We were asked by a customer to manufacture several thousand tube burners for installation in barbeque.
Our experience told us that by using a lock-seam tube instead of a welded tube we would produce the part more quickly, with reduced energy costs, and save our customer money. The lock-seam tube is a cooking-type elongated bar burner with numerous gas flow apertures, a top surface defined by a stiffening ridge, and a pair of laterally extending flanges.
We began by working closely with the customer during the design phase so we would be sure to meet their specifications. We actually designed the proprietary processes and engineered the tooling and custom machines needed to complete this project.
The burner is comprised of aluminized cold rolled steel and 304 stainless steel. We pre-notched the sheet, which enabled us to cut several secondary operations out of the overall fabrication process, resulting in a much lower cost per part.
The sheet metal was then roll-formed, pierced, and bent into the required configuration prior to assembly. Following custom part masking, we used our proprietary selective powder coating to finish the tube burner. 20” long and 0.036” thick, these tube burners were fabricated to tolerances of ±0.005”. We now manufacture 100,000 of them a year for our barbecue industry customer. To learn more, please see the table below or contact us directly.
