Insulation of external wall insulation is dedicated Anchor nails,galvanized screws ,nylon tube and rising fixed wafer form. According to the thickness of the insulating layer,is divided into a variety of specifications.Widely used in construction and decoration,Housing production factory in the insulation layer of nails wide used. With aging ,the sudden change in temperature resistance, anti-corrosion, hear-hardy; High capacity, high pressure,good tensile properties; After loading is noteasy deformation cast reduce vibration, noise absorption and sound insulation characteristics. Installation is simple and can Hammering do not need special installation tools. Galvanized screws good solution corrosion,durability,and low heat transfer performance nylon material, no cold winter bridge ,efficient energy.
