#1 · Best Overall

1. CARTMAN 16×27 Lumber Tarp

• Dimensions L x W: 27"L x 16"W
• Material Type: Vinyl
• Size: 16×27+4×8

Best for: Versatile flatbed tie-down.

Why it ranks #1: Its 16' x 27' size, 4-foot drops, 8' x 4' flap, 18-ounce vinyl, padded D-rings, and full-perimeter grommets suit broad flatbed cargo use.

Full-perimeter grommets pair with D-rings on the CARTMAN 16-by-27-foot tarp, giving haulers multiple ways to secure an 18-ounce vinyl cover. Its 4-foot drops and 8-by-4-foot tail flap extend coverage around large cargo, while the vinyl is specified to protect loads from rain, snow, wind, and sun exposure.

The 16-by-27-foot body and 4-foot drops provide coverage for large loads, while the 8-by-4-foot flap adds material at the tail. For securing, D-rings and full-perimeter grommets accommodate straps, hooks, or ropes, so crews can use their preferred tie-down method. The 18-ounce vinyl is described as waterproof, and reinforced edges and padded D-rings help resist wear during fastening. This combination suits cargo protection on flatbeds and trailers, with dimensions worth checking against the load.

Skip it if you need a 6-foot drop and a stated lightweight 14-ounce construction; US Cargo Control’s LLT20286-BLK lists both.

CARTMAN suits flatbed operators who want broad cargo coverage and a choice of grommets or D-rings for tying down. Its 4-foot drop is the main boundary for loads that need deeper side coverage.

• Dimensions L x W: 324"L x 192"W
• Material Type: Polyvinyl Chloride (PVC)
• Size: 18oz-16' x 27' (4' Drop)

Best for: Large-load rear coverage.

Why it ranks #2: The 16' x 27' cover uses 18-ounce PVC and includes a 4-foot drop with an 8' x 4' rear flap for cargo coverage.

An 8-by-4-foot rear flap gives this 16-by-27-foot SUMORISE tarp extra coverage at the tail, helping shield cargo ends from moisture and debris. Its 18-ounce PVC construction and reinforced D-rings make it a substantial option for flatbed operators covering large or oversized loads on the road.

The 16-by-27-foot body is specified for large cargo, while the 4-foot drop and 8-by-4-foot rear flap extend coverage around the load’s sides and back. That added tail coverage can help keep moisture and debris from reaching exposed cargo ends. The 18-ounce waterproof PVC material provides weather protection, and reinforced D-rings give tie-down points for securing the tarp. Before hauling, match the dimensions and flap arrangement to the load and trailer.

Skip it if you need a 14-ounce option with stated heat-sealed seams; US Cargo Control’s 24-by-18-foot LLT24188-BLK has those specifications.

Choose this SUMORISE tarp when a large flatbed load needs a 4-foot drop and added rear-flap coverage against moisture and debris. Its 16-by-27-foot footprint is the key fit consideration, especially for smaller cargo.

At 20 by 28 feet, this tarp offers a long coverage area for lumber hauling, and its 6-foot drop flap extends protection along the load edges. Three rows of 2-inch D-rings and grommets provide securing points, while heat-sealed seams join the 14-ounce PVC-coated polyester.

This Mytee Products listing supplies two 20-by-27-foot tarps, giving operators a pair of large covers for flatbed cargo. Each has 6-foot drops and a 6-by-8-foot flap or tail, while the 14-ounce vinyl is described as superlight yet tough.

• Material Type: Polyester, Polyvinyl Chloride (PVC)
• Size: 20' x 16' (6' drop)
• Weight: 42 lb

Best for: Machinery and steel loads.

Why it ranks #6: Its 20' x 16' size and 6-foot drop are paired with multiple D-ring rows, wear pads, grommets, and 14-ounce PVC-coated polyester.

A 20-by-16-foot body with 6-foot drops gives this US Cargo Control steel tarp a defined fit for flatbed cargo, machinery, or equipment covers. Its 14-ounce PVC-coated polyester is specified as easier to lift and position than standard 18-ounce tarps, while heat-sealed seams and multiple D-ring rows support securing the load.

The 6-foot drops extend coverage around cargo, and the 20-by-16-foot dimensions suit machinery or equipment when that footprint matches the load. Two D-ring rows on the ends and three on the sides provide tie-down points, with wear pads at the rings helping protect the tarp under tension.

• Dimensions L x W: 29.13"L x 20.08"W
• Material Type: PVC-coated polyester
• Size: 20 x 16 ft
• Weight: 44.5 lb

Best for: Reinforced steel-load tie-down.

Why it ranks #7: The 20 x 16-foot steel tarp uses 14-ounce PVC-coated polyester, with double-stitched reinforced edges and D-rings backed by wear pads.

Wear pads behind the D-rings address a key stress point on this 20-by-16-foot Wowangce steel tarp, helping prevent tearing under tie-down tension. Its 14-ounce PVC-coated polyester is specified as waterproof and tear-resistant, while double-stitched reinforced edges add support for securing flatbed cargo through varied weather.

The 20-by-16-foot size gives this tarp a defined footprint for steel or other flatbed cargo, and reinforced edges with double stitching support repeated handling. Each D-ring has a wear pad behind it, intended to prevent tearing under tension when securing heavier loads. The 14-ounce PVC-coated polyester is described as waterproof and tear-resistant, with protection from rain, snow, wind, and UV rays.

8. LUMONTIS 20×20 Tarp

• Material Type: 18oz PVC Lumber Tarps, Cargo Flatbed Tarp /…
• Size: 18oz-20' x 20' (6' Drop) Waterproof Tarp

Best for: Deep-drop square coverage.

Why it ranks #8: This 20' x 20' flatbed tarp is specified as 18-ounce PVC with a 6-foot drop and includes a listed one-year manufacturer warranty.

A 6-foot drop gives this LUMONTIS tarp deeper side coverage than a shallow-drop cover, while its 20-by-20-foot square footprint suits loads that call for broad, balanced coverage. The specified 18-ounce PVC construction and reinforced D-rings make it an option for flatbed operators seeking a heavy-duty tarp for truck or trailer cargo.

The 20-by-20-foot size provides a square coverage area, and the 6-foot drop extends down the load sides. That configuration may suit cargo needing more side coverage than a shorter drop offers, provided the footprint matches the load. The listing specifies 18-ounce PVC material and reinforced D-rings, pairing a heavy-duty tarp material with reinforced tie-down points. Since the provided details do not specify a flap or seam construction, buyers should base selection on the stated size, drop, and hardware.

Skip it if you need a specified tail flap and grommets; CARTMAN’s CM-1627-4X8 lists an 8-by-4-foot flap and full-perimeter grommets.

This LUMONTIS tarp suits operators whose cargo needs a 20-by-20-foot cover, 6-foot drops, and reinforced D-rings. The supplied details do not specify a flap, so buyers needing tail coverage should account for that boundary.

9. EFQKLPY 16×27 Tarp

• Dimensions L x W: 323.99"L x 192"W
• Size: 16'x27'

Best for: 14-ounce wide-load cover.

Why it ranks #9: Its 16' x 27' format and 14-ounce industrial PVC vinyl are relevant to flatbed cargo, though the supplied details offer fewer tie-down specifics.

A 16-by-27-foot footprint gives this EFQKLPY tarp broad coverage for regular and large cargo, without relying on extra tarps or patches according to its product details. The 14-ounce industrial PVC vinyl is described as waterproof for use in different weather, making this a lighter-material option for transportation teams covering flatbed loads.

The 16-by-27-foot size is intended to cover regular and large cargo, and the 4-foot drop adds coverage down the sides of the load. That can simplify covering a broad load with one tarp rather than adding patches or another cover, as the listing specifies. Its 14-ounce industrial PVC vinyl is described as waterproof in different weather and suited to daily use by professional transportation teams. Check that the dimensions and drop suit the cargo before loading.

Skip it if you want an 18-ounce tarp with stated reinforced D-rings; SUMORISE’s 16-by-27-foot 4-foot-drop tarp lists those features.

This EFQKLPY option fits haulers covering regular or large flatbed cargo who value a 14-ounce waterproof PVC tarp in a 16-by-27-foot size. The 4-foot drop and listed dimensions remain important load-fit considerations.

10. Mytee Products Smoke Tarp

• Dimensions L x W: 192"L x 144"W
• Material Type: Vinyl
• Size: 12' x 16'
• Weight: 30 lb

Best for: Smoke-sensitive cargo cover.

Why it ranks #10: This 12' x 16' water-resistant vinyl smoke tarp is intended to shield cargo from exhaust smoke and dirt, making it less suited to general load coverage.

A smoke-tarp purpose sets this 12-by-16-foot Mytee Products cover apart: it is intended to protect flatbed cargo from exhaust smoke and dirt. The 18-ounce vinyl also provides water resistance, and the listing describes protection against wind, rain, snow, and sun. Its smaller footprint suits cargo needing a targeted cover rather than a large lumber tarp.

The 12-by-16-foot dimensions make this tarp a more compact coverage choice than large lumber-tarp formats, while its smoke-tarp use targets cargo exposed to exhaust smoke and dirt. Its 18-ounce vinyl is described as water resistant and suited to challenging weather, including wind, rain, snow, and sun. That combination can serve targeted load protection during transport, but the footprint should be matched to the cargo. The listing specifies water resistance, not waterproof construction.

Skip it if you need a waterproof 20-by-16-foot tarp with 6-foot drops; US Cargo Control’s LST20166-BLK lists those specifications.

This Mytee Products tarp suits haulers protecting a smaller cargo area from exhaust smoke and dirt while seeking water resistance. Its 12-by-16-foot size and water-resistant, rather than waterproof, description define the fit.
