Structural

The loading characteristics of the buildings are:
Snow Load: 30 PSF
Wind Load: 30 PSF (110 MPH Maximum)
Floor Load: 50 PSF


Framework

Structural members for corners are 3” x 3”, ¼” aluminum angle. Structural members between panels are 4” x 2½”, 3/16” aluminum “T” extrusion. Top frame will be 2 ½” x 2 ½”, 3/16” aluminum angle. All aluminum structural members will be 6063 alloy, T6 temper, finished with grey powder coat paint.


Panels

Wall panels are a minimum ¾” thick sandwich construction. Exterior of panel is smooth white painted aluminum laminated to high density OSB board. Panel interior will be 1/8” gray vinyl covered hardboard. Panels will be caulked with a urethane sealant and fastened to structural members with plated screws.


Ceiling

Ceiling panels are a minimum ¾” thick sandwich construction. Interior of panel is 1/8” white vinyl covered hardboard laminated to high density OSB board. Top of panel will have an aluminum vapor barrier.


Floor/Base
