FRP anti-corrosion purlins are utilized to support building envelopes and transfer structural loads; they are widely employed in construction projects situated in corrosive environments—such as those found in the chemical industry, aquaculture facilities, and coastal regions.
Corrosion Resistance
Lightweight & High Strength
Durable and Reliable
Flexible Customization
FRP purlins are lateral load-bearing components utilized in roofing or wall structures; typically manufactured via the pultrusion process, they serve to support roof and wall panels while transmitting structural loads, making them critical structural elements in industrial facilities and corrosion-resistant building systems.
Key Performance Advantages
· Exceptional Corrosion Resistance
Resistant to corrosion from acids, alkalis, salt spray, and ammonia gas; particularly suitable for environments such as chemical plants and livestock farms.
· High Strength & Lightweight
Weighs only 25%–30% as much as steel purlins, yet possesses excellent load-bearing capacity.
· Anti-Aging & Superior Weather Resistance
Can be manufactured with an added UV-resistant layer, making it ideal for long-term outdoor applications.
· Easy Installation
Can be cut and drilled; utilizes bolted connections, eliminating the need for welding.
· Safe & Insulating
Non-conductive, making it suitable for use in power-related facilities and specialized industrial environments.
· Low Maintenance Costs
Requires no anti-corrosion coatings; remains rust-free and resistant to rot throughout its long service life.
