Installation and production of galvanized waterproof casing.

Galvanized waterproof casing is divided into hot plating and cold plating, waterproof casing after galvanization in terms of corrosion protection is very daunting, the appearance is also beautiful, waterproof role is also relatively good. Hot dipped galvanized thickness is thicker and has the advantages of symmetrical coating, strong adhesion and long service life. It is evenly coated with a layer of zinc. It prevents the erosion of other chemicals such as, water vapor and protects the steel strip.

Galvanized waterproof casing needs to penetrate the wall of the structure is concrete, galvanized waterproof casing through the wall when generally level with the wall does not need to extend. Through the floor slab, generally out of the gross floor 5 cm. Through the pipe installation is completed, the pipe and casing gap filled with flexible waterproofing material, and the end of the connection is painted with sealing paste.

Galvanized waterproof casing installation: mainly civil air defense equipment specified in the cable and sealing steel in the villa basement cable through or into the civil air defense engineering room when welding, with explosion-proof type effect. According to the building plan, structural pipe surface drawings and building elevation drawings, to determine the length of the casing then according to the drainage plan and large sample drawings, and refer to the standard set of drawings to make.

Prefabricated butt galvanized closed waterproof casing, must be solidified after a period of time before use, such as moving in advance, it will make the interface cracks. Galvanized closed waterproof casing pipe installation, according to the prescribed procedures should be water pressure test, if omitted this process may leave hidden dangers to the project.
