Color coated steel sheets are environmentally friendly building materials. How to correctly select and use them to extend their lifespan is a concern for many property owners and construction professionals. As a steel mill with full-process production, Baosteel has extensive experience in the production and use of color coated steel sheets. The "Scientific Material Selection" module provides a brief recommendation and introduction for users on the selection and use of color coated steel sheets.
The proper selection of color-coated steel sheets should consider the natural and usage environment of the building, its design life, and structural characteristics to choose the matching steel grade, specifications, coating, and film. Architects, engineering owners, and processors consider the building's safety performance (impact resistance, seismic resistance, fire resistance, wind pressure resistance, snow resistance), living performance (water resistance, sound insulation, heat insulation), durability (pollution resistance, longevity, appearance retention), and economy (cost-effectiveness, ease of processing, maintenance, and replacement). For suppliers of color-coated steel sheets, these properties should be translated into the performance of the steel sheets by the steel mill and guaranteed. The performance requirements of color-coated steel sheets mainly include the material's mechanical properties (tensile strength, yield strength, elongation), coating properties (type of coating, coating thickness, and adhesion), and coating properties (paint type, color, luster, durability, processability, etc.). Wind resistance, impact resistance, snow resistance, and seismic resistance are all related to the material's mechanical properties, of course, also to the wave shape of the colored corrugated steel sheet, the thickness of the steel sheet, span, and rafter spacing. Choosing the appropriate color-coated steel sheet, coupled with proper corrugated steel sheet design, can meet the building's safety factor while reducing construction costs. The durability, processing properties, and appearance retention of the material are largely determined by the durability of the coating and coating.

Anti-static color coated steel
Features: Antistatic polyester coating incorporates a special substance coated with TiO2 as a conductive carrier, transforming the original insulating coating into a semiconductor coating, with the surface resistance changed to 10^-6 - 10^-9 Ω/m².
, Accompanied by the installation of grounding lines for construction projects, the static electricity generated on the surface of the color coated steel sheet due to air convection and clothing friction is discharged into the earth and dissipated, preventing the coating from attracting dust and reducing its performance, as well as causing static discharge hazards. Applications: food processing facilities, biological research sites, circuit board workshops, chemical factories, etc.

Insulating Color Coated Steel
Features: Insulating color coated steel is produced by adding special reflective fillers to the paint, which enhances the reflectivity of the coating to infrared radiation, thereby reducing the surface temperature of the coating to achieve insulation. This helps in energy conservation and improved durability.
Product Illustration:
Color-coated steel
Features: Household Appliances, Food Packaging, Medical Equipment; Coating: Primarily contains Ag+; Silver ions are effective agents in nature, released as a carrier by zeolite. Penetrate the cellular bodies on the coating surface, cutting off its respiratory function. Disadvantages: High cost of silver; Lack of stability of silver ions in zeolite.

The coated surface forms a textured, uneven web-like structure with a pleasing visual effect, suitable for indoor decoration, outdoor roofing, wall panels, and villas.
Installation Precautions for Color Steel Plates
1. After the color steel panels are pressed on-site, they must be sorted and stacked, with a waterproof tarpaulin covering. In case of heavy rain and moisture, the panels must be separated immediately.
Wipe away surface moisture with a dry cloth, then stack the boards and maintain good air circulation to dry the surface.
2. To expedite the project timeline, utilize flat-bucket rope hoists to lift the bundled color panels in one go to the roof, and then divide labor manually, with particular attention required.
When handling color-coated steel coils, use dry and clean gloves. Do not drag handover steel plates and other items across the surface of the color-coated panels, on the roof surface.
Staff members must wear soft-soled rubber shoes. Before ascending the roof, mud and debris should be cleared. When walking along the roof panels vertically, walk in the grooves.
End out, install in the order from bottom to top, ensuring the joints of the flange board are facing down. Absolutely prohibited to have the joints facing up.
4. The coping board at the top of the parapet wall should have a certain slope during installation. It is prohibited for the coping board on the parapet wall to have a higher middle and lower ends.
The coping at the top of the parapet wall should be sealed with two layers of sealant and fastened with double rows of rivets.

The color coated steel coils used by Baosteel are supplied by internationally renowned paint companies, currently including 5 companies with supply qualifications for Baosteel's color coated steel products: Shanghai Zhenhua, BECKER, VALSPAR, NIPPON, and AKZO NOBEL. These suppliers have been collaborating with Baosteel for many years.
Baosteel's management of suppliers for Baosteel's color coated steel sheet coatings primarily includes the following aspects:
The paint supplier for Baosteel's color coated steel sheets must meet the relevant requirements of Baosteel's procurement supplier qualification system.
2--The paint for Baosteel's color coated steel plates must comply with Baosteel's direct factory's quality management regulations for color coated steel plate paint.
3--Baosteel conducts regular second-party audits on suppliers of Baosteel's color coated steel plate coatings.
4--All Baosteel color coated steel sheet coatings must meet the Baosteel procurement technical requirements for color coated steel sheet coatings.
All Baosteel color coated steel sheet coatings must be inspected and accepted before entering the factory.
All coatings used for Baosteel's color coated steel sheets must comply with the relevant procedures of Baosteel's color coating line.
On a micro level, the coating is a porous structure. Water in the air and corrosive agents (ions, etc.) can penetrate through the薄弱 parts of the coating, leading to underfilm corrosion, which in turn causes the coating to bubble and peel off. Additionally, even with the same coating thickness, the secondary coating is denser than the primary coating. According to foreign reports and related corrosion test results, a coating thickness of 20μm or more is required on the front side to effectively prevent the penetration of corrosive agents. Due to the different corrosion prevention mechanisms of the primer and topcoat, it is not only necessary to specify the total film thickness but also to separately require the thickness of the primer (＞5μm) and the topcoat (＞15μm). Only then can the corrosion resistance of different parts of the color-coated steel plate be balanced.
PVDF products require thicker coatings to ensure longer service life. The requirements for the backside coating vary depending on the application; for sandwich panels, only a single adhesive primer layer is required. However, for formed steel sheets, due to the indoor corrosive environment, a double coating is also necessary. The thickness should be at least 10μm.
