Contractor Spec Guide 2025 |
Anti-fingerprint (AF) stainless steel sheets cut elevator-cleaning labour by 40 % and maintain a mirror finish for >10 years. This guide gives contractors the hard data: ASTM scratch results, 5-year cost comparisons, and a hotel case study showing USD 18 k savings across 30 elevators. MOQ is only 50 sheets and sizes can be customised up to 1 500 × 4 000 mm. Download the spec sheet & warranty PDF at the end.
<!-- 1. AF COATING HARDNESS & SCRATCH TEST -->
| Test Parameter | Result | Industry Benchmark |
|---|---|---|
| Pencil Hardness | 6H | ≥4H |
| Scratch Resistance (ASTM D3363) | No scratch at 1 000 g | 500 g |
| Cross-Cut Adhesion (ASTM D3359) | 5B (0 % peel) | ≥4B |
| Taber Abrasion (CS-10, 500 cycles) | ΔHaze<2 %< /td> | ΔHaze<5 %< /td> |
Conclusion: AF nano-silica top-coat is 2× harder than standard clear lacquer, making it suitable for high-traffic elevator cars.
<!-- 2. CLEANING COST SAVINGS -->
| Surface | Clean Freq (×/wk) | Labour Min/m² | Cost USD/m²/yr* | 5-yr Cost USD/m² |
