Coated steel sheets possess excellent decorative properties, fingerprint resistance, strong coating adhesion, and the ability to maintain vibrant colors for extended periods. They have become an ideal composite material for industries such as home appliances and building materials. However, different industries choose different base materials based on their needs. The differences between home appliance and building material base materials are as follows:
Difference 1: Home appliance coated steel sheets typically use electro-galvanized and cold-rolled steel sheets as the base material, used in refrigerators, freezers, wine cabinets, large air conditioner units, dryers, bread makers, etc. Different PVC/PET films and their base materials and thicknesses create a rich variety of wood grain patterns, patterns, solid colors, marble patterns, sheepskin patterns, orange peel patterns, and hundreds of other patterns to choose from.
Difference 2: Construction coated steel sheets typically use hot-dip galvanized steel sheets and hot-dip aluminized zinc steel sheets as the base material. Hot-dip galvanized steel sheets have many uses in construction. To further improve the corrosion resistance of hot-dip galvanized steel sheets, prevent the zinc layer from directly contacting the air, and increase surface colorability, a coating is required. In other words, depending on the intended use, it is necessary to select appropriate substrates and color films, and adopt suitable lamination methods to produce laminated steel sheets that meet the requirements. The environmental requirements for use dictate that laminated steel sheets must have good solvent resistance, acid and alkali resistance, pollution resistance, and heat resistance, and their fire resistance rating must also meet standards. These requirements should be given sufficient attention.
