Core Product Advantages

1. Outstanding Corrosion Resistance: Immune to rust, acid, alkali, salt and industrial chemical erosion, far longer service lifespan than steel and iron pipes.

2. High Strength & Lightweight: Great load-bearing tensile strength while much lighter weight, lowering transportation, hoisting and installation costs.

3. Reliable Insulation & Fireproof: Excellent non-conductive insulation for power projects, built-in fire retardant formula meets fire safety construction standards.

4. Flexible Custom Machining: Custom mold for exclusive sizes, precise cutting and matched assembly fittings to fit unique engineering layout requirements.

5. Low Maintenance Cost: Smooth dense surface resists fouling and aging, no anti-rust paint or regular maintenance needed after installation.

6. Stable Long-Term Durability: Integrated pultrusion molding eliminates internal gaps, maintains consistent structural performance under long-term outdoor buried or exposed usage.

Wide Application Scope

Our pultruded FRP rectangular fiberglass tubing serves multiple heavy-duty engineering fields:

1. Petroleum industry: Oil field support frames, pipeline protection sleeves, offshore auxiliary structural frames
