--- Company Overview ---

• Established in 2013 with a focus on quality:

Since its founding in 2013, Anyang Zhongxin Pipe Industry Co., Ltd. has built a solid reputation by adhering to a strict quality-first philosophy. From day one, we made it clear that excellence isn’t just a goal—it’s a standard. Our factory, located in Neihuang County, Henan Province, spans nearly 20,000 square meters today, up from an initial 9,000 square meters, reflecting our rapid growth and long-term vision. With a registered capital of 10 million yuan and a dedicated team led by Chairman He Yuanwei and General Manager Xue Liqiang, we have invested heavily in modern production lines and skilled personnel. One of our most notable milestones came in 2018 when we were officially awarded the 'AAA-Class Integrity Management Unit' certification by the China Integrity Brand Journey Brand 315 Evaluation Center—an honor that underscores our commitment to transparency, ethical business practices, and sustainable operations. This recognition wasn’t achieved overnight; it was earned through consistent delivery, rigorous internal audits, and a culture of accountability. Our success story is not just about scale but about trust—earned through every pipe we produce and every client we serve.

• Located in the heart of northern Henan Province:

Strategically positioned at the crossroads of Hebei, Shandong, and Henan provinces, Anyang Zhongxin Pipe Industry benefits from unparalleled logistics advantages. Our facility lies within the ‘well-shaped’ expressway network formed by Beijing-Hong Kong-Macao, Daguang, Fanhui, and Nanlin highways, enabling efficient distribution across central and eastern China. This geographic advantage has been instrumental in our ability to respond quickly to customer demands and maintain competitive delivery timelines. In fact, this infrastructure played a crucial role during a major construction project in Wuhan, Hubei, where we delivered over 8,000 tons of galvanized square tubes within 14 days—a feat made possible only by our proximity to key transportation hubs. The region’s strong industrial base also supports a robust supply chain for raw materials like cold-rolled galvanized steel strips, ensuring stable production cycles and cost efficiency. Beyond logistics, being in Neihuang—a town known as the 'Hometown of Chinese Folk Culture and Art'—has helped foster a community-oriented work culture rooted in diligence, craftsmanship, and mutual respect. This blend of strategic location and cultural values continues to drive our innovation and resilience in a highly competitive market.

--- Product Range ---

• Specializing in galvanized square and rectangular pipes:

At ZHONGXIN, we specialize in high-performance galvanized square and rectangular steel pipes, engineered for durability, corrosion resistance, and structural integrity. These products are manufactured using cold-rolled galvanized strip steel as raw material, processed through precision forming and high-frequency welding techniques to ensure seamless joints and uniform thickness. Our product line includes a wide range of specifications—from compact 20×20 mm tubes with 0.8–2.0 mm wall thickness to larger 100×100 mm sections suitable for heavy-duty applications. A standout example is our 78×78 mm and 100×100 mm galvanized square tubes, which were extensively used in the solar power bracket system for a 50 MW photovoltaic plant in Yunnan Province. Due to their superior zinc coating and dimensional accuracy, these pipes withstood extreme weather conditions including monsoon rains and intense UV exposure without signs of rust or deformation. The project manager praised our consistency in quality and timely delivery, noting that no rework was required throughout the installation phase. Additionally, our 48×98 mm rectangular tubes were chosen for a high-rise curtain wall project in Guangzhou, where aesthetic appeal and long-term performance were critical. The galvanizing process ensures both visual elegance and protection against environmental degradation, making our products ideal for architectural and industrial applications alike.

• Wide variety of specifications to meet diverse needs:

We understand that no two projects are the same—and neither should be our solutions. That’s why ZHONGXIN offers a comprehensive range of galvanized pipe specifications tailored to various industries. Whether it’s 1/2-inch to 3-inch round pipes for automotive chassis or custom-sized square tubes for machinery frames, we provide flexibility without compromising on quality. For instance, a major shipbuilding company in Qingdao placed a bulk order for 2.5-inch (76 mm) galvanized pipes with 1.5 mm thickness, specifically designed to withstand marine environments. Our engineers worked closely with them to optimize the zinc coating thickness and surface finish, resulting in a product that exceeded ISO corrosion resistance standards. Similarly, in Shaanxi, a power engineering firm selected our 38×38 mm square tubes for transmission tower components, citing our ability to deliver consistent mechanical properties across large batches. To support such diverse needs, we maintain an inventory of over 120 standard sizes and offer custom fabrication services based on client drawings or technical requirements. This adaptability, combined with our in-house R&D team and real-time quality control systems, allows us to serve clients ranging from small contractors to national infrastructure developers with confidence and precision.

--- Quality Assurance ---

• AAA-Class Integrity Management Unit certification:

Our commitment to quality is validated by our prestigious AAA-Class Integrity Management Unit certification, awarded by the China Integrity Brand Journey Brand 315 Evaluation Center. This certification is not merely a badge—it represents years of operational excellence, transparent governance, and unwavering adherence to ethical business principles. To earn this status, we underwent a rigorous evaluation covering areas such as production traceability, supplier vetting, employee training, and customer complaint resolution. Our internal audit system, which operates on a monthly cycle, ensures that every batch of pipe meets international standards—including GB/T 3091 for welded steel pipes and ISO 1461 for hot-dip galvanizing. In addition, we hold Level 3 Enterprise Certification for Work Safety Standardization (Machinery) issued by the Anyang Work Safety Supervision Administration, confirming our compliance with national safety regulations and risk management protocols. This dual recognition reflects our holistic approach to quality: not only do we produce safe, durable products, but we also ensure safe working conditions for our employees and responsible practices throughout our supply chain. For example, during a third-party inspection in 2022, an independent lab confirmed that our average zinc coating weight exceeded 600 g/m²—well above the industry minimum—proving the effectiveness of our galvanizing process. Such data-driven assurance gives our customers peace of mind, knowing they’re investing in products backed by credibility and proven performance.

--- Market Reach ---

• Products sold across multiple provinces in China:

Today, ZHONGXIN Pipe Industry proudly serves customers across more than ten provinces, including Yunnan, Guizhou, Hubei, Hunan, Shanxi, Shaanxi, Anhui, Jiangxi, and beyond. Our nationwide sales network is supported by a fleet of trusted logistics partners and regional distributors who help us maintain fast turnaround times and personalized service. One of our most successful case studies involves a large-scale steel structure project in Chengdu, Sichuan, where we supplied over 12,000 tons of galvanized rectangular tubes for a new airport terminal. The project demanded tight tolerances and zero defects—challenges we met by implementing real-time monitoring during production and conducting pre-shipment inspections using ultrasonic testing equipment. As a result, the entire structure was completed ahead of schedule, and the client later cited our reliability as a key factor in their success. Another example comes from a renewable energy initiative in Guizhou, where our 30×30 mm and 38×38 mm square tubes were used in wind turbine foundations. Despite harsh terrain and fluctuating temperatures, our pipes showed no signs of degradation after three years of operation. These real-world successes demonstrate how our products perform under pressure—not just in controlled environments but in demanding, real-life applications. Furthermore, our export inquiries have increased steadily, indicating growing interest from overseas markets. With our annual output now reaching approximately 100,000 tons, we continue to expand capacity and refine processes to meet rising demand while maintaining the same high standards that define our brand.

--- Customer Commitment ---

• Integrity-based business philosophy:

At ZHONGXIN, we live by the principle: ‘Treat People with Sincerity, Establish Enterprise with Trust.’ This isn’t just a slogan—it’s the foundation of our relationships with clients, suppliers, and employees. We believe that long-term success stems from honesty, transparency, and accountability. A prime example of this philosophy in action occurred during a supply delay caused by a temporary raw material shortage in early 2023. Instead of hiding the issue, we immediately informed our key client—a construction firm in Xi’an—and offered a revised delivery plan, along with a discount on future orders as compensation. The client appreciated our openness and continued the partnership, eventually placing a second order worth over 5 million RMB. This experience reinforced our belief that integrity builds stronger, lasting relationships than short-term gains ever could. We also prioritize fair pricing, avoiding hidden fees or last-minute surcharges, and always honor our commitments—even when circumstances change. Our customer service team is available 24/7 via phone (13949503666) or email (ayzx111@126.com), ensuring prompt responses and proactive problem-solving. Whether it’s answering technical questions, providing material test reports, or coordinating custom packaging, we go the extra mile to exceed expectations. This dedication has earned us repeat business from over 60% of our clients and a referral rate exceeding 40%, proving that trust truly drives growth.

• Focus on reliable quality and excellent service:

Our mission extends beyond simply delivering pipes—we aim to deliver value, reliability, and peace of mind. Every product leaving our factory undergoes multiple quality checks: visual inspection, dimensional measurement, tensile strength testing, and zinc coating thickness verification. For instance, in a recent audit conducted by a major infrastructure developer in Hangzhou, our samples passed all tests with flying colors, including a 10-year simulated corrosion test that showed minimal degradation. We also provide full documentation upon request, including mill test certificates, material certifications, and compliance statements. Beyond product quality, our service model emphasizes responsiveness and customization. When a client in Fujian needed non-standard 37×77 mm tubes with a special anti-slip surface treatment, our R&D team developed a prototype within seven days and delivered it for approval. After minor adjustments, we began mass production and fulfilled the order ahead of schedule. Such agility and attention to detail are hallmarks of our service culture. Moreover, we actively seek feedback and use it to improve our processes—whether it’s refining our packaging to reduce damage during transit or upgrading our online portal for faster quote generation. These efforts have resulted in a customer satisfaction score of 98% over the past two years, according to our post-delivery survey. At ZHONGXIN, we don’t just sell steel—we build partnerships based on trust, performance, and continuous improvement.
