Fiberglass Structures

Many features of pultruded grating that are critical to industrial applications have been compared on a point-for-point basis to molded fiberglass, aluminum and steel gratings.

DURADEK® and DURAGRID® gratings are lightweight and, therefore, easily handled in installation, and cost less to ship than steel grating. A patented 3-piece cross-rod system mechanically locks and chemically bonds the cross-rods to the web of each bearing bar. This separates and affixes bearing bars firmly in position and distributes concentrated loads to adjacent bars. The system allows DURADEK® and DURAGRID® grating to be cut and fabricated like a solid sheet.

Standard carpenter's tools with abrasive cutting edges may be used; just coat the cut ends with resin sealer and install.

EXTREN® is a proprietary combination of fiberglass reinforcements and thermosetting polyester or vinyl ester resin systems. It is produced in more than 100 standard shapes and all shapes have a surface veil to protect against glass fibers penetrating the resin surface in service and to increase corrosion and UV resistance. EXTREN® is offered in three series designed for different environments and applications.

Corrosion Resistant
Impact Resistant
Low Electrical and Thermal Conductivity
Non-skid Surface
Easily Fabricated in the Field
