Company Profile

Cold Formed Welded Structural Hollow Section Tube Square And Rectangular Tube

Product Description

Pre-galvanized steel pipes are manufactured from galvanized steel strips through high-frequency ERW welding technology. With a uniform zinc coating and stable mechanical performance, these pipes are widely used in construction, scaffolding, greenhouse systems, and furniture manufacturing.

Key Features

Uniform zinc coating for corrosion resistance
Smooth surface, suitable for further processing
High precision in diameter and thickness
Strong weld seam with ERW technology
Available in standard and customized specifications
Cost-effective alternative to hot-dip galvanized pipes

FAQ:

Q1: What is the difference between pre galvanized and galvanized steel pipe?

A: Pre galvanized pipe is made from coated strip before forming, while hot dip galvanized pipe is coated after forming, resulting in thicker zinc protection.

Q2: Is pre galvanized steel pipe suitable for outdoor use?

A: It can be used for light outdoor environments, but for heavy corrosion areas, hot dip galvanized pipe is recommended.

Q3: What sizes of GI pipes do you supply?

A: We supply 20mm to 112mm diameter with thickness from 0.7mm to 2.3mm, and support full customization.

Q4: Can you provide customized steel tubes?

A: Yes, we support customized size, thickness, length, and tolerance according to your requirements.

Q5: What industries use pre galvanized steel pipes most?

A: Construction, greenhouse agriculture, furniture manufacturing, fencing, and scaffolding.
