KWM breaks ground on new facility

Manufacturing Marvels® features KWM Gutterman

Panther Line to be Discontinued

As of Friday, December 29, 2017, KWM will no longer make Panther 5" & 6" machines. If you own or plan to purchase a Panther machine before the year's end, know that it is still fully covered by KWM's Rock Solid Guarantee. And we will still keep inventory of Panther parts to service machines.

Panther was the first roll forming machine KWM built, so it was a challenging decision to discontinue it. But customers have noticed that our IronMan line—currently 9 machines with 34 gutter profiles—is more advanced, lighter in weight, and less expensive. So to respond to demand, we need to adjust our production to best fulfill customer needs.

Thank you for trusting KWM—we look forward to working with you for many more years to come!

Hanger Mark Now Available


Save substantial time on the ground!

Hanger Mark is an add on accessory for any IronMan K-style machine. It makes an indentation on the inside back of the gutter every 8" to indicate where to place your hangers. Patent Pending. 

Hanger Mark is now available for purchase for any new or used IronMan K-style profile machine.

KWM Expands Operations!


KWM Gutterman is excited to unveil our 15,000 square foot assembly plant!  We will be moved in and fully operational by the end of summer 2016. More room will allow us to keep up with your production demands. We would like to thank our loyal customers for their continued support to make this possible.
