PPGI refers to pre-painted galvanized steel coil, typically fabricated from a hot-dip Al-Zn coated steel substrate. This product begins with cold-rolled steel coil as base metal, which undergoes coating with an aluminum-zinc alloy (standard composition: 55% Al, 43.5% Zn, 1.5% Si) before receiving various paint coatings tailored to customer specifications.

HUIYITM Color Coated Steel
Our color coated steel undergoes rigorous surface pretreatment including degreasing, phosphating, and chromate passivation before the roll coating application. The coated material is then baked and cooled to create the finished product. The paint coating system provides superior corrosion resistance compared to standard galvanized (GI) and galvalume (GL) products.

1). Production scheduling:

All quality details required by customers, such as (RAL)color, glossiness, paint film thickness, weight per meter, width, roll length, roll weight, package as well as tolerance and delivery time, should be clearly recorded in the production sheet.

2). Following up manufacturing:

According to the requirements of the production schedule and the workshop operation standards, the production will be completed step by step to ensure that the quantity, quality, packing and delivery time are in conformity with the requirements of the buyers and relevant international standards.

3). Quality Inspection:

All goods will be inspected after finishing manufacture, a series of tests will be carried out, such as pencil hardness test, scribing hardness (also known as scratch hardness test), cut test, coating thickness measure, glossiness measure, impact test, moisture resistance test. Survey report will be issued and presented to clients.

We ensure that all products conform to the requirements of the order and relevant international standards.
