Cold Formed Welded Structural Hollow Section Tube Square And Rectangular Tube

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.
