The SL175 panel’s design allows for application over various substrates, providing adaptability for different construction needs. Its ability to function as both a structural roofing system and an aesthetic element makes it a practical choice for projects requiring durability and visual appeal. When ordered with the factory-applied sealant bead, the StrongSeam SL175 can be used for Watertight Warranty roofing installations.  The ease of installation, coupled with its robust performance ratings, positions the StrongSeam SL175 as a reliable and efficient roofing solution for diverse architectural designs.
