【Core point of view】In May, the actual output of special steel bars was 3.145 million tons, an increase of 156,000 tons compared with April; the planned production volume of steel mills in June was 3.178 million tons, an increase of 33,000 tons compared with May.1. In May, the actual production of e

In 2021, the output of crude steel in the iron and steel industry will be high and then low, and the cumulative reduction will be year-on-year. In the first half of 2021, iron ore prices continued to soar, and then oscillated and fell in the second half. In 2021, the price of steel will fluctuate up

Galvanized coil is produced by continuous hot-dip galvanizing process using hot-rolled steel strip or cold-rolled steel strip as substrate. Hot-dip galvanized sheets are supplied in rectangular flat sheets after cross-cutting; hot-dip galvanized coils are supplied in coils after coiling. Hot-dip gal

There are four forms of h-beam specifications.
1. According to the width of the product flange, it is divided into wide flange, middle flange and narrow flange H-beam. The flange width b of the wide flange and middle flange H-section steel is greater than or equal to the web height H, and the flange width b of the narrow flange H-section steel is about half of the web height H.
2. According to the use of the product, it can be divided into H-shaped steel beam, H-shaped steel column, H-shaped steel pile, H-shaped steel flange extra-thick beam. Sometimes parallel leg channels and parallel flange T-beams are also included in the scope of H-beams. Beam materials generally use narrow flange H-beams, and column materials generally use wide-flange H-beams.
3. According to the production method, it can be divided into welded H-beam and rolled H-beam.
4. According to the specifications and sizes, it is divided into large, medium and small H-beams. Generally speaking, products with web hei

Production MethodsEdit BroadcastH-beam steel can be produced by welding or rolling. Welded H-beam is to cut strip of suitable thickness to suitable width, and weld the flange and web together on a continuous welding unit. Welded H-beam has the disadvantages of large metal consumption, difficult to e
