Roofing nails, as its name suggests, are designed for roofing materials installation. These nails, with smooth or twist shanks and umbrella head, are the mostly used type of nails with less cost and good property. Umbrella head is designed for preventing the roofing sheets from tearing off around the head of the nail, as well as offering an artistic and decorative effect. The twist shanks and sharp points can hold wood and roofing tiles in position without slipping. We adopt Q195, Q235 carbon steel, 304/316 stainless steel, copper or aluminum as material, so as to ensure the nails resistant to extreme weather and corrosion.
