Color Coated Aluminium Strip Roll for Cable Armor

Why coated aluminium strip chosen for cable armor

The coated aluminium strip is lightweight, has excellent flexibility, high corrosion resistance, and is non-magnetic with no eddy current loss. It effectively protects cables from mechanical damage, corrosion, and electromagnetic interference, making it suitable for complex environments such as underground, coastal, and chemical plants.

The surface color coating not only further enhances corrosion resistance and extends service life but also provides a wide range of color options, balancing decorative and identification purposes. It retains the advantages of aluminum alloy—easy processing and easy laying—and compared to traditional steel tape armor, it reduces transportation and installation costs, balancing practicality and economy, making it a cost-effective choice for cable armor.

Advantages of coated aluminum strips

1. Enhanced Protection: The colored surface coating further isolates the cable from corrosive media such as moisture, acids, and alkalis. Combined with the inherent corrosion resistance of the aluminum alloy substrate, this extends the service life of the cable armor and is suitable for complex environments such as underground and coastal locations.

2. Clear Identification: Different colors correspond to different cable types (e.g., power cables, control cables), voltage levels, or applications, facilitating quick identification during construction and maintenance and improving work efficiency.

3. Decorative Fit: A wide range of color options matches the appearance requirements of cable laying scenarios (e.g., building exteriors, computer rooms, outdoor facilities), balancing practicality and aesthetics. It also helps buyers quickly distinguish product specifications, meeting the visual differentiation needs of international B2B procurement.

Packaging&shipping

The packaging and transportation of cable armor color-coated aluminum alloy strips follow relevant export standards, with the core principles of protecting the color coating, avoiding damage to the strip, and preventing moisture and corrosion. Standardized packaging methods are adopted and reasonable transportation measures are used to ensure that the products are delivered intact.

FAQ

1. What is the purpose of color coating on aluminum strip?

The color coating can:

• Improve corrosion resistance

• Enhance surface durability

• Help with visual identification

• Improve the appearance of the finished cable

• Provide additional protection during forming and storage.

2. What colors are available?

Common colors include:

• Blue

• Red

• Green

• Black

• Yellow

• Natural aluminum finish

Custom colors may also be available according to RAL color standards or customer samples.

3. What coating types are commonly used?

Typical coatings include:

• Polyester (PE)

• HDPE
  

• FEVE

• PVDF for higher weather resistance

The choice depends on the cable application and environmental conditions.

4. Does the coating affect conductivity?

The coating is mainly for protection and color identification. Since cable armor is primarily a mechanical protective layer, conductivity is usually not the main purpose. However, coating properties should still match the cable's electrical and grounding design requirements.

5. Is custom slitting available?

Yes. Manufacturers usually provide:

• Custom width

• Custom inner diameter / outer diameter

• Coil weight options

• Edge condition requirements

6.What is the standard packing method?

Typical packing includes:

• Eye-to-wall or eye-to-sky coil packing

• Moisture-proof wrapping

• Wooden pallets or wooden cases

• Export seaworthy packaging
