Heraklith® DDS plus concrete screw is specifically suited for mounting wood wool cement panels. The concrete screw is made of steel with a special corrosion class C3 duplex surface treatment. Comprehensive international fire testing has shown that combining DDS plus screws with the Heraklith Tektalan A2 or the A2 Decorative panel results in excellent performance in fire-resistant applications. The screw head is depressed evenly, allowing the plastic head of the DDS plus screw to perfectly connect to the wood wool structure.
