Discover why FloPlast is the UK’s most trusted brand for rainwater systems. Our Black Square Line guttering offers trade-quality performance with a sleek, modern finish for any home.
In the world of rainwater systems, one name stands above the rest for reliability, innovation, and style: FloPlast. At The Wall Panel Centre, we don't just sell any guttering; we supply the FloPlast Black Square Line system, the market-leading solution trusted by trade professionals and discerning homeowners across the UK.
Whether you're a contractor needing a "fit and forget" system or a homeowner wanting the best for your property, here is why FloPlast is the gold standard.
FloPlast has earned its reputation as a market leader through decades of engineering excellence. For the professional installer, this means parts that fit perfectly every time. The FloPlast "Snap-Fit" technology isn’t just a marketing term—it’s a precision-engineered system that ensures easy assembly and a permanent, leak-free seal that prevents those frustrating (and costly) call-backs.
The FloPlast 114mm Square Line system is designed for those who want a contemporary edge. Unlike standard round systems, the sharp, clean lines of FloPlast square guttering provide a modern, architectural finish. The high-gloss black finish is a FloPlast signature, providing a premium look that stays deep and dark for years.
It’s not just about looks. FloPlast engineers their Square Line system to handle the British climate.
Higher Capacity: The square profile holds and moves more water than traditional half-round systems.
BS EN Standards: All FloPlast products are manufactured to stringent British and European standards (BS EN 12200-1 and BS EN 607), giving you peace of mind that the system can withstand heavy snow loads and torrential rain.
When you choose FloPlast, you are investing in a product built for the long haul.
UV-Stabilisation: FloPlast uses high-impact, UV-stabilised uPVC, meaning your black guttering won't turn grey or brittle under the sun.
Enhanced Seals: FloPlast's unique rubber gaskets are designed to allow for thermal expansion and contraction without losing their watertight integrity.
One of the reasons FloPlast is the market leader is the sheer range of components available. We stock the complete FloPlast suite, including:
FloPlast Square Downpipes (available in various lengths for zero-waste installs).
FloPlast Adaptors (to seamlessly join new square systems to existing round pipework).
FloPlast Fittings: From unions and running outlets to 135° and 90° angles.
