对中国热轧H型钢的发展及现状进行了介绍,对涉及到热轧H型钢的的产品标准进行了归类对比分析。随着中国经济发展,中国已经成为热轧H型钢生产大国。在品种上,海洋石油平台、铁略车辆、钢桩、挂车大梁及耐候等热H型钢都得到了广泛应用;在规格上,从100×100～1 000×300等规格都已经批量生产交货。同时,为持续满足中国钢结构设计与发展对热轧H型钢不断提升的要求,对GB/T 11263《热轧H型钢和剖分T型钢》国家标准进行了多次修订。
The development and current situation of hot-rolled H-section steel in China are introduced, and the product standards related to hot-rolled H-section steel are classified and compared. With China’s economic development, China has become a hot-rolled H-beam producer. In terms of varieties, Offshore Oil Platform, TISCO, steel piles, trailers girders and weathering hot H-beam have been widely used; specifications, from 100 × 100 ~ 1 000 × 300 and other specifications have been mass production and delivery . At the same time, in order to continuously meet the requirements of China’s steel structure design and development for the continuous improvement of hot rolled H-beam, GB / T 11263 “hot-rolled H-beam and split T-beam” national standards were revised several times.
