Product Description

Product Description

 

Our 5052 H32 Coated Aluminum Sheet is a premium marine-grade roofing material, crafted by applying high-quality functional coating (PE/ PVDF optional) to the surface of 5052 H32 aluminum alloy substrate through advanced roller coating, surface pretreatment, and high-temperature curing processes. As a typical 5xxx series aluminum alloy, 5052 H32 is renowned for its excellent corrosion resistance—especially its outstanding resistance to saltwater erosion, which is far superior to 1060, 3003 series aluminum alloys. The H32 temper enhances its mechanical strength, making it rigid and durable enough to withstand strong coastal winds and marine weather impacts. Combined with the protective coating, the product integrates corrosion resistance, wind resistance, wear resistance, and decorative properties, making it the first choice for roofing in marine, coastal, and near-shore areas, fully complying with the technical requirements of marine building materials.

Packaging & Delivery

 

Packaging: Each sheet is covered with a thick PE film to prevent scratches, corrosion, and saltwater pollution; the sheets are stacked neatly, separated by wooden strips, and packaged with waterproof, moisture-proof, and anti-corrosion packaging materials, suitable for sea, land, and air transportation.

 

Storage: The products should be stored in a dry, ventilated, and rain-proof warehouse, placed obliquely at an angle of 5°, with wooden strips under the bottom (spacing ≤2m) to avoid moisture, deformation, and corrosion.

 

Transportation: During transportation, avoid collision, extrusion, exposure to rain, sunlight, and salt spray; for marine transportation, additional anti-corrosion packaging is added to prevent saltwater erosion during transportation, ensuring the products arrive at the coastal project site in good condition.

 

 

FAQ

 

Q1: Why is 5052 H32 alloy more suitable for marine and coastal roofing than other aluminum alloys?
A1: 5052 H32 is a typical Al-Mg alloy, which contains magnesium and chromium elements that form a dense oxide film on the surface, providing excellent resistance to saltwater, salt spray, and humid corrosion—far superior to 1060 (pure aluminum) and 3003 (Al-Mn alloy) series. The H32 temper further enhances its mechanical strength, making it more resistant to strong winds and impact, which is precisely the core requirement of marine and coastal roofing. Ordinary aluminum alloys are prone to pitting corrosion and deformation in marine environments, while 5052 H32 can maintain long-term stability.
 
Q2: What is the difference between PE and PVDF coating for 5052 H32 aluminum sheet in marine scenarios?
A2: Both coatings are suitable for marine and coastal environments, but they differ in performance and cost: PE coating has good corrosion resistance, color retention, and cost-effectiveness, suitable for general coastal areas (such as near-shore commercial buildings) with moderate corrosion. PVDF coating has superior salt spray resistance (1500+ hours), UV resistance, and acid-base resistance, suitable for harsh marine environments (such as offshore islands, coastal industrial zones) with strong salt spray and high pollution, but the cost is higher. You can choose according to the specific corrosion level of the project site.
 
Q3: Can the product be customized according to the specific needs of coastal roofing projects?
A3: Yes, we support full customization. We can customize the thickness (0.5mm-3.0mm), width, length (up to 12m), coating type (PE/PVDF), color (according to RAL/Pantone color card), and shape (corrugated, trapezoidal, standing seam) according to the project’s design drawings, roof slope, span, and corrosion environment, to perfectly match the coastal roofing needs. We can also provide customized solutions for special marine scenarios (such as offshore platforms).
 
Q4: What after-sales services do you provide for marine and coastal projects?
A4: We provide 2-3 years of quality guarantee period (longer than ordinary commercial products). During the guarantee period, if there is any quality problem (such as coating peeling, substrate corrosion) caused by the product itself, we will provide free replacement and maintenance services. In addition, we provide professional technical guidance, including installation guidance, corrosion prevention suggestions, and daily maintenance tips, to help customers solve the problems encountered in the use of the product in marine and coastal environments. We also provide lifelong technical consultation services.
