Sodium and magnesium contain less combustible impurities, and when extinguished, they simply glow. Galvanizing belongs to the electrochemical processing process which is widely used on the surface of steel. So it is, first of all, because zinc coating (especially after supplementary processing, such as chromate treatment and phosphating) resistance to atmosphere and water is more stable, and the galvanized process itself this is cheaper and simple.

Stainless steel barbed rope in the way of corrosion is not very, because the surface is not treated but rely on its own raw materials for corrosion resistance, so there will be no chemical reaction. After a long time of use, it will not rust like the corrosion layer on the surface of hot dip galvanized barbed rope, because the internal material of stainless steel barbed rope is the same as the material on the surface. The most obvious difference in a short time is the cross section of this piece, hot dip galvanized barbed wire because of surface anticorrosion treatment, so there will be rust in the cross section of this piece, and stainless steel barbed wire because the internal raw materials and surface raw materials are consistent, so there is no such situation.

Good galvanized wire, plating thickness of 3- 4 mm, zinc adhesion should be less than 460 grams/m, that is, the average thickness of zinc layer is not less than 65 microns. When the thickness of plated parts is greater than 4 mm, the zinc adhesion should not be less than 610 g/m, that is, the average thickness of zinc layer should not be less than 86 microns. Standard galvanized wire coating must be uniform, galvanized layer basically uniform with copper sulfate solution test etching five times no dew iron. For standard galvanized wire coating adhesion requirements, the zinc layer of plated parts should be firmly combined with the basic metal and have enough adhesion strength, after hammer test does not fall off, not convex.

Of course, these are limited to the maintenance of the indoor balcony, so outdoor, some of this is less than maintenance, some maintenance will waste resources, because of the expected life, in order to ensure the safety of the role, timely update is good.

Determine the size of the crate based on the actual size of the dog as an adult. In general, the cage should be three times the size of the dog’s body, so that the dog has enough room to turn around and so on.

For example, residential buildings make sure thresholds serve as entryways. Most of these components are made of wood and do not usually have a longer shelf-life because of environmental factors. Fortunately, the production of aluminum thresholds has made it possible for a more corrosion-resistant material that can last longer compared to wood. Furthermore, they can adopt a smoother shape to assist in accommodating wheelchairs, or other wheeled objects.
