Wide Width 2000mm Hot Rolled Carbon Steel Coil Q235B Q345B Heavy Duty 2-25mm Shipbuilding Storage Tanks

The wide width hot rolled carbon steel coil with widths up to 2000mm is engineered for heavy industry applications that demand large-format blanks with minimum welding and maximum material utilization. Shipbuilding panels, storage tank shells, heavy machinery bases and large structural components benefit directly from wide coils because they reduce the number of longitudinal welds required, improving both structural integrity and fabrication productivity. Zhengde supplies these coils in Q235B general structural grade and Q345B high strength grade, covering thicknesses from 2mm to 25mm with coil weights up to 30 tons. The wide strip is produced with advanced width and crown control to maintain consistent profile across the full width, which is critical for subsequent plate flattening, laser cutting and edge preparation processes. Surface quality is monitored online to ensure freedom from laminations, scabs and edge defects that would be costly to discover after cutting. Each coil is supplied with mill test certificates and can be leveled, cut-to-length or slit to project-specific dimensions as a value-added service, reducing the customer's inventory and processing burden.

• Maximum Material Utilization: Wide 2000mm format reduces weld seams and off-cut waste in large panel fabrication
• Heavy Coil Weights: Up to 30 tons per coil supports continuous production runs and fewer coil changes
• Dual Grade Availability: Q235B and Q345B cover both general structural and high strength design requirements
• Stable Width Profile: Advanced crown control ensures consistent thickness across the full strip width
• Defect Free Surface: Online inspection detects laminations and edge defects before they reach the cutting table
• Value Added Processing: Leveling, cut-to-length and slitting services reduce customer inventory and handling cost

Wide hot rolled coils are used in ship hull plates, deck structures, storage tank shells and roofs, large diameter pipe, heavy machinery frames, bridge girders, pressure vessels and structural fabrication where large format blanks reduce welding and improve productivity.

Wide coils are secured with heavy-duty steel straps, edge protectors and waterproof wrapping for ocean transport. Mill certificates, SGS/BV inspection and value-added processing are available. Delivery 7-15 days for stock, 20-30 days for production.
