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