Retaining walls are among the most common structures in landscaping and construction, providing a host of practical and aesthetic benefits. These benefits can include creating a well-defined layout in your landscape and preventing soil erosion during periods of heavy rainfall. When it comes to building retaining walls, parallel flange channels (PFCs) provide much-needed structural support and can make or break your retaining wall. In this post, we take a closer look at why PFCs are a key component in strong and durable retaining walls.
What are Parallel Flange Channels?
PFCs are steel sections with two parallel flanges that are connected by a central web. Unlike tapered flange channels, PFCs have uniform flange thickness, giving them consistent strength and stability throughout and making them popular in construction. They can come in a variety of different sizes and dimensions to suit different structural applications and can be made from standard, Corten, or galvanised steel for added durability and resistance to the elements.
The Role of PFCs in Retaining Walls
When used in the construction of retaining walls, PFCs provide much-needed structural support and reinforcement, allowing the retaining wall to have a higher capacity to withstand soil pressure. Their unique design allows for even load distribution, reducing the risk of your retaining wall bending or warping even when exposed to high lateral pressure from ground shifts or buildups of water in the soil behind the wall.
At the same time, PFCs are also compatible with other structural elements, such as concrete sleepers or steel posts, allowing for a more robust and long-lasting retaining wall. The durability of PFCs, especially when they are galvanised or coated, protects them from corrosion and makes them one of the most popular options for both residential and commercial retaining wall construction.
Cost-Effectiveness and Ease of Installation
Another factor that contributes significantly to the popularity of PFCs is their cost-effectiveness and ease of installation. Because PFCs can often be pre-cut and fabricated to specific lengths, this reduces the need for on-site modifications or further customisations, saving time and labour costs. These standardised dimensions also mean that they are very compatible with other steel sections and other structural elements, making them easy to install even with no prior building experience. They are also highly versatile and can be seamlessly integrated into countless retaining wall designs, further reducing the complexity of construction.
