Description

Material and Structure

A2-grade aluminum corrugated sheets are crafted from premium aluminum alloy thin plates. Alloys like AA1100H24, boasting an aluminum purity of nearly 99.9%, and AA3003H24, with 97% aluminum and 3% manganese content, are commonly utilized. The manganese addition in AA3003H24 effectively fortifies the sheet's structural integrity. Through a rolling procedure, flat aluminum alloy plates transform into a corrugated profile. This distinctive wave-shaped structure not only adds visual appeal but also enhances mechanical performance. Wave heights span from 15mm to 50mm, with 15mm, 25mm, 35mm, and 50mm being typical. Wave pitches generally range between 100mm and 300mm, including popular measurements such as 115mm, 150mm, 200mm, and 250mm. Thicknesses of these sheets usually vary from 0.6mm to 2.0mm, with 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, and 2.0mm being the most prevalent. As for lengths, they can be tailored to project needs, while standard lengths often include 2000mm, 3000mm, 4000mm, and 6000mm, and common widths are 900mm, 1000mm, and 1200mm.

​Key Features

Fire Resistance

The most notable feature of A2 - grade aluminum corrugated sheets is their excellent fire - resistance. Meeting the A2 fire - rating standard, these sheets are non - combustible materials. In the event of a fire, they only emit a small amount of smoke, providing valuable time for evacuation and fire - fighting efforts. This high - level fire - safety performance makes them ideal for use in buildings where fire protection is of utmost importance, such as hospitals, schools, and public buildings.

Lightweight

Aluminum is inherently lightweight, and these corrugated sheets are no exception. Weighing only about three - tenths of steel, they significantly reduce the load on buildings. For example, when used as roof panels, they can be up to 20 kilograms lighter per square meter compared to asbestos cement tiles. This lightweight nature not only simplifies transportation and installation but also reduces the overall structural requirements of the building, potentially leading to cost savings in construction.

Aesthetic Appeal

A2 - grade aluminum corrugated sheets offer a wide range of aesthetic possibilities. They come in various colors, including the natural silver - white of aluminum, as well as numerous other vibrant hues achieved through surface treatments. The corrugated pattern itself adds a dynamic and modern touch to the building's appearance. The waves on the sheet create an interesting play of light and shadow, enhancing the visual appeal of the structure. Whether used for the exterior walls or roofs, these sheets can transform the look of a building, giving it a contemporary and stylish appearance.

Corrosion Resistance

Aluminum has a unique property of forming a thin, dense, and self - healing oxide film on its surface when exposed to air. This oxide film acts as a protective layer, shielding the underlying aluminum from corrosion. As a result, A2 - grade aluminum corrugated sheets have superior corrosion resistance compared to ordinary steel. They can withstand the harsh conditions of the atmosphere for more than 20 years without significant degradation. If further treated with chemical or electrochemical oxidation processes, the oxide layer can be thickened, extending the service life of the sheets to over 60 years. This makes them suitable for use in coastal areas, industrial zones with high pollution levels, and other environments where corrosion is a concern.

Mechanical Strength

Despite their lightweight, A2 - grade aluminum corrugated sheets possess considerable mechanical strength. The corrugated structure distributes stress evenly across the sheet, enhancing its load - bearing capacity. They exhibit good seismic performance, which is crucial in regions prone to earthquakes. The sheets can resist deformation under normal external forces, ensuring the durability and stability of the construction. Their strength also allows for longer spanning capabilities, reducing the need for frequent support structures and thus simplifying the construction process.

Ease of Fabrication and Installation

Aluminum is a highly malleable metal, and A2 - grade aluminum corrugated sheets can be easily fabricated to meet specific project requirements. They can be cut, bent, and shaped without significant difficulty, allowing for custom designs. During installation, the sheets can be quickly and efficiently installed. The reduced number of joints due to their lengthwise application further speeds up the installation process, saving both time and labor costs. Additionally, they are compatible with a variety of fastening and supporting systems, making them a flexible choice for different construction projects.

Applications:

A2 - grade aluminum corrugated sheets have a wide range of applications in the construction industry. In commercial buildings such as hotels, restaurants, and shopping malls, they are commonly used for exterior wall cladding and roofing, adding both aesthetic value and functional benefits. For industrial buildings like factories, warehouses, and power plants, these sheets are used for roofing and wall protection due to their durability, corrosion resistance, and fire - resistance. They are also suitable for public buildings such as schools, hospitals, and airports, where fire - safety and long - term durability are essential. Moreover, they can be used for architectural features like sunshades, canopies, and decorative facades, showcasing their versatility in modern construction.

In conclusion, A2 - grade aluminum corrugated sheets combine fire - resistance, lightweight, aesthetic appeal, corrosion resistance, mechanical strength, and ease of installation, making them an outstanding choice for a variety of construction and industrial applications. Their ability to meet high - performance requirements while enhancing the visual and functional aspects of buildings has solidified their position as a top - tier construction material.

Safety-Centric Packaging & Logistical Compliance

We start by carefully enveloping each panel in high-quality protective film to protect its surface. The panels are then placed into custom-made wooden crates, which are clearly marked for easy identification. To prevent any movement that could lead to damage, we fill the remaining space in the crates with cushioning substances. When it comes to shipping, we offer a selection of services, from regular to express, to meet different project deadlines.
