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 -
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 -
Difference between Spiral Steel Pipe and LSAW Steel Pipe
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...Read more -
What is the difference between HEA and HEB?
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 ...Read more -
Difference between galvanized strip pipe and hot-dip galvanized steel pipe
Difference in production process Galvanized strip pipe (pre galvanized steel pipe) is a kind of welded pipe made by welding with galvanized steel strip as raw material. The steel strip itself is coated with a layer of zinc before rolling, and after welding into a pipe, ...Read more -
What are the correct storage methods for galvanized steel strip?
There are two main types of galvanized steel strip, one is cold treated steel strip, the second is heat treated enough steel strip, these two types of steel strip have different characteristics, so the storage method is also different. After hot dip galvanized strip pro...Read more
