A color steel plate is a steel plate with an organic coating. It is divided into single board, color steel composite board, floor board and so on. Widely used in large public buildings, public buildings, mobile panels, and walls and roofs of integrated houses. The substrate of the color steel plate is a cold rolled substrate, a hot-dip galvanized substrate and an electrogalvanized substrate. The coating types can be classified into polyester, silicon modified polyester, polyvinylidene fluoride and plastisol.
Color plate thickness standard
The surface state of color steel plates can be divided into coated plates, embossed plates and printed plates. It is widely used in construction appliances and transportation industries. It is mainly used in the construction industry for steel structures, airports, warehouses and refrigeration industries and businesses. Building roofs and doors, etc., civil buildings use less color steel plates.
Generally, the thickness of the color steel plate is about 50-250mm, and its width is between 1150 and 1200mm. Due to continuous molding, its length can be determined according to different needs. The sandwich panel of the general color steel plate is often inserted into the tongue-and-groove type, which has the advantages of convenient installation, time saving, material saving, good flatness and high strength, and is particularly suitable for a ceiling and a partition system. Core material properties: A, polystyrene Bulk density: ≥15kg/m3 Thermal conductivity ≤0.036W/m.K Maximum operating temperature: about 100°C.
Color steel plate common specifications
950 corrugated color steel sandwich panel: it is a combination of corrugated board and sandwich panel, which is three times stronger than the ordinary flat color steel sandwich panel. The hidden self-drilling screw is connected with the roof truss without destroying the color coated board. The exposed part prolongs the life of the color steel sandwich panel; the plate and the plate are connected by a snap cap type, which is convenient for construction and improves the efficiency, and the maximum feature is not easy to seep.
Rockwool heat insulation color steel sandwich panel: Its core material is made of basalt and other natural ore as the main raw material, melted into fiber at high temperature, added with appropriate amount of binder, and solidified and processed. The product is suitable for industrial equipment, construction, ship insulation, sound insulation, etc., and is suitable for purifying rooms, explosion-proof fire-proof workshop ceilings, partitions, etc.
The bond strength of the sandwich panel of PU polyurethane color steel sandwich panel is not less than 0.09MPa, the combustion performance of sandwich panel reaches B1 grade, and the flexural capacity of sandwich panel is Lo/200 (Lo is the distance between supports) The bending capacity of the sandwich panel is not less than 0.5Kn/m2.
Polyurethane edge-sealing glass wool, rock wool sandwich panel: This color steel plate is made of high-quality color coated steel plate as the surface material, continuous cotton fiber rock wool, glass wool as the core material, high-density rigid foamed polyurethane for the mouth The filling, after high-pressure foaming curing, automatic dense cotton cloth and composite molding by super long precision double track control, the fireproof effect is better than the pure polyurethane sandwich panel.
