The anchor bolts consist of many specifications according to the thickness of insulating course, and it is widely used in the construction and decorating. The anchor bolts produced by our company possess many features as follows: Aging resistance, anti-dramatic changes in temperature, anticorrosive, cold and heat resistance; High bearing capacity and good tensile properties; High distortion and damp resistance, anti-vibration, noise absorption and good insulating quality and so on, so it’s widely used in thermal insulation of building.. The anchor bolts don’t need any other special installation tools but one hammer which is used to knock the bolts, so it’s easy to install. The galvanized screws have good anti-corrosion and durability nature, and nylon materials have adiabatic properties, so there will be no cold bridge in winter and high-efficiency, energy-saving and consistent.
