Delta-seal is a zinc flake coating system. The system comprises an electroplated base layer and a Delta-seal topcoat which provides highly effective anti-corrosion. In tests carried out with neutral salt spray, Delta-seal compared with standard galvanized screws offered more than twice the corrosion resistance. In test compared with zinc yellow electroplated, Delta-seal offered more than 10 times higher corrosion resistance.
• Withstands ACQ, CCA, and LOSP timber treatments.
• Excellent chemical resistance
• Particularly suitable for multiple screw fixing
