5A03 aluminum sheet for noise barriers

As urbanization accelerates, traffic noise, construction noise, and life noise have become core issues that bother residents. Traditional sound barriers often face shortcomings such as rust, deformation, and short lifespan, while 5A03 aluminum sheets are redefining the new standard of “material noise reduction” with their aerospace-grade aluminum alloy and innovative acoustic structure design!

Flait Aluminum supplies 5A03 aluminum sheets, which are widely used. Among them, high-speed rail/high-speed sound barriers mostly use 1-3mm thick, H14/H16 state sheets to optimize noise reduction and fatigue resistance. At the same time, we support customized production: support non-standard sizes (such as extra-wide 2650mm or extra-long 16000mm) to meet the needs of different engineering layouts. Click to Order

• 1. The “silent code” of 5A03 aluminum sheets: more than just metal, but also acoustic engineering

◆ Multi-layer noise reduction black technology

5A03 aluminum sheets adopt a composite structure of “honeycomb interlayer + damping coating + microporous sound absorption”, which can directionally block 20-40dB medium and high frequency noise (such as tire friction, mechanical vibration), and match customized filling materials to achieve accurate filtering of full-band noise.

◆ Anti-corrosion “longevity gene”

The scientific ratio of magnesium and manganese elements gives it super weather resistance: no brittle cracking at -30℃ extreme cold, no rust in coastal salt spray environment for 50 years, and a lifespan of more than 3 times that of galvanized steel sheets, and a 60% drop in maintenance costs throughout the life cycle.

• 2. Lightweight revolution: making sound insulation projects more efficient and low-carbon

◆ 5A03 aluminum sheet weighs only 6.8kg per square meter, and the vertical construction efficiency is increased by 50%, which is particularly suitable for rapid installation in complex scenes such as viaducts and subways.

◆ 100% recyclable, production energy consumption is 45% lower than traditional steel, helping to add points to green building certification (LEED/BREEAM), and creating a “breathing” environmentally friendly sound barrier.

• 3. Scenario-based solutions: from urban arteries to living cells

◆ Traffic trunk lines: modular splicing of highway sound barriers, wind pressure resistance of 12 levels, noise reduction coefficient NRC ≥ 0.85;

◆ Smart community: with landscape greening design, customized imitation wood grain and stone texture, to achieve “invisible noise reduction”;

◆ Industrial plant: combined with ventilation and heat dissipation needs, create an “acoustic-functional integration” enclosure system.

Specifications of 5A03 aluminum sheet for noise barriers

• Thickness selection:

◎ The common thickness of the sound barrier aluminum sheet is 1-3mm, which can not only meet the noise reduction needs, but also ensure the structural strength and wind pressure resistance performance of 135. Special environments (such as coastal typhoon-prone areas) may use thicker specifications to enhance corrosion resistance and tensile strength.

• Material state:

◎ 5A03 H state (such as H14, H16) is more common, providing a balance of medium strength and processing performance, suitable for welding and cold processing.

◎ 5A03 O state (annealed state) is suitable for scenes that require further forming.

• Mechanical properties:

◎ Tensile strength ≥175 MPa

◎ Yield strength ≥80 MPa

◎ Elongation ≥15%, ensuring the durability of the material under dynamic loads.
