PROGrate Heavy-Duty Pultruded Grating

Bedford’s PROGrate Heavy-Duty Pultruded (HDP) grating is engineered to carry higher loads than traditional grating. It also delivers the same high-strength, corrosion-resistant performance as our PROGrate pultruded grating products. PROGrate HDP grating is available by special order in 1", 1 1/2", 2" and 2 1/2" thicknesses and gray IFR and VFR resin systems. Made-to-order panels are available up to 5' wide by 20' long.

NOTE: These products are only available by special order. Minimum orders, extended lead times and special-order pricing will apply.

Available Resin Systems

PROGrate HDP grating is available in two resin systems, each providing different levels of corrosion protection. Both resin systems meet Class 1 Flame Spread Rating per ASTM E-84 test standards.

IFR: A premium-grade isophthalic polyester resin system that provides excellent corrosion protection.

VFR: A vinylester resin system that provides the highest level of corrosion protection.

Applications

Flooring, platforms and ramps
Storage areas
Assembly lines
Long-span walkways
Trench covers with vehicular traffic

Features

High strength
Corrosion resistant
Low conductivity
Fire retardant
Low maintenance

NOTES: Allowable Spans for Vehicular Loads

Load is carried by the grating load bars immediately under wheel plus two additional load bars.
Allowable span is based on allowable bending stress and 0.25″ deflection; other criteria may be required by certain construction codes. Check code requirements to determine design criteria.
Allowable span is strongly dependent on wheel width and vehicle load capacity. If your application varies from the values shown on this table, contact Bedford for assistance.
Load based on AASHTO LRFD bridge design Specification, 2 Ed. This does not imply that the allowable span meets the deflection requirements of this specification.
