In alignment with the United Nations Sustainable Development Goals (SDGs) for 2030, industries worldwide are increasingly shifting toward materials and technologies that offer long-term value while reducing environmental impact. One of the most effective steps we’ve taken in this direction is the adoption of polyester resin powder coating—a proven method for enhancing the performance and sustainability of steel pipes.
Through this innovation, we have developed two robust product lines: Color-Coated Pipes and Powder-Coated Steel Pipes. These pipes are designed not only to deliver superior mechanical performance and corrosion resistance but also to minimize the need for frequent replacements, thus contributing to responsible resource consumption.

Understanding Powder Coating and Its Industrial Importance
Powder coating is a dry finishing process that involves applying fine polyester resin powder to metal surfaces, followed by curing under controlled heat. This forms a continuous protective film that is mechanically tough, aesthetically appealing, and highly resistant to corrosion, UV exposure, and weathering.
Unlike traditional liquid painting, powder coating is free from solvents and volatile organic compounds (VOCs), making it an environmentally safer and more durable solution. Since its introduction in the 1960s, it has gained global popularity for its longevity and consistent finish—especially in applications where metal is exposed to harsh environmental conditions.
Our Powder-Coating Product Solutions
We offer two categories of powder-coating pipes to address various performance and cost requirements:
Color-Coated Pipes
These pipes are manufactured using galvanized steel and coated with polyester resin on both inner and outer surfaces. The dual-layer coating provides maximum protection against corrosion, making them particularly suitable for humid and highly corrosive environments such as agricultural greenhouses and coastal infrastructure.
Additionally, their smooth, colorful finish enhances aesthetic value while supporting long-term structural integrity.
2. Powder-Coated Steel Pipes
This product line features galvanized steel coated only on the external surface. While more economical, it still offers significant protection against external corrosion, particularly from moisture and atmospheric contaminants. The inner galvanized layer ensures resistance to mild corrosive agents when used to transport air or liquid, making them suitable for various pipeline systems.
Key Advantages and Characteristics
Corrosion Resistance
One of the most notable advantages of powder-coated steel pipes is their ability to resist rust and degradation over time.
Color-Coated Pipes provide up to 10 times the lifespan of traditional galvanized pipes thanks to their dual-surface coating.
Powder Coated Pipes extend service life by approximately threefold, ensuring longer intervals between maintenance or replacements.
High Bendability
Our powder-coated products are engineered to retain flexibility during fabrication. They can be bent or shaped—whether in 90° angles or complex 3D curves—without cracking or delamination. This makes them ideal for applications where custom or angular configurations are needed.
Aesthetic and Surface Quality
Cured under high temperatures, the powder-coated surface results in a smooth, uniform, and glossy finish. These pipes are available in multiple colors, allowing customization for functional or branding purposes. The finish not only adds visual appeal but also reinforces the surface against scratches and minor impact damage.
Key Applications Across Industries
Greenhouse Construction
High humidity levels and temperature fluctuations can rapidly degrade untreated or lightly treated steel. Color-coated pipes are extensively used as winding shafts, support frames, and structural members in greenhouses due to their corrosion resistance and durability under constant moisture exposure.
Coastal Installations
Salt-laden air in coastal regions is one of the most aggressive agents of corrosion. Powder-coated pipes are an excellent solution for coastal fencing, vessel handrails, and marine walkways, where aesthetics and long service life are essential.
Pipelines for Water and Liquid in Corrosive Environment
In agriculture, pipelines are routinely exposed to sunlight, moisture, and varying temperatures. Our powder-coated pipes provide excellent protection in such conditions. They are also designed for weldability and leak resistance, with ongoing developments underway to introduce pressure-resistant connectors to complement pipeline applications.
Furniture and Industrial Racking
For both residential and industrial environments, powder-coated pipes offer an attractive, corrosion-resistant solution for furniture frames, warehouse racking, and modular systems. Their surface is non-conductive, enhancing safety in environments where accidental electrical contact may occur. They are also lightweight, easy to assemble, and cost-efficient.
Conclusion: A Step Toward Greener Manufacturing
By significantly extending the lifespan of steel components, powder coating reduces the need for frequent replacements and lowers overall raw material consumption. The process also eliminates many of the harmful environmental side effects of traditional painting methods.
In practical terms, this means fewer resources extracted from the earth, less steel processed, and less waste in the environment. Choosing powder-coated pipes is not only a business decision, but also a responsible step toward sustainable industrial practices.
Our powder-coated pipe offerings are available in round, square, and rectangular shapes, with custom dimensions and colors available upon request. Whether you’re building a greenhouse, installing a coastal fence, or developing a new modular furniture line, we’re here to provide solutions that meet both performance and sustainability standards.
