The standard roof pitch for the Wilmington is a 5/12 pitch. A roof
pitch up to 6/12 can be provided if requested.
The typical design load allows for:
12 pounds per square foot dead load
30 pounds per square foot live load
20 pounds per square foot wind load. (Equates to 100 MPH)
There are variables that affect the design sizes of the members,
specifically the arches and arch connection hardware, and those
variables generally include live load conditions that are usually
location specific. Building Codes normally dictate the applicable
loads to be applied in the member size designs.
PRESSURE PRESERVATIVE TREATMENT
As noted in the component list above, the laminated wood arches are
fabricated with lumber pressure treated prior to gluing with
Penta-WR type “C”, at .3 pcf retention. The fascia boards also is
treated at .3 pcf retention. EnWood utilizes the pentachlorophenol
treatment because of its premier qualities and the treatment does
not discolor the wood and can be stained or painted.
