Mining support materials
Mining and tunnel support materials (commonly referred to as roof straps), used in combination with rock bolts to form an integral load-bearing structure.
W-Shaped Steel Strap / Mining Support Steel Strap
W-shaped steel straps are special components for mine support and tunnel reinforcement. Fabricated from Q235 or high-strength alloy steel strips via cold bending to form a W-shaped cross-section, they connect scattered point supports into an integrated load-bearing structure when used with anchor bolts. Compared with flat steel straps, the product features a 37-fold higher section modulus for bending resistance and approximately 70 times greater rigidity, while cutting steel consumption by 30% to 50%. Widely adopted in coal mine roadways, tunnel projects, chamber reinforcement and other scenarios, it serves as a high-efficiency support product replacing traditional I-beam supports.
T-shaped Steel Strip
This T-shaped steel strip is integrally bent and formed from Q235 steel strip with overall hot-dip galvanizing for anti-corrosion treatment. Its standard T-shaped structure delivers uniform stress distribution and strong deformation resistance and load-bearing capacity. It comes in a full range of specifications and supports non-standard customization, and is widely applied in projects such as mine roadway support, curtain wall embedment, slope reinforcement, and pipeline and equipment fixing. Featuring an integrated weld-free structure with a complete galvanized coating, it combines high strength with long-term rust prevention, and allows easy installation suitable for various construction scenarios.
Steel Strand Anchor Cable
Steel strand anchor cable is a prestressed anchoring product twisted from multiple high-strength low-relaxation steel wires, commonly adopting the 1×7 structure with a tensile strength grade of 1860MPa. It features high bearing capacity, low stress loss, flexibility and easy construction. It restrains surrounding rock deformation by actively applying prestress, and is widely applied in geotechnical reinforcement projects including mine roadways, tunnels, slope treatment and deep foundation pit support. Matched with anchors, bearing plates and grouting systems, it can form a complete support scheme to effectively enhance rock mass stability and engineering safety factor.
Lattice Steel Beam
Lattice steel beam is a type of steel structural component applied in industrial and mining support, steel structure connection and engineering load-bearing scenarios. Designed with regular hole positions and a lattice beam body, it facilitates on-site positioning, assembly and bolt fastening. Customizable in length, cross-sectional dimensions, hole spacing, plate thickness, material and surface finishing based on project drawings or sample requirements, this product suits multiple working conditions including mine roadway support, industrial factory buildings, equipment support and temporary construction shoring. Featuring neat structure and flexible installation, it allows bulk transportation and centralized on-site construction, serving as a commonly used auxiliary load-bearing component in industrial and mining projects as well as steel structure works.
