Import 12# Mine Steel Arch - Zxsteel Group — Buy in Bulk from Supplier in China

This 12# mine steel arch is a pre-formed support structure fabricated from mine I beam sections, designed for immediate installation in underground tunnels and roadways. The arch is manufactured from Q345B steel, a grade offering higher yield strength (typically 345 MPa) than the Q275B used in raw beams, providing greater resistance to ground pressure. It is supplied as a complete arch set, ready for assembly, and is a common solution for secondary support in mining and tunneling projects.

The product's characteristics, as listed, include high pressure resistance, long support time, and ease of installation. Specific dimensional tolerances are provided: the outer edge deviation of the I-steel shall not exceed 2.4% of the leg width, bending deflection shall be no more than 1.0 mm, and eccentricity shall be within 2% of the leg width. These tolerances are critical for ensuring proper fit and load distribution when the arch segments are bolted together on-site.

Buyers for this product are typically mining engineering firms, tunnel construction contractors, and equipment suppliers to the underground resources sector. The arches are used for primary support in new excavations and for reinforcing existing roadways. When sourcing, it is essential to clarify whether the arch is supplied as a single unit or in segments, the included connection hardware, and the exact radius or profile dimensions to match your tunnel cross-section.
