Douglas Fir number 2, 2x6 rafters are spaced at twenty-four inches on center typically unless noted otherwise, with separate designations for warehouse and office areas. Purlins are spaced at eight feet on center typically unless noted otherwise. Edge nailing, intermediate nailing, and continuous edge nailing fasten the sheathing panels. A detail reference calls out conditions where 4x rafters occur.
