Open Web Steel Joists, K-Series, were primarily developed
to provide structural support for floors and roofs
of buildings. They possess the following advantages
and features which have resulted in their wide use and
acceptance throughout the United States and other
countries.
K-Series Joists are light in weight - they possess an
exceptionally high strength-to-weight ratio in comparison
with other building materials. Coupled with their
low price per pound, they contribute significantly to
lower building costs. An additional economy stemming
from their light weight is the fact that the structural
materials supporting the joists, such as beams and
Joist Girders, columns, and the foundations themselves,
can therefore be lighter, thus leading to even
greater economies.
K-Series Joists are standardized regarding depths,
spans, and load- carrying capacities. There are 64 separate
designations in the Load Tables, representing
joist depths from 8 inches (203 mm) through 30 inches
(762 mm) in 2" (51 mm) increments and spans through
60 feet (18,288 mm). Standard K-series Joists have a
2 1 /2 inch (64 mm) end bearing depth so that, regardless
of the overall joist depths, the tops of the joists lie in the
same plane.
