Galvanized color coated coils can be used on roofs to make roof tiles and can be flattened to make wall panels. Low price for construction

1. Classification:
- By performance level: general use, mechanical bite, stamping, deep drawing, special killed steel deep drawing, non-aging ultra-deep drawing, structure and other different levels.
- By substrate type: divided into cold-rolled coil and hot-rolled pickled coil H.
- By zinc coating type and coating weight: double-sided equal-thickness zinc coating, zinc-iron alloy coating, etc., coating weight has a variety of specifications, and differential thickness coating can also be provided.
- By zinc layer surface structure: including normal zinc spangle NNS, small zinc spangle MMS, no zinc spangle FFS, zinc-iron alloy ZFZFS.
- By surface quality: divided into ordinary surface FA, higher-level surface FB, and higher-level surface FC.
- By surface treatment: passivation C, oiling O, paint sealing L, phosphating P, and untreated U.
2. Features
- Strong corrosion resistance: The zinc layer can effectively prevent steel from being oxidized and corroded, and prolong its service life.
- Good surface quality: It has good surface gloss, and the color and pattern can be customized according to needs, and the color is not easy to fade.
- Conducive to deep processing: It has good processing performance and can be cut, stamped, bent and other processing operations, which can be conveniently made into metal products of various shapes.
- Economical and practical: Compared with some other protective treated steels, the cost of galvanized coils is relatively low and cost-effective.

1. ‌Enhance corrosion resistance‌
The zinc coating can effectively prevent steel from being oxidized, especially in humid or corrosive environments, where the cathodic protection of zinc can significantly extend the service life of steel.
The zinc coating is thick and dense, which can prevent the steel substrate from contacting the corrosive solution and provide long-term protection.
2. ‌Extend service life‌
The zinc coating is firmly bonded to the steel substrate to form a zinc-iron alloy layer, which has excellent wear resistance and corrosion resistance and is suitable for various harsh environments.
Under high temperature and high humidity conditions, the zinc coating can still remain stable, significantly extending the service life of the material.
3. ‌Beautiful and decorative‌
After passivation treatment, the zinc coating can present a variety of appearances such as white, color or military green to meet different decorative needs.
The surface finish is high and can be used directly for decorative purposes without additional treatment.
4. ‌Excellent processing performance‌
Galvanized materials have good ductility and can be processed by cold punching, rolling, bending and other processing techniques without damaging the coating.
It has strong welding performance and can be well connected with other materials. It is widely used in the manufacturing of mechanical equipment and industrial parts.

Rebar is the common name for hot-rolled ribbed steel bars. The grade of ordinary hot-rolled steel bars is composed of HRB and the minimum yield point of the grade. H, R, and B are the first letters of the three words "hot rolled", "ribbed", and "bars" respectively. Hot-rolled ribbed steel bars are divided into three grades according to the new national standard: HRB300, HRB400, and HRB500.
