Are square gutters better than half-round gutters?
Yes, square gutters offer higher flow capacity and a modern appearance, making them ideal for properties requiring efficient rainwater management.
Square Gutter - Anthracite Grey

Do square gutters come with a warranty?
FloPlast square gutters are compatible with Hepworth, Brett Martin, and Hunter systems. For Galeco compatibility, please check product specifications or consult our technical team.
What size downpipe should I use with square gutters?
FloPlast 114mm square gutters connect to 65mm square or 68mm round downpipes (with an adaptor). Galeco 135mm gutters use a 70mm x 80mm rectangular downpipe.
How do I maintain square gutters?
Regular maintenance includes removing debris, flushing with water, and checking for leaks or blockages. Cleaning twice a year helps maintain performance. Use gutter protections for better gutter maintenance.
