What are Box Gutters?

Box Gutters are a type of gutter that features a more square / rectangular boxy look, hence the name box gutter.

At K&M Sheet Metal and Gutter Supply, we offer box gutters in several profiles, since these are bent on a brake. Normally offered in 10′ and 20′, we can actually bend such profiles in up to 21′ lengths. Modifications such as roof flanges are common on custom profiles.

These gutters are commonly seen in commercial and industrial applications, but are also used in homes for a more clean and modern look.

Box gutters are offered in colored Kynar material (0.032″ aluminum and 24 gauge galvanized steel), 24 gauge galvalume plus, 0.027″ regular standard aluminum colors and in copper, both 16 oz and 20 oz.

We also offer custom lengths, colors and materials for along with downspouts, elbows, hangers, end caps, outlets and any other gutter accessories needed.
