Product function:Due to the above advantages, H-shaped steel is widely used, mainly for various civil and industrial building structures; Various large-span industrial factories and modern high-rise buildings, especially in areas with frequent seismic activity and under high-temperature working conditions; Large bridges with high load-bearing capacity, good cross-sectional stability, and large spans are required; Heavy equipment; Expressway; Ship skeleton; Mine support; Foundation treatment and embankment engineering; Various machine components.
Production process:Internationally, the product standards for H-beams are divided into two categories:English system and metric system. Countries such as the United States and the United Kingdom use the British system, while countries such as China, Japan, Germany, and Russia use the metric system. Although the units of measurement used in the British and metric systems are different, H-beams are mostly represented by four dimensions:web height=100% h, flange width=100% b, web thickness d, and flange thickness t. Although countries around the world have different ways of expressing the size specifications of H-beams. But the range of size specifications and dimensional tolerances of the products produced are not significantly different.

1、 H-beam name:
H-shaped steel is an economical section steel with better mechanical properties developed from the optimization of I-shaped steel, especially named after the same section as the English letter ' H ' .
2、 H-beam representation method:
Height H × Width B × Web thickness t1 × Wing plate thickness t2
3、 Perfect advantages of H-shaped steel:
H-shaped steel can be processed into T-shaped steel, and honeycomb beams can be combined to form various cross-sectional forms, greatly meeting the needs of engineering design and production
Wide flange, high lateral stiffness, and strong bending resistance
The two surfaces of the flange are parallel to each other, making it easy to connect, process, and install
Compared with welded I-beams, it has low cost, high accuracy, low residual stress, no need for expensive welding materials and weld seam testing, and can save about 30% of steel structure production costs
Under the same cross-sectional load, the weight of hot-rolled H-steel structure is reduced by 15% -20% compared to traditional tung structure.
Compared with concrete structures, hot-rolled H-steel structures can increase their usage area by 6%, while reducing their self weight by 20-30%, reducing the internal force of structural design.
