5000 Series Aluminum Coated Coil for Traffic Facilities

1. Product Overview

5000 series aluminum coated coil is a high-performance magnesium-alloy coated aluminum material specially optimized for traffic facility applications. Mainly including 5052, 5005, 5754 and 5083 alloys, this product adopts high-quality aluminum substrate with PE, PVDF and other environmental protection coatings processed by advanced continuous coating technology. Different from ordinary aluminum coils, 5000 series aluminum features magnesium alloy reinforcement, delivering outstanding structural stability, salt spray corrosion resistance and outdoor weather resistance. The uniform and adhesive coating layer effectively resists ultraviolet radiation, rain erosion, dust pollution and mechanical scratch, ensuring long-term stable performance in complex road, coastal and high-humidity traffic environments. It is the preferred durable and decorative material for modern road traffic, railway and municipal traffic facilities.

3. Core Product Advantages

Superior Corrosion & Salt Spray Resistance

• 5000 series aluminum takes magnesium as the main alloying element, with no complex impurity components. Combined with double-layer protective coating, it exhibits excellent resistance to acid, alkali, moisture and salt spray erosion. It can adapt to harsh traffic environments such as coastal roads, rainy and humid areas, and industrial pollution sections, avoiding rust, peeling and deformation effectively.

Excellent Outdoor Weather Resistance

• High-quality PVDF/PE coating features strong anti-UV and anti-aging performance. It resists color fading, powdering and cracking under long-term sunlight, wind and rain exposure, maintaining stable color and flat surface for more than 10 years, perfectly matching long-service-life requirements of traffic facilities.

High Structural Strength & Good Processability

• Compared with 1000 and 3000 series aluminum coils, 5000 series products have higher tensile strength and toughness. They support bending, stamping, cutting and welding processing, and are not easy to crack or deform during fabrication, meeting the forming needs of various traffic facility shapes.

Lightweight & High Safety

• The material has low density and light weight, which reduces the overall load of traffic facilities and avoids structural overweight risks. Meanwhile, the surface coating is non-toxic, environmentally friendly, flame-retardant and wear-resistant, complying with traffic safety and environmental protection standards.

Strong Decorative & Identifiable Performance

• Supports full RAL color customization with uniform color and smooth surface. Bright and standard colors help improve the identification of traffic signs and facilities, enhancing road traffic order and safety visualization.

100% Recyclable & Low Maintenance

• The aluminum substrate can be completely recycled with low carbon and environmental protection. The compact coating surface is dust-proof and easy to clean, requiring no frequent repainting and maintenance, greatly reducing the later operation cost of traffic projects.

4. Application Scope

6. FAQ

Q1: What is the advantage of 5000 series over 3000 series?

A1: 5000 series aluminum has higher strength, better toughness and superior salt spray resistance. It is more suitable for harsh outdoor, coastal and high-corrosion traffic environments with longer service life.

Q2: PE or PVDF coating, which is better for traffic use?

A2: PE is cost-effective for conventional urban traffic facilities (5-10 years service life). PVDF features ultra-strong UV resistance, ideal for highways and coastal facilities with 10-20 years long-term service requirements.

Q3: Is customized size and color available?

A3: Yes. We support full customization of size, RAL standard colors and special traffic warning colors with matte/bright surface options.

Q4: What are your MOQ and delivery time?

A4: Small trial orders are acceptable for in-stock items. Standard orders take 7-10 working days, and customized orders take 12-15 working days.

Q5: Can it adapt to coastal high salt-spray environments?

A5: Yes. Our products pass 500+ hours salt spray tests. Magnesium alloy substrate plus anti-corrosion coating ensures excellent erosion resistance for coastal traffic projects.

Q6: Can you provide certification and test reports?

A6: We provide complete documents including quality certificates, MTR, salt spray and weather resistance test reports for project inspection and bidding.

Q7: Is the product easy to process and install?

A7: It features good ductility and processability, supporting bending, stamping and welding. Lightweight design simplifies installation and saves construction costs.
