EPDM manufacturer that offer wide-width rolls(Up to 6m)-Shuangshi

Wide-width EPDM membranes provide a major advantage. As one of the few manufacturers in China capable of producing true one-piece wide-width EPDM sheets, Shuangshi New Material is helping contractors improve efficiency, reduce labor costs, and achieve more reliable waterproofing performance.

For warehouses, logistics centers, retail buildings, and large flat roofs, the wide-width EPDM can savings more time and labor. Contractors consistently report 20–30% faster installation when switching to wider EPDM rolls.

Not All Wide-Width EPDM Is the Same: True 6m Sheets vs. Stitched Narrow Rolls

Some producers—especially in regions such as India—achieve “wide width” by stitching or bonding multiple narrow rolls together. While these seams may not be visible at first glance, they often create:

1,Hidden weak points inside the membrane;

2,Premature failure along the internal stitched lines;

3,Separation after long-term thermal expansion and contraction;

4,Reduced reliability for roofing and pond liner applications;

This is very different from one-piece wide-width EPDM, which is manufactured through continuous extrusion and calendering.

Shuangshi: One of China’s Few Manufacturers Capable of Producing True 6m Wide EPDM

Shuangshi New Material is among the very limited number of Chinese suppliers that can produce one-piece, single-process EPDM membranes up to 6 meters wide, suitable for:

Commercial roofing,Residential roofing and Pond liners.

Our production advantages:

1, Continuous one-step forming, not stitched or glued;

2, Large-width calendering equipment similar to top-tier U.S. manufacturers;

3, Stable mechanical properties across the entire width;

4, Consistent thickness, tensile strength, and elongation.

For contractors focusing on efficiency, long-term durability, and reduced labor costs, Shuangshi’s wide-width EPDM provides a clear advantage.
