Aluminum Roofing Coil 3003 H16

Aluminum roofing coil 3003 H16 is an aluminum alloy commonly used in the construction industry, particularly for the decoration and protection of roofs and walls. 3003 aluminum roofing coil belongs to the aluminum-manganese alloy family, so it has good corrosion resistance, it is one of the most common used roofing materials.

The following is a detailed description of aluminum roofing coil 3003 H16:

– Chemical Composition

The main components include aluminum (residue), manganese (1.0%-1.5%), silicon (0.6%), copper (0.05%-0.2%), zinc (0.1%), and iron (0.7%). This gives it excellent formability and corrosion resistance.

– Mechanical Properties

Tensile Strength: 170-210 MPa.

Yield Strength: 150 MPa.

Elongation: Depending on the thickness of the sheet, the elongation ranges from 1% to 2%.

– Temper

H16: Indicates cold-worked aluminum, exhibiting a certain strength and hardness.

– Specifications

Thickness: Common thicknesses range from 0.5mm to 2.5mm, with custom thicknesses available based on project requirements.

Width: Common widths include 1000mm, 1200mm, and 1500mm, and can be customized upon request.

Length: Customizable upon request, with common lengths including 2000mm, 2500mm and 3000mm.

Surface Treatment: 3003 H16 aluminum roofing coil can undergo a variety of surface treatments, such as coating and anodizing, to enhance its corrosion resistance and aesthetics.

Performance Characteristics of Aluminum Roofing Coil 3003 H16:

– Corrosion Resistance:

Due to its manganese content, it offers excellent corrosion resistance, particularly in atmospheric and freshwater environments, approaching the corrosion resistance of industrial pure aluminum.

– Workability:

It exhibits excellent formability and can be cold-worked through bending, stamping, and other processes, making it suitable for various complex roof shapes. It also offers excellent weldability and can be joined using common welding methods such as argon arc welding and resistance welding.

– Strength and Hardness:

The H16 grade indicates that the sheet has undergone a certain degree of cold work hardening. Its hardness and strength are higher than those of grades like H14, meeting the strength requirements of roof structures while maintaining a certain degree of toughness.

– Lightweight:

Aluminum’s low density makes 3003 H16 aluminum roofing sheet relatively lightweight, making it easier to handle and install, while also reducing the overall weight of the building.

Aluminum roofing coil 3003 H16 is widely used in roofing projects in the construction industry, such as industrial plants, stadiums, exhibition halls, airport terminals, and other large buildings. It can also be used for the roofing of some residential buildings that require corrosion resistance and aesthetics.

Due to its excellent corrosion resistance, lightweight properties, and wide application adaptability, 3003 H16 aluminum roofing coil has become one of the preferred materials in modern construction and industry.
