Color coated steel coil is light in weight,Short construction period ,beautiful in appearance, and has good anti-corrosion performance, and can be directly processed.The steel gets coated in layers of zinc oxide as substrate because this protective metal does not as get rusty easily.on the surface,with thePE,SMP, HDP, PVDF,and other coatings.it can be used for up to 25 years.
Pre-Painted Galvanized Iron Steel, also called PPGI, and Pre-Painted Galvalume Steel, PPGL, are two different types of color coated steel. Both PPGI and PPGL are used in a wide range of industries such as construction, transportation, and the appliance industry. Galvanized steel, PPGI, is coated completely with zinc, while Galvalume steel, PPGL, is coated with aluminum, zinc, and a small amount of silicone. This provides superior corrosion resistance and durability over the typical galvanized coating. This is the biggest difference between PPGI steel and PPGL, which is the reason for the differences in many features such as weight, product life, appearance, price, and applications.

How to Decide PPGI/PPGL Coil?
1. Coating Types
When choosing a primer, you need to consider the adhesion of the primer; while for top coating, corrosion resistance and color retention will be more important.
There are four commonly used coatings, including polyester (PE), silicone modified polyester (SMP), high durability polyester (HDP), and polyvinylidene fluoride (PVDF). PE coating is of good adhesion and it is widely used as a primer.
While HDP and PVDF because of their excellent durability and color retention.
They have the best long life span: more than 25 years.
| 2. Thickness of Coating At LIYING Steel, the painting thickness is usually 18-22um. The max top paint can be 55um. Generally, the thick the coating, the better the durability. You can choose according to the use environment. For example, I need this material: Dx51d+AZ150 PVDF/HDP 30um, it may used in the sea,or chemiercal factory. If you have special requirements, please let us know. 3.The base metal steel The base metal steel commonly used consist of: Galvanized steel, Galvalume steel and Al-Zn-Mg steel.Generally, The more zinc content, the longer the service life.and the zinc coating ranges from AZ30g-AZ275g. p |

Successful case(Automobiles):
Both zinc and the aluminum zinc coating help to protect metal against rusting to prolong product service life. With PPGI, when the zinc coating corrodes, the base metal will become damaged. A galvanized PPGI sheet may last approximately 10 to 15 years.
With the aluminum zinc alloy on PPGL, the aluminum rich material will corrode slowly while the zinc rich portion will corrode preferentially. This provides added corrosion resistance over strictly the zinc coating of PPGI. PPGL can last up to three times longer than PPGI.
The PPGL surface will appear to be smoother than the surface of PPGI. Because aluminum has better adhesion properties than zinc, PPGL may not require the same pretreatment for painting as galvanized sheets require.
PPGL offers better heat resistance than PPGI, with the ability to withstand temperatures up to 315°C. Because PPGL provides improved corrosion resistance with a dense layer of aluminum the base metal is further protected against erosion. The cut edge of PPGL is less protected, however, due to the honeycomb structure of the coating which does not sufficiently protect exposed edges. A coating can be applied to these exposed edges for added protection.
Both PPGI and PPGL are used in various roofing and wall paneling applications. Because PPGL better corrosion resistance it is more suitable for harsh outdoor environments such as coastal areas with exposure to seawater. PPGL also provides excellent heat resistance which makes it a popular material for ovens and chimney pipes.
The price for PPGL is typically slightly more than PPGI due to added performance and fewer manufacturers.
