The packaging of color-coated steel coil is composed of (plastic film), (moisture-proof paper), (iron sheet), (side guard ring), (galvanized side guard plate), (packing tape and packing buckle), and film-coated suede from the inside to the outside. The sand surface needs to be composed of (wooden tray).
Iron and paper tubes are often used in the packaging of color-coated rolls, film-coated, suede, sand-surfaced and rolls with small friction between steel layers, thickness below 0.2mm. It is recommended to use iron The barrel prevents roll deformation.
The tests often done in the production process of color-coated coils are: substrate surface and thickness, finished product thickness, paint film thickness, hardness, impact test, T-bend test, MEK wipe, gloss test.
The main uses of color-coated steel coil are construction industry, household appliances,industry, transportation industry and so on.
The surface treatment effects of color-coated steel coil include Pattern, embossing,suede(wrinkle,matt),with film, sand surface, etc.
