FRP Grating

 FRP grating refers to Fiberglass Reinforced Plastic grating, it is a type of firm structure made from fiberglass, cast resin and then molded or pultruded into grating plate. This type of grating has outstanding bi-directional mechanical properties, which is stronger than the other types of gratings.

The hole type of FRP grating can be square or rectangular. FRP grating has various specs with different thickness, opening size and overall sizes. The different specs can be used in different applications.

FRP grating has a wide range of applications, such as stair treads, walkways, drainage cover and other applications. Here are all types of FRP gratings for choice. Just choose them according to your requirements. If you have other requirements, just tell us and we will customize them for you.

1. FRP Grating Material: 

1) Fiberglass:

Fiberglass component	Specs	Feature	Applications
non-alkali thick yard	2400 TEX or 4800TEX	Excellent penetration performance with resin matrix solid combination, can make the products with excellent mechanical properties and corrosion resistance	Applied to require high strength and corrosion resistance
medium-alkali thick yard	2400TEX	With excellent penetration, can combine with resin matrix solid, good resistance to acid	Applied to the alkali corrosion environment

 

2) Resin Systems:

Resin Type	Resin Base	Description	Corrosion Resistance	Flame Spread Rating ASTM E84	Available colors	Max. Oper. Temp.
Type VEFR-20	Vinyl Ester	Superior Corrosion Resistance and Fire Retardant	Excellent	Class 1, 20 or less	Dark Gray, Orange	230oF
Type IFR-25	Isophthalic Polyester	Industrial Grade Corrosion Resistance and Fire Retardant	Very Good	Class 1, 25 or less	Dark Gray, Green	221oF
Type FG-20	Isophthalic Polyester	Food Grade Corrosion Resistance and Fire Retardant	Very Good	Class 1, 20 or less	Light Gray, Light Green	221oF
Type CFR-25	Orthophthalic Polyester	Moderate Corrosion Resistance and Fire Retardant	Moderate	Class 1, 25 or less	Green Yellow Light Gray Dark Gray	212oF
Type MP-4	Phenolic	Low Smoke and Superior Fire Resistance	Very Good	Class 1, 5 or less	Reddish-Brown	356oF
Type IFR-10	Isophthalic Polyester	Industrial Grade Corrosion Resistance and Extra Fire Retardant	Very Good	Class 1, 10 or less	Custom	221oF

 

2. FRP Grating Types:

FRP grating has various types for your choice. It can be classified into different types according to the

different standard. The common classification standard is technology and surface. Here are the detailed

types of FRP grating, just refer to them and choose the perfect type suitable for you.

• According to the technology
  • Moldered FRP grating.
  • Pultruded FRP grating.

   

• According to the surface
  • Common surface.
    • Concave surface.
    • Polished smooth surface.
    • Sanding surface.
  • Covered surface.
    • Smooth cover surface.
    • Gritted cover surface.
    • Checker plate cover surface.
