Key Features & Benefits
High Strength-to-Weight Ratio: Delivers structural strength comparable to steel while weighing up to 75% less, making transportation and manual handling significantly easier.
Corrosion & Chemical Resistant: Built with high-grade resin formulations to withstand harsh acids, alkalis, salts, and moisture without rusting, rotting, or flaking.
Non-Conductive & Flame Retardant: Non-magnetic with high dielectric strength for safe electrical insulation; fire-retardant options available to meet ASTM E-84 Class 1 standards.
UV & Weather Resistant: Integrated with UV inhibitors and synthetic surfacing veils for maximum resistance to outdoor weathering and thermal expansion.
Easy Fabrication & Installation: Can be easily cut, drilled, and joined using standard tools without standard welding equipment or hot-work permits.
