Blue Color Coated Roofing Sheets

Blue color coated roofing sheets is a building material treated with a blue coating, primarily used for roof decoration and protection. Among metals used in blue roofing sheets, aluminum and steel are often used, and we are an aluminum roofing sheets supplier, blue aluminum roofing sheets is one of our key products.

Coating performance of blue roofing sheet:

– Coating Types: Common coating types include polyester (PE) color-coated and fluorocarbon (PVDF) color-coated.

Polyester color coated aluminum roofing sheets is relatively inexpensive and generally has a warranty period of around 10 years.

Fluorocarbon color coated aluminum roofing sheets offers superior performance, including improved weather resistance, corrosion resistance, and color retention, with a warranty period of over 20 years.

– Color Options: Colors can be customized based on RAL and Pantone international color charts or customer samples. The blue color palette offers a variety of shades, such as regal blue and slate blue, to meet the decorative needs of various architectural styles. Common RAL colors include, but are not limited to, the following:

RAL 5002 – Ultramarine Blue

RAL 5010 – Gentian Blue

RAL 5011 – Steel Blue

RAL 5015 – Sky Blue

RAL 5021 – Water Blue

Specifications of blue colour roofing sheet:

– Thickness: Generally ranges from 0.05mm to 6.00mm. Aluminum roofing sheet thickness typically ranges from 0.2mm to 1.5mm. Different thicknesses can be selected for different applications and structural requirements.

– Width: Coated aluminum coils typically come in widths of 20mm to 1500mm. Coated aluminum sheet lengths can be customized upon request, with common lengths ranging from 100mm to 1750mm.

Features of blue color coated roofing sheets:

– Lightweight:

Aluminum has a density approximately one-third that of steel. Blue color coated aluminum roofing sheets of the same area weighs significantly less than steel, reducing the load on the roof structure and facilitating transportation and installation.

– High Strength:

Commonly used materials, such as 3003 aluminum-manganese alloy and 3004 aluminum-magnesium-manganese alloy, enhance their strength and rigidity by adding elements like manganese and magnesium, meeting the requirements of roofing under varying load conditions.

– Excellent Corrosion Resistance:

Aluminum readily combines with oxygen in air to form an aluminum oxide film, which offers natural corrosion resistance. The color coating further enhances its weather and corrosion resistance, effectively resisting erosion from acid rain and salt spray.

– Highly Flexible: Blue color coated aluminum roofing sheets can be bent into various shapes, including straight, curved, and fan-shaped, to suit different building roofing requirements, such as spherical and curved roofs.

Blue color coated roofing sheets are widely used in industrial and civil buildings, warehouses, special buildings, and roofs of large-span steel structures, such as steel factories, airports, stadiums, exhibition halls, and warehouses. They can also be used for building wall decoration and aluminum ceilings. They are also suitable for special locations where aesthetics and corrosion resistance are paramount, such as coastal buildings and chemical plants.
