It is made of stainless materials, which has higher intensity and broader applied conditions. Good capacity of welding and anti-corrosion determine that anchor bolt can suit for special construction conditions, such as: undersea tunnel, harbor, etc. Compared with common anchor bolt, stainless self drilling anchor bolt has certain resistance to air, water and chemical reagents.
This kind of bolt adopts hot-dip galvanizing method. It forms a zinc oxide diaphragm or zinc hydroxide diaphragm on the surface of anchor bar, plate, nut and drill. It not only has anti-corrosion feature, but also is beautiful.
There are two corrosion-prevention measurements on the bolt surface: epoxy coating and hot-dip galvanizing.Epoxy coating: an epoxy resin coating material, which is acid-resisting and solidified at room temperature.
