According to the use can be divided into carbon structural steel, carbon tool steel.Shandong Zhongao Steel Co. LTD. is a large-scale iron and steel enterprise integrating sintering, iron making, steel making, rolling, pickling, coating and plating, tube making, power generation, oxygen production, cement and port. The main products include sheet (hot rolled coil, cold formed coil, open and longitudinal cut sizing board, pickling board, galvanized sheet), section steel, bar, wire, welded pipe, etc. The by-products include cement, steel slag powder, water slag powder, etc. Among them, fine plate accounted for more than 70% of the total steel production.1. Low carbon steel: Carbon content from 0.10% to 0.30% Low carbon steel is easy to accept a variety of processing such as forging, welding and cutting, often used in the manufacture of chains, rivets, bolts, shafts, etc. 2. High carbon steel: Often called tool steel, carbon content from 0.60% to 1.70%, can be hardened and tempered. Hammers and crowbars are made of steel with carbon content of 0.75%; Cutting tools such as drills, taps and reamers are manufactured from steel with carbon content of 0.90% to 1.00%. 3. Medium carbon steel: In the medium strength level of various uses, medium carbon steel is the most widely used, in addition to as a building material, but also a large number of mechanical parts.1.2 layer PE foil protection. 2. After binding and making, cover with polyethylene waterproof cloth. 3. Thick wood covering. 4. LCL metal pallet to avoid damage, wooden pallet full load. 5. According to customer requirements.
