I'm going to install racking on a metal roof with all metal bracing under the metal roof in my shed. It just took over 150 mph wind from hurricane Ida and held up perfectly. My racking will be 2- 20 foot long ea. 3 foot apart to hold each 6 panel section . Panels will be about 39" x 65" each ,not purchased yet! The anchors are rated at 340 pounds straigh pull per anchor. They will be screwed into the metal bracing under the metal roof, same way the roofs 3 ft X 13 ft sheeting are attached. My question is how far apart should they be placed on each 20 foot section of racking with each rated at 340 pounds pull. I haven't been able to find this information anywhere. Here is a picture of the anchors I will use and have ordered. The racking will be super struts used in outdoor equipment use. I'm thinking of 2 foot apart, one every 2 ft. For a total of 11 per 20 roof section of racking.
