Design and More

No Designer? No problem!

From private residential to expansive commercial projects, Concentric Fabrication LLC takes on all scopes. Our in house design team will work with you one on one, to help develop and bring to life your concept through digital renderings, drawings, and constructed samples. We not only work with metal, but have the knowledge and capacity to work with a multitude of materials; glass, wood, carbon fiber, stone, and concrete to name a few. Initial concepts are provided free of charge. If you would like to further develop your project with Concentric a design retainer based on the scope of work will be required. We love problem solving and have often picked up where others have waved the white flag.
