The
hot sale prepainted color galvanized coil refers to color coated steel coil, and color coated steel coil is a steel coil with organic coating. Color steel coils are divided into single board, color steel composite board, floor board and so on. Widely used in large public buildings, public buildings, mobile panels, and integrated houses for walls and roofs.
Color steel coil features
Prepainted color galvanized coil structure building is light in weight, high in strength, good in overall rigidity and strong in deformation ability. The building's own weight is only one-fifth of the brick-concrete structure, which can withstand hurricanes of 70 meters per second, so that life and property can be effectively protected. The sound insulation effect is an important indicator for evaluating the house. The windows installed in the color steel + light steel system are all insulated glass, with good sound insulation and sound insulation of more than 40 decibels. The wall made of light steel keel and thermal insulation gypsum board is soundproofed. The effect can be as high as 60 decibels.
Problems with
low cost PPGI prepainted galvanized steel coils
1. Although the hot-dip galvanized substrate with the largest amount of building materials has a large production capacity, it lacks a good substrate such as a zinc-free flower galvanized steel coil and a zinc alloy coated steel coil.
2. The variety and quality of domestic coatings can not fully meet the demand. The high price of imported coatings reduces the competitiveness. The plastic film required for the color film of the film still needs to rely on imports. It lacks PPGI prepainted galvanized steel coil with thick coating, functionality, high strength and rich colors.
