Online Diamond Plates’ roots can be traced back to 2013 and a small suburban garage in Golden, Colorado.

What began as a side business to help fund my soon to be born son’s education, quickly outgrew the garage.   Although Online Diamond Plate has grown considerably since its humble beginnings, we hold strong to the values that got us here and remain a small family owned business located in Golden, Colorado.

Online Diamond Plate now has among the largest selection of diamond plate sheets and accessories available for purchase online to help you get the job done!  Whether you need a single custom diamond plate part made for your Garage, or a truckload of diamond plate sheets to cover the walls in your warehouse…   We’ve supplied diamond plate projects large and small!

At Online Diamond Plate we stock  aluminum diamond tread plate sheets in thicknesses ranging from .025″ embossed to .125″.   In addition to the standard aluminum polished chrome (silver) finish, we also inventory black,  gray diamond plate, and red diamond plate sheets to give your project the look you desire!  Need diamond plate sheets CUT-TO-SIZE for your project?  We can get this done too, simply select the diamond plate sheet and color and check the “Custom Cut” box and we’ll provide the exact cuts you need.
