Utilizing a Z40 ($40g/m^2$) hot-dip galvanized substrate, these sheets provide an enhanced protective foundation compared to standard commercial grades. By integrating the globally recognized RAL Color Matching System with high-precision roll-forming technology, Bomis Steel delivers a roofing solution that ensures long-term color vibrancy and superior atmospheric resistance.
1. The Z40 Substrate: Strategic Corrosion DefenseThe Z40 zinc coating mass is specifically selected to balance flexibility with durability.
Compliant with JIS G3312 and EN 10346 standards, this substrate offers:Enhanced Sacrificial Protection: The $40g/m^2$ zinc layer provides a robust cathodic barrier, effectively shielding the steel core from edge rust and surface oxidation in moderate climates.Optimized Forming Integrity: Z40 provides the ideal surface tension for paint adhesion while maintaining a 0T-2T bend rating, ensuring no coating delamination during the rigorous corrugation process.
We utilize advanced spectrophotometer technology to ensure that every batch matches your specific RAL Classic немесе RAL Design requirements:
True-to-Spec Coloring: Whether it’s RAL 5012 (Light Blue), RAL 6005 (Moss Green), or RAL 9003 (Signal White), we guarantee a color deviation of $\Delta E \leq 1.0$.
Multi-Stage Coating System: Features a high-build primer for corrosion inhibition, followed by a 15-20μm topcoat for UV stability, and a functional back coat to prevent condensation damage.
Finish Versatility: Choose from High-Gloss, Semi-Gloss, or Matte (Texture) finishes to suit specific architectural styles.
High-Rigidity Corrugation: Our profiles are engineered with precise wave depths to maximize snow and wind load capacities, making them suitable for both wide-span industrial roofs and residential siding.
Anti-Chalking Formulation: Our paint chemistry is enriched with UV-stabilizers to prevent the white powdery residue (chalking) common in intense sunlight regions.
Efficient Installation: The uniform overlap design ensures a watertight seal, significantly reducing onsite installation time and labor costs.

We utilize advanced computerized spectrometry to match the precise pigments of the RAL Classic system. Every batch is tested to ensure a color deviation of $\Delta E \leq 1.0$. This ensures that if you order RAL 5012 (Light Blue) or RAL 7016 (Anthracite Grey) today, and reorder months later, the color consistency will remain uniform across your entire project facade.
The Z40 ($40g/m^2$) coating mass provides a 33% to 100% thicker zinc barrier than entry-level commercial grades. This extra thickness is critical for the “cut-edge” protection of the corrugated sheet. It ensures that the steel core remains protected from rust at the points where the sheet is cut or drilled during installation, significantly extending the roof’s maintenance-free lifespan in moderate outdoor environments.
Yes. We offer three primary finish options to suit different architectural styles:
High Gloss: Reflective and vibrant, ideal for commercial branding.
Semi-Gloss/Satin: The standard architectural finish.
Matte/Textured: Reduces glare and provides a premium, modern aesthetic, often used for high-end residential roofing.
Absolutely. Our Z40 substrate is engineered with a balance of ductility and adhesion. It passes the 0T-2T бүгу сынағы, which means the paint will not crack or flake even when the sheet is bent 180 degrees. This makes it perfect for producing various corrugated waves, trapezoidal (IBR) profiles, and ridge caps without compromising the protective coating.
“Chalking” is the white powdery residue that appears when paint breaks down under intense UV light. Our RAL color PPGI sheets are formulated with UV-stabilized Polyester (PE) or HDP resins. These chemical stabilizers absorb harmful ultraviolet rays, protecting the paint’s molecular structure and keeping your roof looking new for years without the dull, faded appearance common in low-grade materials.
