The Manufacturing Process of Composite Decking

Raw Materials Used in Composite Decking

The manufacturing of composite decking begins with the careful selection of raw materials.

High-quality recycled wood and recycled plastic are sourced to ensure that the final product is durable and aesthetically pleasing. The wood fibre pieces often come from sawmill scraps and other wood waste, while the plastic components are typically derived from post-consumer materials like bottles and containers. This not only helps in reducing landfill waste but also contributes to a more sustainable production cycle.

Throughout the process, strict quality control measures are in place to verify that every batch meets the required standards. This is crucial to ensure the longevity and performance of the decking boards under various conditions, including exposure to UV rays, extreme heat and high humidity typical of certain areas in Australia.

Additionally, the use of advanced testing methods, such as tensile strength and impact resistance evaluations, ensures that the composite decking can withstand the rigors of daily use, making it an ideal choice for both residential and commercial applications.

Steps in Creating Composite Decking

The creation of composite decking follows several key steps:

1. Material Preparation: The wood and plastic are shredded and ground into small particles.

2. Mixing: The ground wood and plastic are mixed together, along with additives to enhance performance.

3. Extrusion: The mixture is then heated and extruded through moulds to form the decking boards.

4. Cooling and Cutting: After coming out of the moulds, the boards are cooled and cut to the desired lengths.

5. Finishing Touches: Finally, the boards may undergo a finishing process, such as sanding or the application of a protective coating.

Each of these steps is meticulously monitored to ensure consistency and quality.

For instance, during the mixing phase, specific ratios of wood to plastic are maintained to achieve the desired balance of strength and flexibility. Furthermore, the extrusion process can be adjusted to create various textures and finishes on the surface of the decking, allowing for a range of aesthetic options that can complement different architectural styles.

This attention to detail not only enhances the visual appeal of the product but also contributes to its overall performance, making composite decking a popular choice among homeowners and builders alike.

Composite Decking Boards

Once the composite boards are cut to size, they may also undergo additional treatments to further improve their resistance to moisture and mould.

Some manufacturers incorporate advanced technologies, such as co-extrusion, where a protective layer is fused to the surface of the board during the extrusion process. This results in a product that is not only more resistant to fading and staining but also easier to clean and maintain.

As a result, composite decking has gained a reputation for being a virtually no maintenance alternative to traditional wood decking, appealing to those looking for both beauty and practicality in their outdoor spaces.

Types of Composite Decking

Solid Composite Decking

Solid composite decking features a single solid core across its entire surface.

This type is robust and typically heavier than its hollow counterpart. Solid composite decking can better withstand the pressures of foot traffic and is less likely to warp or bend over time. Additionally, its dense structure makes it an excellent choice for areas exposed to harsh weather conditions, as it is less prone to moisture absorption.

Homeowners often appreciate the long-lasting nature of solid composite decking, as it requires minimal maintenance and can retain its aesthetic appeal for years.

Moreover, solid composite decking is available in a variety of colours and finishes, allowing homeowners to customize their outdoor spaces to match their personal style. Some manufacturers even offer textured surfaces that mimic the look of natural wood, providing an elegant appearance without the associated upkeep.

This versatility makes solid composite decking a popular choice for both residential and commercial applications, where durability and design are equally important.

Hollow Composite Decking

Hollow composite decking is designed with a hollow core, which provides a lightweight option that is easier to handle and install. This type is often more affordable and still delivers good durability.

However, it may not be as strong as solid composite decking, making it more suitable for areas with lighter foot traffic. The hollow design also allows for better airflow, which can help reduce moisture buildup beneath the deck, potentially prolonging its lifespan.

In addition to being budget-friendly, hollow composite decking is often praised for its eco-friendliness, as many products are made from a recycled material. This makes it an attractive option compared to traditional decking materials for environmentally conscious consumers looking to reduce their carbon footprint while enhancing their outdoor living spaces.
