As outdoor living becomes a central element of modern home design, homeowners and contractors alike are seeking high-performance, low-maintenance, and aesthetically pleasing decking solutions. One of the most practical innovations to meet this demand is the 5m composite decking board. These extra-long boards are transforming how we design and build outdoor decks—especially in large garden spaces, commercial terraces, and poolside environments.

In this comprehensive guide, we will explore five key aspects of 5m composite decking boards, including their benefits, technical specifications, installation tips, cost considerations, and sourcing options. Whether you’re a DIY enthusiast, a professional builder, or a property developer, this article will help you decide if 5m composite decking is the right fit for your next project.
Why Choose 5m Composite Decking Boards?
The decision to use 5m composite decking boards instead of traditional shorter options like 2.4m or 3.6m boards can greatly impact the aesthetics, efficiency, and overall success of your decking project. Here’s why:
Fewer Joints, Cleaner Look
One of the most obvious advantages of using longer decking boards is the reduction in visible joints. With fewer seams running across the surface of your deck, the finished product looks more seamless, professional, and upscale. This is especially true for modern or minimalist designs where visual clutter is undesirable.
Faster and Easier Installation
Fewer boards mean fewer cuts and joints to manage. This not only speeds up the installation process but also reduces the need for additional fixings and fasteners. Whether you’re paying for labor or handling the installation yourself, 5m composite decking can save both time and money.
Better Structural Integrity
Longer boards provide increased continuity and structural consistency. There’s less room for movement or misalignment over time, which is a common issue in decks with many short boards. This makes 5m composite decking boards a great choice for high-traffic or commercial spaces that demand extra durability.
Ideal for Large Decking Areas
If you’re working with a wide or extended outdoor space—say, a large backyard patio or a commercial café terrace—using longer boards allows you to span the distance without interruptions. This can enhance both the look and the utility of the area.
Reduced Waste
With a proper layout plan, 5-meter boards can minimize cutting waste. This means not only fewer materials going to the landfill but also more efficient budgeting.
Technical Specifications and Material Advantages
Composite decking is known for combining the beauty of natural wood with the durability of synthetic materials. But when it comes to 5m composite decking boards, the technical advantages become even more pronounced.
Composition
Most composite decking 5m boards are made from a mixture of wood fibers (such as sawdust or bamboo powder) and recycled plastic. This combination results in a sturdy, rot-resistant product that can withstand environmental stressors like sun, rain, snow, and temperature fluctuations.
Dimensions and Profiles
A standard 5m composite decking board typically features:
Length: 5000mm (5 meters)
Width: 140mm–160mm
Thickness: 20mm–25mm
Profile: Solid or hollow core; grooved or smooth edge
Solid-core boards are better suited for heavy-duty applications, while hollow-core boards offer a lighter, more cost-effective option.
Slip Resistance
Most 5m boards come with textured surfaces to improve slip resistance—an essential feature for decks near pools, spas, or in rainy climates.
Fade and Stain Resistance
Premium 5m composite decking boards come with a capped surface, a protective polymer shell that offers enhanced resistance to UV rays, stains, and moisture. This makes them perfect for sun-drenched balconies or spill-prone entertainment areas.
Low Maintenance
Unlike timber, composite boards don’t require sealing, staining, or sanding. Occasional cleaning with soap and water is usually enough to maintain their appearance.
Installation Tips for 5m Composite Decking Boards
Installing longer decking boards involves a few unique considerations compared to working with shorter options. Here are some tips to ensure a successful installation:
Transport and Storage
Because of their length, 5m composite decking boards can be more challenging to transport. It’s crucial to use proper lifting techniques and ensure the boards are supported across their entire length to avoid bending or cracking during unloading.
When storing before installation, stack them on a flat surface and cover with a breathable tarp to protect from direct sun and rain.
Joist Spacing and Support
Longer boards require careful support planning. It’s typically recommended to install joists at:
400mm centers for residential use
300mm centers for commercial or high-load applications
Always check the manufacturer’s specifications, as requirements may vary slightly depending on the core structure (solid or hollow).
Expansion Gaps
Composite materials expand and contract with temperature changes. For 5m lengths, it’s especially important to leave appropriate expansion gaps—usually 5–7mm between boards and 10mm where the deck meets a wall or post.
Hidden Fasteners
To maintain the clean look that 5m composite decking boards are known for, consider using hidden fastening systems. These clip-based systems are easy to install and preserve the surface finish of your deck.
Cutting and Trimming
Despite their length, 5m boards are just as easy to cut as standard ones. Use a fine-tooth saw blade to avoid splintering. Always double-check your measurements, as replacing a cut 5m board can be more costly than a shorter one.
Price Comparison: Types of 5m Composite Decking Boards
The cost of 5m composite decking boards can vary significantly depending on multiple factors such as the type of core (solid or hollow), surface finish (capped or uncapped), brand reputation, and country of origin. Understanding the price range of different board types can help you plan your budget effectively and avoid overspending or underestimating total costs.
In general, solid-core boards tend to be more expensive than hollow-core due to their increased density and strength. Likewise, capped composite boards (those with a protective polymer shell) are usually priced higher than uncapped boards because of their superior resistance to fading, moisture, and staining.
If you’re buying in bulk—especially for large residential or commercial projects—many manufacturers offer volume discounts. It’s also worth noting that while some low-cost boards may seem attractive at first glance, they may lack quality warranties, UV resistance, or durability over time. Therefore, price should always be balanced with performance and longevity.
Below is a general price comparison table for various types of 5m composite decking boards, based on current international market averages:
| Board Type | Core Type | Surface Finish | Estimated Price per Board (5m) | Estimated Price per m² |
|---|---|---|---|---|
| Basic Hollow Composite Board | Hollow | Uncapped | $35 – $45 | $28 – $35 |
| Premium Hollow Board | Hollow | Capped | $48 – $58 | $32 – $38 |
| Standard Solid Board | Solid | Uncapped | $55 – $70 | $38 – $45 |
| Capped Solid Board (Deluxe) | Solid | Capped (UV/Anti-Stain) | $70 – $90 | $45 – $55 |
| Woodgrain Embossed Board | Solid | Capped + Texture | $85 – $110 | $50 – $65 |
| Fire-Resistant Board (FR) | Solid | Capped (FR rated) | $100 – $130 | $65 – $80 |
Note: Prices are indicative and may vary based on country, supplier, shipping, and customization options. Always confirm with your vendor whether the quoted price includes VAT, fasteners, and delivery.
When budgeting for your deck project, also consider the additional costs such as joists, subframe materials, fasteners, edge trims, and labor (if not DIY). In many cases, investing a little more upfront in higher-grade composite decking 5m boards can reduce maintenance and replacement costs later on—making it a smarter long-term decision.
If you’re unsure about which board type best fits your budget and project needs, it’s a good idea to request samples and consult with composite decking boards suppliers – Hosung WPC, who can offer tailored pricing based on your quantity and location.
Cost Considerations and Budgeting Insights
Although 5m composite decking boards may seem more expensive at first glance, they often provide better value in the long run. Here’s why:
Price per Linear Meter
Generally, the price per linear meter of longer boards is lower than that of shorter ones. You’re paying more upfront per board, but getting more coverage—often at a better rate.
Reduced Labor Costs
Fewer boards mean less time spent measuring, cutting, and fixing. This can significantly reduce labor charges if you’re hiring professionals. Even for DIYers, this means less time spent on knees and ladders.
Lower Fastener Requirements
A deck built with 5m boards requires fewer joists, screws, and clips, reducing your accessories budget.
Waste Management
Using longer boards can help you align your deck layout with minimal cutting, resulting in less leftover waste—and more efficient use of every dollar spent.
Long-Term Value
Because of their durability and low maintenance requirements, 5m composite decking boards deliver excellent return on investment. Over time, the savings on staining, sealing, and replacing damaged boards add up.
Where to Buy 5m Composite Decking Boards
Now that you’re convinced of the benefits, you might be wondering where to source high-quality 5m composite decking boards. Here are a few key tips and platforms to consider:
Specialist Manufacturers
Some manufacturers specialize in longer-length boards. When buying directly from factories, especially in countries like China or Vietnam, you can often get better prices for bulk orders. Look for manufacturers that provide:
ISO or CE certifications
Product warranties of 10 years or more
Custom color and texture options
Online Retailers
Platforms like Alibaba, Amazon Business, or specialist building supply stores often carry composite decking 5m variants. Make sure to:
