Copper Rainwater Systems

     Quick Contact

Please don't hesitate to contact us to find out more by submitting the contact form below...

JML HM offer a vast range of complete rainwater systems in Natural Copper finish and offer gutter sizes 200, 250, 333, 400 and 500mm. These measurements relate to the total width of the material used and not the gutter size.


200 and 250mm are specifically designed for the Domestic Market. This covers anything from a small extension to a medium / large sized house. The gutter joints, corners and running outlets should be soldered together using the appropriate tools and equipment which JML HM hold in stock. Gutter bracket spacing 400mm to ensure the system copes with potential snow loading / Downpipe brackets 1 per metre.


The 333 system is aimed at large housing with large high pitched roofing and also small commercial buildings. Being a large gutter and downpipe combination the system is better equipped to handle high quantities of rainwater run off at a much higher speed than the smaller systems ensuring effective clearance of the roof. 333 Half Round or 333 Box Gutter are 153mm diameter and  120mm wide respectively in section with downpipes at 100mm. All brackets and clips are far stronger to cope with the weight and snow loads. Gutter bracket spacing 400mm / Downpipe brackets 1 per metre.


Further to the 200, 250 and 333, JML HM also offer the 400 AND 500 gutter for large commercial buildings. 120mm downpipes are also available for these systems.


When selecting any gutter system, the height and pitch of a roof affects the total area and speed and quantity of rainwater run off. Rainwater calculations can be carried out to ensure that the gutter specified will cope with run off in the worst possible conditions. If you are unsure which size gutter best suits your building requirements, please contact us with full dimensions of the roof area along with roof pitch/slope and project location.


Downpipes and bends for all systems have male and female sockets allowing quick install without the requirement for glue or solder.


JML HM hold extensive stocks to ensure project deadlines are met. For items not in stock a 2/6 week lead time should be expected depending on the product required.
