从China供应商批发进口29 U Steel Arch — FOB条款

The 29U steel arch is a passive support system designed for coal mine tunneling and underground excavation, engineered to handle the dynamic load conditions of mining environments. Manufactured from 20Mnk high-strength low-alloy steel, it delivers exceptional tensile strength, compressive resistance, and toughness, making it a reliable choice for secondary support in mine tunnels and mountain tunnels.

This U-section arch conforms to standard mining support specifications, with the 20Mnk grade offering typical yield strength of 355 - 460 MPa and elongation of 20 - 25% under standard testing conditions. The 29U profile is a typical size in the U-steel support category, balancing load-bearing capacity with ease of installation in confined spaces. Surface treatment is typically hot-dip galvanized to resist corrosion in humid underground conditions.

Primary buyers include mining contractors, tunneling firms, and coal mine operators who require durable, long-lasting support structures. The arch is supplied in bulk lengths, with standard segments of 2.8 - 3.0 meters, and is compatible with locking plates and bolts for modular assembly. Export markets often request FCA or FOB terms from Zhengzhou port, with packaging optimized for containerized shipment to reduce freight costs.
