The company's own SL175 Guide Specification states the panel achieves a U.L. 90 wind-uplift classification tested to U.L. 580, with a nominal 18-inch panel width (12-inch, 14.25-inch and 16-inch optional) rollformed from 24-gauge Galvalume steel in that specification's base product description. The product page states a 1-3/4-inch rib height, a 3:12 minimum recommended roof pitch, and Miami-Dade County approval.
