Composite decking & accessoriesCreate a durable, low-maintenance outdoor space with our range of composite decking and accessories. From composite decking boards to recycled plastic joists and supporting components, LL Plastic supplies everything you need to build a long-lasting decking system for gardens, patios and outdoor spaces.
Composite decking provides an attractive alternative to traditional timber decking, combining a contemporary finish with excellent resistance to the conditions that outdoor surfaces face throughout the year.
Our composite decking boards are designed for long-term outdoor use and offer several practical advantages over traditional timber:
This makes composite decking an excellent choice for garden decks, patios, terraces and other outdoor living areas where appearance, durability and easy maintenance are important.
A long-lasting deck depends on more than the boards you can see.
The supporting structure underneath is equally important, which is why we also supply plastic decking joists and subframe components designed to create a durable foundation beneath your decking.
Unlike timber joists, recycled plastic joists won't rot through prolonged exposure to moisture, helping create a decking system designed for longevity from the ground up.
Browse our Plastic Decking Joists to find the right subframe solution for your project.
Our range of decking accessories helps you complete your installation with compatible components designed for a secure and professional finish.
Whether you're replacing an existing timber deck or creating a completely new outdoor area, you can combine the appropriate decking boards, joists and accessories to create a system suited to your individual project.
From smaller garden seating areas to larger terraces and outdoor entertaining spaces, composite decking provides a practical way to create an attractive outdoor surface without the regular maintenance associated with traditional timber.

Composite decking boards offer a durable, attractive and low-maintenance alternative to traditional timber decking. Designed for outdoor living, composite decking can be used to create everything from compact garden seating areas to large terraces and entertaining spaces.
One of the biggest advantages of composite decking is simple: you can achieve an attractive timber-inspired finish without the regular painting, staining and treatment associated with traditional wooden decking.
At LL Plastic, we supply composite decking boards alongside the joists, fixings and accessories required to build a complete decking system.
A garden deck spends its entire life exposed to changing weather conditions. Rain, moisture, sunlight and temperature changes can all take their toll on traditional outdoor materials.
Composite decking boards are manufactured specifically for outdoor use and offer a number of practical advantages:
For homeowners who want to spend more time enjoying their garden and less time maintaining it, these characteristics make composite decking an attractive alternative to timber.
Timber remains a popular decking material, particularly because of its natural appearance and relatively low initial cost.
However, wooden decking generally requires ongoing maintenance to help preserve its appearance and condition. Depending on the timber and installation, this can include cleaning, staining, painting or applying protective treatments.
Composite decking requires considerably less routine maintenance.
There's no need to regularly stain or paint the boards, and the material won't splinter in the same way as deteriorating timber.
Although composite decking prices can therefore be higher initially, it's worth considering the cost and time required to maintain a deck throughout its entire lifespan rather than comparing the purchase price of the boards alone.
The colour and finish of your decking can have a major impact on the overall appearance of your garden.
Different composite decking colours can complement different properties and landscaping styles. Darker finishes can create a contemporary appearance, while natural timber-inspired shades can work particularly well alongside traditional gardens and properties.
Before choosing your decking, consider:
Remember that your decking will form a significant visual feature within the garden, so it's worth considering how the complete area will work together rather than choosing the boards in isolation.
The boards are only one part of a long-lasting deck.
Underneath every decking installation is a subframe, and the material used for that structure can have a significant effect on the longevity of the overall system.
This is particularly relevant when using long-lasting composite decking. Installing durable boards over a conventional timber structure can leave the supporting joists vulnerable to moisture and eventual deterioration.
For this reason, LL Plastic also supplies Plastic Decking Joists manufactured from solid recycled plastic.
Unlike timber, recycled plastic joists won't rot through prolonged exposure to moisture, helping create a durable foundation underneath your composite decking.
When planning your project, consider the lifespan of the entire decking system — not simply the boards you can see.
Correct installation is essential for the appearance and long-term performance of composite decking boards.
The exact installation requirements will depend on the decking system you're using, so you should always follow the relevant installation instructions.
Important considerations can include:
Composite materials naturally expand and contract as temperatures change, making the correct spacing particularly important.
LL Plastic provides installation guidance for relevant products to help ensure your decking is fitted correctly.
Using the appropriate composite decking fixings helps create a secure installation and professional finish.
Depending on the decking system, specialist clips or hidden fixings can reduce the number of visible screws across the finished surface while maintaining the required spacing between boards.
LL Plastic supplies decking accessories alongside our boards and structural components, making it easier to source the products required for a complete installation from one supplier.
One of the biggest attractions of composite decking is how little ongoing maintenance it requires.
For general dirt and debris, regular sweeping combined with occasional cleaning using warm soapy water and a soft brush will be sufficient for many installations.
It's good practice to:
Avoid aggressive cleaning methods or chemicals unless they're specifically approved for your decking, as these could affect the surface finish.
Although garden terraces are the obvious application, composite decking boards can be used to create a variety of outdoor spaces.
Popular applications include:
Composite decking can also be incorporated into multi-level garden designs, helping connect different areas and elevations while creating a consistent finish.
LL Plastic supplies both composite and recycled plastic products, and there are differences between the two.
Composite decking is generally chosen where customers want the appearance and finish associated with contemporary garden decking combined with relatively low maintenance.
Fully recycled plastic decking boards can offer another option where maximum resistance to moisture and extremely low maintenance are priorities.
The right material therefore depends on the application, appearance you're trying to achieve and the requirements of the individual project.
If you're unsure which option is right for you, speak to LL Plastic and we can help you compare the available systems.
The best decking projects aren't designed by considering the boards alone.
A complete system should consider:
Decking boards → fixings → joists → supporting structure → drainage → installation.
Combining durable composite decking boards with a moisture-resistant recycled plastic subframe can help create an outdoor area designed for long-term use with significantly less maintenance than a conventional timber system.
