INTERkraz offers resin anchor rock bolts available in four varieties in addition to the washer type - round, square, or triangular.

Durability is a desirable feature in industries such as mining and construction. Equipment must not fail under tough operating conditions. Made from the highest quality material and manufactured using state-of-the-art technology, rock bolts from INTERkraz are characterised by impressive strength. Tensile strength is up to 500 MPa, so they may be used even in extreme conditions prevailing in mines of hard coal, zinc, lead, copper, salt, and wherever safety and reliable quality are the priorities.
