1. Construction machinery series: concrete pump trucks, truck cranes, truck-mounted cranes, crawler cranes, excavators, rotary drilling rigs, down-the-hole drilling rigs, forklifts, crushers, shield machines, mining vehicles, mixer trucks, drag pumps, Loaders, graders, road rollers, etc.
2. Port machinery series: fixed cranes, floating cranes, bridge cranes, door cranes, belt conveyors, etc.
3. Automobile modified vehicles: semi-trailer, dump truck, garbage disposal vehicle, etc. T610, T700, T800, HG60, HG70 and other products are used for the beam, wing plate and double plate of the semi-trailer, and weathering steel is also used.
4. Electric power towers: Electric power towers are mainly embodied as corner towers and steel pipe towers, and Q420B and GR65 are mainly used.
5. General machinery: Blower products use a lot of high-strength steel, the main grades are Q390B steel plate, Q460C steel plate, DB685 steel plate, HG785 steel plate, NM360 steel plate, which are mainly used in impellers and air outlets.
6. Coal machinery series: Coal shearers, coal loaders, and hydraulic supports mainly use wear-resistant plates, high-strength steel 460C steel plates, Q550D steel plates, and Q690D steel plates, as well as NM360 steel plates and NM400 steel plates.
7. Wind power installation: Large wind power equipment adopts high-strength steel above Q390 steel plate.
8.Ocean engineering equipment has begun to use high-strength steel in batches, including Q390B steel plate grade and high-grade HG785D steel plate, mainly medium and thick plates, and Q345D steel plate is often used.
