Molded Fiberglass Grating

Overview

IGF molded grating is available in a variety of standard sizes and colors. Custom colors and panel sizes are available upon request. All grating that carries our name is manufactured in our own ISO registered facility. Molded Fiberglass Grating is commonly used in a variety of applications including but not limited to : Chemical Storage Elevated Walkways Floorings Plating Lines Sump and Trench Covers

Benefits of Molded FRP Grating

  • Corrosion Resistant
  • Ease of Installation
  • Fire Retardant
  • Slip Resistant
  • Nonconductive
  • Low Maintenance
  • Impact Resistant
  • Long Life
  • UV Resistant
Corrosion ResistantIGF molded grating is available in three resin systems for a wide range of corrosion resistant properties. IGF vinyl ester grating is our premium grade and has the widest range of chemical resistance. IGF isophthalic grating has an excellent chemical resistance including solvent resistance. IGF general purpose grating is ideal for mildly corrosive environments such as marine and waste water and is very competitively priced. Whether exposed to continuous submersion, splash, spills, fumes or gases, IGF molded grating outperforms steel and aluminum grating.
Slip Resistant 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. The no slip fiberglass grating has a coarse clear grit applied to the surface. Both the meniscus and no slip grit surface are safer than concrete or diamond plate, especially in wet conditions.
Lightweight & Bi-Axial 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. Unlike steel grating, which must be cut with a gas torch, IGF molded grating can be cut with a rotary saw. Because IGF molded grating has bi-axial strength and stiffness, it can be cut to complex curved shapes without adding extra supports.
IGF 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.
