21oz Treated Canvas Tarps

Tarp Supply’s Heavy Duty 21oz Canvas Tarp is the strongest canvas tarp that we offer.It is thus heavier than the 16oz (colors available: green, mustard tan, brown, olivedrab) and 18oz canvas tarps (colors available: mustard tan and olivedrab). Treated canvas is designed for outdoor use as the treatment gives off an odor and may leave stains/residue, including when used in direct contact with other products.

Heavy Duty 21oz Canvas Tarp
  • Industrial Standard Cut Size (finished size is 5-7% or up to 6-9 inches less after edges are folded and hemmed)

  • Silicon treated to resist water and mildew
  • Rust-resistant heavy duty brass grommets every 24 in on all sides and corners
  • Double-stitched seams and hems for extra strength
