Machinery used to Fabricate Ductwork Coilline - Plasma Table- used for cutting precise fittings at a high speed. Shear- used for cutting rough shapes out of medium sized pieces of sheet metal. Spiral Machine- produces straight round spiral ducts Brakes (hand, air, hydrolic ) Snap Lock-designed for commercial and industrial. Inboard rolls form a female button lock and the outboard rolls form a button punched right angle flange. Pittsburgh- a set of rollers forms a seam on one side and a 1/4 “ bend on the opposite that sits inside the seam. Beader - used to reinforce duct and is 4-5 times faster then cross breaking.
