Where required, floor deck sheets can be provided with crushed ends. This is the process of closing the end of the sheet ribs by ‘crushing’ the rib to form a slope to the end of the trapezoidal rib (refer to Fig.13.2a).

Crushed ends option is only available with the TR80+ profile.

Benefits – Where might it be used?

Crushed ends offer a number of benefits specific to certain types of construction or detail:

  • Quicker to install in single span situations as avoids need for end caps
  • Provides a greater concrete section locally to the shear stud, improving stud performance
  • Enables solid concrete strip over centre of support avoiding need for acoustic and/or fire profile fillers
  • Reduces grout loss on pre-studded projects where deck sheets have to be single span (refer to Fig.13.2b)
  • Popular in light gauge frame construction

As with all product options, crushed ends are not suitable in all situations as there are implications on sheet bundling and layout configurations. Contact SMD Technical or Operations teams for further guidance.

General Notes

  • Manufacturing tolerance on sheet lengths to be +/- 5mm.
  • Minimum sheet length which can be supplied with crushed ends is 1300mm. Sheets required between 650mm - 1300mm will be doubled up crushed both ends and cut in two. End caps should be specified for the uncrushed ends. Where this occurs, end caps will be supplied FOC.
  • Only sheets of the same length or up to 100mm difference will safely stack together in a given pack - cutting lists must take this into account when determining packs.
  • Crushed ends can be provided on all available gauges and grades of SMD TR80+ profile.
  • Optimum bearing support is 52.5mm.
