Home >> SDA Plate

SDA (Self-drilling Anchor) systems drill and grout simultaneously, offering high load capacity and adaptable reinforcement for soil nails, micropiles, and rock bolts.

The SDA Bearing Plate, together with the nut, forms the “nail head” or “pile head,” the key point where the anchor’s load is securely transferred to the ground.
