OUR STORY
In 2013, Online Diamond Plate was born out of a home garage in Golden, Colorado. What started as a small project quickly grew into a trusted supplier of aluminum diamond plate sheets, custom cuts, and trim moldings and other proprietary diamond plate products.
Even as we’ve grown to serve customers nationwide, we’ve stayed true to our small business values. Every order, big or small, is handled with care, integrity, and the kind of personalized service you can only get from a family-owned business.
