Alu-zinc PVDF color steel tile

As a high-end roofing material, PVDF color steel tiles are widely popular in the construction field due to their unique material combination and process advantages. The following is a detailed description of its core advantages:

1. Super weather resistance

Corrosion resistance

The corrosion resistance of the galvanized substrate (55% aluminum + 43.4% zinc + 1.6% silicon) is 3-6 times that of ordinary galvanized sheets, and the salt spray test can last up to 1000 hours without rusting.

Particularly suitable for highly corrosive environments such as coastal areas and industrial areas.

Anti-ultraviolet

PVDF fluorocarbon coating (polyvinylidene fluoride) contains ≥70% fluorocarbon resin, with a UV reflectivity of up to 80%, and a 10-year color difference ΔE≤3 (almost indistinguishable to the naked eye).

2. Excellent physical properties
Performance indicators Parameters Advantages compared to ordinary color steel tiles
Wind pressure resistance level 12 (can withstand 60m/s wind speed) Safe in typhoon areas
Temperature resistance range -50℃~+120℃ Applicable to extremely cold/high temperature areas
Fire protection level A2 (non-combustible material) Passed GB8624-2012 certification
Service life 25-30 years 2-3 times that of ordinary color steel tiles
3. Intelligent surface characteristics
Self-cleaning function
PVDF coating has low surface tension, and dust can be washed away by rainwater (contact angle>90°), reducing cleaning and maintenance costs by 80%.
Application scenarios: photovoltaic roofs, airports and other low-maintenance places
Multi-color options
Using top fluorocarbon coatings such as Kynar 500 or Hylar 5000, providing 200+ standard color cards, and supporting RAL customized color matching.

4. Outstanding economic benefits

Low cost throughout the life cycle

Although the unit price is 20-30% higher than ordinary color steel tiles, the saved maintenance/replacement costs make the comprehensive cost in 5 years 15% lower.

Easy to install

Light weight (5.8kg/㎡), can be cold-bent, reduce the structural load-bearing requirements, and improve construction efficiency by 40%.

5. Environmental certification
Passed LEED green building material certification

100% recyclable (the recycling value of the substrate is 1.8 times that of ordinary steel plates)

Typical application scenarios
Industrial buildings: factories/logistics warehouses (need to be corrosion-resistant and less maintenance)

Public facilities: airports/gymnasiums (need to be high-value and long-life)

Commercial buildings: shopping centers/4S stores (need to customize colors)

Special needs: photovoltaic roof substrates/clean factories
