FRP Fiberglass Square Tube 50mm 1.96" x 3ft Structural Composite Tubing 0.18" Wall

Metal structural tubes frequently rust in outdoor moisture, conduct dangerous electrical currents, and add excessive weight to custom builds, while hollow PVC pipes bend and warp under load. Designed to deliver high strength-to-weight performance without corrosion or electrical hazards, this FRP fiberglass square tube 50mm 1.96" x 3ft provides a rugged, machinable composite solution. Manufactured from pultruded fiberglass-reinforced polymer with a heavy-duty 0.18-inch wall thickness, this 36-inch box profile cuts and drills easily with standard power tools to support structural framing, shelving, antenna mounts, and marine fixtures.

Heavy-Duty Composite Strength & Non-Conductive Durability

• Pultruded FRP Composite Construction: High-density fiberglass-reinforced polymer provides superior tensile and flexural strength while remaining significantly lighter than steel.
• 100% Rust-Proof & Chemical-Resistant: Immune to rot, salt spray, industrial chemicals, and outdoor weathering, making it ideal for marine, coastal, and greenhouse projects.
• Electrically & Thermally Non-Conductive: Acts as an insulator against electric current and thermal transfer, making it safe for electrical enclosures, utility poles, and antenna masts.
• Thick 0.18-Inch Structural Wall: Heavy 4.5 mm wall caliper holds fasteners securely and resists crushing and bowing under heavy mechanical loads.
• Easy Drilling & Custom Cutting: Can be trimmed to size with standard carbide saw blades and drilled cleanly for custom brackets, shelving joints, and frames without splintering.
• Precise 50mm (1.96") Square Profile: Sized for modular framing, DIY furniture builds, equipment stands, utility trailers, and architectural structures.
