032 aluminum coil stock is a lightweight and durable aluminum material with a thickness of 0.032 inches. Aluminum coil stock is easy to process, highly weather-resistant, and available in a variety of paint colors. 032 aluminum coil stock is commonly used to make gutters, channel letters, trims, trailer side panels, and shutters.
The 0.032-inch (0.81mm) thickness of aluminum coil stock strikes a perfect balance—it has sufficient strength and rigidity to meet various structural requirements while maintaining excellent ductility and lightweight properties. Its tensile strength reaches 240-310MPa, and its yield strength is 150-210MPa. It can withstand the vibration and impact of trailer travel while maintaining a smooth, crack-free surface during the bending and forming of 3D channel lettering. Compared to the thinner 0.025 inch material, the 0.032-inch aluminum coil stock offers 40% better dent resistance, and compared to 0.040 inch aluminum coil stock material, its bending radius can be reduced by 25%, significantly reducing processing energy consumption.
In addition to the standard mill finish, we BCM offer PE/PVDF pre-painted aluminum coil stocks. Utilizing internationally leading roll coating technology, we create a dense coating of 0.002-0.005 mm on the surface of 0.032 inch aluminum coils. For example, our fluorocarbon coating achieves a pencil hardness of 3H or higher and withstands over 3000 hours of salt spray testing, ensuring drainage ditches remain corrosion-free for 15 years in high-humidity coastal environments. For decorative strip applications, our developed metal brushing process creates micro-textures of 0.01-0.03 mm on the surface, producing a gradient effect in light reflection and enhancing visual depth by more than three times.
Take the commonly used 3003 H14 aluminum alloy as an example. When you specify the "H14" temper, you are actually requesting a material internal structure that has undergone specific work hardening and low-temperature heat treatment. It's not simply about "hardening," but rather precise control that increases the material's yield strength to approximately 145 MPa or higher while stabilizing the elongation at around 8%. This data is significant for you because: when rolled into the complex cross-section of gutter ditches, it provides uniform resistance to springback, ensuring consistent profile angles; when used as a trailer side panel covering a frame, its tensile strength is sufficient to withstand high-frequency vibrations during driving, rather than merely meeting static load-bearing requirements.
Customers who purchase our 032 aluminum coil stock product may used it for the following applications:
Gutters:
Aluminum coil stock are commonly used to manufacture components for drainage systems due to their corrosion resistance, which effectively extends service life.
Trims:
Used in construction and interior decoration, aluminum's luster and paintability make it an ideal decorative material.
Trailer side panels:
Due to its lightweight and strength, aluminum coil stock are suitable for manufacturing trailer side panels, capable of withstanding certain pressure and impacts.
Channel letters:
Aluminum's machinability makes it suitable for creating 3D channel letters and signage, widely used in advertising and signage production.
We understand that you are processing not only materials, but also time and yield. Therefore, our understanding of 0.032’’ aluminum coil stock must ultimately translate into production consistency. This includes:
Absolute control of thickness tolerance:
Our commitment to a tolerance zone of ±0.005 mm ensures constant die clearance during multi-pass continuous forming (such as high-speed rolling of drainage channels), preventing jamming or dimensional deviations caused by thickness fluctuations.
Intrinsic flatness of the sheet:
Through advanced rolling and stretching straightening technology, we strive to eliminate residual stress within the coil. What you get is a naturally flat sheet surface after unfolding, minimizing additional straightening steps when used as large trailer side panels or advertising lettering bases, and fundamentally eliminating later deformation caused by uneven internal stress.
Targeted preparation of surface condition:
Whether providing a standard rolled surface for subsequent painting, or supplying pre-oxidized, coated, or textured surfaces, we understand that the surface is the "skin" of your product. We ensure zero residual grease and no scratches or bright spots on the coil surface, which is crucial for coating adhesion and a flawless final appearance.
Ultimately, every 032 aluminum coil stock we deliver is a contract of reliability. It is not just a product that conforms to ASTM or GB standards, but a precisely designed engineered component that can seamlessly integrate with your equipment, molds, and process knowledge.
