Product Overview
Galvanized steel tube, also known as GI square or rectangular tube, is a hollow low carbon steel section coated with a hot-dip zinc layer for excellent corrosion resistance. With square and rectangular cross sections in wall thickness from 1.0 mm to 8.0 มม, our galvanized tubes combine high strength, light weight and easy fabrication, making them ideal for steel structures, fences, frames, guardrails and agricultural equipment.
