Struggling to Roll Thick Hull Plates? Plagued by Poor Fit-Up and Welding Rework?
The shipbuilding industry demands massive scale and millimeter precision. You're facing pressure to process thicker, tougher marine-grade steel while fighting bottlenecks from undersized machinery and inconsistent quality. As a specialist manufacturer and direct factory partner, WEIYA delivers complete shipbuilding fabrication solutions. We don't just sell machines; we engineer integrated, heavy-duty lines for rolling, cutting, and bending the massive components you need to build faster and stronger.
Are These Shipyard Fabrication Hurdles Slowing You Down?
We understand the specific, heavy-duty challenges shipyards face. Our solutions are engineered to solve them.
Inability to Form Thick Plate (20mm-60mm+)
Your existing rollers and presses lack the power to handle the thick, high-strength marine-grade plates required for hulls and structural bulkheads, forcing you to outsource or rely on slow, outdated methods.
Poor Fit-Up & Excessive Rework
Inaccurate cuts from plasma or imprecise rolling lead to massive fit-up gaps between hull sections. This wastes thousands of man-hours in grinding, gouging, and excessive welding, destroying your project timeline.
Bottlenecks from Large Components
You are forced to weld smaller, 6-meter sections together because your press brake or shear can't handle 12-meter-long deck stiffeners. This creates weak points, adds labor, and slows down your entire assembly process.
Stop Guessing. Start Engineering Your Heavy Fabrication Line
In shipbuilding, an underpowered machine is a critical failure. Our process is designed to eliminate this risk. We engineer your heavy-duty solution before you buy.
We Analyze Your Core Problem
Our engineers start by analyzing your specific application—the material (e.g., DH36/EH36 plate), the thicknesses, the required curvature, and the scale of your components.
We Engineer Your Custom Solution
We prevent integration chaos. We select and integrate the right heavy-duty machines—such as a 4-roll plate roller paired with a tandem press brake—to create a seamless, powerful, and efficient fabrication line. We Deliver a Turnkey Solution
We manage the delivery, on-site installation, and training. You get a fully operational solution optimized for your parts and a single point of accountability: our factory.

Our Solutions for Your Shipbuilding Application
As a specialized manufacturer of heavy-duty machinery, we provide solutions engineered for the specific components you build.
Hull Section Rolling
Heavy-Duty, High-Accuracy Plate Rolling
Case Study: Engineering a 4-roll solution for a shipyard fabricating LNG carrier hulls.
We engineer our 4-roll plate rolling machines for maximum power and precision. As a direct manufacturer, we have full control over the roll forging (42CrMo steel) and frame fabrication (heavy, annealed), ensuring every machine provides the massive torque and rigidity needed to roll thick marine plates perfectly.
The Challenge:
The client was rolling 40mm thick, high-strength plate for LNG hulls. Their old 3-roll machine was underpowered, required multiple passes, and left a large, unusable flat end, wasting expensive material and causing poor fit-up.
The Challenge:
Our engineers specified and delivered a heavy-duty W12 4-Roll Hydraulic Plate Rolling Machine. Its powerful hydraulics and superior 4-roll geometry allowed the client to pre-bend and roll the 40mm plate to the perfect curvature in a single pass. This eliminated the flat end, saved material, and cut rolling time by 60%.
Deck Stiffeners & Long Components
Large-Format Synchronized Tandem Bending
Case Study: Delivering a 12-meter tandem press brake solution for deck panel stiffeners.
We are a specialist supplier of large-scale tandem press brakes. We have full control over the CNC synchronization, ensuring both machines work as one, delivering perfect angle consistency over the entire length.
The Challenge:
A shipyard needed to form 12-meter-long deck stiffeners. Their only option was bending 6-meter sections and welding them, which was slow, labor-intensive, and created a weaker, non-compliant joint in the middle.
The Challenge:
We engineered and delivered a 2 x 600 Ton x 6000mm tandem press brake solution. The Delem CNC system perfectly synchronizes the two rams, allowing their operators to easily and accurately bend the full 12-meter stiffeners as a single piece, improving structural integrity and cutting production time by half.
Large Plate Cutting & Processing
High-Power, Large-Format Laser Cutting
Case Study: Replacing a shipyard's slow plasma cutters with a high-definition fiber laser.
We build our gantry fiber lasers for large-scale industrial cutting. As a factory, we can customize gantry widths (e.g., 4m or 6m) and integrate high-power 20kW+ sources, ensuring you get the speed and precision plasma cannot match.
The Challenge:
The client was using two gantry plasma cutters to process all their plate. The process was slow, created significant heat distortion on thinner plates, and left a beveled, dross-filled edge that required hundreds of hours of grinding before welding.
The Challenge:
We delivered a 20kW large-format (4m x 12m) gantry fiber laser solution. The laser cuts 3x faster than their old plasma, produces a perfectly clean, square edge with zero dross, and eliminates heat distortion. This allowed them to move parts directly from cutting to welding, saving thousands in labor.
Bulkheads & Structural Frames
Heavy Tonnage Forming & Straightening
Case Study: A 2000-ton hydraulic press for forming and straightening heavy bulkheads.
We manufacture our H-frame hydraulic presses for extreme-duty applications. We have full control over our factory's fabrication and annealing process, ensuring the frame can withstand full tonnage, 24/7, for forming and straightening the thickest structural parts.
The Challenge:
A ship repair yard needed to form and straighten thick (50mm+) structural frames and bulkheads that had warped during welding. Their existing presses were underpowered and lacked the bed size.
The Challenge:
Our factory engineered a custom 2000-ton H-frame hydraulic press with a 4m x 3m bed. The machine's massive, rigid frame and controllable hydraulic power allowed the client to both form new, thick components and easily straighten warped sections, making it a critical, versatile tool in their repair operations.
How Our Factory Control Delivers a Better Shipbuilding Solution
As a dedicated shipbuilding solutions factory and manufacturer, our direct control over manufacturing allows us to perfect the details that guarantee your solution can handle the scale.

Your Questions About Our Shipbuilding Solution Capabilities, Answered.
Answers to common questions about our solution-focused approach.
What is the thickest plate your rolling machines can handle?
This is our specialty. As a manufacturer, we can engineer our heavy-duty plate rollers to handle 40mm, 60mm, 80mm, or even thicker plates, depending on your specific application and material width.
Can you provide a press brake longer than 6 meters?
Yes. We are experts in synchronized tandem press brake solutions. We can link two or more machines to create a single, synchronized bending line of 12, 18 meters, or more.
How do you install and service such large machines globally?
We have extensive experience. Our qualified factory engineers travel to your shipyard for on-site installation, commissioning, and comprehensive operator training to ensure your massive equipment is running perfectly.
Are you a direct factory or a trading company?
We are a direct manufacturer. Since 1989, we have been producing all our machinery in our own 5,000 m² facility. This control is essential for delivering reliable, integrated solutions.
Is your fiber laser better than plasma for cutting thick plate?
For most applications, yes. A high-power (20kW+) fiber laser cuts faster, produces a perfectly square, dross-free edge, and eliminates heat distortion, saving you thousands of hours in secondary grinding and rework.
What is the warranty on a complete solution?
We stand behind our quality as a supplier and manufacturer with a comprehensive warranty, including a two-year warranty on core components for all machines included in your solution package
