Woven Polypropylene Covers & Tarps

Woven polypropylene is the preferred outdoor cover material because it combines strength with breathability — two properties that sealed plastics cannot deliver together. Polyethylene stretch wrap and standard poly tarps trap moisture against the product surface, creating the warm, humid conditions that breed mould, mildew, and staining. For hay, that means lost feed value. For lumber, that means downgraded grade. For stored materials, that means corrosion and water damage.

Woven PP allows air circulation while still blocking rain, dirt, and UV. This breathability is especially critical for products that continue to release moisture after covering — green lumber, freshly baled hay, and freshly poured or stored construction materials. The woven flat-tape structure also delivers tear and puncture resistance that survives forklift tines, sharp edges, and the wind abrasion that shreds lightweight PE tarps within a single season.

Every woven PP cover spends its working life outdoors, exposed to direct sunlight. Without adequate UV stabilization, polypropylene degrades rapidly — losing tensile strength, becoming brittle, and tearing during handling. In Canadian and northern US climates, where product may sit in a yard for weeks or months, UV protection is a fundamental performance requirement.

Our covers are manufactured with HALS (Hindered Amine Light Stabilizers) compounded directly into the polypropylene resin before extrusion — not surface-applied where it wears off with abrasion. Standard UV stabilization uses a HALS additive package engineered for outdoor service. How long a cover holds up in service comes down to your latitude, sun intensity, and how long it stays exposed — for a specific spec we can provide the mill test report. For export yards, southern climates, or multi-season storage, we offer enhanced UV packages; tell us your region and exposure and we will point you to the right level.

The same core material covers every application — it's supplied on rolls and cut to length on site for the job at hand. Hay tarps roll out over round-bale stacks and silage piles. Pallet covers drape palletized goods in outdoor staging and transport. Construction covers protect material stockpiles, scaffold, and staging areas. Stockpile covers drape sand, gravel, and salt piles. Ground cover is the water-permeable grade for nurseries and landscaping. Lumber wrap is also available as tubular and half sleeves.

All share the same UV-stabilized, breathable woven PP base (PE-coated where waterproofing is needed). Standard supply is roll stock; custom widths, fabric weight, coating, printing, and finishing are available on request — submit your specs for a quote. If you handle more than one of these applications, a single material spec across formats can simplify procurement — ask about a combined supply program.
