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 -
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 -
EHONG STEEL –SEAMLESS STEEL PIPE
Seamless steel pipes are circular, square, or rectangular steel materials with a hollow cross-section and no seams around the periphery. Seamless steel pipes are made from steel ingots or solid pipe billets through piercing to form rough pipes, whic...Read more -
EHONG STEEL –HOT DIP GALVANIZED STEEL PIPE
Hot dip galvanized pipe are produced by reacting molten metal with the iron substrate to form an alloy layer, thereby bonding the substrate and the coating together. Hot-dip galvanizing involves first acid-washing the steel pipe to remove surface rust...Read more -
