Product Description
Introducing magnesium aluminum zinc composite panel from Leboom, China’s leading manufacturer, supplier, and factory for premium construction materials. Our Zinc Composite Panels are crafted from high-quality zinc alloy and reinforced with a unique composite core, providing exceptional strength, durability, and versatility for both commercial and residential projects.
Engineered to withstand extreme weather conditions, these panels prevent deformation and discoloration, making them an ideal choice for façade applications, cladding systems, and roofing solutions. Easy to install and low-maintenance, our panels are available in a wide range of sizes, textures, and colors—offering architects and designers maximum creative flexibility without compromising performance.
This system comprises Insulated composite panels manufactured in a factory setting by bonding Class A fire-rated insulation material with metal faceplates using adhesives. The panels provide integrated thermal insulation and decorative functions. The steel sheets used include Aluzinc/Mg-Al-Zn alloy coated steel sheets, stainless steel sheets, etc.
Aluzinc panels are highly workable — suitable for folding, bending, perforation and profile forming. Standard fastening/rainscreen attachments apply; for insulated versions follow manufacturer guidelines for thermal bridging and vapor control.
● Excellent Color Stability & Weather Resistance: Superior color consistency with over 20 years of weather resistance without fading. A self-cleaning nano-coating helps maintain a bright and beautiful finish for an extended period.
● Lightweight with High Strength: The panels are thin yet offer high flexibility, strength, and are lightweight. The weight can be as low as 20kg per square meter, significantly reducing the building load and greatly minimizing the risk of detachment.
● High Malleability: The metal panels possess excellent plasticity. They can be designed and custom-formed through sheet metal bending to create various special-shaped panels according to the facade structure requirements.
● Simple Installation: The installation process is straightforward and can proceed under almost all climatic conditions, except for the most severe weather. On-site assembly is achieved using a simple "three-step method".

Magnesium aluminum zinc composite panel integrated board combines super strong corrosion resistance and efficient insulation performance, making it more durable than ordinary metal panel integrated board, especially suitable for harsh environments such as humidity and coastal areas. It can be classified into five categories:
The panel is coated with aluminum zinc magnesium alloy (containing aluminum, zinc, magnesium and other elements) to form a dense protective film. Its salt spray resistance is 5-10 times that of ordinary galvanized sheet, and it is not easy to rust or corrode when used in coastal, high humidity or industrial pollution areas.
The aluminum zinc magnesium coating has strong adhesion, scratch resistance, and wear resistance. It is not easy to fade or peel off even after long-term exposure to ultraviolet and acid rain environments. The overall service life can reach more than 30 years, which is twice as long as traditional color steel plates (10-15 years).
● The steel plate substrate (usually 0.8-1.5mm thick) has high strength, strong impact resistance and wind pressure resistance, and is not easy to deform or damage even in extreme weather such as strong wind and rainstorm, so it is suitable for the use of high-rise building exterior walls.
● The finished board is lightweight (about 15-22kg/㎡), only one-third of the weight of the integrated stone board, significantly reducing the load-bearing capacity of the building and minimizing safety hazards such as wall cracking and collapse.
Thermal insulation core materials (commonly XPS, PU, rock wool, etc.) are pre compounded with aluminum zinc magnesium steel plates in the factory without on-site splicing gaps, avoiding the traditional "metal plate+separate insulation layer" thermal bridge effect. The energy-saving rate can easily reach over 65%, and some core materials (such as PU) can meet the high energy-saving requirements of 75%.
The core material is tightly integrated with the panel, and there will be no hollowing or peeling of the insulation layer during long-term use, ensuring long-term stable and controllable building energy consumption.
The panel supports multiple surface treatment processes, such as color coating, wood grain transfer printing, stone grain transfer printing, etc., and can present various appearances such as metallic color, imitation wood, imitation stone, etc. The color is uniform and there is no color difference, which can adapt to different architectural styles such as modern, industrial style, and new Chinese style.
The board size can be customized (with a maximum width of up to 1.2m), supporting irregular processing, and can meet the exterior wall decoration needs of different scenarios such as commercial complexes, factories, residences, and public buildings.
The integrated panel is a finished board, and there is no need to install a separate keel on site (some lightweight systems can be directly bonded and fixed). Only "bonding+anchor assisted fixing" is required, which improves construction efficiency by more than 50% compared to traditional metal curtain walls and shortens the construction period by 40%.
The panel is resistant to dirt and easy to clean, and only needs to be rinsed with clean water to remove dust in daily life; If there is partial damage, a single board can be replaced separately without the need for extensive renovation, and the maintenance cost in the later stage is more than 60% lower than that of stone and tile integrated boards.
● Coating customization: Depending on the degree of environmental corrosion, high magnesium coatings (Mg content ≥ 2%) can be selected to enhance corrosion resistance;
● Pattern customization: supports compression processing (such as corrugated and trapezoidal) to enhance the overall strength of the board, suitable for large-span factories;
● Size customization: Extended panels can be customized according to the height of the factory building.
● The client provides a project environment report (such as humidity, corrosive substance content) and factory drawings to clarify customization requirements;
● The technical team recommends suitable coating and insulation solutions, and provides a quotation and technical parameters within 3 working days;
● After the customer confirms, sign the contract, pay a 30% advance payment, and the factory purchases raw materials;
● During the production process (cycle 8-12 working days), each batch undergoes coating thickness and insulation performance testing;
● Before leaving the factory, the product undergoes impact and salt spray resistance tests, and after passing the tests, it is delivered and on-site installation and debugging services are provided.
