1. consists of insulation fastener and red cap nail 2. Insulation fastener which is made of 100% original Raw material has the characteristics of not combustion -supporting,it has the unique design of tooth shape that can efficoently isolate the drive pin and mortar;stop the heat bridge effect. | |
3. adopting the patented step shank design can get the best value of drive pin’s peneteraility and reduce the destructiveness to the base material;we use high Steel to manufactere the drive pins which ensure the nail body high strength,high tenacity and fastening much saferand more reliable | |
When a fastener is driven into concrete,the concrete Around the fastener shank us displaced,this displaced Concrete commpresses against the shank creating a Friction gold.on addition,heat generated during the driving process,causes a sintering of the concrete to the Fastener. 1.the fastening effect will be affected by following factors. 2.Compressive strength of concrete 3.Fastener shank diameter 4.Concrete grade | |
When a fastener is driven into steel,the steel around the fastener shank is displaced.the displaced steel flows back around the shank and into the knuring creating a keying or in the case of smooth shank fasteners a friction hold.in addition,the heat generated druing the driving process,at tempartatures of approximately 900 degree,causes partial fusion of the fastener to the steel. A fastener driven into steel os influenced by the following factors: 1.base steel thickness. 2.Thesile strength of base steel 3.Fastener spacing and edge distance 4.Fastener shank diameter. |
