1. The scope of utilization of H-shaped steel: 

① Prefabricated beam and column components in industrial and civil construction steel structures;  

② Steel structure load support frame of industrial buildings; 

③ Steel pile and anchor supporting structure of underground building; 

④petrochemical equipment and power engineering and other industrial machinery and equipment structure;

⑤ large span steel bridge prefabricated components; 

⑥ ships, machinery and equipment manufacturing frame shear walls; 

⑦ Train, car, tractor beam support frame; 

⑧ Port conveyor belt, highway block support frame.

2. the use of cold-rolled H-beam technology fairness: the use of H-beam steel in industrial and civil construction not only saves power energy and landing costs than common I-beam steel, but also can drop the steel content. If the steel structure of industrial plants uses hot tie steel and hot tie wide flange H-shape steel, the steel content is relatively high, which can drop 15%-20%.

Third, the product development orientation of H-shaped steel: Laiwu Steel development design and development of fire protection, weather resistance, seismic grade series of products for the construction of H-shaped steel, international development standards H-shaped steel, high toughness controlled rolling and cooling H-shaped steel and other types; The development and design of light shaped H-shaped steel with thick wall, different width and thickness; Develop and design weather-resistant H-shaped steel for railway vehicles, H-shaped steel for tower mast construction of power transformation projects, H-shaped steel for mainland service platforms and other commodities. Promote the current product taste of H-beam steel.
