Marine and shipyard plate bending equipment
EZHONG ship plate bending machines and heavy plate rolls support shipyard curved plate and over-wide forming for hull-related structures.
Industry challenges
Shipyards need equipment that handles wide curved plates, arc sections, and stiff workpieces without losing surface quality or operator safety under heavy loads.
Forming process steps
Define plate width, thickness, curvature, and whether rolling or progressive bending is required.
Select marine-oriented three-roll machines with backup rolls for wide plates.
Form arc/curve sections; verify geometry against templates or measurements.
Integrate with cutting, welding, and block assembly workflows.
Recommended EZHONG equipment
Primary: Ship Plate Bending Machine. Supporting options: CNC 3-roll plate bending and plate levelers such as W43T for flatness before forming.
Typical parameter ranges
Published ship models include full-load minimum radii around R600–R650 mm with multi-row backup rollers and dual main motors (for example 30–75 kW × 2 depending on model class).

What makes a ship plate bending machine different?
Marine machines often emphasize wide-plate stiffness via backup rollers, dual lower-roll drive, and structures designed for arc plates rather than only closed cylinders.
Can standard plate rolls serve shipyards?
Some jobs can, but over-wide curved plates usually benefit from marine-oriented backup-roll designs. Share max width and curvature for a proper match.
Do you support export shipyard projects?
Yes. EZHONG exports heavy forming equipment and can discuss FAT, packing, and installation support for overseas yards via Contact.

Published models associated with this application context.
4 Rolls Plate Bending Machine
EZHONG CNC four-roll plate bending machines pre-bend plate ends and roll cylinders or cones in fewer steps. Published models cover roughly 20–120 mm thickness and 2000–4200 mm useful length, with spherical roller bearings on each work roll.
Ship Plate Bending Machine
EZHONG ship plate bending machines are marine three-roll systems for bow arc plates, hatch structures, and over-wide curved ship workpieces. Multi-set backup rollers stiffen the lower rolls for wide plate control.
W43T Leveling Machine
EZHONG W43T plate levelers straighten medium and heavy steel plate with patented sub-roller drive and CNC pressing calculation. Published examples include 40×3000 mm and 80×3000 mm models, plus a large EZW43T-120×3000 mm (400 MPa) reference unit.
W43B Leveling Machine
EZHONG W43B plate levelers use a six-upper and seven-lower straightening roll layout with spring-loaded feed rolls and fine-tuned middle rolls. Example published model EZW43B-10×3000 levels about 10 mm plate at 3000 mm width.
W43C Leveling Machine
EZHONG W43C roller levellers fully drive upper and lower main rolls with dual motors, soft start, and emergency braking. Multi-row support rolls and mill-type needle bearings help correct wave and scoop deformation on thin to medium plate.
