As a manufacturer specializing in the production of aluminum trim coil, BCM Alu’s 24 in x 50ft bright white aluminum trim coil, relying on mature alloy formulations and coating processes, demonstrates significant advantages in the fields of architectural decoration and protection. The core of this product is made of 3105 series aluminum-manganese alloy, treated in the H24 temper, with a thickness precisely controlled within the 0.019-0.024 inch range. The surface is coated with a bright white polyester (PE) or fluorocarbon (PVDF) coating, conforming to the RAL 9003 signal white standard. This not only meets stringent aesthetic requirements but also achieves a balance between protection and processability.

From a material perspective, the selection of 3105 series aluminum-manganese alloy is the core guarantee of the aluminum trim coil's performance. Compared to pure aluminum, the addition of 1.0-1.5% manganese increases the material strength by more than 20% while retaining excellent formability. 3105 aluminum can easily achieve complex processing such as 2T bending and is suitable for on-site bending machine processing of various irregularly shaped components. The H24 temper cold-work hardening treatment further optimizes the material's hardness and toughness ratio, ensuring the product is not easily deformed during transportation, installation, and long-term use. 3105 h24 aluminum achieves a pencil hardness of 2H, providing excellent scratch resistance.

For the coating process of aluminum trim coil, BCM adopt high-temperature baking and curing technology, with a PE coating thickness of no less than 18μm and a PVDF coating thickness of no less than 25μm. After 1000 hours of ASTM B117 salt spray testing, no significant corrosion was observed. After 5000 hours of QUVA ultraviolet aging testing, the color deviation ΔE was ≤3. The PVDF coating offers a 25-30 year warranty, while the PE coating has a warranty period of 8-15 years, making it fully suitable for harsh environments such as coastal high-salt-spray and high-altitude strong ultraviolet radiation.

The bright white surface design not only matches the minimalist aesthetics of modern architecture but also possesses practical energy-saving characteristics. White aluminum trim coil has a visible light reflectance of 84%, which can reduce the building surface temperature by 10-19℃ in summer, effectively reducing indoor cooling energy consumption, making it particularly suitable for large-area applications such as roofs and exterior walls. Meanwhile, the coating employs a chromium-free passivation pretreatment process, complying with the EU RoHS directive, and the aluminum is 100% recyclable, meeting environmental protection requirements. The aluminum trim coil's standard 24-inch width and 50-foot length specifications can be precisely cut to meet actual needs, reducing material waste. The weight of a single roll is controlled between 26-33 pounds, facilitating on-site handling and construction, significantly improving installation efficiency.

The core advantages of 24 in x 50 ft bright white aluminum trim coil are fully demonstrated in specific application scenarios.

Firstly, in the construction industry, it is a preferred alternative to traditional materials. Whether for residential eavestruments and weatherboards, or for commercial building curtain wall edging and window sills, its lightweight characteristics greatly reduce structural load and installation difficulty. Its standard 24 inch width, through precise slitting and roll forming, can efficiently produce various standard or custom profile sections. The bright white color not only blends perfectly with modern architectural styles, but its high reflectivity also contributes to building energy conservation. Compared to materials requiring on-site cutting, welding, and painting, using prepainted trim coil significantly shortens the construction cycle, reduces on-site work, and minimizes waste generation.

Secondly, it excels in durability and economy. Aluminum's inherent corrosion resistance, coupled with a robust surface coating, allows finished products to easily withstand rain, snow, salt spray, and temperature variations, resulting in a lifespan of decades. From a total life-cycle cost perspective, its low maintenance requirements (virtually no repainting needed) and long service life provide homeowners with exceptional long-term value. Furthermore, aluminum is a 100% recyclable green material, aligning with today's mainstream trend of sustainable development.

In summary, the 24 in x 50 ft bright white aluminum trim coil achieves a balance of aesthetics, protection, and workability through precise material proportions and stringent process control. Whether for detailed beautification in residential renovations or system protection for large buildings, this product offers customers an economical and reliable solution thanks to its stable performance and long service life—a core commitment we, as a manufacturer, make to product quality and application value.
