PANEL STORAGE AND HANDLING

Like all building materials, APA trademarked structural wood panels  should be properly stored handled and installed to assure superior in-service performance.

Protect the edges and ends of panels especially tongue-and -groove and shiplap-edged panels. Place panels to be moved by forklift on pallets or bunks when received to avoid damage by fork tines.

Panels to be transported  on open truck bed should be cover with standard tarpaulins. For open railcar shipment, use "lumber wrap" to avoid extended weather exposure.

Store panels whenever possible under a roof, especially if they won't be used soon after received. Keep sanded and other appearance grades away form open doorways, and weight down the top panel  in a stack to help avoid any possible warpage from humidity. If moisture absorption is expected, cut steel banding on panel   bundles to prevent edge damage.

Panels to be stored outside should be stacked on a level platform supported by 4x4  stringers or other blocking. Never leave panels or the platform in direct contact with the ground. Use at least three full-width supports along the eight-foot length of the panel-one centered and the others 12 to 16 inches from each end.

Cover the stack loosely with plastic sheets or tarps. Anchor the covering at the top of the stack, but keep it open and away from the sides and bottom to assure good ventilation. Tight coverings prevent air circulation and, when exposed to sunlight, create a "green-house" effect which may encourage mold formation.
