Structural Shapes and Plate
EXTREN® is the registered trade name for a proprietary line of standard pultruded fiberglass structural shapes and plate produced by Strongwell. The EXTREN® line consists of more than 100 different fiberglass shapes, each with a very specific, proprietary composite design.
EXTREN® shapes and plate can be identified by the EXTREN® logo embedded in the surfacing veil. All EXTREN® products meet or exceed the minimum published mechanical, physical, electrical, flammability, and corrosive properties of the respective Series published in the Strongwell Design Manual.
EXTREN® is offered in multiple series designed for different environments and applications.
Standard Color: olive green
Standard Color: slate gray
Standard Color: light gray
Standard Color: beige
In addition to the above EXTREN® products, Strongwell manufactures custom pultrusions. These pultrusions vary from EXTREN® in either shape, resin type, or reinforcement (type, amount, location and/or orientation). Designers may choose to vary one or all of these parameters to improve strength, temperature resistance, corrosion resistance, machinability, or some other characteristic. Consult Strongwell with specific needs or questions.
Any Series 500, 525, 600, and 625 EXTREN® product can be manufactured upon request to meet the mechanical and physical properties 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 DURAGRID® grating. Surface grits are available in urethane fine or medium (for light pedestrian applications), as well as epoxy fine, medium, coarse (#4) or extra coarse (#3). 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® is available in 4' x 8' panels in standard EXTREN® plate thicknesses of 1/8", 3/16", 1/4", 3/8", 1/2", 5/8", 3/4", and, 1". SAFPLATE® is available in all standard EXTREN® Series. Custom colors and sizes are available upon request.
