External wall insulation nails are also called external wall anchor nails, external wall anchor bolts, etc. External wall insulation nails are mainly used to fix the insulation board in the external wall insulation system. Plastic expansion insulation nails are divided into various specifications, depending on the thickness of the insulation layer, and are widely used in building decoration. Insulation nails are widely used in the insulation layer of houses. It has the characteristics of anti-aging, anti-temperature sudden change, anti-corrosion, cold and heat resistance; high bearing capacity, high pressure bearing, good tensile performance; not easy to deform after loading, moisture-proof, vibration-slowing, noise absorption and good insulation, etc., and is easy to install.

Insulation nails are a special engineering plastic expansion nails for fixing the insulation board to the wall. The insulation nail consists of three parts: one is a sleeve made of nylon; the second is a galvanized steel screw in the sleeve; the third is a nylon disc in front of the sleeve (used to cover the insulation board). Its length varies according to the thickness of the insulation board. No special installation tools are required. Galvanized screws solve the corrosion problem very well, with good durability, and the nylon material has low heat transfer performance, no cold bridge in winter, and high efficiency and energy saving.

Performance parameters: According to JG158-2004 exterior wall insulation standard; JG149-2003 "Expanded polystyrene thin plaster exterior wall insulation system" standard, single insulation nail load ≥ 0.3KN anchor tube diameter 0.7-0.8 thermal conductivity <0.06 anchor nail outer plate; 50MM insulation nail is a special anchor for exterior wall insulation, consisting of galvanized screws, nylon expansion tubes and fixed discs. According to the thickness of the insulation layer, it is divided into various specifications. It is widely used in building decoration. The insulation nails produced by our factory are widely used in the insulation layer of houses. It has good weather resistance and anti-aging performance, and is long-term stable in a temperature environment of -40℃ to +80℃. It is anti-vibration, anti-weathering, anti-fracture, firm and durable.
