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.

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.

Steel Pipe Product Description As an important part of steel products, steel pipes are divided into two categories: seamless steel pipes and welded steel pipes due to their different manufacturing processes and shapes of the tube blanks used. Seamless steel pipe Because of their different manufacturing processes, they are divided into two types: hot-rolled (extruded) seamless steel pipes and cold-rolled seamless steel pipes. Welded steel pipe The blanks used in welded steel pipes are steel plates or strips. Due to their different welding processes, they are divided into furnace welded pipes, electric welded (resistance welded) pipes and automatic arc welded pipes. Because of their different welding forms, they are divided into two types: straight seam welded pipes and spiral welded pipes. Because of their end shapes, they are divided into round welded pipes and special-shaped (square, flat, etc.) welded pipes.
