Medium Thickness Steel Plate

Medium Thickness Steel Plate is a carbon structural steel or low alloy high-strength steel plate with a thickness between 6mm and 60mm, which is widely used in load-bearing structures and high-strength applications. This type of steel plate is mainly produced by hot rolling or controlled rolling and controlled cooling process, involving common steel grades such as A36, SS400, Q235, Q345, S235JR, S355JR, etc.

Excellent strength
Medium Thickness Steel Plate is refined and formed by high-temperature hot continuous rolling and controlled rolling and controlled cooling equipment, especially in high-strength steel grades such as Q345, S355JR, and A572 Grade 50, the tensile strength can reach 450- 630MPa, effectively ensuring the load-bearing requirements and long-term use safety of heavy components.

Stable precision
Through the automatic thickness control (AGC) system and finishing equipment, the thickness error of the Medium Thickness Steel Plate is controlled within ±0.3mm, and the plate surface has high flatness, which meets the requirements of precision manufacturing for material consistency and cutting accuracy.

Strong weldability
Medium-Thickness Steel Plate has been optimized to reduce sulfur and phosphorus content and enhance welding adaptability. Steels such as A36 and Q235 show excellent fusion ability, are suitable for a variety of welding processes, and are widely used in various types of welded structural parts.

Excellent surface
During the production process, the Medium Thickness Steel Plate is treated with efficient descaling and controlled cooling technology, the surface oxide layer is completely removed, and the final roughness is controlled within Ra3.2μm, which is conducive to surface treatment and subsequent coating adhesion.

Carbon steel medium-thickness plates are available in a variety of sizes to suit different needs. Standard dimensions for these plates are:

Thickness: Ranges from 3.0mm to 20mm

Width: Common widths include 1000mm, 1219mm, 1250mm, 1500mm, and 2000mm

Length: Customizable based on requirements, with typical lengths ranging from 2000mm to 6000mm

These plates can be supplied in standard sizes or customized to meet specific project needs.

• A36 Carbon Steel: Due to its good weldability and machinability, A36 is suitable for general-purpose fields such as building structures, steel frames, and pipe supports.
• SS400 Carbon Steel: With excellent tensile strength and structural stability, it is often used in bridge main beams, building skeletons, and engineering support systems, and is suitable for the processing and manufacturing of load-bearing components.
• Q235 Carbon Steel: As a representative of low-carbon steel, Q235 has excellent welding performance and cold forming, and is mainly used for light structures, steel structure accessories, and secondary load-bearing components.
• Q345 Carbon Steel: It is a high-strength structural steel with higher yield strength and tensile properties, suitable for heavy machinery and equipment, pressure-bearing pipelines, and large welded structures.
• S235JR Carbon Steel: It is commonly used in standard building structures, industrial facilities, and machined components, and has good comprehensive mechanical properties and processing adaptability.
• S355JR Carbon Steel: Known for its higher strength, it is suitable for high-load projects such as offshore platforms, steel bridges, and heavy trusses.
• A572 Grade 50 Carbon Steel: As a high-strength low-alloy steel, its excellent welding performance and strength are suitable for bridges, elevated supports, and large steel structures.
• C45 Carbon Steel: A medium-carbon steel type with high hardness and wear resistance. It is often used to manufacture high-wear parts such as gears, shafts, pins, etc. It is one of the key materials in mechanical processing.
