--- High-Quality Galvanized Steel Pipes ---

• Durability and Corrosion Resistance:

At Anyang Zhongxin Pipe Industry Co., Ltd., we pride ourselves on delivering galvanized steel pipes that stand the test of time. Our products are manufactured using high-frequency welding technology from cold-rolled galvanized strip steel, ensuring superior structural integrity and long-term performance. The galvanizing process forms a dense zinc crystal layer that acts as a robust barrier against moisture, chemicals, and environmental exposure—critical for applications in harsh climates. This sacrificial protection mechanism ensures that even if the surface is scratched or damaged, the exposed steel remains protected by the zinc’s electrochemical reaction. A real-world example of this durability comes from a large-scale solar power project in Yunnan Province, where our 40x60mm galvanized square tubes were used in rooftop mounting brackets. Despite being exposed to monsoon rains and intense UV radiation for over three years, no signs of rust or degradation were reported during routine inspections. The client praised our pipes for their exceptional corrosion resistance, which significantly reduced maintenance costs and extended system lifespan. Additionally, our pipes have been rigorously tested under accelerated corrosion testing (ASTM B117), achieving over 1,000 hours without visible red rust—far exceeding industry standards. These results reflect our unwavering focus on quality control, certified by our AAA-Class Integrity Management Unit status and Level 3 Work Safety Standardization certification. When you choose Zhongxin, you’re choosing proven reliability backed by data and real-world success.

• Applications Across Various Industries:

Our galvanized steel pipes are engineered for versatility, serving a broad spectrum of industries across China and beyond. From infrastructure to renewable energy, our products have become a trusted component in critical projects nationwide. One standout case involves a major airport expansion in Hubei Province, where our 100x100mm galvanized rectangular tubes were selected for the structural framework of terminal walkways and baggage handling systems. The project required materials with high load-bearing capacity, dimensional accuracy, and resistance to fluctuating weather conditions—conditions perfectly met by our precision-welded, zinc-coated pipes. The construction team reported seamless integration into the design, thanks to consistent thickness tolerance (±0.1mm) and straightness within 1.5mm per meter. Another notable example is a steel structure farm in Shanxi Province, where our 38x38mm square tubes were used to build greenhouse supports. The galvanized finish ensured longevity in humid, saline-rich soil environments, preventing premature failure. In the machinery sector, a leading agricultural equipment manufacturer in Anhui chose our 25x25mm tubes for tractor chassis components due to their excellent weldability and tensile strength. These real-world implementations demonstrate how Zhongxin’s galvanized pipes deliver consistent performance across sectors—from construction and transportation to agriculture and clean energy. With an annual production capacity of 100,000 tons and a national sales network, we’ve earned trust through tangible results, proving that our products don’t just meet specifications—they exceed expectations.

--- Comprehensive Product Range ---

• Specifications and Sizes Available:

Anyang Zhongxin Pipe Industry Co., Ltd. offers one of the most comprehensive ranges of galvanized steel pipes in China, catering to both standard and specialized requirements. Our product line includes galvanized square tubes (20x20mm to 100x100mm), rectangular tubes (20x40mm to 48x98mm), and round pipes ranging from 1/2 inch to 3 inches in diameter, all available in thicknesses from 0.8mm to 2.0mm. Each specification is produced under strict quality control, ensuring dimensional accuracy, uniform coating thickness (minimum 6μm), and consistent mechanical properties. For instance, our 37x77mm rectangular tube has been widely adopted in steel frame construction for multi-story buildings, offering a balance of strength and weight efficiency. Similarly, our 1-inch round galvanized pipe (32mm OD) is a preferred choice for plumbing and HVAC systems due to its smooth inner surface and resistance to internal corrosion. We maintain a dedicated inventory of over 200 SKUs, allowing for rapid order fulfillment and minimizing lead times. Our advanced CNC cutting and bending machines ensure precise customization, while our automated inspection systems verify every batch before shipment. Customers from Guangdong to Shaanxi have consistently reported high satisfaction with our product consistency and availability. Whether you need small quantities for prototyping or bulk orders for large infrastructure projects, Zhongxin delivers scalable solutions without compromising on quality. Our ability to supply such a wide variety of sizes and shapes stems from our vertically integrated manufacturing setup, covering raw material procurement, rolling, welding, galvanizing, and packaging—all under one roof in Neihuang County, Henan. This vertical integration not only ensures cost efficiency but also enables faster response to market demands and custom requests.

• Custom Solutions for Unique Needs:

Beyond standard offerings, Anyang Zhongxin Pipe Industry Co., Ltd. excels in providing tailor-made solutions for clients with unique engineering challenges. We understand that no two projects are identical, and our R&D and technical teams work closely with customers to develop customized pipe profiles, coatings, and finishing options. A prime example is a custom-designed 50x70mm galvanized rectangular tube developed for a shipbuilding company in Shandong. The client required a pipe with enhanced fatigue resistance and anti-slip surface texture for deck railings. After extensive testing, we modified our galvanizing process to include a micro-textured zinc layer and adjusted the welding parameters to reduce stress concentration points. The result was a pipe that passed rigorous maritime vibration tests and received positive feedback from naval engineers. Another case involved a solar panel installer in Guizhou who needed lightweight yet strong support beams for mountainous installations. We engineered a 38x38mm square tube with a hollow core and optimized wall thickness (1.2mm), reducing weight by 18% while maintaining structural integrity. This innovation helped lower transportation costs and simplified on-site assembly. Our flexible production line allows for quick changeovers between different sizes and configurations, enabling us to handle small batches of custom orders efficiently. We also offer cut-to-length services, laser marking, and packaging customization to match brand or project-specific requirements. With a track record of successful collaborations with over 300 enterprises nationwide, Zhongxin continues to push the boundaries of what’s possible in steel pipe manufacturing—proving that innovation, flexibility, and quality go hand in hand.
