Anchor plate can be positioned in the drilled hole, and the rod body is well centered.The anchor plate is one of the parts of the pipe joint bolt,its material is made of welded ring and rolled head, and the ring cutting is made to make the retaining ring.
Dome Plates provide high load bearing capacities and are available in sizes 150 mm and 200 mm square, typically used with Solid Bolts, Strata Bolts and Cable Bolts. Dome plates are designed in-house to provide optimal surface support in a range of strata conditions.
Material:Mild Steel

DOME PLATE FEATURES
The product is a supporting plate for mine roadway and tunnel,especially in coal mine roadway. The center of the plate has holes for the bolt to pass through,the central part is a hollow spherical bulge, there is a platform at the top of the dome plate can be made of steel or cast iron,and cast iron brackets can be reinforced around the ball. The high-quality steel plate improves the internal stress state of the anchor plate which has the advantages of strong bearing capacity and saving material.
applicaton and uses
Primary use is strata reinforcement in underground mines. Designed to help prevent loose material from falling between the roof bolt patterns and provide strength to the immediate roof.
The Dome Plate is used in conjunction with bolts to stabilize structures, earthen embankments, and to provide support over larger surface areas.
As an important part of the bolt support system. the bolt plate has a direct effect on the supporting effect of the bolt. Plate is the role of the lock nut tightening torque generated by the thrust is transmitted to help, at the beginning of the anchor force,at the same time the pressure of the roadway roof will help to anchor, working Resistance common reinforcement of surrounding rock, prevent displacement of the roadway roof to help. So when choosing a tray,the first is to satisfy the match of the bolt and the bolt body on the strength,to avoid the bolt hole caused by the insufficient strength of the bolt plate. The second is to satisfy the bolt and anchor rod on the supporting structure of the match,avoid the anchor rod body with the supporting plate on the supporting structure caused by the mismatch anchor rod body and the nut uneven, influence of roadway supporting effect.
