Import 25 U Steel Arch — Buy in Bulk from Supplier in China

The 25 U Steel Arch is a passive mine support product manufactured from 20MnK alloy steel, featuring a U-shaped cross-section with 110mm height, 17mm thickness, and mass of 24.76 kg/m. Produced through hot rolling and acid pickling, this section is classified as heavy section steel in the U-type category, with smelt quality designated as quality by the source description. Henan Zongxiang Heavy Industry Import And Export Co, .ltd. offers this product in single beam, double beam, treble beam, and grade beam configurations, suggesting flexibility in support system assembly for varying load conditions.

20MnK steel in the 25U specification delivers the tensile strength, compressive strength, and toughness properties required for yielding support in coal mine roadways and similar underground excavations. The hot-rolled treatment establishes the U-section geometry through controlled deformation at rolling temperature, with subsequent acid pickling removing surface scale to improve corrosion performance. The single, double, treble, and grade beam options refer to common assembly patterns where multiple U-sections are nested or combined with lacing and blocking to form load-bearing arches of increasing capacity. Standard industry practice employs these configurations for different roadway widths and ground conditions, with the specific combination selected through empirical design charts or numerical modelling.

Mining contractors, tunnel engineering firms, and underground infrastructure developers source 25 U Steel Arch for installation in coal operations, metalliferous mines, and civil tunnel projects where conventional bolt-and-mesh support is insufficient. The quality smelt designation indicates controlled steelmaking practice, though buyers should request actual ladle analysis and mechanical test data for verification. Trade terms, minimum order quantities, and delivery schedules from the Zhengzhou-based supplier require direct confirmation, as these operational details are absent from the listing. Packaging for export typically involves bundled lifting, with steel strapping and wooden separators to prevent transit damage, but confirm specific preparation with the supplier before shipment booking.

Henan Zongxiang Heavy Industry Import And Export Co, .ltd. operates from Hanghai Road, Guanzhenghuizu District, Zhengzhou, Henan Province, China, postal code 470000. The company profile on this listing shows a harbour trust tier with zero recorded response rate and zero average response hours. These indicators suggest limited platform engagement or a profile where enquiry data has not accumulated, rather than necessarily reflecting operational capacity. The supplier sources or distributes 25 U Steel Arch with specifications traceable to a mill of substantial production scale.

No founding date, registered capital, employee numbers, or annual revenue figures are provided in the listing. No quality management certifications, export licences, or client references appear. The product description includes technical detail on configurations and material quality, but the relationship between Zhengxiang and the actual producing mill remains unspecified. Buyers should request company registration documents, export licence verification, and evidence of previous successful shipments before committing to substantial orders. The multiple beam configuration options suggest familiarity with mining support applications, but technical competence should be validated through direct communication.
