There are several aspects to consider when selecting suitable pre-coated steel coils for construction. Steel-steel plate requirements for construction (roofing and siding) can be divided into:
The selection of color-coated boards mainly refers to the selection of mechanical properties, substrate type (coating type) and coating weight, front coating performance and reverse coating performance. Purpose, environmental corrosiveness, service life, durability, processing method and degree of deformation are important factors that should be considered when selecting materials.
Choice of front coating properties
The choice of front coating performance mainly refers to the choice of coating type, coating thickness, coating color difference, coating gloss, coating hardness, coating flexibility/adhesion, coating durability and other properties.
How to choose Prepainted Steel Coil
Safety performance (impact resistance, wind pressure resistance, fire protection);
Residential performance (waterproof, heat insulation, sound insulation);
Durability (stain resistance) (ability, weather resistance and appearance retention);
Production processability (economical, easy to process, easy to maintain and repair).
What are the factors that affect the quality of steel coils?
The quality of color-coated steel coils mainly depends on the color-coated steel coil production factory, but if the processing and installation equipment and methods are improper, it will cause varying degrees of damage to the appearance and service life of the final product.
The performance indicators of color-coated steel plates include:
Base material: yield strength, tensile strength, elongation
Electroplating: coating weight, bonding strength
Coating: color difference, gloss, T-bend, impact, hardness, dustproof, heat and moisture resistance, etc.
Surface: Visible surface defects, etc.
Sheet shape: tolerances, unevenness, etc.
