B&B Sheet Metal’s Flat & Diamond Flat seam panels are manufactured by turning up the intersecting seams up, folding over, and flattening the joints by soldering. Flat & Diamond Flat seam roofing systems are typically used on roofs that are flat and minimum pitch 3”/12” or less. In constructing these panels, the pans are held in place with . Chapter #6 – Sheet Metal Duct Sealer and Leakage Duct Leakage. Duct leakage is a factor of the static pressure in the ductwork that allows for leakage to occur through holes, seams, joints and penetrations. Leakage is a loss of energy, which means a loss of money. This is why it’s so important to seal the ducts and to prevent leakage.
The Longitudinal Seam in Rectangular Duct is either a Pittsburgh Lock or a “Snap” Lock. Both types are formed on a machine that takes a sheet of metal and rollforms a profile on each of the flat edges — a Male Flange on one edge and a Female Pocket on the other edge. The Transverse Connection options are Slip & Drive, Ductmate, or TDC/F.A variety of seams are used to connect pieces of sheet metal in construction, auto body creation and fine art sculpture. The type of seam used depends largely on the application; some seams are created entirely by machine or in a metal shop, while others are made to snap together without requiring welding or soldering on site.sections of sheet metal. The following information will focus on the most commonly used types of seams, and key points for installers to remember in performing their work. 15.1. Overlaps . The simplest and most basic seam is the lap joint. This style joint is commonly used for flashings and end joints in long panels
