Comparison of the advantages and disadvantages of the use of square tube, channel steel, angle steel
Advantages of square tube High compressive strength, good bending strength, high torsional strength, good stability of section size. Welding, connection, easy processing, good plasticity, cold bending, cold rolling performance. Large surface area, less steel per unit su...Read more -
What is the difference between carbon steel and stainless steel?
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...Read more -
What is the difference between galvanized square pipe and ordinary square pipe? Is there a difference in corrosion resistance? Is the scope of use the same?
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...Read more -

Nominal diameter and internal and external diameter of spiral steel pipe
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. Nominal Diameter (DN) Nomi...Read more -
The difference between hot rolled and cold drawn?
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...Read more -
Foreigners build underground shelters with galvanized corrugated pipes and the interior is as luxurious as a hotel!
It has always been a mandatory requirement for the industry to set up air defense shelters in housing construction. For high-rise buildings, a general underground parking lot can be used as a shelter. However, for villas, it is not practical to set up a separate undergro...Read more -
What are the applications of European standard H-section steel HEA, HEB, and HEM?
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...Read more -
Steel Surface Treatment – Hot Dipped Galvanizing Process
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....Read more -
What is SCH (Schedule Number)?
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...Read more -
