Commercial Aluminum Box Gutter

Style A - Available in several colors. 0.032" Kynar Aluminum.

Box Gutters are commonly used in large industrial & commercial applications, but the smaller 5" and 6" profile can also commonly be found in more modern homes. The advantage of box gutters, is due to their shape, which allows for a much larger water carrying capacity.
Box Gutters are bent in a brake, and therefore are offered in 10' lengths only. For this reason, these gutters can also be customized, with added roof flanges, for example.
Our profiles are made to fit the K-Style and Box gutter hangers we sell and will work with most K hangers. Please refer to the submittal to ensure this will work with your favorite hanger.
K&M also supplies gutter guards / screens for all gutter profiles we offer along with all accessories needed for your gutter system.
Custom lengths, sizes and heavier gauges may be available. Please contact us for pricing.

Joining gutter lengths / seams

To put 2 lengths of gutter together, simply cut back the front bead / lip of the gutter 1" or more depending on your needs. Do the same for the hem in the back if present. Cut where needed to create tabs. Overlap the 2 lengths of the gutter and join them by soldering if possible, or with zip screws / rivets and sealer if not.
Coupling pieces can be manufactured if needed. Keep in mind that using a coupling piece like a cover plate gives the appearance of 2 seams. Splice plates can also be manufactured. Unlike cover plates, these sit on the inside of the gutter, giving the appearance of one seam, like overlapping 2 gutter lengths.
