Aluminium Composite Material (ACM) is a popular three-layer composite sheet used in building materials. The sheet is made up of a plastic core layer with aluminium on both sides. The outer layer of the product has a decorative and protective coating. In recent years, ACM building materials have grown in popularity due to their modern, sleek appearance.

ACM materials have gained popularity in the construction sector over the last few decades. Designers love the variety that these materials offer and prefer to use them in their creations. While all ACM sheets will have a thin layer of aluminium, there are two choices for the core material. The first material is Polyethylene (PE). ACM panels that use PE cores are more affordable and lighter, making them a popular choice for buildings that are up to two stories tall.

For larger buildings, builders are opting for more specialised fire-retardant cores. While fire-resistant cores are more expensive, new fire safety requirements may necessitate the use of these panels in multi-story constructions.

Aluminium Composite Material (ACM) panels come with different fire-resistant ratings. B1 is the common rating for most ACM panels. However, not every plastic aluminium composite panel is fireproof, and the fire-resistant performance is determined based on the non-combustibility grade. There are four types of non-combustibility grades; B1, B2, B3, and A2. B3 is the lowest grade with a flammable raw material rating, while B2 is classified as a combustible building material. Therefore, when choosing a fire-resistant material for your building, it is crucial to consider the product's fire rating feature.

• A2 fire protection rating is for non-combustible construction materials that are difficult to burn.
• B1 classification is for flame and fire-retardant building materials that have good flame and fire-retardant properties. When the material comes into contact with an open flame in the air or is exposed to high temperatures, the fire will not spread quickly. Once the fire source is removed, the combustion will stop as quickly as possible.
• B2 is the third fire-resistant performance class for flammable materials. These substances have unique fire-retardant properties. When exposed to a fire in the air or a high temperature, they will ignite, causing the fire to spread, similar to wooden columns, beams, staircases, and trusses.
• B3 classification for construction materials is the least efficient in terms of fire safety. They are flammable materials that do not have any fire-retardant properties. As a result, they are regarded as flammable and dangerous and are the worst choice for building claddings.

Aluminium Composite Material (ACM) is popularly used in curtain walls, exterior wall decorations, advertising, and interior wall decoration. It's essential to note that the specifications of the building material vary depending on its intended use.

• ACM for Building Curtain Wall: When using ACM for building curtain walls, the top and bottom aluminium panels must have a minimum thickness of 0.50mm, and the total thickness must be at least 4mm. Typically, aluminium sheets from the 3000 and 5000 series are used, and it should be coated with fluorocarbon.
• ACM Material for Indoor Use: In most cases, upper and lower aluminium panels used for indoor purposes are made of an aluminium plate with a thickness of 0.20mm and a minimum thickness of 0.10mm, with a total thickness of 3mm. The coating is either polyester or acrylic. Additionally, ACM can also be utilised in airplanes, cabinets, and automobiles.
• ACM Materials for Exterior Wall Decoration and Advertising: For exterior wall decoration and advertising, the top and bottom aluminium panels should be rust-resistant and have a thickness of at least 0.20mm, and the total thickness should be at least 4mm. A fluorocarbon or polyester coating is typically used.

• Rigidity: Compared to a single-layer aluminium plate, the aluminium-plastic composite panel features a higher elastic limit, is more resistant to bending, and can maintain good flatness performance naturally over an extended period without requiring excessive external force.
• Lightweight: ACM is composed of aluminium and a small-density plastic core material, making it smaller and less hefty than other metals with the same thickness and rigidity.
• Colourful and Decorative: The layers of the aluminium-plastic panel can be manufactured in a variety of colours, and the design can be tailored to suit any application. Additionally, photocopying technology can replicate various textures, such as granite, wood grain, and metal patterns, to create a unique texture and high-quality pattern design.
• Durable: Aluminium-plastic composite board utilises a metal and core material thermal composite technology with strong bonding. The surface coatings vary based on the application environment, with fluorocarbon coatings providing superior weather resistance.
• Affordable: Pre-coating continuous coating and metal/core material continuous thermal compounding manufacturing are used in producing aluminium-plastic composite panels, thereby resulting in high production efficiency and low raw material costs. ACM is an economical alternative to typical metal veneers.
• Eco-friendly: The discarded aluminium-plastic panel contains recycled aluminium and plastic core components that have low environmental impact. Moreover, wood-aluminium composite panels and outdoor ornamental aluminium-plastic panels utilise fluorocarbon coatings, which are highly durable with low maintenance costs, resulting in low overall life cycle expenses.
• High Surface Flatness: The surface flatness of the aluminium-plastic composite panel exceeds that of a single-material metal sheet, particularly the large-sized sheet materials, owing to the continuous thermal composite production process. It has a flat and uniform appearance and is often used for architectural decoration.

To clean aluminum composite material panels, you can use a soft, damp cloth. If necessary, you can use a mild detergent. The water should be at room temperature.

Do not use harsh or sharp objects to clean the panels, as this could scratch them. If there is debris or caked-on dirt, apply water, mild soap, and a soft cloth or sponge until the dirt is removed. Avoid using anything with a bumpy texture.

Rinse the area well after cleaning, and then pat it dry. The surface should be left looking crisp.

Here are some additional tips for cleaning aluminum composite material panels:

• Clean the panels regularly to prevent dirt and grime from building up.
• If you use a detergent, make sure it is mild and non-abrasive.
• Do not use strong chemicals or solvents to clean the panels.
• If you have any doubts about how to clean the panels, consult the manufacturer's instructions.

ACM is recognised for its robustness and long-lasting performance, despite being lightweight. It is highly resilient to a variety of weather conditions, including extreme outdoor temperatures and extended exposure to the elements such as sun, wind, rain, and snow. While there is a chance of denting from flying debris during catastrophic events like hurricanes, ACM is able to withstand more damage than many other materials.

Correx is a type of extruded polypropylene sheet that is sold under a specific brand name. While it is sometimes referred to as corrugated plastic, it is different from corrugated cardboard in that it consists of a single piece with two flat surfaces and flutes, or open pipes, running through it. The thickness of Correx is determined by the size of these flutes.

Correx is manufactured using propylene ethylene copolymer, which is a type of corrugated plastic.

The production process of Correx involves the use of a molten plastic material that is forced through a metal template or die. As the plastic material passes through the template, it cools down and solidifies into a continuous sheet. The sheet is later cut into individual boards which can be printed on.

If you're confused about the similarities or differences between Correx, Corvex, Coriflute and corrugated plastic, don't worry. While these may seem like different products, they are all essentially the same thing: corrugated plastic sheets.

That being said, it's important to note that Correx is actually a brand name that has become so widespread that people use it as a generic term to describe any type of polypropylene fluted plastic sheeting. So, whether you're looking for Coriflute or Corvex, you're essentially looking for the same thing as Correx.

Yes, Correx can be recycled and it belongs to the Waste stream 5 category.

Although Correx cannot be classified as biodegradable, it will eventually decompose and fall apart with prolonged exposure to sunlight.

Correx is definitely 100% waterproof, making it an excellent option for temporary signs and outdoor advertising displays that require printing.

The temperature at which Correx begins to soften is around 144 degrees Celsius and it will completely melt at 165 degrees Celsius.

Ordinary Correx does not have fire-resistant properties. However, there are alternatives that offer flame-retardant capabilities. We recommend consulting with our team to explore these options further.

Correx is an incredibly strong material that can withstand a significant amount of force. It's especially resistant to tearing or breaking when its thickness is 4mm or greater, making it highly durable for a wide range of applications. However, it should be noted that while it can be easily bent along the flutes, it's much more challenging to bend it across them.

Correx, a corrugated plastic material, finds its applications in a broad spectrum of industries. The material's uses are determined by its thickness.

The 2mm-thick Correx variety, being the thinnest, is widely used in tray and packaging applications.

The 4mm version is the preferred choice of many printers for small outdoor signs and point of sale products that include stockist boards, safety signs, and bollard covers.

Thicker 6mm and 8mm Correx varieties find their use in creating larger signage, where their extra thickness adds to their strength.
