In general, you can choose according to the standard color of the factory, which can reduce the workload in the early stage of production. If special colors are needed, because the paint needs to be prepared in the paint factory first, and the various properties can meet the requirements before production, the production time from order to color plate will be longer. In addition to the major color systems of major factories, the main color system standard of the color steel industry is the German European standard color card (1927). The Chinese translation is: Raul color card (RAL K5, RAL K7, … ).

The gloss of the coating surface measured with a 60 degree reflection angle, the larger the value, the higher the gloss. Generally, the color-coated board for home appliances has high gloss. The coating used on the building is medium or matt, ranging from 30 to 55. This is because the high-gloss coating is used to reflect the sunlight on the building and is dazzling. Indoors, it is easy to cause visual fatigue under the light at night.

Precautions for color coated steel plate design

Galvanized steel coil for roofing panels

Of course, the quality of the color-coated steel sheet mainly depends on the design of the color-coated steel sheet, but if the processing and installation equipment and methods are improper, it will also cause damage to the appearance and service life of the final product to varying degrees.


The good appearance and excellent performance of the color-coated steel sheet awakened the interest of architectural designers and homeowners in showing the roof. The roof no longer just needs to have design features to meet the functions of sheltering from wind and rain. The roof system made of color-coated panels can add the color of other architectural elements, and can obtain the effects brought by the wide-ranging changes of roof panel spokes and joints.

The slope of the roof of the color-coated board building is steep, with a typical value of 3:12 or even higher, which is good for the rapid drainage of rainwater. Roofs with small slopes are not easy to see. Generally, aluminized zinc light panels are used. For roofs with slopes less than 1/4: 12, it is more economical to use aluminized zinc light panels. Facts have proven that after 20 years of use, they still maintain excellent performance.

Roof panels are usually placed on a frame instead of directly on the comb. The frame can be made of wood or steel. Paper or similar materials are usually placed between the roof slab and the part. The color-coated roof is designed to directly contact the roof structure. The roof slab is usually flat, and small longitudinal ribs can be used to improve strength and molding. Fasteners or concealed clips secure the steel plate to the frame, and the roof panels are stacked or welded together longitudinally.


Building panel manufacturers can provide color-painted wall panels of different shapes in a wide range, and the appearance and required building effects of wall panels in all areas of the wide front can be completely consistent. The high-quality painted steel plate can ensure the consistent color and appearance of the steel plate throughout the project.

Similarly, because the same materials can be used to minimize the connection and transfer technical problems, the parts that have a key impact on the overall design effect can use the same materials, colors and processing methods for large-area exterior parts.
