Description

Commercial equipment and outdoor storage don't come in stock rectangle sizes. A tarp that's close enough leaves an edge exposed to weather, or drapes far enough past the load to catch wind and work itself loose. This rectangle and square tarp is cut to the exact length and width you enter, so what arrives is what actually covers the job — no compromise size, no folding down a bigger tarp and hoping the excess stays put. Whether you need a heavy duty outdoor tarp custom size for an oversized load or a smaller custom rectangular industrial tarp for a single pallet stack, it's cut the same way: to your numbers, not a size chart.

This shape covers most equipment, pallets, stacked material, and open storage areas, where straight edges and square corners are what need protecting. A tarp sized to the load has less loose fabric for wind to lift, which is the most common way a good tarp destroys itself before the fabric ever wears out.

Why Choose Our Heavy Duty Rectangle Tarps?

Cut to your numbers, not a size chart
No rounding up to the next stock bracket and no loose fabric left over. The tarp you order is the tarp you get.

Waterproof seams, not just waterproof fabric
Heat-welded rather than stitched, so there's no row of needle holes running through the barrier. That's where a cheaper tarp actually leaks.

A fabric weight for how you'll use it
18 oz for permanent outdoor exposure and rough handling, 12 oz for a tarp that comes on and off regularly. Neither is a compromise — they're built for different jobs.

How to Measure Your Heavy Duty Tarp

Step 1 - Length and width
Measure the length and width of what you're covering at the longest and widest points.

Step 2 - Add overhang
Add 6 to 12 inches of overhang per side for general use, or 12 to 24 inches for exposed or high-wind sites. For tall loads, add twice the height to your base dimensions so the tarp reaches down the sides.

Step 3 - Choose your fabric and hardware
Pick 18 oz or 12 oz based on how the tarp will be handled, then choose grommet spacing and whether to add reinforced webbing. Enter your final numbers for an instant price — every panel is cut to order.

Fabric Information

This rectangle and square tarp is built in either of our two solid coated fabrics — pick the weight that matches how the tarp will actually be used.

Tarp Armor — 18 oz, year-round

18 oz (610 gsm, 22 mil), 1000-denier PVC-coated fabric — our heaviest build. It resists tearing, abrasion, and oil and grease, and stays flexible down to -20°F instead of cracking at the folds. 7-year warranty. Choose it for equipment and storage that stays outdoors permanently or gets handled roughly.

Tarp Shield — 12 oz, easy handling

12 oz (410 gsm, 15 mil) PVC-coated fabric. Same 100% waterproof barrier, in a build light enough for one person to fold and re-deploy alone. 5-year warranty. Choose it when the tarp comes on and off regularly.

Both fabrics share the same construction: heat-welded seams with no stitch holes, a reinforced hem, and rustproof brass grommets set at the four corners or spaced at approximately 24, 18, or 12 inches around the perimeter. Welded D-rings are available at 24 or 12 inches, and 1.5" reinforced webbing can be added around the edge for wind or repeated tensioning.

Square panels are ordered the same way as rectangles — this is as much a heavy duty square tarp custom build as it is a rectangular one.

Frequently Asked Questions

For most commercial equipment and storage, 18 oz Tarp Armor is the safer default — it resists tearing, stays flexible down to -20°F, and carries a 7-year warranty. If the tarp gets folded and moved often, 12 oz Tarp Shield gives up some durability for a fabric one person can handle alone.
Four corners is enough for a tarp that sits flat and stays put. If the site is windy or the tarp gets tensioned often, spacing grommets at approximately 24, 18, or 12 inches spreads the load across more tie-down points instead of leaving the corners alone to hold it.
Add it if the tarp will be pulled tight, moved often, or exposed to sustained wind. The 1.5\" webbing sewn around the perimeter carries the tension instead of the fabric, so grommets stop being the weak point. For a tarp that's draped loosely and rarely handled, standard construction without webbing is sufficient.
Yes, within the rectangle and square family — order the length and width to the load's outer dimensions plus overhang. For genuinely irregular geometry with notches or angled edges, our Custom Tarps hub takes sketch uploads for CAD drafting. The same process applies whether you need a rectangle or a heavy duty square tarp custom cut.
Weight and construction. A hardware-store rectangle tarp is typically 3 to 6 oz polyethylene that splits and fades within a season. This tarp is 18 oz or 12 oz PVC-coated fabric with heat-welded seams and a reinforced hem, built for years of outdoor exposure.
6 to 12 inches per side covers most general storage and equipment use. Go to 12 to 24 inches per side for exposed, high-wind sites, or for tall loads where the tarp needs to reach down the sides — in that case add twice the height to your base length and width.
