Steel H-beam is an economical cross-section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. Each part of the H-shaped steel is arranged at right angles, which has the advantages of strong bending resistance in all directions, simple construction, cost saving, and light structure weight.

Cold-rolled sheet is a product made of hot-rolled coil as raw material and rolled at room temperature below the recrystallization temperature. It is mostly used in automobile manufacturing and electrical products. Cold rolling is rolling at the recrystallization temperature, but it is generally understood as rolling using normal temperature rolling materials.

Cold-rolled coil (annealed state): It is obtained by bell-type annealing of chilled coil before coiling. After annealing, its work hardening phenomenon and internal stress are eliminated (greatly reduced), that is, the yield strength is reduced to approach that of cold-rolled coil.

Hot rolled, that is, hot-rolled coils, which use slabs (mainly continuous casting slabs) as raw materials, and after heating, they are made into strip steel by rough rolling units and finishing rolling units.

Cold rolling: with hot rolled steel coil as raw material, after pickling to remove the oxide skin for cold continuous rolling, the finished product is rolled hard roll, because of the cold hardening caused by continuous cold deformation of the rolled hard roll strength, hardness, toughness and plastic index decline, so the stamping performance will deteriorate, can only be used for simple deformation parts. Hard roll can be used as raw material in hot dip galvanizing plant because hot dip galvanizing units are equipped with annealing line. Rolled hard coil weight is generally 6~13.5 tons, steel coil at room temperature, hot rolled pickling coil continuous rolling. The inner diameter is 610mm.

Cold rolling is made of hot rolled plate coil as raw material, rolled at normal temperature under the recrystallization temperature, cold rolled steel plate is produced by cold rolling process, referred to as cold plate. The thickness of cold-rolled plate is generally between 0.1 and 8.0mm, and the thickness of cold-rolled plate produced by most factories is below 4.5mm. The thickness and width of cold-rolled plate are determined by the equipment capacity of each factory and the market demand.

Continuous casting slab or preliminary rolling slab is used as raw material, heated by stepping furnace, descaled by high pressure water into roughing mill, roughing mill through cutting head, tail, and then into finishing mill, the implementation of computer controlled rolling, after the final rolling is laminar cooling (computer controlled cooling rate) and coiler winding, straight coil.Namely: hot rolled steel plate, flat hot rolled steel coil, slitting and other products. Hot rolled finishing roll is formed by pickling and oiling after removing oxidation skin.

It's a flat sheet of steel poured with molten steel, cooled and pressed.
It is flat, rectangular and can be rolled directly or cut from a wide strip of steel.
Steel plate is divided by thickness, thin steel plate < 4 mm (the thinest 0.2 mm), medium thick steel plate 4~60 mm, extra thick steel plate 60~115 mm.
Steel plate is divided into hot rolled and cold rolled according to rolling.

3pe anti-corrosion steel pipe base material includes seamless steel pipe, spiral steel pipe and straight seam steel pipe. The three-layer polyethylene (3PE) anticorrosive coating has been widely used in the oil pipeline industry for its good corrosion resistance, water permeability resistance and mechanical properties.3PE anticorrosive steel pipe refers to 3-layer structure polyolefin coating (MAPEC) external anticorrosive steel pipe, there are IPN8710, FBE epoxy powder, epoxy coal asphalt and other anticorrosive methods.3PE anticorrosive steel pipe has many uses, which is suitable for underground coal mine water supply and drainage, underground grouting, positive and negative pressure ventilation, gas extraction, fire sprinkler pipe network. Thermal power plant process water waste slag, backwater pipeline. It has excellent applicability to the water supply pipeline of spray prevention and sprinkler system. Electric power, communication, highway cable protection sleeve.

Carbon steel tubes are made of ingot or solid round steel that is perforated into wool tubes and then hot rolled, cold rolled or cold drawn. Carbon steel pipe plays an important role in our steel pipe industry.General carbon steel pipe: is made of 10, 20, 30, 35, 45 and other high-quality carbon junction steel 16Mn, 5MnV and other low alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel hot rolled or cold rolled. 10, 20 low carbon steel manufacturing seamless pipe is mainly used for fluid conveying pipe. 45, 40Cr and other medium carbon steel seamless pipe to manufacture mechanical parts, such as cars, tractor parts. Generally use carbon steel pipe to ensure the strength and flattening test. Delivery of hot-rolled steel pipes in hot-rolled or heat-treated condition; Cold rolled and delivered in heat-treated condition.

Seamless steel pipe has hollow section, widely used for conveying fluid pipeline, such as conveying oil, natural gas, gas, water and some solid materials, etc. Compared with solid steel such as round steel, steel pipe has the same bending and torsional strength and lighter weight. It is a kind of economic section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction.
