When building construction or large scale decoration, prepainted galvanized coil(ppgi coil) may be used. What is ppgi coil? The ppgi coil has good corrosion resistance, and is easy to process and transform. It is lighter than other materials, so the ppgi coil will receive great attention in the construction market.
The ppgi coil is applicable to many fields, including construction, household appliances and transportation. In the construction field, because the coated steel coil of color coated plate has light weight, beauty and corrosion resistance, it is widely used to build roofs and walls of industrial and commercial buildings such as steel structure plants, warehouses, freezers, etc. In the field of household appliances, ppgi coil are used to produce the surfaces of refrigerators, microwave ovens and other household appliances. In terms of transportation,ppgi coil are used in the production and processing of oil pan, automobile interior parts, etc.
The ppgi coil uses the color coated steel coil with the galvanized steel coil/plate as the base coil/plate. In addition to the zinc protection, the organic coating on the zinc layer plays a covering and isolation role to prevent the steel coil/plate from rusting. Its service life is longer than that of the galvanized steel coil/plate. It is reported that the service life of the coated steel plate is 50% longer than that of the galvanized steel coil.
However, in different regions and different parts of use, the service life of prepainted galvanized coil with the same zinc content, the same coating and the same coating thickness will be very different. For example, in industrial areas or coastal areas, due to the effect of sulfur dioxide gas or salt in the air, the corrosion rate is accelerated and the service life is affected.
