1. Introduction
Middle East desert areas, tropical Africa and coastal areas always have terrible outdoor environments, including strong UV rays, high temperature, sandstorms and salt fog. Ordinary color coated steel will fade, peel and rust within a short time, which causes high maintenance costs for roofs, walls and simple buildings. Our UV-resistant PPGI and PPGL coils are specially made for hot and harsh weather, to extend service life for overseas construction projects.
2. Key Environmental Challenges for Color Coated Steel
Strong UV sunshine breaks ordinary paint layer, leading to color fading and chalking.
High temperature above 45℃ makes soft paint crack easily after cold night.
Wind sand scratches coating surface, exposing steel base to rust.
Sea salt fog in coastal areas penetrates coating and causes internal corrosion
3. Coating Options Tailored to Harsh Conditions
PE Polyester Coating
Low cost, suitable for temporary fences, simple workshops and short-cycle buildings in inland areas, service life about 5-8 years.
SMP Silicon Modified Polyester
Better anti-fading performance, widely used for local residential houses, stable color for daily roofing use.
HDP High Durable Polyester
Strong UV and heat resistance, the most popular material for long-term warehouse, factory and farm buildings in sunny hot regions, service life 10-15 years.
PVDF Fluorocarbon Coating
Top weather resistance, anti-salt and anti-sand, perfect for seaside cities and high-end projects, color can keep stable more than 20 years.
Substrate Compatibility
PPGI galvanized substrate (Z120/Z275g/m²): fit inland non-coastal places.
PPGL galvalume substrate (AZ150/AZ180g/m²): better heat and salt resistance, suitable for desert and coastal environments.
4. Common Specifications for Hot Climate Applications
Thickness range: 0.28mm ~ 1.5mm, popular sizes: 0.32mm, 0.35mm, 0.40mm, 0.45mm
