galvanized pipe

Detailed introduction of galvanized square pipe:

1. Structural characteristics

- Section shape: square or rectangular, side length ranging from 10mm to 500mm, thickness from 0.8mm to 20mm.

- Material: Usually used Q195, Q235, Q345 and other low carbon steel or low alloy steel.

- Galvanizing layer: there is a layer of zinc plated on the surface, and the galvanizing method is divided into two kinds: hot dip galvanizing and electric galvanizing. The hot dip galvanizing layer is thicker and has stronger corrosion resistance.

2. Production process

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

1）Molding: The steel plate is processed into a square or rectangular cross-section by cold bending or hot rolling process.

2）Welding: Adopt high frequency welding or argon arc welding to weld the joints.

3）Galvanizing:

- Hot dip galvanizing: the square tube is immersed in the molten zinc solution to form a uniform zinc layer.

- Electrogalvanizing: depositing a layer of zinc on the surface of the square tube by electrolysis.

4）Post-treatment: including cooling, straightening, cutting and other processes to ensure dimensional accuracy and surface quality.

3. Main features

- Corrosion resistance: The galvanized layer effectively isolates air and moisture, prevents steel pipe rust, and extends service life.

- High strength: the square pipe structure is stable, excellent bending and compression resistance.

- Aesthetics: the surface of the galvanized layer is smooth and has a certain decorative effect.

- Light weight and high strength: light weight but strong carrying capacity, easy to transport and install.

- Economical and practical: galvanized processing cost is low, cost-effective.

4. Application field

- Construction field:

- Used for frames, supports, stair railings, etc. of steel structures.

- Used for light structures such as greenhouses and sun rooms.

- Other areas:

- Used for advertising bracket, guardrail, fence, etc.

5. Install and connect

- Installation:

- Install according to the design drawings to ensure that the spacing and position of the square tubes are accurate.

- Fixed by bolts, welds or fasteners.

- Connection:

- The square pipes can be spliced by connecting pieces (such as corner codes and connecting plates).

- When connecting with other components (such as round pipes, H-shaped steel), special connectors are required.

6: Strengths

- Strong corrosion resistance and long service life.

- High strength, strong carrying capacity.

- Good appearance, with a certain decorative effect.

- Light weight, high strength, easy to transport and install.

- Economical and practical, cost-effective.

7. Market status and development trend

Galvanized square pipe occupies an important position in the construction and manufacturing industry because of its excellent performance and wide application. With the popularity of steel structure buildings and the improvement of environmental protection requirements, the market demand for galvanized square pipes continues to grow. In the future, galvanized square pipe will develop in the direction of higher strength, lighter weight and more environmental protection, at the same time, the application of new galvanized technology and production process will further improve its performance.

Sum up

Galvanized square pipe is an economical and practical steel pipe, which has the advantages of strong corrosion resistance, high strength, good appearance, etc., and is widely used in construction and other fields. With the advancement of technology, the performance and application range of galvanized square pipe will be further improved.
