The 36U U-shaped steel arch is a structural support component for underground mining and tunnelling, manufactured from 20Mnk manganese structural steel in compliance with GB/T4697-2008. Each metre weighs 35.87 kg, with standard lengths available from 8 to 12 metres. Its dimensions include an H1 of 138 mm, H2 of 17 mm, B of 171 mm, and M of 7.8 mm, designed to withstand high-stress environments in mining shafts and tunnel excavation projects.
This hot-rolled steel arch provides load-bearing support in soft rock and unstable strata, offering scalable carrying capacity and high cross-utilisation. The material’s manganese content enhances toughness and wear resistance, making it suitable for long-term deployment in harsh conditions. Typical industry use includes primary and secondary support systems, where modular assembly allows for rapid installation and adaptation to varying tunnel profiles.
Primary buyers are infrastructure and mining sector importers in Southeast Asia, Africa, and South America, where tunnel construction and mineral extraction are expanding. The product is traded in bulk volumes, often as part of larger structural steel packages for mine development. Its design allows for easy deformation under load, reducing the need for wood supports and improving environmental efficiency in underground operations.

Before ordering, verify the supplier’s compliance with GB/T4697-2008 and request mill test certificates for the 20Mnk steel grade. Confirm the dimensional tolerances for H1, H2, B, and M, as these are critical for structural fit and load-bearing performance. Check if the supplier provides third-party inspection reports for material composition and mechanical properties.
Logistics details to confirm include the supplier’s ability to handle bulk shipments of 8 to 12 metre lengths, as these may require special transport arrangements. Discuss Incoterms such as FOB or CFR, and clarify whether the supplier can arrange inland freight to the port of Handan. Lead times should be specified, as mining projects often operate on tight schedules.
Quality checks should include visual inspections for surface defects, dimensional measurements against the GB/T4697-2008 standard, and non-destructive testing for internal flaws. Request documentation such as packing lists, material certificates, and test reports. For secondary support applications, ensure the arches meet the project’s load-bearing requirements and are compatible with other support systems.
