If quality didn’t matter

we’d all drive lemons

The process of quality in Cates industrial control panels

Cates designs and manufactures industrial control panels in volume for Original Equipment Manufacturers (OEM) and in smaller quantities for custom control panel orders. In order to maintain high quality across orders ranging from 3 panels to 3,000 panels, Cates invests in every part of our manufacturing – our process, facility, software, machinery, safety, training and continuous improvement culture. As UL 508A panel builders with over 40 years of experience, our panels are competitively priced, delivered on time, and thoroughly tested. You’ll see the difference in our process and our panels!

Customer Testimonials

First, I want to say Thank you for all you do for us. I2R has been easy to do business with, which is something I do not say very often about any company. You and your team are personable and really work hard to meet our demanding request dates. You have made great strides in improving delivery times and aligning our goals with yours. Many of my customers have made positive comments about the workmanship and quality of work that has been put into our panels, if my customers are happy, so am I. I2R’s Value Engineering workshop inspired both of us in finding product enhancements we can incorporate in our current and next generation products. I am excited to be working with a company like I2R and growing together.
