Wide flange, middle flange and narrow flange steel H Beam For Multiple Function Usage

H beam product specifications are many, classification methods have the following several. (1) According to the flange width of the product, it can be divided into wide flange, middle flange and narrow flange H-shaped steel. Flange width B of wide flange and middle flange H-beams is greater than or equal to web height H. The flange width B of narrow flange H beam is about one half of web height H. (2) According to the use of the product, it is divided into H type steel beam, H type steel column, H type steel pile, extremely thick flange H type steel beam. Parallel leg channels and parallel flanges are sometimes included in the range of H-beams. In general, narrow flange H steel as beam, with wide flange H steel as column, and thus known as beam H steel and column H steel. (3) According to the production mode, it is divided into welded H-beam and rolled H-beam. (4) According to the size specification size is divided into large, medium and small H-shaped steel. Usually the web height H in 700mm above the product is called large, 300 ~ 700mm is called medium, less than 300mm is called small. By the end of 1990, the world's largest H-section web height of 1200mm, flange width of 530mm.

Internationally, the product standard of H-beam is divided into British system and metric system. The United States, Britain and other countries use the British system, China, Japan, Germany and Russia and other countries use the metric system, although the units of measurement used in the British system and the metric system are different, but the H-beam is mostly used to express their specifications with four dimensions, namely: web height H, flange width B, web thickness D and flange thickness T. Although all countries in the world to the size of h-beam size specification size of the expression method is different. But the size range and size tolerance of the products produced are not much different
