Do You hope your product has been used for 20 years without any problems?:
The answer is YES for sure!!
A customer bought our product 17 years ago and continued to buy it this years . The usage picture is as follows:

Compared with the left (2023new) and right (completed in 2006),
there is no problem after nearly 20 years of construction.


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.

Successful case:
Using for Public Buildings
It has higher requirements for color retention, chalking resistance, and surface quality. Therefore, we usually adopt an AZ150 galvalume sheet, Z275 galvanized sheet, or aluminum-manganese-magnesium alloy sheet as the base metal. The top coating is commonly PVDF coating or HDP coating, 25μm in thickness and mostly in a light color. And the paint is applied by double coating and double baking.


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

Below let's review how to choose prepainted steel for different uses.

Residential Buildings

Color coated steel is often used as roofing or wall panel for residential buildings, including civil residences, villas, guard boxes, interior decorations, army barracks, and other fields. These buildings are mainly in the living area. When selecting color coated steel, it should be beautiful, natural, interesting, and personalized. That's why custom pattern printed steel, such as wood grain, brick grain, marble grain, etc., has been more and more applied to interior and exterior decoration of civil buildings.

Prefab Houses

The prefab house is mainly used in construction sites as temporary offices, dormitories, and storage rooms. When choosing color coated sheets, practicality and cost will be more important while ensuring safety. As a temporary building, it is recommended to use ordinary color coated steel, with a galvanized sheet as substrate (common zinc layer thickness). Using PE coating as top paint, with a thickness of 15-20μm, will be a cost-effective option.

General Industrial Plants

The use environment of general industrial plants and warehouses is not corrosive. When choosing color coated steel, it requires more practicability and cost-effectiveness, rather than higher corrosion resistance and aging resistance. Therefore, PE color coated steel is the most widely used in general industrial plants and warehouses. It adopts galvanized sheet as substrate with a double-sided zinc layer of 80 GSM, and the top paint thickness is 20μm. Of course, you can also lower or improve the quality requirements of the pre-painted steel according to your budgets and specific industries.

Chemical Plants

Unlike general industrial plants, chemical plants, chemical tanks, and other chemical projects are highly corrosive. Chemical products are prone to produce highly corrosive volatile substances, such as acid or alkali. It is easy to form acid or alkaline dewdrops on the surface of the color plate when exposed to water. Then the acid or alkaline dewdrops will corrode the painting, and further corrode the zinc layer and even the base metal. It is recommended to use PVDF or HDP coated steel sheets, and the ideal thickness of the top painting is 20-25 μm, with Z275 galvanized sheet or AZ150 galvalume sheet as substrate.
 

Steel Mills or Power Plants

Non-ferrous metal smelting factories, steel mills, power plants, etc., are also highly corrosive. Because coal combustion produces a large amount of corrosive media, such as sulfur dioxide ,which is easy to corrode steel plates. So the color coated steel used in these industries requires high corrosion resistance. It is generally recommended to use PVDF or HDP coated color steel. Besides, the zinc layer on double sides of the substrate is no less than 120 GSM, and the paint thickness (top/back) is no less than 25 μm/15 μm.

Textile/Electronic Workshops

Static is dangerous in industries such as clothing, textiles, electronics, instruments, medical facilities, etc., which may lead to safety accidents. Therefore, the color coated steel used in these workshops should be anti-static. The painting of antistatic color steel is with special conductive pigments. The anti-static steel is able to prevent dust from adhering and it is easy to clean. In terms of substrate, it is recommended to use galvanized steel with a zinc layer not less than 80 GSM, and the top coating thickness is not less than 20 μm.

Arched Roofing Sheets

Arched roofing sheets are mainly used in stadiums, trading markets, exhibition halls, warehousing, and other fields. Due to the arched roofing with no beams, and no purlins, but a large space span, it requires high-strength color coated panels. According to the span of the arch roof, it is recommended to use a base metal with a yield strength of 280-550 Mpa. The recommended code includes S280GD+Z - S550GD+Z. And the zinc layer thickness is not less than 120 GSM. The coating structure is generally double-coating and double-baking. The face painting thickness is not less than 20 μm. While the painting can be PVDF or HDP or PE according to your budget and the use environment.
