Shaped tubes Focusing on seamless steel pipes for 22 years, we are the source factory and look forward to cooperation. Plum blossom-shaped special-shaped steel tube Hexagonal special-shaped steel tube Hexagonal special-shaped steel tube Inner circle and outer square special-shaped steel tube Product Introduction Introduction to special-shaped steel tubes: Special-shaped steel tube is a pipe that breaks through the limitations of traditional round and square shapes, and has a variety of cross-sectional shapes. We use advanced production technology and select high-quality steel to ensure that each special-shaped steel tube has excellent performance and precision.
Features of special-shaped steel tubes:

• Diverse shapes: It can produce triangles, ovals, trapezoids, D-shapes, hexagons and other conventional shapes, and can also customise more complex irregular shapes according to customers’ special requirements to meet unique design needs.
• High-precision manufacturing: using advanced cold rolling, cold drawing, hot rolling and other processes, the dimensional accuracy is controlled within a very small range to ensure product consistency and adaptability, and reduce the adjustment process in construction.
• High strength and good toughness: high-quality steel is selected and specially treated to have excellent compressive, bending and torsional strength, which can maintain stable performance in harsh environments.
• Good surface quality: the surface is smooth and flat, without obvious defects, and surface treatment such as galvanising and painting can be provided according to needs to enhance corrosion resistance and aesthetics.

Application of special-shaped steel tubes：

• Architectural decoration: used for façade decoration of high-end buildings, indoor special-shaped structures, such as unique architectural shapes, artistic partitions, etc.
• Machinery manufacturing: the production of parts and components of special machinery and equipment, such as special-shaped shafts, frame structures, etc.
• Automobile manufacturing: It is applied to the frame, bumper and other parts of the automobile to optimise the structure of the automobile and improve the safety and aesthetics.
• Rail transit: It plays a role in the structural parts of rail transit vehicles to meet the needs of lightweight and high strength.

Product advantages 

• Diversified and all-round production system ：We have built a diversified production system, covering advanced production lines such as hot expansion, hot rolling, cold rolling, cold drawing, centrifugal casting, CNC machine tools, etc. Each production line is equipped with cutting-edge equipment and mature technology, accurately controls the production process, and efficiently produces high-precision and high-quality products to meet the diverse needs of various industries.
• Direct supply from the source factory: As the source factory of centrifugal casting, we eliminate all intermediate links and directly deliver the products from the factory to the customer. Dramatically reduced product costs, allowing you to obtain high-quality centrifugal casting products at a low price, as well as more direct and rigorous control of the production process to ensure consistent product quality.
• Strict quality control system: We build a whole-process quality control system. Strict testing when purchasing raw materials to ensure that the ingredients and performance meet the standards; Multi-channel detection gates are set up in production to monitor the dimensional accuracy, mechanical properties and surface quality of products in real time; The product is fully inspected before leaving the factory, so that you can rest assured.
• Perfect after-sales: We will pay regular visits to help customers solve problems and continue to improve.
