For the reverse coating, the most appropriate selection is that if the application of color coated steel plate is double plate, select double-layer structure, that is, one layer of reverse finish, one layer of reverse paint. Topcoat is the same type as
the reverse. Choose a layer of polyester with light color (such as milky white). If the application of color coated steel plate is composite type or sandwich plate, a layer of epoxy color coated galvanized sheet adhesive with excellent adhesion and
corrosion resistance shall be applied on the reverse side.
In recent years, with the continuous enhancement of national environmental inspection, the traditional production and manufacturing of galvanized sheet industry has to pay more attention to environmental protection. For color coated sheet manufacturers,
accelerating environmental protection reform and promoting industry upgrading has become the primary goal of development.
Some enterprises don't pay much attention to the quality of color steel coil when building their own factory, or they don't
know about this kind of building materials. They think that the quality should be the same, but they don't know until the factory becomes very ugly.
Sixthly, the color coated steel plates of different manufacturers and batches are selected for the
same project of color coated steel plates for engineering construction. In fact, the colors are the same at the construction site, but after two years of direct natural light, the color analysis charts of different manufacturers of different coatings
are not the same, resulting in serious color deviation. There are so many cases. Even the products of the same dealer are strongly required to be ordered for the same project for many times. Due to different production batch numbers, the products of different
dealers of architectural coatings will be selected, which improves the color deviation.
As we all know, color coated boards play an important role in the construction industry, and the construction industry has always been leading the development
trend of color coated boards. It is very necessary to know what color coated board is used in the construction industry.
In order to prevent crushing, coil steel is usually not stacked. When stacking thick steel plates, the height of stacking column
shall be strictly restricted, and the weight and limit of plate package shall be placed below. The structural mechanical function and some coating functions of the color coated plate, such as pencil hardness, T-bend value and impact energy value, may
change with the expansion of storage time, so the customer is considered to rush to production and processing. The storage area shall be provided with indoor space for the application of hoisting machinery and equipment.
