Sandwich Wall PPGI PPGL Iron Bobina

Sandwich Wall PPGI PPGL Bobina de ferro-Especialista em proteção de segurança para parede de sanduíche e painéis de metal de teto--Sinais de alta visibilidade + proteção militar para proteger o limite de segurança do edifício

Traffic warning printing PPGI/PPGL prepainted galvanized/aluzinc steel coil is designed for buildings with high safety requirements. It uses DX51D-DX53D high-strength substrates, and uses digital printing technology to achieve customized patterns such as reflective warning strips, arrow signs, safety slogans, etc., and is covered with environmentally friendly polyester (PE) or fluorocarbon (PVDF) coating. The product is suitable for sandwich wall panels, metal roofs, isolation guardrails, road facilities and other fields, providing dual guarantees of durability and warning functions.

Core advantages

High visibility warning design

Supports printing of safety colors such as fluorescent yellow, orange-red, blue-white, etc., with a reflectivity of ≥80% (ASTM E810 standard).

Pattern accuracy ±1.5ΔE, anti-UV fading, and color stability for 10 years of outdoor use.

Graded substrate adaptation scenarios

DX51D (yield strength ≥245MPa): general type, suitable for conventional sandwich walls and roofs.

DX53D (yield strength ≥ 320MPa): deep drawing grade, used for complex shape fences.

Military grade protection performance

Galvanized layer ≥ 85g/㎡, salt spray test over 1000 hours, resistant to acid rain and sea breeze corrosion.

Fluorocarbon coating thickness ≥ 25μm, hardness 3H, scratch and impact resistance.

Exclusive advantages of sandwich walls and roofs

Sandwich walls:

Low thermal conductivity (≤ 0.04W/(m・K)), improves building insulation performance.

Hydrophobic coating design reduces condensation risk and extends wall life.

Metal roof:

High-strength substrate resists snow accumulation and wind uplift, suitable for 760/820 corrugated sheets.

Optional fireproof coating (B1 grade) to meet fire protection needs.

Environmental protection and construction convenience

Water-based ink complies with EU RoHS standards and does not release formaldehyde.

Can be directly cold-bent, suitable for automated production lines, and construction efficiency is increased by 40%.
