Walking on busy business streets in major cities today, you will easily be attracted by stores with shiny, luxurious facades and colorful signs. Behind that modern and durable beauty, accounting for more than 80% is Alu material. So what exactly is Alu? Why has it become the “common language” of the advertising and exterior decoration industry? Before deciding to invest money in a facade or making a business sign, learning carefully about Alu panels will help you make the best choice, optimizing costs and long-term efficiency.
What is Alu Panel (Aluminum Composite Panel)?
To understand it thoroughly, we need to start from its scientific name. Alu panel is the abbreviation for Aluminum Composite Panel. In the construction industry in Vietnam, it is often called aluminum and plastic alloy cladding panels.
Basically, this is an artificial material with a “sandwich” structure – meaning a combination of two outer layers of aluminum and a plastic core in the middle. This unique combination results in an ultra-light material that possesses the strength of metal, excellent corrosion resistance and extreme flexibility. Currently, Alu panels are widely used as a perfect alternative to traditional materials in the construction industry, interior and exterior decoration and especially in the field of advertising construction.
Classification of popular Alu panels on the market
Understanding what Alu is is not enough, you need to know how to classify it so as not to fall into the situation of “using a scalpel to kill chickens” – causing waste, or using the wrong type leading to rapid deterioration of the building.
Classified by space used
This is the most important classification that customers need to pay attention to:
- Indoor Alu (PET): This type has a thinner aluminum thickness (usually from 0.06mm to 0.1mm), the PET coating has good color fastness in sheltered environments. The advantage is that the colors are extremely diverse, the price is cheap, and they are suitable for making partitions, showroom decorations, and indoor signs.
- Outdoor Alu (PVDF): Designed to “fight” the weather. PVDF paint layer and larger aluminum thickness (from 0.21mm or more). It is resistant to UV rays, can withstand acid rain and harsh sunlight without fading or becoming brittle. This type is specialized for building facades and large-scale outdoor signs.
Sort by features
- Standard Alu: Uses regular PE plastic core, meeting basic decorative needs.
- Fireproof Alu: The plastic core is mixed with special additives, capable of self-extinguishing or preventing fire spread. This is a mandatory requirement for high-rise buildings, commercial centers or areas requiring strict fire protection standards.
Some popular Alu brands in Vietnam
- Alcorest: A “national” brand in Vietnam with a wide dealer network, stable quality and reasonable price.
- Trieu Chen (Trieu Chen): Taiwanese brand famous for its unique color palette, especially the mirror color codes and very realistic wood grain colors.
- Vertu, Alotopes: Segments from cheap to high-end, providing diverse choices for moderate budget projects.
Outstanding advantages make Alu the “king” of materials
It is no coincidence that when it comes to advertising construction, people immediately think of Alu panels. This material possesses advantages that are rarely replaced by any other material:
Timeless durability
Alu is resistant to corrosion and environmental impacts such as rain, sun, dirt or even mild chemicals. The lifespan of an outdoor Alu facade can be up to 10 – 20 years if constructed properly.
Diverse colors and aesthetic effects
From basic monochrome colors to special colors such as: gold mirror Alu, silver scratch, imitation marble, imitation wood… Alu allows architects and design units to freely create without aesthetic limitations.
Light weight, flexible construction
Although it looks very sturdy, Alu is much lighter than steel or solid aluminum. This helps reduce the load on the project. In particular, construction workers can easily cut, bend, and slot grooves to fill in column corners, creating round and arc shapes with ease.
Sound and heat insulation ability
Thanks to the plastic core structure in the middle, Alu panels have the ability to reduce noise and temperature from outside to inside the building. This is a factor that helps save energy for the air conditioning system in the summer.
Practical applications of Alu materials
With its superior characteristics, Alu appears in every corner of life:
In the advertising industry (Application No. 1): Alu is used as a sign background (Alu facade), used to process Alu embossed letters, make embossed light boxes, large advertising panels along national highways.
In construction and architecture: Facade cladding for office buildings, car showrooms, banks, convenience stores. It helps hide the defects of brick walls and gives a luxurious, modern look.
In interior decoration: Making office partitions, ceiling tiles for public buildings (train stations, airports), making kitchen cabinets, cosmetic display cabinets…
3 Important notes when choosing to buy and construct Alu facades
To have a beautiful and durable Alu facade construction project, you should not just look at the cheap price. Please note the following 3 technical factors:
- Choose the right thickness: Distinguish between “sheet thickness” (usually 2mm – 4mm) and more importantly “aluminum layer thickness” (0.06mm – 0.21mm…). Large outdoor signs are required to use a thick layer of aluminum so that the Alu panels do not blister (screw the panels) under the influence of temperature.
- Strong iron frame system: No matter how good the Alu plate is, if the welder welds the iron frame too thin or the bone spacing is too sparse, the sign will easily be dented and shaken when exposed to strong winds.
- Skill of the construction worker: The most difficult step when making Alu is applying silicone glue to the seams connecting the panels. Highly skilled workers will use straight, even, sharp glue lines, ensuring the highest aesthetics and absolutely preventing rainwater from seeping inside the iron frame causing rust.
To summarize, Alu panels are the perfect intersection between the mechanical strength of metal and the flexibility of plastic. This is the optimal solution for those who are looking for a material that is both beautiful, durable, and reasonably priced to renovate their business facade.
