Color steel plates are often used in construction projects. It is indispensable today, but it is worth mentioning that there are many types of color steel plates and their thicknesses have individual differences. Many people do not understand the specific specifications. , How to choose the thickness of the color steel plate is even more difficult to start, then how to choose the thickness of the color steel plate?
Generally speaking, the color steel plate is divided into two layers, and the size depends on the customer’s requirements. In most cases, 0.476MM color steel plate is used for the lower layer, 950-type tongue and groove board is used for the wall surface, and 0.376 color steel plate is used for the inside and outside. Of course, there are special circumstances, and some mobile homes are galvanized steel with a thickness of 0.35–0.4 mm.
If it is an outdoor simple color steel plate movable room, the color steel plate wall plate uses a 0.4 cm thick galvanized plate, the zinc content of the galvanized is 60-80 grams, and the foam material for the sandwich filler can be used.
Standard information on the thickness of color steel plates used in international standard purification plants, operating rooms, etc. Wall mobile rooms should use a thickness of 0.6 cm or more, and the zinc content of galvanized should be over 110 grams. The purpose is to prevent rust and fill the color steel plates. It is forbidden to use polyvinyl chloride, that is, foam board, and the fire rating has national standards.
The outer layer of the wall is made of G550 high strength color aluminized zinc steel plate, and the thickness of the substrate is not less than 0.60mm. The inner layer is made of high-strength aluminum-zinc plated steel, and the thickness of the substrate is not less than 0.50mm. The thickness error is ± 0.02mm. The wall insulation material is ultra-fine glass wool.
Color steel plate coating weight: the amount of aluminized zinc ≥180g / m2 (front and back);
Wall panel: AZ185 hot-dip aluminized zinc steel plate;
Paint coating: 20um thick fluorocarbon topcoat on the front of the outer panel, 5um thick epoxy primer;
Organic coating: PVDF fluorocarbon-polyester coating system is selected;
15um thick polyester finish on the front of the inner panel, 5um thick epoxy primer;
20um thick polyester topcoat on the back, 5um thick epoxy primer;
Color steel plate thickness (substrate): outer plate ≥0.6;
5um thick polyester finish on the back, 5um thick epoxy primer.
The polystyrene color steel sandwich panel is composed of two layers of color-coated steel sheets inside and outside, and is coated with adhesive glue on the steel sheet by an automatic composite molding machine, and thin-wall channel steel is embedded on both sides of the sheet. And blanks made of sheet.
Machine plate specifications: L × 1150 × 50mm, L × 1150 × 75mm, L × 1150 × 100mm, color steel plate manual plate specifications: L × 985 × 50 color steel plate thickness: 0.426mm, 0.476mm, 0.50mm, 0.60mm , Polystyrene density ≥18kg / m3 Thermal conductivity: 0.041w / mk Combustion performance: B1 level (flammability), the maximum operating temperature is 100.
In the production process of color steel plate, the thickness dimension must be carried out according to certain specifications. Among them, the thickness of the color steel plate is required to be between 50-250mm. If it exceeds the specified range, it is regarded as a substandard product.
The requirements for the size of the color steel plate are: the width is generally 1150mm, and the length can be changed according to user needs. The thickness and size of the color steel plate largely determines the role and function of the color steel plate, so it is necessary to strictly control the production process.
