Looking for special custom-cut sheets or blocks?

Assuming that our standard sheets & block sizes don't work for you we can certainly assist you with any custom-cut sheet or block sizes you need! Visit our special-cut shapes section if you are not looking for sheets or blocks.

Custom-Cut Sheet & Block Considerations:

There are some important things to consider when ordering custom-cut sheets & blocks. Here they are:

Sheet & Block Size Constraints:

Your sheet or block sizes need to fit within these dimensional parameters:

  • The maximum sheet or block length is 5000mm
  • The maximum sheet or block width is 1200mm
  • The maximum block height is 600mm

Costs & Wastage:

  • Special custom- cut sizes cost more than standard sheet & blocks sizes because it takes longer to cut and there is always wastage.

Longer Lead Time:

  • Lead times for custom-cut sheets & blocks is often longer than standard sizes.

Cutting Tolerances:

  • We can cut to +/- 2mm tolerance.

Have You Considered Cutting These Yourself?

  • Cutting polystyrene is pretty easy. A sharp knife or hacksaw blade does the job.
  • This could save you time & money!
