I Beam Steel Product Description I shaped steel is an efficient and economical cutting profile (others include cold-formed thin-walled steel, profiled steel plates, etc.). They can make the steel more efficient and improve its cutting capacity. Different from the ordinary H-shaped steel, the flange of the I-shaped steel is widened, and the inner and outer surfaces are usually parallel, which makes it easy to connect with other components with high-strength bolts. Its size constitutes a reasonable series with complete models, which facilitates engineering design. Shape:  I beam steel features a long, horizontal top flange and a vertical web, connected by a shorter bottom flange. This unique "I" shape provides excellent load-bearing capacity and structural stability, making it widely used in construction and structural engineering applications. Composition:  I beam steel is typically made from carbon steel or low-alloy steel, although other materials such as stainless steel or aluminum may also be used for specialized applications. The choice of material depends on factors such as strength requirements, corrosion resistance, and cost considerations. Manufacturing Process:  I beam steel is produced through a process called hot rolling, where heated steel billets or slabs are passed through rolling mills to form the desired shape. The steel is shaped and stretched under high pressure, resulting in a uniform and precise I-shaped profile. Sizes and Dimensions:  I beam steel is available in a wide range of sizes and dimensions to suit various construction and engineering requirements. Standard sizes are specified by their depth (height of the web) and weight per unit length, such as "W10x22" or "HEA 200". These dimensions indicate the height, width, and weight of the beam.

Wire rod Product Description Ordinary carbon steel hot rolled from the nominal diameter of 5.5-14.0mm, generally rolled into each plate weight in 100-200kg. Now more use of non-torsion high-speed wire rolling mill and control cooling after rolling, The diameter is 5.5-22.0mm and the maximum weight is around 2500kg. Shineyond has many varieties of wire rods. The low carbon steel wire rod in the carbon steel wire rod is commonly known as the soft wire, and the medium and high carbon steel wire rod is commonly known as the hard wire. Wire rods have a wide range of uses. Some wire rods can be used directly after rolling, mainly for reinforcement of reinforced concrete and welding structural parts; some are used as raw materials for reprocessing and used after reprocessing. According to the steel distribution catalogue, wire includes ordinary low carbon steel hot rolled wire rod, welding wire rod, blasting wire rod, tempering thread wire rod, high quality wire rod. Widely used wire is mainly ordinary low carbon steel hot rolled coil, also known as ordinary wire, it is made of Q195, Q215, Q235. Application of Hot Rolled Wire Rod Industrial bar Chrome Bright Sticks for Home, White Goods and Agriculture

Ribbed Steel Bars Product Description The commonly used diameters of ribbed steel bars are 6mm, 8mm, 12mm, and 14mm, and the length is generally 12m. Other sizes can be further customized upon consultation. Ribbed steel bars are small shaped steel products, which are mainly used for the skeleton of steel-energy concrete building components. Ribbed steel bars are usually used in reinforced concrete. The function of their stripes is to increase friction, so that the rebar and concrete bite together and then form one body, which will not twitch under the action of external force. This can improve the strength of concrete. The difference between rebar and plain round steel bars is that the surface will have longitudinal and transverse reinforcements, usually with two longitudinal reinforcements and horizontal reinforcements evenly distributed along the length.
