In 2007 we moved into a custom made 19,000 sq ft. office, showroom, assembly and fab shop.
All of our equipment is set up in our show room for our customers to come and get familiar with our equipment. We have a complete “processing line” set up and networked, including metal detector, checkweiger (with rejects) and QualityStation cart.
We have facilities for training on our equipment and we have hosted many of our customers quality control regional meetings.
Next time you’re in San Antonio (doesn’t everyone come here at one time or another?) , please stop in and say hello!

We support and give back
