Providing Quality Worldwide
We’ve sold over a billion
square feet of Spancrete
hollowcore precast worldwide.
That’s because Spancrete
precast structural systems
are practical, economical
and versatile.They erect
faster than other systems,
are cost competitive and
offer lower maintenance,
higher occupant satisfaction
and better resale value.

Spancrete’s wealth of information and data allowsdesigners and builders to proceed with confidence.
Since 1960, the Spancrete Manufacturers’Association has been conducting extensiveresearch and testing on prestressed hollowcoreplank. Our products and techniques arecontinuously updated in accordance withchanging technologies, codes and applications.Information and statistical data derived fromthese studies have been published and areavailable to our customers in several forms.“Span Notes” directly address features andbenefits as well as aspects of design using
Spancrete plank.“Spancrete Research Notes” provide detailed engineeringdata on subjects such as load distribution, shear design, diaphragm actionand other characteristics.We regularly publish brochures illustratingsuccessful applications of precast plank in a wide variety of structures.
Spancrete floor systems have been shown by test at Riverbank AcousticalLaboratories to be resistant to high levels of sound transmission andimpact noise transmission.The above representative values give a generalidea of the high level of acoustical performance which Spancrete can achieve.Specific detailed values are available from your local Spancrete producer.
Fire RatingsSpancrete fire ratings can be obtained to meet the requirements ofyour state and local building codes. Consult your local manufacturerfor information, as code requirements vary from region to region.
