Galvanized Steel Rectangular Tube is a metal product made from carbon steel or alloy steel, coated with a zinc layer on the surface to protect against corrosion and oxidation. These rectangular steel sheets typically come in rectangular or square boxes with straight edges and right angles.

The main functions and applications of Galvanized steel rectangular tube include:

1. Construction: A galvanized steel rectangular tube is commonly used to create structural components such as frames, columns, beams, and other mechanical parts in projects like buildings, bridges, and warehouses. The zinc-coated surface layer helps protect the steel from corrosion and extends the structure's lifespan.

2. Piping and Plumbing Systems: A galvanized steel rectangular tube is also used to manufacture pipes and conduits for water, gas, and oil transportation. The corrosion-resistant properties of the zinc coating help safeguard these systems from environmental damage.

3. Energy and Electronics: A galvanized steel rectangular tube can be used in the industrial production of components for electrical and electronic systems, such as electrical cabinets, outlets, and junction boxes.

4. Decoration and Interior Design: In interior design and decoration, galvanized steel tubing can create products like tables, chairs, shelves, and other decorative elements.

5. Automotive Industry: Galvanized steel rectangular tubes can also be used to produce components and parts for the automotive industry.

The zinc-coated surface not only protects the steel from corrosion but also provides a bright and aesthetic finish. This makes galvanized steel rectangular tubes a popular choice in many applications, especially where corrosion resistance and durability are required.
