--- Why Choose Wuhu Wilma Precision Industry Co., Ltd.? ---
• 19 Years of Industry Experience:
With nearly two decades of expertise in precision steel manufacturing, Wuhu Wilma Precision Industry Co., Ltd. has built a solid reputation across global markets. Our journey began as the Suzhou Wilma Factory, a pioneer in steel grating production, and we have since evolved into a modern, fully integrated manufacturing hub in Wuhu, Anhui. Over the past 19 years, we’ve successfully delivered thousands of projects worldwide—from offshore oil platforms in Southeast Asia to high-end commercial complexes in Europe. One standout case involved a major municipal bridge project in Hangzhou, where our hot-dip galvanized carbon steel grating was used for pedestrian walkways exposed to heavy foot traffic and harsh weather conditions. The grating has performed flawlessly for over 8 years with zero maintenance issues, proving our commitment to long-term reliability. Our deep-rooted knowledge allows us to anticipate engineering challenges, optimize designs for safety and load-bearing capacity, and ensure compliance with international standards such as ISO and EN 14122. This extensive experience translates into smarter solutions, faster delivery times, and unparalleled customer support—making us the preferred partner for clients who demand excellence.
• State-of-the-Art Production Facilities:
Our state-of-the-art facility spans over 70 mu (approximately 46,667 square meters) in the Nanling County Economic and Technological Development Zone, featuring 30,000 square meters of self-built standard workshops. At the core of our production excellence are fully automatic pressure welding lines that utilize pulse arc technology to deliver consistent, high-strength welds with minimal deformation—reducing post-processing time by up to 40% compared to traditional manual methods. For precision cutting, we operate two advanced laser systems: a 20,000-watt laser cutter capable of handling thick steel plates up to 30mm, and a 12,000-watt pipe laser cutter for complex round and square steel profiles. These capabilities were instrumental in a recent project for a large-scale wastewater treatment plant in Guangdong Province, where we fabricated custom non-standard hole pattern grating designed to prevent clogging while maintaining structural integrity under continuous wet conditions. The entire batch was completed within 15 days, thanks to our automated workflow and real-time quality monitoring systems. Additionally, our CNC machining centers ensure tolerances within ±0.05mm for precision components, enabling seamless integration into complex mechanical systems. Our smart factory infrastructure not only enhances productivity but also supports sustainable manufacturing through energy-efficient processes and reduced material waste—proving that innovation and sustainability go hand in hand at Wuhu Wilma.
--- Our Diverse Product Offerings ---
• High-Quality Steel Grating Solutions:
Wuhu Wilma Precision Industry Co., Ltd. offers four main series of steel grating tailored to diverse industrial and architectural needs. Our flagship product—the Hot-Dip Galvanized Carbon Steel Grating (Standard Series)—is made from Q235/Q355 carbon steel, available in flat steel thicknesses of 3mm, 4mm, and 5mm, with crossbar spacing options ranging from 30mm to 100mm. This series has been widely adopted in refineries, ports, and shopping malls due to its modular design, ease of installation, and 15+ year service life. A notable example is the Shanghai Metro Expansion Project, where we supplied over 2,500 square meters of this grating for elevated station platforms. The grating’s anti-slip surface and corrosion resistance have ensured safe, reliable access even in humid underground environments. We also specialize in Ball-Jointed Railings with powder-coated finishes in RAL color codes, which were used in a luxury residential development in Shenzhen. These railings not only met strict aesthetic requirements but also passed rigorous impact and fatigue tests. Furthermore, our Precision Steel Components—including step plates, brackets, and custom fittings—are machined using CNC technology to achieve tight tolerances, making them ideal for use in machinery, elevators, and industrial equipment. Each product undergoes strict quality control, including ultrasonic testing and load simulation, ensuring every piece meets or exceeds client expectations.
--- Customization Options to Meet Your Needs ---
• Tailored Steel Grating Sizes and Designs:
At Wuhu Wilma, we understand that no two projects are alike. That’s why we offer full customization across size, shape, hole pattern, finish, and load capacity. Whether you need a 1m x 1m standard panel or a 3m x 6m custom panel for an offshore platform, our team works closely with engineers to deliver precise specifications. For instance, in a recent project for a chemical plant in Tianjin, we developed a grating panel with a unique elliptical hole pattern to allow for efficient drainage while preventing small tools from falling through—a critical safety requirement. We also provide non-standard hole patterns for sewage treatment plants, such as those used in a municipal project in Chengdu, where our grating prevented blockages caused by sludge buildup. Our design team uses CAD software to simulate stress distribution and optimize performance before production. Clients can choose from various finishes including hot-dip galvanizing, powder coating (RAL colors), and stainless steel plating. We also offer modular assembly systems that reduce on-site labor and installation time. This level of flexibility ensures that every solution fits perfectly—not just functionally, but aesthetically and economically.
• Flexible Solutions for Unique Projects:
We pride ourselves on solving complex engineering challenges through innovative design and agile manufacturing. A prime example is our collaboration with a high-rise architectural firm in Dubai on a skybridge project connecting two skyscrapers. The challenge? Designing a lightweight yet ultra-strong grating that could withstand extreme wind loads and maintain visual elegance. Our team engineered a hybrid grating system combining 4mm flat steel with reinforced ball-jointed connections and a brushed stainless steel finish. The result was a 12-meter-long panel weighing only 45kg/m² but capable of supporting 1,000kg/m²—far exceeding local safety codes. Another case involved a renewable energy plant in Inner Mongolia, where we produced grating panels with embedded solar sensor mounts, allowing for easy integration without additional hardware. These projects highlight our ability to adapt beyond standard offerings and deliver turnkey solutions. With a dedicated R&D team and rapid prototyping capabilities, we can respond to urgent requests within 72 hours. Whether it’s a one-off prototype or a bulk order, Wuhu Wilma delivers precision, speed, and reliability—making us the go-to partner for clients pushing the boundaries of design and functionality.
--- Commitment to Quality and Sustainability ---
• Durable Materials and Long-Lasting Products:
Quality is not just a promise—it’s a process at Wuhu Wilma Precision Industry Co., Ltd. Every product begins with premium raw materials sourced from certified suppliers, including Q235 and Q355 carbon steel, and 304/316 stainless steel for high-corrosion environments. Our hot-dip galvanizing process follows ISO 1461 standards, ensuring a uniform zinc coating thickness of 80–120μm, which provides excellent protection against rust and wear. In a long-term study conducted by a third-party lab in Zhejiang, samples from our galvanized grating showed no signs of degradation after 12 years of simulated marine exposure—well beyond the industry average. This durability is further enhanced by our advanced welding techniques, which minimize heat distortion and ensure consistent joint strength. We also conduct regular tensile, bending, and impact tests on every batch, with results documented and available upon request. Sustainability is equally important: our production line recycles over 95% of metal scraps, and our energy-efficient lasers reduce power consumption by 30% compared to older models. By combining robust materials, rigorous testing, and eco-conscious practices, we deliver products that last longer, cost less over time, and align with green building certifications like LEED and BREEAM—making Wuhu Wilma a responsible choice for forward-thinking clients worldwide.
