1 MOLDED FIBERGLASS GRATING

2 Molded Fiberglass Grating What is DURAGRATE? DURAGRATE molded fiberglass grating is a strong mesh grating panel that is the chemical resistant flooring choice for many industrial applications. DURAGRATE panels are molded in one piece and feature a concave non-slip walking surface. The costeffective panels allow for efficient on-site cutting to minimize grating waste and load bearing bars in both directions allow for use without continuous side support. DURAGRATE molded fiberglass grating is significantly lighter in weight than metallic gratings and the high resin content (65%) provides long, virtually maintenance-free performance. A higher safety factor is achieved by designing in a higher glass content at the bottom of the grating for greater tensile strength. DURAGRATE molded fiberglass grating is: Corrosion Resistant Low in Maintenance Lightweight Easy To Install Uniform in Appearance Easy To Fabricate Impact Resistant Low in Conductivity Bidirectional Load Bearing Cost Effective Materials of Construction DURAGRATE molded fiberglass grating is composed of fiberglass rovings combined with a choice of five thermosetting resin systems. Standard DURAGRATE grating has a concave profile on the upper surface for skid resistance. Grit tops are available upon request. Standard Resin Systems Available* The Exide Battery Plant in Manchester, Iowa installed corrosion resistant DURAGRATE around its tanks of sulfuric acid.
