated die to create the appropriate bar shape (I-Bars, T-Bars, etc.). The bars are pulled, then they are drilled for cross-rods, and finally, they are put together by attaching the cross-rods. Finally, epoxy is used to bond these cross-rods, which lock the bars into place and guarantee their stability. Although any available resin can be used, pultruded gratings are commonly made using either an isophthalic polyester resin or a vinyl ester resin.

FRP Moulded Grating

This particular fiberglass-reinforced plastic grating is moulded into required shapes. It is a composite material made of laminated fiberglass covered in polyester or vinyl ester resin (to a degree of 65%). This type of Fiberglass Reinforced Plastic grating provides the best strength due to its precise manufacturing process. This FRP grating also has outstanding corrosion resistance across a broad pH range of both acidic and caustic chemicals thanks to its special characteristics. Even in the most severe and corrosive environments, moulded Fiberglass Reinforced Plastic (FRP) grating performs superbly and reliably.

Mini Mesh Fiberglass Grating

The 12 mm (less than a half inch) openings of mini mesh fiberglass grating prevent things from falling through, which makes it perfect for overhead platforms and walkways in commercial and industrial settings. It is long-lasting, low-maintenance, simple to install, and it is highly resistant to slips, fire, and rust. Its small mesh also provides a fiberglass grating which can be used as a pathway without worrying about people's work shoes becoming tangled up in its small apertures.

Applications of Fiberglass Grating

  • Fiberglass grating is utilized in many industrial locations (ladders, stairs, ladders, walkways, etc.) due to its anti-slip and anti-corrosion properties.
  • Cooling towers must be shielded from rust, corrosion, and other safety hazards since they are constantly damp. Fiberglass is employed in these towers as screening material because of its great corrosion-fighting qualities.
  • Fiberglass grating is employed as a barrier to prevent people and animals from entering dangerous areas.
  • Fiberglass grating is used in fountains and aquariums of all sizes to support rocks and aid in the circulation and filtration of water from beneath the rocks.
  • Fiberglass grating is used in large public fountains to shield spray headers and lighting from harm. Additionally, it prevents individuals from perishing in the fountains.
  • Fiberglass grating is used for electronic refining components subject to chemical corrosion where other grating materials would not be suitable under similar situations.
  • Fiberglass's resistance to chemical corrosion is useful in pulp and bleach mills due to high levels of chemicals required to produce these products.
