PE has good adhesion with galvanized steel, steel with PE can be easy to modelling, it is cheap and suitable for multiple products. Many different options can be chosen from color and gloss. In the normal condition, it has 5-8 years of corrosion protection, whereas the product life can decrease once in the highly polluted area

SMP has a longer life, but with higher costs and lower cohesion & formability, its anti-corrosion period up to 10-12 years

High molecular resin and fewer polymer branches, forming a stable bond, not easy to be photo-decomposed. This paint has high color retention, UV resistance, outdoor durability and anti-chalking performance, it has 15 years of corrosion protection

It has excellent resistance to resin degradation in long-term sunshine and high-temperature environment, excellent durability but high hardness, lasting 15-20 years of anti-corrosion

High performance in anti-corrosion and color retention. It is the highest standard paint material in building construction. Lasting 20-25 years anti-corrosion, but with high cost. There are limited color to choose from when using this paint, and only low gloss paint can be used
