Product Details

In general, structural pipe is a type of steel construction pipe that meets certain standards of chemical composition and mechanical properties. This pipe can be used for a wide variety of structural applications and there are variety of types of structural pipe available. Common types of structural pipe include:Seamless Steel Pipe: Seamless steel structural pipe is a durable pipe product that is commonly used for dock piling, pipe piling, caissons, and bollards.ERW Steel Pipe: This structural pipe is typically known to the construction industry as high quality line pipe and it is commonly used by the oil and utility companies. This steel pipe can be used for sign pole, column, dock, and tunnel construction.Spiral Steel Pipe: This is an economical and durable type of structural pipe that offers long lasting durability for things like road casing, piling and trenches.DSAW Carbon Steel Pipe: This structural pipe is welded on both the OD and the ID. It is available in many different grades and is used for road casing, road boring, culverts, and more.Fence Pipe: This is a type of structural pipe that is becoming popular for building fences because of its high durability and strength. This structural pipe is used for enclosing parks, parking lots, and more.Culvert Pipe: This type of pipe is not necessary a high quality or extremely durable structural pipe, but rather a construction pipe used for diverting water under and around driveways, water and sewer systems, drainage systems, and temporary bridges.

Custom-made irregular-shaped tubes

Irregular-shaped tubes are hollow steel materials with non-standard irregular cross-sections, which are different from ordinary round tubes. We support customized production based on drawings and samples. The cross-section, material, wall thickness, and length can be adjusted according to working conditions to reduce subsequent cutting and welding processes and improve the overall strength and assembly accuracy of the components.

Packing and shipping

Our company has passed ISO9001 quality management system certification, Our Mill product with CE/EN10204 / ASTM/Classification society certificate/CASO/BIS etc certificate.All the customers give good appreciation to our products.We are glad to be your good partner.

 

 

Application Areas

Steel is widely used in steel structure workshops, bridge frames, main structures of high-rise buildings, and infrastructure construction (such as highways, oil and gas pipelines). Its high strength properties ensure load-bearing stability and seismic performance. In ship manufacturing, steel is used to build hull structures, decks, and internal components. Hot-rolled coils rely on their load-bearing capacity to adapt to harsh environments. ‌
