DX51D+Z SGCD Color-coated Coils
PPGI is the abbreviation of Pre-Painted Galvanized, that is, pre-painted galvanized steel. Usually refers to PPGI Coil (color-coated galvanized coil), PPGI Sheet (color-coated galvanized sheet) and other steel products. It is based on galvanized coils and then covered with color coatings to give the product more Color, and this rich and beautiful surface makes it more versatile in use.

Product Description

The color-coated steel coil using hot-dip galvanized steel coil as the base material is not only protected by the zinc layer, but the organic coating on the zinc layer plays a covering and protective role to prevent the steel strip from rusting, and its service life is about 1.5 times longer than that of the galvanized coil. times.

PPGI is a galvanized color-coated steel material, which is to carry out surface chemical treatment (degreasing, phosphating, chromium hydrochloric acid passivation) on the coated steel sheet (galvanized, galvanized, nickel-plated, etc.), then apply paint, and then bake Made products. Advantages: It not only has the mechanical strength and easy formability of steel plate, but also has good decoration and corrosion resistance of organic materials. The coating has strong adhesion and can keep the color fresh for a long time. Application: Widely used in various fields such as construction, home appliances, furniture, public facilities and transportation.

Type of coating structure

2/1: Apply twice on the upper surface, once on the lower surface, and bake twice.

2/1M: Coat the upper and lower surfaces twice and bake once.

2/2: Coat the upper and lower surfaces twice, and bake twice.

Uses of different coating structures:

2/1: The corrosion resistance and scratch resistance of the single-layer back paint are poor, but it has good adhesion and is mainly used in sandwich panels;

2/1M: The back paint has good corrosion resistance, scratch resistance and processability, and has good adhesion. It is suitable for single-laminated panels and sandwich panels.

2/2: The corrosion resistance, scratch resistance and processing formability of the double-layer back paint are good, and most of them are used for single-layer laminates, but their adhesion is poor, so they are not suitable for sandwich panels.

Color-coated rolls are mainly used in modern buildings, which have good mechanical structure performance and aesthetics, anti-corrosion, flame retardant and some additional properties. Colored coil substrates can be divided into cold-rolled substrates, hot-dip galvanized substrates, electro-galvanized substrates, etc.

The main uses of prepainted rolls include:

1. In the construction industry: roofs, roof structures, rolling doors, kiosks, shutters, street waiting halls, ventilation channels, etc.;

2. Furniture industry: refrigerators, air conditioners, electronic stoves, washing machine shells, oil stoves, etc.;

3. Transportation industry: automotive ceilings, side panels, hoardings, car shells, tractors, ship partitions, etc. Among these uses, steel structure workshops, composite board workshops, and color steel tile factories are most used.

The technical requirements for galvalume and magnesium-aluminum plating are relatively high, and the products can be used in automobiles, home appliances and other fields. Color-coated rolls are widely used in large-span workshops, warehouses, office buildings, villas, roof additions, air purification rooms, cold storage, shops, kiosks and temporary housing.
