What is the choice of galvanized steel waterproof casing in the building?

1 . In the specific selection of the whole process has its own selection criteria.
 
In the case of specific selection, the key point of the product is completely critical. The small details of the product will determine the key aspects of the quality of the wall casing. Throughout the selection process, customers can check all manufacturers based on whether there is a gap on the surface of the manufactured product. Or check their surfaces for gritty eyes for identification. As long as all the wall thickness of the casing appears in certain conditions, there will be a high quality casing. This quality is better. In general, it is well worth the customer's choice.
 
Before casing production, carefully understand the engineering drawings and analyze the production and assembly methods of pre-built casing; when the pipeline encounters the shock wave of a large earthquake or surrounding explosion, it will vibrate strongly, again, because its walls are firmly locked, so that the energy of its internal structure cannot be transformed, leading to the destruction of the pipeline. In the current casing development of the specific selection of the whole process, according to the application site for selection. When choosing galvanized steel waterproof casing, you should choose the one with higher reputation or relatively popular as much as possible. The product is relatively large and can ensure a large number of quality factors.
 
2、Select according to the standard atlas.
 
Casing is divided into two types: hard casing and soft casing. 02s404 for casing standard atlas, that is, according to the standard atlas of wall casing specifications for classification. At this stage, the market is divided into national standards and non-standard, national standards in full accordance with the Ministry of Housing and Urban-Rural Development relevant 02S404 or 02S312 standard atlas implementation. The selection and production of materials have strict regulations on flange thickness, wing ring thickness, pipe diameter and thickness. Non-standard means that when the design and structure conform to the standard atlas, the thickness of all materials are required to be released. Although this product is not qualified, it does not affect the application. In the long run, the characteristics of the application may be somewhat inadequate.
