Specifying the correct material and creating and designs and blueprints that make the process easy is what I do. For example, proper weld callouts can affect how the final product looks. Whether it's 304 stainless steel, A36 mild steel, or A2 tool steel, or any other grade, proper material selection and (finishing treatments) is key to the best designs. Good 'ol 6061 aluminum is one my favorites too!I work closely with the fabricators that my clients' use so that I understand their capabilities. By doing this, costs are controlled and delivery times are quicker.
