AA3003 Prepainted Aluminum Coil for Guard Bar

1. Product Overview

3003 prepainted aluminum coil is a premium aluminum-manganese alloy coated coil specially customized for guard bar production. Based on 3003 H14/H18 alloy substrate, it adopts high-quality PE, SMP or PVDF environmental coating through continuous roller coating process. The product integrates lightweight, excellent corrosion resistance, superior formability and stable color performance. It is the ideal raw material for processing highway guard bars, landscape guardrails, isolation barriers and safety protection fences, perfectly adapting to long-term outdoor harsh working environments.

3. Core Advantages

Superior Anti-corrosion & Weather Resistance

• The 3003 aluminum-manganese substrate features inherent rust-proof performance. Matched with high-performance PVDF/PE coating, it effectively resists UV radiation, rain erosion and atmospheric corrosion, with a service life up to 10–20 years, no fading or peeling for outdoor guard bar use.

Lightweight & High Structural Stability

• Low density of 2.73g/cm³, 35% lighter than steel guard bar materials. It reduces overall structural load and transportation cost, while maintaining moderate tensile strength to ensure the impact resistance and stability of guard bars.

Excellent Processing Formability

• Good ductility and coating adhesion, supporting bending, stamping, rolling and cutting without coating cracking or falling off. It is fully adaptable to various guard bar shaping processes and improves production efficiency.

Uniform & Durable Surface Finish

• Adopts continuous roller coating technology with smooth, flat and uniform surface color. It has strong color fastness, scratch resistance and no color difference, ensuring consistent appearance of finished guardrails.

Eco-friendly & Low Maintenance

•  The material is recyclable, pollution-free and meets environmental protection standards. The compact coating surface is dust-proof and easy to clean, requiring almost no daily maintenance after installation.
