1. Storage and transportation of color coated plates
Storage, transportation and loading and unloading are important links affecting the quality of color-coated plates. Due to improper operation, various defects such as scratches, embossing and corrosion may occur during storage, transportation and loading and unloading, in order to minimize the occurrence of various defects. The following notes are given in some operations. Specific provisions regarding storage, transportation and handling can be consulted or consulted with experts.
The product should be stored in a dry and ventilated indoor environment, avoiding open storage and storage in places where condensation and temperature changes are likely to occur.
The color coated board should be stored in a clean and tidy environment to avoid the erosion of various corrosive media.
The ground of the storage site should be flat, free of hard objects and have sufficient load-bearing capacity.
Horizontal steel coils should be placed on rubber mats, mats, brackets, etc., and the straps should be upwards and should not be placed directly on the ground or on the means of transport.
In order to avoid crushing, the coils are usually not stacked and stored. The stacking of steel sheets should be strictly limited to the number of stacking layers, and the weight and size of the board should be placed below.
The mechanical properties of the color coated board and some coating properties such as pencil hardness, T-bend value, impact work value, etc. may change with the storage time, so it is recommended that the user process as soon as possible.
The storage site should have enough space for the lifting equipment to use.
The storage locations of steel plates and coils should be reasonably arranged for easy access and minimize unnecessary movement.
The color coated board should be transported according to the state of the factory, and the original packaging cannot be dismantled at will. A rubber pad should be added between the spreader and the product during loading and unloading to prevent bumps. If necessary, special spreaders should be used.
The carriage of the transport vehicle should be cleaned. Rubber mats or other protective devices should be placed on the floor of the vehicle. The necessary protective measures should also be taken around the carriage to prevent the package from being indented or bumped.
