Hay Bale Tarps
|
| Your storage program | Material to review | Specification priorities | Buyer trade-off |
|---|---|---|---|
| Seasonal cover, large stack, limited handling crew | Woven PE tarpaulin with a suitable laminated barrier | Finished weight, UV requirement, seam quality and reinforced hems | Lower handling weight can be useful; a thin general-purpose sheet may underperform a purpose-made hay cover. |
| Frequent removal, refitting or repair | PVC coated polyester / vinyl tarp construction | Tear and abrasion behavior, weld integrity, fold handling and attachment reinforcement | Compare carrying weight and material cost against reuse and fabrication needs. |
| Exposed site or long cover spans | PE or PVC, selected as a complete cover system | Distributed fastening, corner reinforcement, stack geometry and site anchoring | A heavier sheet alone does not establish a safe wind rating. |
| Moisture escape is the main concern | Review the storage layout; consider a dedicated breathable hay-cover product only with supporting data | Air movement, drainage and verified vapor behavior | Open mesh is not a rain barrier. Standard PE and PVC weather covers should not be assumed breathable. |
Review the material construction in our PVC coated tarp guide. Compare barrier and seam requirements for waterproof tarp applications.
Measure over the actual stack from one intended finished edge to the other, then measure the row length and desired end coverage. A ground footprint or bale count alone misses the curved profile, stack height and side drop.
Measurement concepts only. The diagrams do not specify a safe stack, roof support, ventilation gap or anchor design.
Choose the lower cover edges and end drops. Keep the drainage route and access needs in view.
Record the over-top span, row length and stack changes. Add a simple end-view sketch and photos.
Agree whether the quoted dimensions are finished dimensions or cut dimensions before hems, pockets and seams.
19.69 × 44.29 ft · 81.00 m²
Body fabric only: 24.30 kg
Width = measured over-top span.
Length = stack length + 2 × end drop.
Weight = area × GSM ÷ 1,000.
Excludes hems, seams, overlap, pockets and hardware. Confirm the final drawing and finished weight with DERFLEX.
Need a shaped end, an access flap or a different fastening layout? Review custom tarp manufacturing options.
A large bale stack cover transfers wind and handling forces into a small number of attachment points. Specify the complete load path: sheet, seam, hem, reinforcement, hardware, tie and anchor.
Review reinforced hems, webbing loops, grommets or pockets against the actual tie direction. A hole through the main sheet creates a concentrated stress point.
PVC coated fabric and PE laminates need different joining settings. Approve the seam construction for the selected material and review joins where water may collect.
Stacks settle and covers relax. The attachment system should allow inspection and adjustment without pulling the cover into sharp bale corners or hardware.
Cover shape, drainage and site conditions also matter in outdoor storage tarp planning.
DERFLEX hay cover programs can be reviewed around PE or PVC construction, custom size, reinforcement and OEM needs. The items below are quotation variables, rather than a single fixed stock grade.
| Item | Options / information to confirm | Approval point |
|---|---|---|
| Material construction | PE laminated woven fabric or PVC coated polyester, according to the project | Approve the actual grade and material sample. |
| GSM & thickness | Specify finished fabric mass in g/m² and thickness separately. | Confirm target values and tolerances; do not infer thickness directly from GSM. |
| Finished dimensions | Over-top span, row length, side drops, end coverage and any shaped panels | Approve a finished-size drawing with seam and hem allowances accounted for. |
| Color & surface | Grey / silver examples shown; other colors and finishes subject to material selection | Confirm sample color, outer face and surface finish. |
| Outdoor exposure | Storage location, solar exposure, season, expected reuse and cold-weather handling | Request UV and temperature evidence relevant to the selected grade; agree on any warranty in writing. |
| Edges & attachments | Reinforced hems, loops, grommets, rope hems or pockets as agreed | Specify spacing, orientation, corner build-up and included accessories. |
| Supply format | Finished hay covers; material or panel supply where suitable for a fabricator | Confirm what is fabricated, packed and supplied with each unit. |
| OEM & packaging | Branding, labels, fold orientation, unit packing and export packing requirements | Approve artwork, packing details and identification of the outer face. |
| Sample, MOQ & lead time | Confirm with DERFLEX after material, size, quantity and customization review. | Agree on sample scope, order minimum, production schedule and delivery terms in the quotation. |
Check a sample of the proposed cover construction, not only a small swatch. Agree on the inspection criteria before production.
Finished area, fabric construction, GSM, joining work, reinforced edges, hardware, order quantity and packing affect the quotation. Compare the same finished specification and delivery basis across suppliers.
Ask for test methods and results for the actual quoted fabric when comparing tensile, tear, UV or attachment performance. A general brochure claim is not a grade-specific acceptance criterion.
DERFLEX product and application photographs show finished PE cover details, outdoor hay storage and PVC coated material options. Confirm your own product against its approved sample and drawing.
Covering and keeping bales away from ground moisture both help protect dry hay. University extension guidance stresses the storage base, drainage and air movement. A waterproof sheet addresses only part of that system.
Material selection, fit and storage conditions decide how a hay cover performs. Use these questions to prepare a more precise inquiry.
Choose the actual grade around the storage period, exposure and handling. PE is a practical option for seasonal hay covers where weight and cost matter. PVC coated polyester is worth reviewing for repeated handling and custom fabrication. Compare UV evidence, seams, reinforcement and finished weight before approving either material.
Standard PE laminated and PVC coated weather covers should not be assumed breathable. Plan air movement through the storage layout rather than sealing the stack. If you need a breathable hay cover, request measured water-vapor and rain-resistance data for that specific product.
Measure the actual covered profile from one planned finished edge to the other, including side drops, and record the stack or row length plus end coverage. For round or multi-tier stacks, measure over the curved profile. Send a sketch and confirm finished dimensions rather than ordering from the ground footprint alone.
Use a cover with suitable reinforced attachment zones and a distributed tie layout matched to the site. Specify grommet, loop or pocket placement, protect abrasion points and review anchor requirements. Recheck tension after wind or stack settlement. Fabric weight alone does not define a wind rating.
A waterproof cover can reduce direct rain exposure, but it cannot guarantee mold-free hay. Moist hay, ground moisture, poor drainage, condensation and inadequate air movement can still cause spoilage. Use properly dried hay, a suitable base and an appropriate storage layout.
A weather tarp is not a hay-drying system. Confirm that the hay is suitable for dry storage using guidance for your forage and bale type. Excess moisture can cause heating and spoilage. Baleage uses a separate controlled wrapping process and should not be confused with a dry-hay storage cover.
DERFLEX supports custom hay cover specifications, including dimensions, material, color, reinforced edges and OEM requirements. Send the stack layout, intended storage period, quantity and destination. Sample availability, MOQ, production lead time and delivery terms must be confirmed for the actual order.
Source hay bale covers for farm use, wholesale distribution or a private-label product range. Ask DERFLEX to review the material, finished size and reinforcement together.
