Self Drilling Roofing Stitching Screws

Our self drilling screws are designed to provide exceptional corrosion resistant capabilities. These screws are especially applicable in an outdoor environment where the screws are exposed to the contamination of the natural atmosphere. The heavy metallic zinc coating on the screws are coated with method of plating which utilises mechanical energy to deposit tin zinc compound metals on to its surface. This method of plating provides far more advantages as compared to the conventional method of electroplating the zinc to the screw.
