The Type
B Wide Rib is the industry standard for corrugated Industrial
Roofing. It can be produced in galvanized steel, painted steel,
aluminum and stainless steel. All lengths are produced to
custom requirements. Standard width is 36" coverage,
limited availability in 30" coverage. This product has
excellent load carrying capabilities. The wide rib allows
for a narrow top opening, which is desired when rigid insulation
is to be used on top of the deck. When computing coverage
requirements, allow for laps at supports.

1.
Load tables are calculated using section properties
based on the steel design thichness shown in the Steel
Deck Institute (SDI) design manual.
2. Loads shown in the shaded areas are governed by the
live load deflection not in excess of 1/240 of the span.
A dead load of 10 psf had been included.
