Galvanised Flat Washers (HDG) are wide, heavy-duty washers commonly used in roofing applications. Their hot-dip galvanised finish provides superior corrosion resistance, making them ideal for outdoor and structural environments. These washers distribute load effectively, reducing stress on surfaces and ensuring secure fastening.
