Fastec International Molded FRP Grating

Fastec’s molded grating is produced in an open, heated mold system, through a a process that creates corrosion-resistance and bi-directional strength. Continuous fiberglass roving is laid in the mold in alternating layers and wetted with a resin uniquely suited to the requirements of each custom application. We offer a wide range of panel sizes, thicknesses, and mesh patterns, as well as colors. All our molded fiberglass grating is ISO 9001:2000 Certified and meets the highest international standards.

Applications:

  • Cooling Towers  (Stick Built, Modular, and Reconstruction)
  • Marine
  • Recreation & Waterparks
  • Water & Wastewater
  • Oil & Gas
  • Chemical
  • Pulp & Paper
  • Mining
  • Electrical
  • Architecture
  • Custom Applications

Molded FRP Grating Literature

The Benefits of Molded FRP Grating:

High Loaded Strength
Our continuous fiberglass strand alternating layers and one-piece construction distributes loads to bi-directional bars for greater tensile strength.

Impact Resistant
Unlike metallic grating, which will deform and need replacement, our molded fiberglass grating allows for repeated deflections without any permanent damage.

Anti-Corrosion, Attractive, & Low Maintenance
Inherent properties in our molded grating, like corrosion/rust resistance from high resin content, and molded-in color and UV resistance means freedom from painting and/or coating, as well as a longer lifespan for your applications.

Lightweight & Easy to Install
At about one-fourth the weight of steel, a full panel of our molded grating can easily be lifted and moved by two people, as well as readily cut to fit your applications using a commercial saw instead of industrial-grade equipment.

Non-Conductive & Non-Sparking
Perfectly suited for electrically hazardous locations or conditions, our molded grating has inherent insulating properties that reduce the risk of electrical shock. It is also well-suited for many applications where sparks can trigger explosion or fire due to combustible gases build-up.

Anti-Fire
All of our resin systems have a Class 1 flame spread rating of 25 or less per ASTM E84.

Anti-Slip Surface
With multiple surfacing options, our molded grating can offer maximum slip resistance designed specifically for your application. The built-in concave surface offers protection, while the gritted surfaces provide superior protection for less wear and tear.

Chemical & UV Resistant
Our molded grating process ensures excellent resistance over a wide PH range – both acidic and caustic, as well as protection from ultraviolet rays.
