Two Popular Types of Aluminum Sheets 8X4
4x10 aluminum sheets (4 feet wide by 10 feet long, approximately 1.22m x 3.05m) are highly favored by buyers due to their adaptability, minimizing splicing losses while meeting the needs of large-scale construction.
1. Black 4x10 Aluminum Sheets
The "black" color of the black aluminum sheet 4x10 isn't simply spray-painted; instead, it's achieved through two main processes: roller coating or anodizing.
Roller coating: Black paint is evenly transferred to the aluminum sheet surface using a precision roller and then cured at high temperature. This process offers advantages such as a more uniform coating thickness (within ±5μm), a smoother surface, and high production efficiency, making it suitable for mass-production customization of large-sized aluminum sheets. It also offers excellent weather resistance, maintaining stable color after 5-15 years of outdoor use, and resisting fading and peeling.
Anodized aluminum sheet: An electrochemical reaction forms an oxide film on the aluminum sheet surface, which is then injected with black dye. This aluminum sheet features a finer texture with a slight metallic luster. The oxide film bonds tightly to the aluminum sheet, offering enhanced corrosion resistance. It's suitable for interior decoration (such as background walls and display cabinet panels) or humid environments (such as kitchen countertops and bathroom ceilings).
2. 4x10 Patterned aluminum sheet
The pattern significantly increases the friction of 4x10 aluminum sheet, effectively preventing slips even when wet or oily. For example, paving industrial plant floors with 4x10 diamond plate sheets can support the weight of equipment while ensuring worker safety. Its anti-slip properties also reduce the risk of accidents in high-traffic areas like ship decks and vehicle treads.
The patterned structure also enhances the aluminum sheet's bending resistance. At the same thickness, aluminum tread sheet is more rigid than flat aluminum sheet and less prone to deformation, making it suitable for applications requiring load-bearing or long-term stress, such as shelves in warehouse racks and stair treads for outdoor stairs.
Different patterns of 4x10 aluminum sheets are suitable for different applications:
Lentil pattern: The pattern has gentle ridges, moderate friction, and an easy-to-clean surface. It's suitable for indoor and outdoor floors (such as shopping mall corridors and community viewing platforms), and cold storage floors (it's cold-resistant and easy to defrost).
Diamond pattern: The pattern has a strong three-dimensional effect and better load-bearing performance. It's suitable for industrial workshop floors and heavy equipment base pads.
Polka dot pattern: It has a high aesthetic value and moderate slip resistance. It strikes a balance between decorative and practical features. It's suitable for indoor stair treads and gym floors.
