AA5052 H38 1.5MM Channel Letter Aluminum Coil for Highway Sign

AA5052 H38  1.5MM  Channel Letter Aluminum Coil for Highway Sign

The AA5052 H38 1.5mm channel letter aluminum coil is a high-performance material specifically engineered for manufacturing durable, precision-shaped highway signage. Composed of 5052 aluminum alloy—strengthened with magnesium as the primary alloying element—this coil is processed to the H38 temper (a high-strength, strain-hardened state) and rolled to a consistent 1.5mm thickness, making it ideal for crafting robust, weather-resistant channel letters and structural components in highway signage systems.

Product Parameters

Application Scenarios

• Main Route Markers: Large-scale overhead or gantry signs indicating highway numbers, names, or route directions (e.g., interstate shields, provincial highway labels).

• Directional Guidance Signs:  Lane allocation, or interchange instruction signs, where clear, rigid lettering/symbols are essential for driver visibility.
• Warning & Regulatory Signs: Speed limit, curve warning, or construction zone signs, requiring long-term durability in high-traffic, exposed environments.
• Coastal/High-Wind Area Signage: Thrives in harsh conditions such as coastal highways (resisting salt spray) or regions prone to strong winds (e.g., bridge crossings, mountain passes), where structural integrity is paramount.
• Large-Format Signage: Supports oversized designs (over 5㎡) common in highway interchanges, ensuring minimal deformation under dynamic wind loads.
