Agricultural Tarpaulin Guide: Farm Covers, UV Resistance and Reusability

For long-term or repeatedly used farm covers, PVC-coated polyester tarpaulin can be a practical choice when waterproofing, tear resistance, abrasion resistance, UV performance, and repeated handling are important.

It is commonly used for applications such as:

• hay and straw covers
• feed storage covers
• farm machinery protection
• general outdoor farm storage
• reusable weather covers

However, PVC is not the best material for every agricultural application. If you need a lighter, lower-cost cover for temporary or seasonal use, PE or HDPE tarpaulin may be more practical. If airflow, shade, or light transmission is the priority, mesh or other specialized agricultural fabrics may be more suitable.

For a reusable agricultural tarp, you should look beyond GSM alone. Consider how the cover will actually be used, including:

• UV and sunlight exposure
• rain and moisture
• wind and fastening stress
• abrasion from rough surfaces
• folding and handling frequency
• expected reuse
• storage conditions between uses

The best agricultural tarpaulin is not simply the heaviest material available. It is the cover that matches what you are protecting, how long it will stay outdoors, and how often you expect to reuse it.

What Type of Tarpaulin Is Best for Agricultural Use?

There is no single tarpaulin material that is best for every agricultural application. The right choice depends on what you are protecting, how long the cover will stay outdoors, and whether you need temporary use or repeated reuse.

For hay, machinery, feed, or general farm storage that will be covered repeatedly or left outdoors for longer periods, PVC-coated polyester is often considered because it combines waterproofing with good mechanical durability and fabrication options.

For lighter seasonal protection, PE or HDPE may be more practical because it reduces weight and cost. Where ventilation or shade is more important than full waterproofing, a mesh-type material may be the better fit.

There is no single “best agricultural tarp”; the right material depends on what you are protecting, how long it will stay outside, and how often the cover will be reused.

Is PVC Tarpaulin Suitable for Hay, Feed and Farm Covers?

Yes. PVC tarpaulin can be a practical choice for hay, feed, machinery and general farm covers when you need waterproof protection, mechanical durability and repeated outdoor use.

For hay and straw, the tarp should not be treated as the entire storage solution. University of Minnesota Extension guidance on outdoor hay storage also emphasizes moisture control, keeping bales off wet ground, and using suitable covering.

For machinery or general farm storage, you should also consider the shape of the equipment, contact with sharp or abrasive surfaces, wind exposure and how often the cover will be removed and reinstalled.

PVC tarpaulin is most suitable when the farm application requires a reusable waterproof cover that can withstand repeated handling and extended outdoor exposure.

Why Does UV Resistance Matter for Agricultural Tarps?

Farm tarps often spend long periods in direct sunlight, so UV resistance and outdoor durability affects how well the material retains flexibility, surface condition, and usable performance during repeated outdoor exposure.

UV performance is especially important when you use tarps for open-field hay storage, machinery parked outdoors, long seasonal coverage, strong-sunlight regions, or applications where the same cover will be reused over multiple cycles. In these conditions, prolonged sunlight can gradually contribute to fading, surface aging, stiffness, and loss of flexibility.

“UV resistant” should not be treated as a guaranteed service-life number. Actual durability also depends on climate, material formulation, installation, handling, abrasion, and how the tarp is stored between uses.

How Should Farm Application Change Tarp Selection?

Different farm applications expose a tarp to different risks, so you should select the cover based on what you are protecting and what you need to protect it from. Rain protection, sun protection, airflow, shade, and light transmission are not the same requirement.

Rain protection and sun protection are not the same requirement. A fully waterproof, opaque agricultural tarp may work well for stored hay, feed, or machinery, but living crops may still need light, airflow, and temperature control.

For this reason, you should not assume that one agricultural tarpaulin specification is suitable for every farm application.

If the cover may contact rain, damp storage, fertilizer, cleaners or oil, see our waterproof, mildew and chemical resistance guide for the questions and test data to include in your specification.

What Determines Whether a Farm Tarp Can Be Reused?

A farm tarp’s reusability depends on how well the material withstands repeated outdoor exposure, handling, and storage—not on GSM alone.

The main factors are:

• UV exposure — Long periods in direct sunlight can gradually affect flexibility, surface condition, and overall material performance.
• Wind — Repeated movement and flapping can place stress on the fabric, edges, and attachment areas.
• Abrasion — Contact with ground, machinery, timber, bales, or other rough surfaces can wear the cover over time.
• Folding and handling — Frequent removal, folding, dragging, and reinstallation can create additional mechanical stress.
• Fastening — Poor or uneven attachment can concentrate loads and increase local damage around edges or fixing points.
• Storage between uses — Keeping the tarp clean, dry, and properly stored helps reduce unnecessary damage when it is not in service.

Two tarps made from the same GSM can have very different reuse performance if their construction, outdoor exposure, fastening, handling, and storage conditions are different.

For buyers, this means “reusable” should not be treated as a fixed service-life claim. The more useful question is whether the tarp’s construction and expected use conditions are suitable for repeated farm applications over time.

What Should You Confirm Before Choosing an Agricultural Tarp?

Before choosing an agricultural tarp, start with the actual farm application rather than selecting by GSM or material name alone.

Confirm these eight points:

• What are you protecting? — Hay, feed, harvested crops, machinery, equipment, or another farm application
• Indoor or outdoor? — Outdoor use usually places more importance on UV, rain, wind, and weathering performance
• Expected exposure period — Temporary, seasonal, long-term, or repeated use
• Reuse frequency — How often the tarp will be removed, folded, transported, and installed again
• Rain / moisture exposure — Whether full waterproofing is required and whether trapped moisture or condensation could become a concern
• UV / climate — Sunlight intensity, temperature, and general weather conditions at the site
• Wind and fastening — Expected wind exposure and how the cover will be secured during use
• Roll material or finished cover — Whether you will fabricate the tarp yourself or need a ready-made cover

The key question is:

What does the cover need to protect against, and how will it actually be used?

Once those conditions are clear, you can choose an agricultural tarp that balances weather protection, handling, durability, and reusability without specifying more material than the application requires.

FAQ

 

What type of tarp is best for long-term agricultural use?

There is no single tarp material that is best for every agricultural application.

For repeated heavy-duty outdoor use, PVC-coated polyester tarpaulin is often a practical choice because it can provide waterproofing, tear and abrasion resistance, and good durability under repeated handling.

For lighter seasonal or temporary coverage, PE or HDPE tarpaulin may be more practical because it is lighter and usually more economical.

The right choice depends on what you are protecting, how long the cover will stay outdoors, and how often you expect to reuse it.

Is PVC tarpaulin suitable for hay covers?

Yes. PVC tarpaulin can be suitable for hay and straw covers where you need waterproof protection, tear resistance, UV performance, and repeated reuse.

However, the tarp is only one part of proper hay storage. You should also consider drainage, keeping bales away from wet ground, secure fastening, and preventing water from collecting on the cover.

Can PVC tarpaulin be used to cover farm machinery?

Yes. PVC tarpaulin is commonly considered for outdoor farm machinery because it can protect against rain, sunlight, dust, and abrasion.

You should still match the cover to the equipment shape, exposure conditions, handling frequency, and any sharp or abrasive contact points rather than selecting by GSM alone.

Why is UV resistance important for farm tarps?

Farm tarps are often exposed to direct sunlight for long periods.

UV resistance helps slow the effects of sunlight on the material, including fading, surface aging, stiffness, and loss of flexibility. It becomes especially important for open-field storage, machinery covers, long seasonal use, and tarps intended for repeated reuse.

Does UV-resistant mean the tarp will last a fixed number of years?

No.

UV-resistant does not mean a guaranteed service life. Actual durability depends on several factors, including sunlight intensity, climate, material formulation, wind, abrasion, fastening, handling, and how the tarp is stored between uses.

A supplier should therefore avoid treating “UV resistant” as a universal 3-year, 5-year, or other fixed lifespan claim unless that claim is supported by a defined product specification and use condition.

What makes an agricultural tarp reusable?

A reusable agricultural tarp needs to withstand both outdoor exposure and repeated handling.

Important factors include:

• UV and weathering performance
• tear resistance
• abrasion resistance
• flexibility
• secure attachment and reinforced areas
• resistance to damage during folding and movement
• proper cleaning and storage between uses

Reusability depends on the complete material construction and how the tarp is used—not simply on GSM or thickness.
