Lengths & Tolerances
A quick quoting guide for preferred EPDM roll sizes and packaging.
Planning estimate: Wrapped foam compresses differently by material. Always confirm packaging fit before quoting.

Calculation details
Accepts thickness in mm or inches and roll length in feet or meters, then converts to the shared calculation units. Uses actual Fostek core dimensions: the 3in core has a 3.00in inside diameter and the 6in core has a 6.04in inside diameter. Both use a 0.125in S125 wall per side. Stretch, tension, and foam compression are not included.
Production Size Capability
What each family can currently be produced at, by thickness band and width. Reference only — nothing on this page changes a quote.

This is a calculated estimate, not a packaging standard.
The EPDM gaylord counts (26 HU/TL) are confirmed by Production and are fixed. Nothing here is.
This is arithmetic on nominal roll geometry and on trailer dimensions nobody at Fostek has measured.
Confirm with Production before it prices freight, and do not put it on a customer quote.
