Your Single Source for Custom Perforated Finished Products

Your Single Source for Custom Perforated Finished Products

Perforate. Then level, stamp, form, cut, notch, degrease, weld, finish and repeat.

When your program requires standard perforated sheets, perforated recoil or custom-sized perforated blanks, Diamond can produce and deliver direct. But what if you require more processing and finishing for your perforated products? Depend on Diamond.

Diamond Manufacturing is your one-stop shop for installation- and assembly-ready finished perforated products. We specialize in precision-sheet metal fabrication and offer a full spectrum of value-added, post-perforating processes to provide your team with a more complete finished solution.

Diamond offers extensive metal fabrication and secondary services including leveling, hemming and forming, laser cutting and profiling, stamping and punching, degreasing, welding, and finishing.

Save time and money by letting Diamond perform in-line perforation and fabrication at one facility. Avoid costly outsourcing and confidently manage your project with the knowledge that it will be completed on time and accurately.

Whether you need a single prototype or fulfillment of a volume order, Diamond has the scale, capacity and expertise to meet your need for fabrication of custom parts and components.
