There are many types of color coated sheets. Generally speaking, in terms of common coating durability, the ranking is as follows: PVDF (Polyvinylidene Fluoride) > HDP (High Durability Polyester) > SMP (Silicone Modified Polyester) > PE (Polyester).

Different industries and environments have varying performance requirements for color coated sheets. When selecting a product, it's important to match the specific needs of each application scenario while balancing performance and budget—neither blindly pursuing the highest-end option nor compromising by choosing the wrong product to save costs. Below is a quick selection guide for common scenarios. Save it for future reference!

General Factory Buildings & Warehouses

The core requirements for these buildings are practicality and economy. The environment itself does not pose corrosion risks to the color coated sheets, so the focus should be on construction cost and usability.

Recommendation: PE polyester color coated sheets offer outstanding cost-effectiveness and are the top choice for building envelope systems in such applications.

Regions with Intense UV Exposure

In China's northwestern plateau regions, strong UV radiation can cause coating chalking and aging over time. Therefore, the key consideration is the coating's UV resistance.

Recommendation: Opt for PVDF fluorocarbon sheets, SRP (Special Reinforced Polyester) sheets, or HDP high-durability polyester sheets, which offer excellent UV and corrosion resistance, effectively extending building service life.

Chemical Industry, Coastal Areas, Steel Mills & Power Plants

The chemical industry involves strong acids, alkalis, and other corrosive substances. When these materials come into contact with moisture and adhere to the steel surface, they gradually corrode the coating—and in severe cases, attack the zinc layer and the steel itself. Coastal areas experience year-round high humidity, and chloride ions from seawater can easily penetrate thin or less dense coatings, accelerating corrosion of the galvanized layer.

Recommendation: Choose coatings with superior anti-corrosion properties. PVDF fluorocarbon sheets and HDP high-durability polyester sheets are recommended.

Cold and High-Altitude Regions

In severely cold areas such as Northeast China and the Qinghai-Tibet Plateau, long winters and extremely low temperatures pose significant challenges to color coated sheet performance.

Recommendation: Select high-performance color coated sheets such as PVDF fluorocarbon sheets or HDP high-durability polyester sheets to achieve the expected service life.

Regions with Severe Sandstorms / Mining Industry

In areas with frequent sandstorms, abrasive particles can cause scratches and gradual wear on the coating surface, reducing the steel sheet's service life to some extent.

Recommendation: Choose color coated sheets that combine corrosion resistance, scratch resistance, and wear resistance. SMP silicone modified polyester sheets are highly recommended for effectively resisting sandstorm environments.
