Composite fencing, also known as WPC fencing (Wood Plastic Composite), is a modern creative alternative to traditional timber fencing. It’s made from a blend of recycled wood fibres sourced from post industrial pulp and high quality PE (polyethylene) plastics. This combination creates a strong, durable material that replicates the natural beauty of wood while offering superior weather resistance and minimal maintenance. Unlike timber, composite fence boards will not rot, warp, splinter, or require yearly painting or staining, making them a long term, eco friendly choice for modern gardens.
Concrete posts sets - yes, all our sets designed for concrete posts include everything you need to build and complete one full fence panel/bay. This includes all the slats you'll need for your chosen height, any trellis, a top and bottom rail, u-channel inserts for the concrete posts and insert caps for those inserts.
Yes, they sure can! Our composite fence panel slats have a honeycomb structure throughout which allows you to cut them down to any required width without compramising their structural integrity. They can be easily cut to the required size using your usual woodworking tools but we generally recommend using a mitre (chop) saw for ease and precision.
While the initial cost can be higher, homeowners save money long-term thanks to low maintenance – no staining, painting, or panel repairs required. In addition to this, our composite fencing carries a 15 year warranty protection.
Alpha Decking's 15 year warranty protects against warping, cracking, splitting, rotting and fungal decay caused by manufacturing defects, when subject to normal use and proper installation.
You can find more information and the terms of our full warranty here.
You have 3 options. Installation using our composite fence posts or aluminium fence posts installation using our u channel inserts for concrete post. These inserts which easily slot into your new or existing concrete posts allowing you to install our aspen composite fence panel slats or our willow composite fence panel slats. You can choose which option suits your fence installation best when purchasing your composite fence panel sets.
All of our composite fencing seamlessly and easily fits together using a tongue and groove system allowing you to make your fence up to your desire height.
