PPGL Color Coated Galvalume Steel Coil - Leading Building Material Manufacturer

PPGI PPGL Color Coated Galvalume Steel Coil for Building
Prepainted galvalume steel coils used galvalume/aluzinc (AZ20 -275gsm) steel coils as the basic raw materail. After pretreatment (the surface of the basic raw materail is cleaned to remove impurities, degreasing, and undergoes composite oxidation and passivation treatment), the surface is coated with PE. SMP, PVDF paint is then baked and solidified. It is more suitable for applications in corrosive and coastal areas.

Substrate Type

1. Hot-dip galvanized steel sheet: this substrate has good impact performance and good elongation and yield value, this kind of production of color steel sheet in the construction, decoration, and other industry applications get very good evaluation.
2. hot-dip aluminum-zinc-plated steel sheet: the process of this substrate and hot-dip galvanized steel sheet process is basically similar, the difference lies in the surface of the zinc layer content is not the same, the surface of the zinc flower phenomenon is also a big difference, other aspects of the basic there is no gap, weather resistance and life is better than galvanized steel. 
3: Aluminum: the best advantage of aluminum is the special industry with, because the price itself is very high in so on the cost alone is also a small expenditure, so only special industry options: refrigeration, insulation, poisoning, sterilization, and so on industry. Impact performance: excellent, can be tangible, intangible impact, bending. 
4. Cold rolled sheet: cold rolled sheet is not annealed steel, but also galvanized steel, aluminum zinc-plated steel predecessor. This steel plate impact performance is very low, the material hardness is very high, the yield value as well as the elongation is very low, welding performance is good. 

Types of color-coating:standard polyester,matt polyester,decoprint

Product Advantages

1.It has the strength and deformation properties of a steel plate
2.Good decorative and anti-erosion properties of organic materials
3.Strong adhesion of the coating, can keep the color novelty for a long time.
