Structural Shapes and Plate
EXTREN® is a proprietary combination of fiberglass reinforcements and thermosetting polyester or vinyl ester resin systems. EXTREN® 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 multiple series designed for different environments and applications.
An all-purpose series utilizing an isophthalic polyester resin system with a UV inhibitor. Color: Olive Green
An all-purpose series utilizing a fire retardant isophthalic polyester resin system with a UV inhibitor. Color: Slate Gray (plus certain handrail and fixed ladder components in yellow)
A premium series both fire retardant and highly corrosion resistant utilizing a vinyl ester resin system with a UV inhibitor. Color: Beige
Any Series 500, 525 and 625 EXTREN® product can be manufactured upon request to meet the mechanical and physical properties, as well as the dimensional and visual requirements of BS EN 13706 (E23) European standards. All standard EXTREN® products meet and/or exceed the structural requirements of E17 European standards.
All structural shapes are available in a polyester resin (Strongwell PE) and vinyl ester resin (Strongwell VE) which are certified to NSF-61.

- Bridge Decks
- Pool Decks
- Trench Covers
- Odor Control Covers
Materials of Construction
SAFPLATE® is available as solid plate or bonded to DURADEK® or DURAGRID® grating. The standard surface is fine grit. A medium grit or a coarse grit is also available. SAFPLATE® can also be customized to meet the requirements of a variety of applications.
Standard SAFPLATE® has a Class 1 flame rating of 25 or less per ASTM E-84 and meets the self-extinguishing requirements of ASTM D-635.
SAFPLATE® with fine grit is stocked in 4′ x 8′ panels in standard EXTREN® plate thicknesses of 1/8″ and 1/4″. Optional plate thicknesses include 3/16″, 3/8″, 1/2″, 5/8”, 3/4″ and 1″ sizes. Standard SAFPLATE® is Series 525, which is fiberglass reinforced polyester with fire retardant in a gray color. Other resin systems and custom colors are available upon request.
