Medium Thicknedd Steel Plate

Available Grades

A36

Universal medium-thick carbon plate with stable tensile performance and outstanding weldability. It is the primary choice for factory building frames, equipment brackets and general heavy mechanical structures under normal temperature.

S235JR

European standard mild medium plate with guaranteed room-temperature impact resistance. Suitable for steel structure engineering, container frames and non-critical load-bearing components of engineering vehicles.

S355JR

Low-alloy high-strength medium thick plate with higher yield strength than S235 series. It reduces structural weight while ensuring bearing capacity, popular for crane arms and workshop support beams.

A516 Gr 70

Boiler & pressure vessel dedicated medium carbon plate with excellent high-temperature toughness. Mainly applied for low-medium pressure storage tanks, heat exchanger shells and boiler auxiliary parts.

SS400

JIS standard multi-purpose medium thick plate with balanced cost and mechanical property. Commonly processed into chassis, base frames and metal structural parts for general industrial equipment.

Product Features

• Moderate thickness brings high structural stiffness, resisting bending deformation under heavy static and dynamic loads.
• Broad grade coverage including carbon steel and low alloy steel, matching different load and temperature working conditions.
• Great comprehensive processability, compatible with flame cutting, plasma cutting, bending and all mainstream welding methods.
• Strict rolling thickness tolerance, flat surface with minimal warpage, lowering secondary machining loss.
• Stable batch chemical & mechanical consistency, each batch attached with complete mill test report.
• Meets international mainstream industrial standards, supporting third-party inspection for global engineering projects.

Applications

• Steel Structure ConstructionManufacture factory main beams, column supports, floor bearing plates and high-rise auxiliary structural frames for industrial plants and warehouses.
• Heavy Machinery ManufacturingProduce excavator chassis, crane supporting arms, equipment bases and gear box shells bearing long-term heavy impact loads.
• Ship & Offshore Auxiliary PartsFabricate ship deck supports, barge hull plates and offshore platform secondary structures with moderate seawater corrosion resistance.
• Pressure Vessel & Storage TankMedium thick vessel-grade plates make low-pressure oil, water and chemical storage tanks, as well as heat exchanger shells.
• Transport & Bridge EngineeringUsed for bridge secondary girders, truck carriage frames and container bottom bearing panels requiring stable load capacity.

Product Advantages

• Balanced cost and strength: Cheaper than alloy thick plates while meeting most heavy-load structural demands to cut procurement cost.
• Strong design flexibility: Multiple thickness & grade options help customers optimize structural thickness and lower overall equipment weight.
• One-stop processing service: Custom cutting, surface blasting and flattening reduce extra outsourcing processing fees.
• Reliable long service life: Uniform internal grain structure improves fatigue resistance, lowering equipment maintenance & replacement frequency.
• Flexible supply mode: Abundant stock of standard sizes for fast delivery; custom rolling for special thickness bulk orders.
