A curated selection of our most versatile galvanized steel pipe systems, trusted across construction, infrastructure, and industrial applications worldwide.
2-inch 3.0mm Galvanized Round Pipe
This 2-inch x 3.0mm thick galvanized steel strip pipe is a robust choice for high-load applications. The 3.0mm wall thickness gives it excellent load-bearing capacity and resistance to deformation, allowing it to withstand pressure stably even in high-stress environments such as building frames and heavy equipment supports. The uniform bright silver galvanized coating provides long-lasting rust protection in humid outdoor and corrosive industrial environments, eliminating the need for frequent maintenance.
80mm × 2.5mm Galvanized Square Tube
This 80mm square & 2.5mm thick galvanized steel tube, with its robust performance and meticulous craftsmanship, is the preferred material for medium to heavy-duty applications. The 80mm square cross-section combined with 2.5mm thick walls maximizes structural stability and load-bearing capacity, making it suitable for medium to heavy-duty applications such as building frames, heavy-duty shelving columns, and large greenhouse main frames, exhibiting outstanding resistance to deformation. The surface undergoes a fine galvanizing treatment, resulting in a uniform and dense zinc layer with a smooth texture, offering not only excellent aesthetics but also strong resistance to outdoor moisture and industrial corrosion, providing long-lasting rust prevention and maintenance-free operation. Precision cutting technology ensures clean, burr-free cuts, eliminating the need for secondary grinding during installation and significantly improving construction efficiency. The high uniformity of the tubes allows for tight fit and secure, convenient transportation and bundling, while also keeping costs under control for bulk applications. Whether it's municipal engineering railings, industrial warehouse shelves, main supports for agricultural greenhouses, or large frames for commercial displays, it has become a reliable choice that balances practicality and aesthetics with its 'strong load-bearing capacity, high durability, and high aesthetic appeal,' making it suitable for various medium and heavy-duty structural scenarios.
50×100 Galvanized Rectangular Tube
This 50x100 galvanized rectangular tube, with its golden ratio cross-section and superior craftsmanship, is the preferred choice for medium-load structural applications. The 50x100 flat rectangular design offers outstanding bending and torsional resistance, providing 20% higher stiffness than round tubes at the same weight. It is suitable for medium-load applications such as building frames and large shelving beams. The surface undergoes a fine galvanizing process, resulting in a uniform, smooth, dense, and defect-free zinc layer that effectively resists outdoor moisture and industrial corrosion, with an outdoor service life of over 20 years. Precision cutting ensures clean, burr-free cuts, allowing for direct installation without secondary grinding, significantly improving construction efficiency. The uniform wall thickness conforms to GB/T 3091-2015 standards, balancing structural strength and lightweight design, making transportation and processing convenient and labor-saving. From the supporting frame of steel structure factory buildings and the main components of municipal guardrails to the main frame of large greenhouses and the keel of commercial display racks, it is suitable for a variety of medium-load scenarios with its advantages of 'strong load-bearing capacity and high durability', making it a reliable material choice that balances practicality and cost-effectiveness.
40×80×1.6 Galvanized Rectangular Tube
This is a 40×80×1.6 mm galvanized rectangular tube, a commonly used profile in the construction and engineering fields. It is made from high-quality galvanized steel strip, with a cross-sectional dimension of 40mm width x 80mm height and a wall thickness of 1.6mm. It combines lightweight construction with structural stability -- reducing the overall load while meeting the strength requirements of frame construction and support systems. The hot-dip galvanizing treatment forms a dense protective layer, effectively resisting moisture and corrosion, making it suitable for long-term use in outdoor and humid environments and extending the material's lifespan. The product is manufactured using standardized processes, ensuring high dimensional accuracy and clean cuts, facilitating cutting, welding, and assembly. Bundled packaging makes transportation and storage more convenient, meeting the efficiency needs of batch construction. Currently, it is widely used in steel structure frames, photovoltaic supports, fences, decorative frames, and other applications, combining practicality and cost-effectiveness, making it a highly adaptable profile choice for industrial and civil projects.
40×44 Peach-Shaped Tube
Jia Yi Steel Pipe's 40x44 peach-shaped pipe is a galvanized pipe with an irregularly shaped cross-section, precisely sized to meet the needs of special applications. Made from high-quality steel strip through precision rolling and hot-dip galvanizing, the product boasts a uniform and dense zinc layer, offering excellent rust and corrosion resistance, making it suitable for complex environments such as outdoor and humid conditions. The peach-shaped cross-section design enhances structural stability, providing superior bending resistance and load-bearing capacity compared to ordinary pipes, while also offering good ductility for easy custom processing and installation. Currently widely used in fences, furniture frames, agricultural greenhouse supports, and decorative designs, it meets functional requirements while adding a unique aesthetic appeal to projects. Jia Yi Steel Pipe has its own standardized production line, ensuring each batch of peach-shaped pipes undergoes multi-dimensional quality inspection, including dimensions and coating. Custom lengths and packaging are supported, and efficient logistics ensures delivery, making it a highly adaptable choice for irregularly shaped pipe applications.

38mm 2.0mm Galvanized Round Pipe
This is a 38×2.0 specification galvanized steel strip round pipe, a general-purpose pipe material for both industrial and civil applications. It uses high-quality galvanized steel strip as raw material, with an outer diameter of 38mm and a wall thickness of 2.0mm. While ensuring lightweight characteristics, it possesses excellent structural load-bearing capacity, adapting to the strength requirements of various scenarios such as pipeline transportation and support erection. The surface is treated with hot-dip galvanizing, forming a uniform and dense zinc layer for effective resistance to corrosion in humid, acidic, and alkaline environments, significantly extending its service life in outdoor and harsh working conditions. The product adopts standardized production, with precise pipe diameter and uniform wall thickness. Cutting, welding, and threaded connection operations are convenient and efficient. The packaging format of bundled steel strips facilitates transportation and warehousing management, adapting to the supply rhythm of batch projects. Currently, it is widely used in water supply and drainage pipelines, electrical conduits, scaffolding erection, guardrail frames, and other scenarios, combining practicality and economy, making it a highly adaptable material choice.
