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 -
What is the difference between C-beam and U-Beam?
First of all, U-beam is a kind of steel material whose cross-section shape is similar to the English letter “U”. It is characterized by high pressure, so it is often used in automobile profile bracket purlin and other occasions that need to withstand greater pressure. I...Read more -
Why spiral pipe is good in oil and gas transportation pipeline?
In the field of oil and gas transportation, spiral pipe shows unique advantages over LSAW pipe, which is mainly attributed to the technical characteristics brought by its special design and production process. First of all, the forming method of spiral pipe makes it poss...Read more -
