H型钢
Is a more optimal allocation of cross-sectional area, strong emphasis is more reasonable than the economic section of high profile, cross section and its letters "H" the same as the name. H bending beam with strong, simple construction, cost and structural advantages of light weight, has been widely be.
Hot-rolled H section steel of that method:
H is divided into wide-flange steel H beam (HK), narrow flange H beam (HZ) and H section steel pile (HU) categories.
The said methods are: height H width B flange thickness web thickness t1 t2, such as the H section steel Q235, SS400 200200812 expressed as high 200mm wide and 200mm web thickness 8mm, 12mm flange thickness of wide-flange H beam, the grade for the Q235 or SS400.
The advantages of hot-rolled H section steel:
H section steel is a new kind of economic construction steel. H beam cross section form a reasonable, good mechanical properties, rolling cross-section extends over all the points on the uniform, internal stress, compared with the ordinary I-beam with a section modulus, light weight, saving advantages of metal, will enable the Building structure to reduce 30-40%; has its inner and outer parallel legs, leg-side is the right angles to form component assembly can save welding, riveting work amounted to 25%. Commonly used in the required commitment cut capacity, good stability, a large section of building (such as factories, high-rise buildings, etc.), as well as bridges, ships, lifting and transportation machinery, equipment foundation, frame, foundation piles.
H section steel is mainly used for industrial plants, civil construction, municipal works, oil platforms, bridges, flatbed beams, electrified railway power bracket, steel railway bridges and other light, ultra-light H steel is ideal for containers, mobile homes, various garage, box-type trains, electrical support, various venues, cottage industry.
Hot-rolled H section steel for different purposes according to a rational allocation of the section size of the high aspect ratio, excellent mechanical properties and superior performance.
