Product Deep-Dive: Why 3105 Rules Bus Interiors

1. Alloy DNA

   • 0.6 % Mn + 0.5 % Mg → 35 % stronger than 1100, 30 % cheaper than 5052

   • Zero crack after 180° roll-form

2. 25 μm PE Armor

   • High-gloss polyester, 40+ RAL colors

   • 3 000 h QUV, ΔE < 1.0

   • Anti-graffiti: permanent marker wipes off

3. Extra-Wide Magic

   • 800–2 650 mm in 1 mm steps

   • One coil = one full side wall, zero seam

4. Feather-Light

   • 0.8 mm = 2.2 kg/㎡ → 40-seat bus = 880 kg total interior
