Product Introduction
ZAM Rectangular Steel Pipe is a new generation of high-performance corrosion-resistant structural pipe, professionally manufactured by Wuxi Chengxingchuang Metal Products Co., Ltd. It is widely used in photovoltaic brackets, construction engineering, and machinery manufacturing, among other fields. With its excellent corrosion resistance and mechanical properties, it has become an ideal upgrade and replacement for traditional galvanized pipes.
ZAM Rectangular Steel Pipe uses high-quality low-carbon steel as its base material, and a zinc-aluminum-magnesium ternary alloy coating is formed on the surface through a hot-dip galvanizing process. This combination of high-strength structural performance and long-term corrosion resistance gives it a more robust coating and stronger self-healing ability compared to ordinary galvanized pipes. It maintains stable performance in harsh environments, making it the preferred structural material for outdoor high-weather-resistance applications.

Product Advantages
Superior Corrosion Resistance
The ternary alloy coating forms a stable passivation film, providing 23 times the salt spray resistance of ordinary hot-dip galvanized pipes, making it suitable for coastal, high-humidity, and industrial corrosive environments.
Self-Healing Capability
Cuts or scratches automatically form protective corrosion products, slowing down rust spread.
High Cost-Effectiveness
Longer service life, lower maintenance frequency, and overall cost-effectiveness compared to stainless steel and heavy-duty galvanized products.
Easy Processing
Excellent welding, punching, and bending performance, compatible with automated production lines, resulting in higher installation efficiency.
Environmentally Friendly
The coating contains no harmful substances and complies with EU RoHS environmental standards.
Product Applications
Photovoltaic Support Systems
Ground/roof photovoltaic supports, weather-resistant and corrosion-resistant, supporting stable operation of photovoltaic modules for over 25 years.
Building Engineering
Steel structure workshops, curtain wall frames, enclosure structures, lightweight and high-strength.
Municipal Transportation
Guardrails, bus shelters, streetlight poles, outstanding resistance to outdoor corrosion.
Machinery Manufacturing
