Large Volume Guttering

Attractive commercial guttering capable of carrying large volumes of water

When it comes to industrial and commercial projects you're dealing with large roof areas. In our summer storms a big roof area means more water than a conventional eaves gutter can carry.

OG Big One gives you the flexibility to design your gutter to your rainwater capacity requirements with girths of up to 600mm. The slotted Old Gothic face adds character and style to your building line.

OG Big One is easily fixed to any conventional building material, and the concealed fixing brackets provide a smooth appearance. It is available in a variety of finishes including zinc/al, prepainted colour steel or galvanised. It comes with a full range of accessories including stop ends, mitres and concealed brackets.
