GI Hot Dip Galvanized Circular Welded Steel Pipe
Excellent Corrosion Resistance & Structural Strength – Reliable Support for Global Projects
Product Overview
The GI Hot Dip Galvanized Circular Welded Steel Pipe is manufactured from high-quality hot-rolled or cold-rolled steel strip, formed by high-frequency welding, followed by a hot-dip galvanizing process. The result is a uniform, dense zinc-alloy coating that combines the mechanical strength of steel pipe with the superior anti-corrosion performance of zinc. It is an ideal choice for building structures, fluid transmission, guardrails, agricultural greenhouses, municipal engineering, and more.
Competitive advantage
Superior Corrosion Resistance
The hot-dip galvanizing process creates a uniform, smooth, and seamless zinc layer on both the inner and outer surfaces. The zinc layer forms a metallurgical bond with the steel substrate, offering excellent adhesion and significantly extending service life, even in humid, acidic/alkaline, and outdoor environments.
Excellent Mechanical Properties
High-frequency welding ensures smooth and strong seams, with good roundness and straightness. The pipe offers stable performance under compression, bending, and torsion, meeting structural and fluid transmission requirements.
Standardized Production & Strict Quality Control
Manufactured according to international standards (e.g., ASTM A53, BS 1387, GB/T 3091), with in-line eddy current testing, hydrostatic testing, and coating thickness inspection to guarantee product quality.
Easy Fabrication and Installation
Smooth, burr-free surface allows for threaded, welded, clamped, or socket connections. Suitable for cutting, bending, and drilling, reducing construction time and labor cost.
Eco-Friendly & Cost-Effective
Hot-dip galvanizing is a recognized environmentally friendly surface treatment. With long coating life and low maintenance costs, the pipe delivers outstanding economic benefits over its full life cycle compared to ordinary painted steel pipes.
