If you expect heavy loads on your cover on a regular basis, consider our Super Strength option.  

Super Strength


Super Strength adds one additional layer of twinwall polycarbonate to the inside of each core module.

  • Adds five pounds of weight to each side of the cover.

  • Increases the insulating value by 10%.

  • Does not change the outer dimensions or appearance.

Super Strength allows regular application of heavy loads, up to 1000 lbs distributed load on a DuraCore cover.
