SL150
SL150 is Union Corrugating's snap-lock standing seam roof panel, installed with clips to allow expansion and contraction, with a 1-1/2-inch rib height and a 3:12 minimum recommended roof pitch over solid decking. The company's own SL150 Guide Specification states the panel achieves a U.L. 90 wind-uplift classification tested to U.L. 580, with a nominal 16-inch panel width rollformed from 24-gauge Galvalume steel in that specification's base product description. The product page states Miami-Dade County approval and lists Signature 200 and Signature 300 coating options.
