Description
What is a Commercial Gutter Union Bracket used for?
A gutter union bracket (also known as a gutter joiner or connector) is the critical junction point in any 170mm commercial rainwater system. Unlike standard domestic clips, this commercial union is designed to bridge the gap between two 3-meter or 4-meter gutter lengths. It provides the mechanical strength to keep the run aligned while the internal gaskets create a pressurized seal against heavy rainfall.
Why Choose Heavy-Duty Unions for Industrial Buildings?
At ECO HEAT SHOP, we understand that commercial roofs collect massive volumes of water. Our 170mm union brackets are built to handle the “Deepflow” capacity required for warehouses and factories. The wide-radius design ensures that water velocity is maintained across the joint, preventing the turbulence and debris buildup that often occurs with inferior, narrow-seal connectors.
Engineered for Thermal Movement
Large commercial buildings undergo significant thermal expansion and contraction. This gutter union bracket features internal “expansion lines” and high-grade EPDM rubber that maintains its elasticity in temperatures ranging from -40°C to +90°C. This ensures that as your gutters grow and shrink throughout the seasons, the joints remain 100% watertight without the need for messy silicone or additional fixings.
