Overview
A large-format 20x20 foot poly tarp at 10 mil thickness, aimed at covering big loads such as construction materials, vehicles, or full roof sections.
Formerly sold under the AmazonCommercial brand, this tarp carries the specs of a mid-to-heavy-duty cover: double-sided laminated polyethylene, heat-sealed seams, and rope run through the hem for extra hold at the grommets. Brown on one face and silver on the other lets it double as a reflective cover or a lower-visibility one.
- 20 x 20 foot finished size
- 10 mil thick, double-sided lamination
- Grommets every 36 inches with rope in hem
- Brown/silver reversible
Who it's for
Suited to contractors and property owners covering large stacks of material, equipment, or roofing sections. Overkill for a small item that only needs a corner of coverage.
Pros and cons
- Large 20x20 foot coverage for big jobs
- 10 mil thickness with double-sided lamination
- Reversible brown/silver faces
- Rope-reinforced hem at the grommets
- Bulky to handle and fold given its size
- No review data included with this listing
Performance notes
The double-sided lamination and heat-sealed seams are the load-bearing claims here, meant to keep water out under sustained exposure. Metal grommets every 36 inches with rope reinforced through the hem carry the tie-down load on a tarp this large, and the maker states it resists mildew and can be washed and reused.
