Material comparison at a glance
Material names describe a family, not a guaranteed performance level. Compare the finished specification as well as the base material.
| Material | Typical handling | Useful trait | Common fit |
|---|---|---|---|
| Polyethylene (PE) | Light to moderate | Easy handling, broad general use | Temporary covers, storage, weather protection |
| Vinyl / PVC | Moderate to heavy | Abrasion resistant, flexible, often repairable | Truck, industrial, repeated handling |
| Canvas | Moderate to heavy | Breathable; water resistance varies by treatment | Equipment, jobs needing less condensation |
| Mesh | Light to moderate | Air passes through; not waterproof | Shade, landscaping, load containment where approved |
Measure the object, then add coverage
- Measure the true footprint. Use the longest and widest points, including protrusions.
- Add the drop. For a three-dimensional object, include the height on both sides.
- Add working allowance. Allow for tie-downs, overlap, hems, and imperfect positioning.
- Round up carefully. A stock size must meet both minimum dimensions, even if rotated.
