What is Composite Decking
Bend composite decking is an outdoor decking board that is molded from traditional straight composite decking boards into a curved or arched shape. It is processed through a special hot-bending process. This technique allows the decking material, which would otherwise only lie flat, to form smooth curves.
Bending composite decking creates a more designer and artistic deck space. In addition, wood decks cannot be bent. This is because wood decks do not maintain their structural integrity when heated.
Benefits of Bend Composite Decking
Bending composite decking not only enhances the aesthetics of your deck but also increases practicality and comfort. Here are the benefits it can bring to you:
Provide a Unique Visual Effect
Bending composite decking can give a deck a unique aesthetic appeal. As curves are softer than straight lines, this allows them to blend in perfectly with the garden, pool, or natural landscape.
Curved decks are also more premium than traditional square decks. A curved staircase, seating area, or edge can be the highlight of a deck. It adds an overall sense of spatial hierarchy. Therefore, bend composite decking is particularly suitable for modern style design.
Enhance Safety and Comfort
Bend composite decking can reduce sharp edges and corners. This can effectively reduce the risk of bumping. Therefore, it is especially suitable for families with elderly people and children. In addition, bend composite decking can adapt to irregular terrain. If your yard has slopes, rocks, or a special layout, a curved deck will fit better into this terrain.
You can also use bend composite decking to divide different areas of your deck. For example, using a curved design to divide dining areas, lounging areas, and walkways is both aesthetically pleasing and convenient.
Increase Property Value
Bending composite decking enhances the curb appeal of a home. High-quality composite decking maintains long-term stability even after bending. A well-designed bend composite decking can greatly increase your property value.
Steps to Bend Composite Decking
Generally speaking, bending composite decking requires the following steps:
Prepare Tools and Materials
Before you start, you need to prepare the tools and materials used in the process. This mainly includes the following:
- Heat gun or heating blanket
- Heat-resistant gloves and goggles
- Measuring tools such as curved rulers and thermometers
- Clamps and support systems
Selection of Suitable Composite Decking
Not all deck materials can be bent. Some composite decking tends to crack when heated and bent. Therefore, consult the manufacturer to select a composite decking material that is designed for bending. EVODEK can provide composite decking that supports the heat-bending process.
Measurement and Planning
Proper measurements are the key to creating a successful decking project. Mark the location of the curves according to the deck design plans. Use a curve ruler to take measurements. Take care to allow for an error cushion when measuring. In addition, the composite deck’s framing should be adapted to the curved design.
Checking and Cleaning The Composite Deck
Before starting heating, carefully inspect the surface of the composite deck for defects. It is important to prevent breakage or deformation during the heating process. In addition, you should clean the surface of the deck from dust and contamination to prevent affecting the heating effect.
Heating The Deck Material
Use a heat gun or heating blanket to heat the decking material. Take care to maintain a temperature range of 200°F to 300°F. Excessive heat can cause discoloration or delamination of the deck surface. You can start at a low temperature and gradually increase the temperature to evenly heat the target area. This will prevent uneven bending or breakage.
Shaping and Cooling Fixation
After heating, gently bend the boards to a predetermined curvature. This process requires patience and precision. Be careful not to use too much force when bending the deck. Generally, different brands and models of decks have different minimum bending radius requirements. Refer to the product manual for specific values. Forcing the deck to bend beyond the minimum radius may result in cracking or delamination of the boards.
Next, you can use wood or metal molds to assist in shaping. In addition, it is important to shape the sheet quickly after heating to avoid cooling it too quickly and causing deformation.
Installation and Maintenance
Install the cooled bend composite decking on a pre-fabricated support frame. Generally speaking, quality bent composite decking will not break even after bending. However, incorrect installation or prolonged stress on the deck may also lead to deformation of the deck. Therefore, you should also clean and inspect the bending area regularly after the installation.
Possible Problems
Bending composite decking sounds easy. But you should also pay attention to the following points that you may encounter:
Warping and Cracking
Warping and cracking are frequent problems that occur during processing. This usually occurs because of uneven heating temperatures or too rapid cooling. Therefore, heat the composite decking slowly so that it is heated evenly. Be careful not to press too hard during bending. In addition, cools naturally after bending. Do not cool it by spraying water or other methods to prevent breakage.
Delamination
If the composite decking material you use is of poor quality, delamination may occur when bending. To prevent this, choose a professional composite decking brand such as TimberTech or EVODEK. Follow the bending radius provided by the manufacturer when machining. Additionally, using a proper support system during cooling can also be effective in preventing delamination.
Overheating Damage
Excessive heating temperatures may cause composite decking to melt or discolor. Therefore, the temperature needs to be strictly controlled throughout the processing. You can use a thermometer for real-time monitoring. The usual operation is to gradually increase the temperature starting from a low temperature and keep the temperature not to exceeding 300°F.
Deformation
The wrong operation may also lead to deformation or twisting of the composite deck. Typically, this is caused by inadequate support during bending or cooling. Therefore, make sure that your support molds hold the plates securely. In addition, do not remove the clamps until the bent composite decking has cooled completely.
Design Inspiration for Bend Composite Decking
The unique aesthetics of bend composite decking make it adaptable to many modern styles of deck design. Here are some of its design ideas:
Incorporate Natural Curves
You can have the edge of your deck follow the contours of your garden or pool. This allows your deck to blend in with the landscape. It also highlights your greenery and gives the outdoor space a more natural look.
Create an Elegant Curved Staircase
Using a bend composite decking at the entrance can give a striking look. An attention-grabbing curved staircase can add elegance to the entire garden and deck. Then pair the deck with recessed lighting to create a cozy outdoor space with a modern feel.
Design a Circular Lounge Area
You can also create a cozy gathering space with bend composite decking. Simple zoning is done through the bend composite decking. Create a curved bench around a fire pit or dining table. This is not only creative but also improves the utilization of space.
Conclusion
Bending composite decking through hot bending technology will add a unique artistic touch and functionality to the deck. Its outstanding visual appeal and adaptability make it an ideal choice for high-end decking projects. If you want a deck that is both aesthetically pleasing and functional, bent composite decking is certainly a worthwhile investment.
