Description :
W-steel strip is a new type of high-strength support material designed specifically for coal mines, tunnels, and underground engineering, widely used in anchor rod tray systems for roadway roofs and supports. Its unique "W" - shaped cross-sectional structure is precision cold-rolled and has excellent bending stiffness and bearing capacity, which can effectively disperse the surrounding rock pressure and improve the overall stability of the support system. Compared to traditional flat pallets, W-steel strips can provide higher structural strength at the same thickness, while reducing their own weight and facilitating transportation and on-site installation.
The product is made of high-quality low-carbon alloy steel as raw material, and is processed through multiple passes of rolling, punching, and straightening. The surface is smooth and free of burrs, and the hole position accuracy is high, ensuring a perfect fit with accessories such as anchor rods and nuts. Standard installation holes are reserved at both ends of each steel strip, and a reinforced corrugated structure is installed in the middle to significantly enhance compressive and deformation resistance, suitable for long-term support needs under high stress and large deformation geological conditions.
Typical application scenarios include: coal mine tunnels, metal mine excavation faces, initial support for railway and highway tunnels, and reinforcement engineering for water conservancy tunnels. The target customers include mining groups, infrastructure construction units, support material distributors, and safety equipment suppliers. This product complies with industry standards such as MT/T 146.2-2011 "Resin Anchor Rod Part 2: Metal Rod Body and Its Accessories", and supports customized length, aperture, and surface treatment (such as galvanizing, spraying) to meet the anti-corrosion and mechanical requirements of different working conditions.
As a key component of modern mine safety support, W-steel strip not only improves construction efficiency, but also significantly reduces the risk of roof collapse accidents. It is an important basic material for achieving green mining and intelligent mining. Batch procurement can provide testing reports and quality assurance certificates, support on-demand cutting and packaging, and adapt to various types of automated support equipment.
