Introduction
®
CEMCO’s Sure-Span steel foor joist system is a patented, tested, and approved solution for commercial,
mid-rise, and residential foor framing assemblies. Sure-Span foor joists are manufactured with extra-
large openings (punch-outs) to allow for mechanical, electrical, and plumbing access without damaging
the structural integrity of the foor framing system commonly seen with typical c-shaped joists that require
cutting of the joist to accommodate these lines. Sure-Span provides long and sturdy foor spans, along
with fre-resistant and sound-reducing solutions for architects, engineers, and developers.
