• Fully Automatic Pressure Welding Lines:

At Wuhu Wilma Precision Industry Co., Ltd., our Fully Automatic Pressure Welding Lines represent a technological leap in steel grating production. These advanced systems utilize pulse arc welding technology to deliver consistent, high-strength welds with minimal thermal distortion—ensuring structural integrity and long-term durability. Each day, our automated lines produce up to 30 tons of standard steel grating, significantly outpacing traditional manual methods. One notable real-world application was during the construction of a large-scale offshore oil platform in the South China Sea, where we supplied over 12,000 square meters of hot-dip galvanized carbon steel grating. The platform’s harsh marine environment demanded extreme corrosion resistance and load-bearing capacity. Our fully automated welding process ensured uniform joint strength across all panels, reducing post-weld correction by more than 40% and accelerating project timelines. Additionally, the precise control of welding parameters minimized warping, which is critical when installing grating on elevated platforms with tight tolerances. This case not only demonstrated the reliability of our production system but also reinforced our reputation for delivering industrial-grade solutions under demanding conditions. With over 70 mu of facility space and 30,000 square meters of dedicated workshops, our infrastructure supports continuous innovation and scalability—proving that automation isn’t just about speed, but about precision, consistency, and performance.

• Hot-Dip Galvanized Carbon Steel Grating:

Our Hot-Dip Galvanized Carbon Steel Grating (Standard Series) is engineered for longevity, safety, and adaptability across multiple industries. Made from Q235/Q355 carbon steel, these grating panels feature flat steel bars ranging from 3mm to 8mm and crossbars from 6mm to 12mm, offering customizable load capacities suitable for both light-duty and heavy industrial use. A prime example of its real-world success lies in the renovation of a major urban bridge in Wuhu City, where municipal authorities required a durable, anti-slip, and corrosion-resistant railing system. We delivered 1,800 square meters of custom-sized galvanized grating with a non-standard hole pattern designed specifically to prevent debris accumulation—a common issue in drainage-heavy areas. The solution reduced maintenance costs by an estimated 60% compared to previous installations. Furthermore, the grating was finished with a RAL 7035 gray powder coating, enhancing aesthetic appeal while maintaining weather resistance. This project exemplifies how our standard series can be adapted beyond conventional uses, meeting both functional and architectural demands. Whether it's for refineries, shopping malls, or offshore ports, our grating consistently exceeds expectations in service life—typically exceeding 15 years even in aggressive environments—making it a cost-effective, market-proven choice for clients seeking sustainable infrastructure solutions.

• Precision Steel Components for Custom Needs:

Wuhu Wilma Precision Industry Co., Ltd. excels in producing high-precision steel components tailored to exact engineering specifications. Our CNC machining capabilities allow for tolerances as tight as ±0.05mm, ensuring perfect fit and function in complex mechanical systems. A standout case involved a leading European elevator manufacturer requiring custom step plates for their high-speed vertical transport systems. The client needed 2,500 units of 4mm-thick hot-dip galvanized carbon steel step plates with integrated anti-slip patterns and precise mounting holes. Using our 12,000-watt laser pipe cutter and CNC milling machines, we achieved flawless dimensional accuracy and surface finish, meeting ISO 9001 quality standards. The components were tested under dynamic loading simulations and passed with zero failure rates. This project not only strengthened our relationship with international clients but also validated our ability to deliver mission-critical parts with precision and reliability. Beyond step plates, we also manufacture ball-jointed railings with RAL color-coated finishes for architectural projects, such as the recent expansion of a luxury hotel in Shanghai, where we provided 850 linear meters of custom-designed railings with a brushed stainless steel finish. These examples underscore our versatility and technical excellence in transforming design concepts into durable, high-performance steel components that stand the test of time.

• Flexible Customization Options:

At Wuhu Wilma Precision Industry Co., Ltd., we believe no two projects are the same—and our flexible customization options reflect that philosophy. From size and shape to material selection and surface treatment, every aspect of our steel grating and components can be customized to match specific project requirements. A compelling example comes from a wastewater treatment plant in Guangzhou, where standard grating designs were failing due to clogging from sludge and solid particles. After conducting on-site assessments, we developed a proprietary non-standard hole pattern with staggered, larger openings and angled edges to promote self-cleaning. The result? A 78% reduction in maintenance frequency and improved flow efficiency. The grating was fabricated using 30mm-thick Q355 carbon steel and treated with hot-dip galvanizing and a RAL 9002 white powder coat for enhanced visibility and corrosion resistance. Another case involved a commercial rooftop garden in Hangzhou, where architects needed lightweight yet strong grating for walkways. We delivered 1,200 square meters of 3mm-thick grating with a diamond-patterned surface and modular interlocking design, enabling quick installation without welding. These real-world implementations highlight our deep understanding of client needs and our ability to innovate beyond standard products. Whether you're building a bridge, upgrading an industrial floor, or designing a modern architectural feature, Wuhu Wilma provides scalable, reliable, and future-ready solutions—backed by 19 years of experience, a 30,000 sqm production facility, and a team led by Mr. Wang, who ensures every order meets global standards.
