40 oz Vinyl Coated Polyester Tarps

About

Sigman 40 oz vinyl coated polyester tarps are the maximum-duty option in our vinyl tarp group, built for extreme outdoor and industrial environments where lighter materials wear out too quickly. This class is selected when material mass, abrasion tolerance, and long service life are more important than easy handling. Common applications include industrial roof covers, power equipment protection, and long-duration outdoor shielding in high-sun regions such as Arizona, California, Florida, and Texas. Specifications Material: 40 oz PVC vinyl-coated polyester Fabric weight: 40 oz per sq. yd. Thickness: Approx. 42 mil Waterproof: Yes UV performance: Extremely high UV resistance for long-term exposure Tear and abrasion performance: Maximum-duty class in this vinyl tarp group Chemical resistance: Oil, acid, grease, and mildew resistant Grommets: Solid brass, approximately every 2 ft on all sides Origin: Made in USA Best For Extreme-duty industrial roof and canopy coverage Power equipment, generator, and heavy machinery protection High-abrasion sites with long-duration outdoor exposure Projects where maximum material durability is the top priority High-UV climates requiring long service life under harsh sun Not Ideal For Frequent quick deployment/removal where lighter handling is needed Routine everyday covers where 10 oz, 14 oz, or 18 oz is sufficient Applications where 22 oz already meets durability requirements Jobs where lower material weight is more important than max durability 40 oz vs 10 oz, 14 oz, 18 oz, and 22 oz Vinyl Coated Polyester 10 oz : Lighter and easier to handle; best for routine coverage, not maximum-duty environments. 14 oz : Mid-heavy durability balance; 40 oz is for much harsher wear and longer extreme use cycles. 18 oz : Heavy-duty standard; 40 oz is the jump when duty demands exceed typical heavy-duty service. 22 oz : Extra-heavy-duty and strong for hard use; 40 oz is the top tier for maximum material mass and durability. 40 oz : Best for extreme-d
