Best Quality Perforated Metal Sheets
Advantages include:
1. Raw material is made of Q235: Q235 material is used as raw material, which has good weldability, plasticity and corrosion resistance and is suitable for various engineering occasions.
2. Higher steeliness and strength: the product has higher steeliness and strength, which can withstand greater loads and pressures and provide more reliable support and protection.
3. 54 times higher flexural section modulus of the guard plate: Through optimized design, the flexural section modulus of the guard plate is significantly increased, which enhances the deformation resistance and load bearing capacity of the product.
4. Hardening effect during cold pressing improves the tensile strength by 28-46%: The hardening effect during cold pressing improves the tensile strength of the guard plate, which improves the endurance and stability of the product.
Product Details:
Mining W-type sheathing is a very important material for mine support and tunnel support.It is designed to effectively improve the overall effect of the anchors and show good stability in incomplete roof rock formations.This kind of sheathing is made of Q235, Q235, Q235, Q235, Q235, Q235, Q235, Q235, Q235 and Q235. This type of shield is made of Q235, and its unique cross-sectional shape allows it to form a complete load-bearing structure when combined with anchors to support rock formations or tunnels.W-type shields are widely used in underground mine passages, face cuttings, chambers and other areas, providing important support and protection for workplace safety.

Product Description:
W-type guard plate is a new type of mine support materials, using the thickness of 3-5mm, the width of 180-320mm range of rolled steel plate, cold bending treatment into a W shape, and in the middle of the process with the anchor rod spacing equal to the anchor rod hole. By connecting several scattered anchor rods, the W-shaped shield forms a whole bearing structure, which significantly improves the effect of anchor support. It is especially effective in incomplete roof formations, and also has the advantages of reducing support costs and saving support steel. This kind of shield is unique in design, has high practical value, and is suitable for all kinds of mines and tunnels support projects.
W-type guard plate main purpose
Combined with various anchors to form an anchor plate support, it connects scattered multiple anchors together to form a whole load-bearing structure. This type of shield is widely used in roadway support projects in underground coal mines, working face cuttings, chambers, etc. It can effectively deal with unstable surrounding rocks and provide good support effects.The unique design of W-type shield can improve the overall effect of anchor support, and it plays an important role in mining and tunneling projects to ensure the safety and stability of the working area.
