MOQ: | 1000meters |
Price: | USD2.9 - /Kilograms |
Payment Method: | T/T |
Supply Capacity: | 5000meters/day |
Product Overview
These fiberglass reinforced plastic (FRP) square tubes are manufactured through the pultrusion process, offering high strength, corrosion resistance, waterproofing, and thermal insulation. They are the perfect alternative to metal or wood, ideal for marine, chemical, and construction applications in harsh environments.
✔ Corrosion Resistance
Resists acids, alkalis, salt spray, and chemicals, perfect for chemical plants.
✔ Waterproof & Insulation
Low thermal conductivity (≤0.25 W/m·K) prevents condensation, ideal for cold chains/pipeline insulation.
✔ Lightweight & High Strength
1/4 the weight of steel with tensile strength ≥300MPa, excellent load-bearing capacity.
✔ Customizable
Custom sizes , colors, wall thickness, and OEM services available.
Standard Size | Custom sizes available) |
Temperature | -50℃ ~ +120℃ |
Tensile Strength | ≥300 MPa |
Marine Applications:
Guardrails & deck support structures (salt spray corrosion resistant)
Hull reinforcement components
Chemical Industry:
Acid/alkali storage tank brackets
Corrosion-resistant pipe sleeves
Chemical processing equipment supports
Construction Applications:
Curtain wall mullions (lightweight alternative to steel)
Insulated truss systems
Structural elements for weight-sensitive design
