Rebar

Rebar is a type of steel used in both reinforced concrete and pre-stressed concrete, with a circular cross-section and sometimes a square with rounded corners. It includes round bar, ribbed bar, and torsion bar. The steel bar for reinforced concrete refers to the straight bar or the wire bar for reinforced concrete. Its shape is divided into two kinds: plain bar and deformed bar. The plain steel bar is actually small round steel and the circular steel of ordinary low-carbon steel. Deformed bars are surface ribbed bars, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length. The transverse ribs are spiral, herringbone, and crescent. Expressed in millimeters of nominal diameter. The nominal diameter of deformed bars is equivalent to the nominal diameter of plain bars with equal cross sections. The nominal diameter of the reinforcing bar is 8-50 mm. The recommended diameter is 8, 12, 16, 20, 25, 32, 40 mm. Steel grades: 20MnSi, 20MnV, 25MnSi, BS 20MnSi. The steel bar mainly bears the tensile stress in the concrete. Because of the action of the rib, the deformed steel bar has a greater bond ability with the concrete, so it can bear the action of the external force better. Steel bars are widely used in all kinds of building structures. In particular, large, heavy, light thin-walled, and high-rise building structures.

The steel bar has good formability, weldability, and easy processing, which can meet the needs of the automobile industry for complex structural components. In addition, the steel rod has high strength, good wear resistance, and strong corrosion resistance, which also makes it play an important role in automobile manufacturing. Since the properties of cold and hot rods are basically the same, the factors that affect the formability will depend on the difference in the surface quality. Since the surface quality is better from the cold rods, it is generally said that steel rods of the same material, the cold rod forms better than the hot rod.

302 stainless steel ball belongs to austenitic-type steel, which is close to 304, but the hardness of 302 is higher (HRC ≤28), which has good rust and corrosion resistance.

Square Steel

Square steel is solid bar. A hollow tube, as distinguished from a square tube, belongs to a pipe. Steel (Steel) is the ingot, billet, or steel by pressure processing required by the various shapes, sizes, and properties of the material. Steel is an essential material for national construction and the realization of the four modernizations. It is widely used and has many varieties. According to the shape of the section, steel is generally divided into four categories: profiles, plates, tubes, and metal products. To facilitate the organization of steel production, order supply, and good management work, it is divided into heavy rail, light rail, large section steel, medium section steel, small section steel, steel cold-bending section, high-quality section steel, wire rod, medium thickness steel plate, thin steel plate, electrical silicon steel sheet, strip steel, seamless steel pipe, welded steel pipe, metal products, and other varieties.

Flat Steel

Flat steel refers to steel with a width of 12-300mm, a thickness of 4-60mm, a rectangular cross-section, and slightly blunt edges. Flat steel can be finished steel and can also be used as blanks for welded pipes and thin slabs for stacked thin plates. As a finished product, flat steel can be used to make hoop iron, tools, and mechanical parts. It can also be used as structural parts of house frames and escalators in construction.

Flat steel is rolled with negative deviation, but it is delivered according to the actual weight, and the utilization rate is 1 to 5 percentage points higher than that of steel plates. Flat steel can be produced in a fixed thickness, fixed width, and fixed length according to user needs, which reduces cutting for users, saves processes, reduces labor and material consumption, and also reduces processing loss of raw materials, saving time, labor, and energy. The products have been professionally used in steel structure manufacturing, machinery manufacturing, automobile industry, mining machinery, hoisting machinery, and other industrial materials.

Angle Steel

Angle steel, commonly known as angle iron, is a long strip of steel whose two sides are perpendicular to each other to form an angle. Angle steel can be divided into equilateral angle steel and unequal angle steel. Angle steel can be composed of various stress components according to different needs of the structure, and can also be used as a connector between components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouse shelves.

Angle steel is mainly used as the skeleton or connectors of various machinery and devices in the field of agricultural machinery. The common connection methods for fixing other components on the angle steel are welding and bolts. The two side widths of equilateral angle steel are equal, and its specification is expressed in millimeters of side width × side width × side thickness, such as “∠30×30×3”. It can also be indicated by the model number, which is the centimeter of the side width, such as ∠3#. The model does not indicate the size of different side thicknesses in the same model, so fill in the side width and side thickness dimensions of the angle steel in the contract and other documents, and avoid using a separate model to express. The specifications of hot-rolled equilateral angle steel are 2#-20#.

Angle steel can be composed of various stress components according to different structures, and can also be used as a connector between components. It is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, bus bar support installation, and warehouse shelves, etc. Angle steel is carbon structural steel for construction. It is a simple section steel, mainly used for metal components and workshop frames, etc. In use, it is required to have better weldability, plastic deformation performance, and certain mechanical strength. The raw material billet for the production of angle steel is low carbon square billet, and the finished angle steel is delivered in the state of hot rolling, normalizing, or hot rolling.
