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 –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 -
