Hot Dip Galvanized Steel Pipe | Q235B Corrosion Resistant Pipe for Construction
Hot Dip Galvanized Steel Pipe | Q235B Corrosion Resistant Pipe for Construction
Hot dip galvanized steel pipe is a mainstream carbon steel pipe with superior anti-corrosion performance. Made of high-quality Q235B carbon steel with hot-dip galvanized coating, it effectively prevents rust and oxidation in humid, coastal and outdoor environments. Widely used in water supply, fire protection, greenhouse construction and structural engineering, our galvanized pipes are hot-selling products for global export projects.
Main Specifications
- Material: Q235B Carbon Steel
- Size Range: DN15 – DN200
- Wall Thickness: 1.5mm – 6.0mm
- Standard Length: 6m / 12m or customized
- Standard: GB/T3091, ASTM A53, BS1387
- Surface Treatment: Hot Dip Galvanized
Product Advantages
1. Excellent Corrosion Resistance
Thick and uniform zinc coating (35–70μm) provides dual physical and sacrificial protection. It resists rust, acid and alkali erosion, with a service life of 20–50 years for outdoor use.
2. High Structural Strength
Solid Q235B steel base ensures strong pressure resistance and impact resistance, no deformation under heavy load and water pressure.
3. Easy Construction & Processing
Smooth surface and precise dimensions support cutting, threading, welding and grooving installation, saving construction time and labor cost.
4. Cost-Effective & Durable
Lower purchase cost than stainless steel pipes and much longer service life than black steel pipes, ideal for large engineering procurement.
Applications
Water supply pipeline, fire fighting system, greenhouse frame, construction guardrail, mechanical threading pipe, municipal engineering structure.
