PPGI / PPGL

PPGI/PPGL (prepainted galvanized / galvalume coil)

Production

Alucosuper pre-painted galvanized/galvalume steel coils us a kind of high-level steel product which has good weather-resistant and fade-resistant. PVDF coating coils mainly based on coating and baking.It has distinct advantage on shortening construction period, reducing maintenance charge and recycling. Compareed with wood, concrete and other building materials, the prepainted steel is provided with distict usability and precessability, it has been one of the main building materail, and used more and more widely.

Basical Metal

The Raw material of PVDF coating for construction is cold rolling steel, hot-dipped galvanized, galvalume,electro galvanized and so on

Paintings

PVDF could be adopted by different organic coating according to the different applied enviorment. It is coated by PVDF, durability polyester and silicone modified polyester for exterior. It is coated by normal polyester for interior. There are some specical function coating, for example, antistatic, Nano, bacteriostar, heat output and absorption heat, etc, for special construction purpose.

Procession

Because the prepainted steel for construction is mainly based on two coats, the traditional two coats and bakes is the most typical production technology. It is primier coating + top coating. of course, There are other technology, as one coating, three coating. Coating structure1/1,2/1,2/2,3/1,3/2.

Take an example for two coating and two baking, the technology process is :
