any point along the length of exposed primary structural members supporting roofs over
manufacturing, storage and warehousing, or maintenance shops must be capable of
safely supporting a suspended concentrated load of 8.90 kN (2000 pounds) in addition
to dead loads. For all other occupancies, a concentrated load of 0.89 kN (200 pounds)
must be used instead of 8.90 kN (2,000 pounds).
2-3.4.7 All structural steel exposed to the weather must adequately protected to
prevent corrosion. All galvanized structural steel shall in accordance with ASTM
