High Tensile Steel Self Drilling Anchor Plate With Domed Camber Structure And Hot Dip Galvanized Finish
Premium self drilling anchor plate, domed rock bolt plate, hollow anchor bearing plate for self drilling anchor bolt system. High load steel anchor plate for underground mining, tunnel forepoling, slope soil nailing, micropile reinforcement. Custom size hot dip galvanized anchor plate compatible with R25 / R32 / R38 / T40 hollow bar, factory direct supply for global geotechnical engineering projects.
What Is Self Drilling Anchor Plate
The self drilling anchor plate is a pressed thick steel plate with central concave dome design, specially matched with fully threaded hollow self drilling anchor bars, anchor nuts and couplers in one complete anchoring set. Unlike flat ordinary steel sheets, the integrated domed camber structure is the key technical innovation of premium self drilling anchor plates :
After tightening the anchor nut, the arched surface evenly disperses the axial tension of hollow anchor bar to rock / soil working face, avoiding local pressure damage to loose surrounding rock
Enlarged force bearing area reduces single point stress, greatly improving the overall anchoring pull out resistance of SDA system
Central reserved hole precisely fits outer thread of hollow bar, zero gap assembly prevents nut slipping under long term ground deformation
In the full construction flow of self drilling anchoring (drilling + grouting + anchoring integrated process), the anchor plate bears the permanent tension transferred by grouted rock mass, forming a stable composite support arch together with hollow bar and cement grout, fundamentally controlling surrounding rock displacement in complex geological layers.
