Steel coil, also known as coil steel. The steel is rolled by hot pressing and cold pressing. In order to facilitate storage and transportation, convenient for all kinds of processing (such as processing into steel plate, steel strip, etc.) forming coil is mainly hot rolled coil and cold rolled coil. Hot rolled coil is the processed product of the billet before recrystallization. Cold rolled coil is the follow-up process of hot rolled coil. The general weight of steel coil is about 15-30T

Carbon structural steel is carbon steel containing less than 0.8% carbon. This steel contains less sulfur, phosphorus and non-metallic inclusions than carbon structural steel, and has better mechanical properties.
Carbon structural steel can be divided into three categories according to the carbon content: low carbon steel (C≤0.25%), medium carbon steel (C is 0.25-0.6%) and high carbon steel (C>0.6%).
Carbon structural steel is divided into two groups with normal manganese content (0.25%-0.8% manganese content) and higher manganese content (0.70%-1.20% manganese content) according to the manganese content. The latter has better mechanical properties. and processing performance

The hot-rolled steel coil is made of continuous casting slab or pre-rolled slab as raw material, heated by a walking heating furnace, descaled by high-pressure water, and then entered into the rough rolling mill. Computer-controlled rolling, after final rolling, laminar cooling (computer-controlled cooling rate) and coiling by a coiler become straight rolls.

Carbon steel plate is a steel with a carbon content of less than 2.11% and without intentional doping of metal elements. The higher the carbon content, the better the hardness and the better the strength. Widely used in machinery manufacturing, building materials, automobile manufacturing, shipbuilding and other fields. It is often used in the manufacture of mechanical parts, bearings, molds, automobile frames, etc.

Pattern steel plate, also known as mesh steel plate, is the surface with diamond shape or protruded steel plate.
The pattern can be a single diamond, lentil or round bean shape, or two or more patterns can be properly combined into a combined pattern board.
The pattern mainly plays the role of anti-slip and decoration. The combined pattern board is better than the single pattern board in terms of anti-skid ability, bending ability, metal saving and appearance.
Pattern steel plate is widely used in shipbuilding, boiler, automobile, tractor, railway carriage and construction industry.
Because of its protruding edge on the surface, the patterned steel plate can be used as floor, workshop escalator, work frame pedal, ship deck, car bottom plate and so on

Carbon steel pipes are divided into hot rolled and cold rolled (drawn) steel pipes.
Hot rolled carbon steel pipe is divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, geological steel pipe and other steel pipe.
Cold rolled (dial) carbon steel pipe in addition to general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, other steel pipe, also includes carbon thin-wall steel pipe, alloy thin-wall steel pipe, stainless steel pipe, special-shaped steel pipe. The outer diameter of hot-rolled seamless pipe is generally greater than 32mm, and the wall thickness is 2.5-75mm. The outer diameter of cold-rolled seamless pipe can be up to 6mm, and the wall thickness can be up to 0.25mm. The outer diameter of thin-walled pipe can be up to 5mm, and the wall thickness is less than 0.25mm
