What's the difference between hot rolled H steel and welded H? Is it the same weight?
Specifications (section size) a wide range. Height, web, flange thickness, flange width can be selected according to customer requirements of steel plate welding. It can be used as a standard except for hot-rolled H steel.
Stable performance and good internal organization. Due to continuous casting from smelting to rolling, steel production than hot-rolled H steel process requirements, equipment capacity, control level, detection means is high, so the welding of H steel internal organization, chemical composition, various properties (mechanical properties, process performance indicators are reliable and stable etc.).
The product has high precision and good surface quality. Because of the high precision and good surface quality of the steel plate, the accuracy of the H after welding is high and the surface quality is good. (used for welding H steel plate) the thickness deviation is generally a few hundredths of a millimeter to zero a few millimeters, and the thickness deviation of hot rolled H steel is a few tenths of mm to 1 mm, is nearly 10 times.
Select various grades of steel. Hot rolled H steel is mainly Q235B and Q345B, which requires small batch of special steel, the production plant can not be produced. Welding can be made according to the requirements of the steel plate.
