Welded wire mesh has become an indispensable basic material in mining tunnels, tunnel support, foundation engineering, and industrial projects. For many engineering companies, choosing welded wire mesh is not only a matter of the material itself, but also relates to subsequent construction efficiency, structural stability, and long-term maintenance costs. At our factory in Yongnian, Handan, Hebei, the production of welded wire mesh has formed a relatively mature and stable process. From raw material intake to finished product packaging and delivery, all steps are completed within the same industrial chain, resulting in short transportation distances and controllable supply cycles. This is…

Application Value and Structural Characteristics of Split-Type Friction Bolts in Mine Support Split-type friction bolts have become increasingly common in mine roadway support in recent years. Compared to traditional anchor bolts, their structure is simpler, consisting of a steel sleeve and a core rod. They achieve rapid support through friction, making them a typical "ready-to-use" product, particularly suitable for mining environments with rapid rock deformation or limited construction conditions. Structurally, the outer tube of the split-type friction bolt is longitudinally slit or pressed, allowing it to elastically expand after insertion into the borehole. When the core rod is hammered in…

Mining: Driving Progress Through Safety, Innovation, and Sustainability The global mining industry is at a critical juncture. With advancing electrification, increasing infrastructure projects, and the rise of renewable energy, the demand for raw materials is growing, and mining companies must adapt to this change through safer operations, smarter technologies, and stronger supply chains. 1. Soaring Demand, Increased Responsibility Urbanization and infrastructure expansion are driving demand for minerals such as copper, lithium, and rare earth elements. Leading research indicates that the mining industry will need to supply far more materials than many anticipate over the next decade. Meanwhile, regulatory pressures and…

U-Shaped Steel Arch Beam: The Backbone of Stable Underground & Tunnel Construction If you’ve ever walked through a mine tunnel, driven through a mountain highway tunnel, or even visited an underground metro construction site, you’ve probably seen the quiet hero holding everything together: the U-shaped steel arch beam. It’s that curved, U-shaped steel structure spanning the top and sides of the tunnel, keeping loose rock, soil, and debris from caving in. I’ve spent 15 years working on underground projects—from small mine shafts to 6-lane highway tunnels—and I can say without hesitation: when the ground gets unstable, this beam is the difference…

Welded Steel Mesh: The Versatile Workhorse for Construction & Industrial Projects If you’ve ever hauled materials on a construction site, helped build a backyard fence, or even watched a crew patch a highway, you’ve definitely seen welded steel mesh—you just might not have called it by name. It’s that grid of steel wires or bars fused together at every crisscross, popping up in everything from concrete slabs to chicken coops. I’ve been swinging hammers and laying concrete for 12 years now, and I’d bet my toolbelt I haven’t done a single major job without it. Why? Because it’s tough, doesn’t mess…

  If you’ve ever swung a wrench in an underground job—mines, tunnels, slope work—you know rock bolts are the difference between a safe site and a disaster waiting to happen. But here’s the thing no one talks about enough: that bolt is useless without a rock bolt nut. It’s the tiny, tough piece that locks everything down, turning a plain metal rod into something that can hold back tons of rock. I’ve seen crews cut corners on nuts to save $50—and end up shutting down for a week when half the bolts came loose. Trust me, this little part isn’t…
