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. ‌
