	** NOTE TO SPECIFIER ** SBC Industries; prefabricated flashings. . This section is based on the products of SBC Industries, which is located at: P.O. Box 610397 North Miami, FL 33261 Tel: (800) 228-2580 Tel: (305) 685-6350 Fax: (305) 685-6360 Email: susan@sbcflashings.com www.sbcflashings.com [ Additional Product Info and Data ]
	SBC Industries provides balance to quality roof systems with premium penetration flashings that address an array of problems in two series of solutions: 'D' Series flashings, which are split units designed to surround roof penetrations that are already connected such as equipment stands, pipe supports or activated electrical conduits; and 'S' Series flashings, built to slip over the top of unconnected items penetrating the roof common mostly in new construction. In addition to our wide array of standard construction penetration flashings, SBC prides itself on its ability to work with you - the designer - to design custom flashing solutions to solve any peculiar or unusual flashing condition. Whether custom or off-the-shelf, all SBC Industries' patented roof penetration flashings feature stainless steel construction, economical and efficient design, compensation for vibration and thermal expansion, and maintenance free use.
