EXTREN® is a proprietary combination of fiberglass reinforcements and thermoset polyester or vinyl ester resin systems. It is produced in more than 100 standard shapes. All EXTREN® 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:
EXTREN® 500: An all-purpose series utilizing a premium polyester resin system with a UV inhibitor.
Color: olive green
EXTREN® 525: An all-purpose series utilizing a fire retardant premium polyester resin system with a UV inhibitor.
Color: slate gray (plus certain handrail and fixed- ladder components in yellow)
EXTREN® 625: A premium series – both fire retardant and highly corrosion resistant – utilizing a vinyl ester resin system with a UV inhibitor.
Color: beige
All structural shapes are available in a polyester resin (Strongwell PE) and vinyl ester resin (Strongwell VE) which are certified to NSF-61. Any Series 500, 525 and 625 EXTREN® product can be manufactured upon request to meet the mechanical and physical properties of BS EN 13706 (E23) European standards.
FABRICATING WITH EXTREN®
JOINING – EXTREN® can be fastened mechanically with screws, bolts or rivets. FIBREBOLT® fiberglass studs and hex nuts (available from FABCO) can also be used with EXTREN®. EXTREN® can be joined by adhesives. The strongest connections can be made by using a combination of mechanical fasteners with adhesives. Suggested fabrication techniques for EXTREN® are covered in MFG’s EXTREN® Fabrication and Repair Manual.
