For the wide use of screen, the state has regulations. You also specify the diameter size, mesh size, or usage method. For plastering mesh, mesh should be less than 20 and diameter greater than 1 nm. Not only are specifications specified, but safety is preferred if wire mesh is used in exterior plastering mesh. If you fall, the consequences are unimaginable. Therefore, the application of norms should be combined with reality.

Zinc coating on steel and ferrous metal plays an anodic role, it is commonly used for those parts subjected to atmospheric or water action, but zinc coating only when the water temperature below 60℃, the anode properties. When the temperature is higher, the potential changes and the zinc to iron becomes the cathode. Therefore, for parts subjected to hot water (such as steam boilers), the zinc skeleton must be approximately 70 microns thick and void free. For parts subjected to low or normal temperature or atmospheric action, zinc coating without pinholes is not necessary.

A. When the thickness of the plating is 3-4 mm, the zinc adhesion should be less than 460g/m, that is, the average thickness of the zinc layer is not less than 65 microns.

Speaking of pets, we have to talk about parrots. Because it’s easy to take care of, and it can talk, talk to you, and make you laugh. Parrots love to climb, so there is a cage with bars that are made up of horizontal bars rather than vertical bars, because this makes climbing easier for the parrots.
