Make sure you have been properly instructed in the safe use of such equipment before trying to move your shed with it. For secondary wall members supporting formed metal siding, the design wind load deflection shall not exceed l /90. No other material can match the engineering options provided by steel. In the engineering and construction industry, any truss spanning more than 60 feet is considered to be long span, thus requiring engineering consideration (per International Building Code (IBC) 2015 Section 2303.4, Trusses [for design of]).
