USING A SET OF HEM ROLLS: This video gives instruction on the proper use of the Mittler Bros. Hem Step Roll Set. This easy, three-step process creates hem rolls approximately 1/4″ deep on steel or aluminum up to .040″ thick without marring pre-painted aluminum. Rolls are available in HEAT-TREATED STEEL or COMBO STEEL & NYLATRON. PUNCHING JUSTContinue reading “Metal Fabrication Videos I Made At Work”

Steel & Aluminum Characteristics
Aluminum characteristics: The 3003-H14 has superior strength characteristics over pure aluminum and is easily welded with either TIG (tungsten-inert-gas) or oxygen-acetylene gas welders, yet remains malleable for shaping and bending. By comparison, a 6061-T6 aluminum alloy would yield even more strength than the 3003-H14, but the 6061-T6 is also more brittle and if welded, may develop stress cracksContinue reading “Steel & Aluminum Characteristics”
