7.1 Partially Sheltered Exterior Exposure

Examples of partially sheltered exterior exposures are open, under-house storage; parking areas below a piling-, column-, or post-supported buildings; and areas under roof overhangs, decks, screened-in porches, and walkways.

In partially sheltered areas, corrosion can significantly weaken nominally galvanized light gauge metal connectors in 5 to 10 years or sooner. When not concealed by exterior finishes, these areas can often be inspected to evaluate the condition of the connectors and determine when maintenance or replacement is necessary.
