Galvanized Square Tube

Wanhetong Steel is a premier steel supplier and manufacturer in China, providing Galvanized Steel, Galvanized Sheet, Galvanized Coil, Galvanized Corrugated Sheet, Galvalume Coil, Aluminum Magnesium Coil, Galvanized Round Pipe, Galvanized Square Tube, etc. Galvanized square tube is a common steel material, which is made of steel plate or steel strip after curling and welding, and then hot-dip galvanizing. It has many uses and advantages and is widely used in construction, machinery manufacturing and other fields.

Definition and use

Galvanized square tube is a square or rectangular tube, which is usually made of strip steel after unpacking, flattening, curling, welding to form a round tube, and then rolled from the round tube into a square or rectangular tube. Its code is F (square) and J (rectangular) respectively. Galvanized square tube has the characteristics of high strength, light weight and strong corrosion resistance. It is widely used in construction, machinery manufacturing, automotive accessories, aviation parts, home appliance parts and other fields.

Specifications and sizes

Galvanized square tube has various specifications, with common sizes ranging from 20×20mm to 600×600mm, and wall thickness ranging from 1.3mm to 5.75mm. In addition, there are unequal-sided specifications, such as 20×30mm to 200×200mm, with a wall thickness between 1.3mm and 5.75mm.

Production process

The production process of galvanized square tubes mainly includes the following steps:

Unpacking: Unpack the strip and flatten it.

Curling: Curl the flattened strip into a round tube.

Welding: Weld the round tube into shape.

Rolling: Roll the round tube into a square or rectangular tube.

Shearing: Cut the rolled tube into the required length.

Hot-dip galvanizing: Immerse the formed tube in molten zinc to form a corrosion-resistant protective layer.

Application field

Galvanized square tubes are widely used in many fields due to their excellent performance:

Construction field: Used for support and framework of building structures, such as beams, roof trusses, doors and windows, stairs, etc.

Machinery manufacturing: Used to manufacture various mechanical parts and equipment.

‌Automobile and Aviation‌: Used in automotive parts and aviation components.

‌Industrial Field‌: Used for conveying fluids, gases and liquids, such as oil pipelines, compressed air pipelines, etc.

‌Agricultural Field‌: Used in water conservancy projects and greenhouse construction.

In summary, galvanized square tubes are widely used in many fields due to their high strength, light weight, and strong corrosion resistance.
