Blue Color Coated Steel

-- Steady & Reliable Manufacturer --

Introduction

Blue Color Coated Steel is a popular choice for architectural projects requiring a strong visual statement or a specific branding match. Blues, particularly Sky Blue (RAL 5012) and Traffic Blue (RAL 5017), are frequently used for public buildings, schools, and corporate roofing. The deep color requires a high-quality paint system to ensure the vibrancy and gloss are retained over the material's lifespan, even under intense UV exposure.

We offer a wide palette of blues on both PPGI and PPGL, ensuring you can find the exact shade needed for your project's identity.

Frequently Asked Questions

Q: Are darker blue colors hotter on the roof?
A: Yes, darker colors absorb more solar radiation. While the steel itself is conductive, if thermal performance is critical, the roof must be paired with high-quality insulation (e.g., thick PU sandwich panels).

Q: What is the risk of chalking with blue steel?
A: Chalking (paint degradation) is a potential issue with dark, saturated colors if only standard PE paint is used. Choosing SMP or HDP is mandatory for dark blues to prevent premature chalking and maintain color integrity.
