How many types of outdoor decking are there? Advantages, disadvantages, and pricing for each type.

Outdoor decking needs to meet seven key characteristics to ensure durability and aesthetics: good weather resistance, mold and mildew resistance, slip resistance, high load-bearing capacity, colorfastness, ease of cleaning, and low heat absorption. These requirements stem from the fact that outdoor decking is directly exposed to environmental factors such as rain, sun, and other external forces.

Below is a summary table of 5 outdoor decking materials, along with their reference prices and advantages and disadvantages.

What are the characteristics of outdoor decking?

Outdoor flooring is an area directly exposed to the environment, therefore the flooring material needs to have the following 7 characteristics to ensure durability and aesthetics:

1. Limit the impact of weather: The material needs to withstand sun and rain well to minimize warping, cracking, and maintain long-term durability.
2. Anti-mold: Outdoor decking is frequently exposed to water and high humidity, so the material should be resistant to moss and mold growth to keep it clean and safe.
3. Avoid slippery: The surface needs to have adequate grip to reduce the risk of slipping and falling when the floor is wet from rain or cleaning.
4. Good bearing capacity, high durability: The floor needs to be strong enough to withstand impacts and loads during daily activities, movement, or placing heavy objects on it.
5. Colorfast. The material should be able to maintain its color stability during prolonged outdoor use, minimizing fading due to sunlight and UV rays.
6. Easy to clean: The surface is less prone to dirt and easy to clean, saving cleaning time and maintaining its aesthetic appeal.
7. Low heat absorption: In sunny areas or near swimming pools, materials that absorb less heat will help keep the floor cooler and more comfortable to walk on.

For outdoor flooring, materials with a non-slip surface should be prioritized. R10 - R11, stable weather resistance from 5 to 10 years, and choose a structure with good drainage to minimize slipperiness during rain. According to architect Huynh Anh Tai, a member of the Vietnam Construction Association.

What are the differences between the 5 types of outdoor decking?

Laminate flooring

This material line currently has two popular forms: bars and traysPlastic wood decking is primarily used in outdoor areas including swimming pools, parks, gardens, rooftops, balconies, etc. It is one of the new and popular outdoor flooring materials in Vietnam.

Plastic wooden floor bars

Wood-plastic composite panels

Thanks to the application of modern manufacturing technologies and a standardized raw material composition (55-60% wood powder, 30-35% plastic powder, and 10% additives), wood-plastic composite has gradually replaced older building materials. The material is produced with pre-finished colors and surface textures. When installed, it does not require painting, polishing, or anti-moth/waterproofing treatments like natural wood, saving time and initial maintenance costs.

With the double-layered wood-plastic composite, an additional surface protection layer of polymer (0,1 – 0,8mm) is applied, which helps to:

1. Enhanced surface durability
2. Prevent cracking and mold
3. Increase material lifespan by up to 20 years.
4. A wide variety of colors and wood grain patterns.

The 2D wood grain printed surface on single-layer plastic Laminate flooring (without a polymer protective coating) may fade or discolor over time when exposed to UV rays and prolonged high-intensity sunlight.

Solid Laminate flooring

Natural Laminate flooring is highly durable and has beautiful wood grain patterns.This material is coated with an additional UV layer, giving the floor a beautiful shine and enhancing its scratch resistance. Whether in a modern or classic style, natural Laminate flooring is always beautiful and highly valued. Currently, there are 5 popular types of natural Laminate flooring, including:

1. Laminate flooring South Africa
2. Cam Xe wooden floor
3. Oak wooden floor
4. Walnut Flooring
5. Chiu Liu wooden floors

Natural Laminate flooring is highly valued for its ability to limit heat absorption, providing a comfortable feeling when walking and engaging in outdoor activities. This material has good mechanical durability and a lifespan of 15-50 years.

However, due to the long growth cycle of trees (20-35 years), the supply is limited, leading to high investment costs. Furthermore, most types of natural wood are susceptible to termites and weather damage; only a few species are well-adapted to outdoor environments.

Paving stones, with their natural beauty and variety of types such as granite, marble, quartz, and sandstone, are often used for paving pathways and gardens. This material is highly valued for three advantages:

1. High aesthetics: Each stone has a unique pattern, adding a touch of elegance and a connection to nature to the space.
2. Long term durability: It has good load-bearing capacity, resists wear and tear or fading, and has a lifespan of up to 50 years. It adapts well to harsh weather conditions. Natural stone can withstand temperatures of 1.210℃ – 1.260℃, while artificial stone can withstand temperatures of 70℃.
3. Avoid slippery: Outdoor paving stones have a textured surface to increase friction and ensure safety when walking on them.

Stone flooring is expensive because it is quarried from nature. The material is heavy, so the installation process is time-consuming and requires a professional team.

Paving stones are popular in garden paving projects, parks, and high-end outdoor areas. Common sizes for outdoor paving stones are 30 x 30cm, with a thickness of 3-8cm, and prices ranging from 1.110.000 to 4.440.000 VND/m² depending on the type (updated November 2025).

Outdoor paving tiles are specialized tiles designed for exterior areas such as gardens, balconies, walkways, and swimming pools, with thicknesses ranging from 10 to 15mm. These tiles have five key characteristics:

1. Good waterproofing: With a water absorption rate of less than 0,5%, the tiles do not crack due to thermal expansion and contraction, making them suitable for humid outdoor environments.
2. Avoid slippery: Tiles with a textured surface help prevent slips and falls. For family living spaces, a slip resistance rating of R10-R12 is suitable and safe for the elderly and children. For swimming pool areas, tiles with a higher rating of R12-R13 should be chosen to ensure safety, as the surface is frequently wet.
3. High load-bearing capacity: The surface hardness (PEI) typically reaches levels 4-5, capable of withstanding heavy traffic and friction, making it suitable for parking lots or high-traffic areas. The tiles can withstand temperatures from -20°C to +70°C without deformation.
4. Design variety: Outdoor tiles come in a variety of patterns, including wood-look and stone-look designs, as well as modern solid colors.
5. Easy to clean: The matte or textured enamel surface makes cleaning easy.

Non-slip outdoor garden paving tiles

In areas with direct sunlight, the tile surface can get hotter at midday, so even wearing thin sandals can sometimes feel uncomfortable. When it rains or the floor is frequently damp, some types of tiles with overly slippery surfaces may reduce grip, and the grout lines are also prone to accumulating dirt or light moss over time if not cleaned regularly.

Therefore, when choosing tiles for gardens, balconies, or walkways, prioritize those with appropriate roughness/slip properties, easy to clean, and suitable for the weather conditions of the area.

High-quality tiles, especially specialized anti-slip tiles, are usually more expensive than regular tiles. The current price of floor tiles ranges from approximately 150.000 to 700.000 VND/m² depending on the type (updated November 2025).

Aluminum flooring with PE plastic coating

PE-coated aluminum composite panels are manufactured from 6063 aluminum alloy. With a long, bar-like structure, this material consists of two main layers:

1. Aluminum core layer (1,2mm thick) Its role is to bear the load, helping to stabilize the structure and limit deformation under mechanical stress and harsh environmental conditions.
2. PE plastic surface layer It enhances shape stability under mechanical stress, reduces surface heat absorption, and supports electrical insulation for the entire material.

Aluminum flooring offers the perfect combination of metal durability and the elegant beauty of modern architecture, suitable for both residential and public buildings such as shopping malls, schools, hospitals, and airports, with:

1. Long lifespan of 15-20 years, even in areas directly exposed to sun and rain.
2. Highly aesthetic, with a realistic 3D embossed wood grain surface, the color only fades by 5-10% after the first 5 years and remains stable thereafter.
3. The PE layer reduces heat, prevents overheating, provides impact resistance, and offers good electrical insulation.
4. Weighing only 7-10 kg/m², it's quick to install and easy to clean.
