Product Introduction

Galvanized Rectangular Tube
Galvanized Rectangular Tube is a hollow steel tube with a rectangular cross-section, which offers excellent rust/corrosion resistance and mechanical strength after galvanization.
Due to its flat cross-section, lightweight structure, and clean appearance, it balances structural support with aesthetics, widely used in building decoration, furniture, machinery, and transport/agricultural facilities.
