The first step in metal processing is cutting, which involves simply severing raw materials or separating them into shapes to obtain rough blanks. Common metal cutting methods include: grinding wheel cutting, saw cutting, flame cutting, plasma cutting, laser cutting, a...
In different weather climate steel corrugated culvert construction precautions are not the same, winter and summer, high temperature and low temperature, the environment is different construction measures are also different.

Welding, connection, easy processing, good plasticity, cold bending, cold rolling performance.
Large surface area, less steel per unit su...
Carbon steel, also known as carbon steel, refers to iron and carbon alloys containing less than 2% carbon, carbon steel in addition to carbon generally contains a small amount of silicon, manganese, sulfur and phosphorus.
Stainless steel, also known as stainless acid-res...
There are mainly the following differences between galvanized square tubes and ordinary square tubes:
**Corrosion resistance**:
- Galvanized square pipe has good corrosion resistance. Through galvanized treatment, a layer of zinc is formed on the surface of the square tu...
Spiral steel pipe is a kind of steel pipe made by rolling a steel strip into a pipe shape at a certain spiral angle (forming angle) and then welding it. It is widely used in pipeline systems for oil, natural gas and water transmission.

The difference between Hot Rolled Steel Pipe and Cold Drawn Steel Pipes 1:
In the production of cold rolled pipe, its cross-section can have a certain degree of bending, bending is conducive to the bearing capacity of cold rolled pipe. In the production of hot-rolled tu...
The H series of European standard H section steel primarily includes various models such as HEA, HEB, and HEM, each with multiple specifications to meet the needs of different engineering projects. Specifically:
HEA: This is a narrow-flange H-section steel with smaller c...
Hot Dipped Galvanizing Process is a process of coating a metal surface with a layer of zinc to prevent corrosion. This process is particularly suitable for steel and iron materials, as it effectively extends the life of the material and improves its corrosion resistance....
SCH stands for “Schedule,” which is a numbering system used in the American Standard Pipe System to indicate wall thickness. It is used in conjunction with nominal diameter (NPS) to provide standardized wall thickness options for pipes of different sizes, facilitating de...
Spiral Steel Pipe and LSAW Steel Pipe are two common types of welded steel pipe, and there are some differences in their manufacturing process, structural characteristics, performance and application.
Manufacturing process
1. SSAW pipe:
It is made by rolling strip stee...
The HEA series is characterized by narrow flanges and a high cross-section, offering excellent bending performance. Taking Hea 200 Beam as an example, it has a height of 200mm, a flange width of 100mm, a web thickness of 5.5mm, a flange thickness of 8.5mm, and a section ...
