摘　　要：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 state of hot-rolled H-beams of China is introduced and product standards involving HR H-beams are classified, compared and analyzed. With the development of national economy, China has become a major producer of HR H-beam steel in the world. In terms of product varieties, H-beams for offshore drilling platforms, railway cars, steel piles, trailer frames and weathering-resistance applications have been widely used. In terms of specifications, products in the range of 100＊100-1000＊300 have been batch produced and delivered to customers. At the same time, several revisions have been made to the national standard GB/T11263 Hot-rolled H-beams and Subdivided T-beams, to meet the ever-rising requirements on H-beam products by domestic steel structure sector.
