National Grating fiberglass Square mesh panels are ideal for decking, walkway, and flooring applications in corrosive environments.

1.5″ Square Mesh Grating is the long-lasting solution for rugged applications. Steel and aluminum grating have considerable down-sides; they corrode, wear down quickly, cause maintenance headaches and downtimes, and are costly to install.

National Grating high-strength molded FRP grating can be designed and used like traditional metal grates, but with all the many benefits of fiberglass. 1-1/2″ x 1-1/2″ Square FRP grating is especially useful for replacing steel grating or aluminum grating in corrosive environments or where other types of gratings require frequent replacements. For smaller mesh sizes check out our mini-mesh Fiberglass Grating.

Resin Systems
National Grating Molded Fiberglass is available in two standard resin systems. Each providing different levels of corrosion protection. Both resin systems meet Class 1 Flame Spread Rating per ASTM E-84 test standards.

Polyester: A premium-grade isophthalic polyester resin system that provides excellent corrosion protection. Standard colors: Dark Gray, Light Gray, Yellow, and Green

Vinyl ester: A chemically resistant system that provides the highest level of corrosion protection. Standard colors: Yellow, Dark Gray, and Orange
