Aluminum Alloy 1050 Aluminum Sheet for Road Signage (2.0–3.0 mm | Custom Width | Reflective Base Coating)

Introduction                                                

The 1050 reflective base coated aluminum sheet for road signage (2.0–3.0 mm thickness, 800–2000 mm customizable width, high-performance reflective base coating + optional color topcoat) is the global traffic engineering industry’s most reliable and cost-effective material for durable, high-visibility road signs, traffic signals and guideboards.

• Alloy 1050: purity ≥ 99.5 %, excellent flatness & coating adhesion.
• Reflective base coating: Class 1 retroreflectivity (ASTM D4956 Type XI), 20-year durability, 3000 h salt-spray.
• Custom width + protective film: ready for digital printing, plotter cutting or screen printing. Result: road signs that maintain > 80 % reflectivity for 20+ years, withstand extreme weather, and install 60 % faster than steel or galvanized sheets.
