Pre-painted coils use cold-rolled strip steel, galvanized strip steel (electric galvanized and hot dip galvanized) as the substrate, after surface pretreatment (degreasing and chemical treatment), with the method of roll coating, coated with one or more layers of organic coating, after baking and cooling of the plate. It is mainly used in construction (outdoor) workshops, agricultural warehouses, residential prefabricated components, corrugated roofs, household appliances, etc.
Advice for Pre-painted Coils Storage
Many people think that color steel coil storage is very simple, and do not need to pay attention to what problems, in fact, not. If you do not pay attention to storage, it will cause damage to the color plate, resulting in casualties, very serious. The storage of color steel coil is an important link to ensure the quality of the color spraying plate, due to improper operation, there will be scratches, indentation, corrosion, and other defects in the storage process, to minimize the production of these defects, the following gives some points for attention when storage.
1. If you do not use the color-coated coil for a long time, people should do a good job of storage work, if the storage will cause damage, the color-coated coil should be stored in a clean natural environment to prevent corrosion of various corrosive media. Color rolls should be stored in dry, naturally ventilated indoor air, to prevent outdoor storage or storage in the prone to condensate and temperature changes. The road surface of the storage site should be smooth, free of hard blocks, and have sufficient load capacity. The vertical steel coil should be placed on the eraser pad, wood pad, and fixing bracket, and the buckle should face upward. To avoid crowding injury, generally do not carry out palletizing storage, storage strictly limits palletizing height.
2. The physical properties of the color coating volume and some coating characteristics, such as pencil hardness, T-bend value, and impact power, will change greatly with the increase of storage time, so it is recommended that users as early as possible production processing application. Storage and transportation site should have enough indoor space for elevator equipment. The storage parts of thick plate and coil steel are effectively distributed for easy access to minimize excessive movement.
