| Airflow |
Strong choice when ventilation is needed. |
Blocks airflow and creates a sealed surface. |
Choose mesh for heat relief, greenhouse shading, fencing and dump truck loose loads. |
| Water protection |
Not suitable for full rain blocking because water passes through the open structure. |
Better choice for waterproof protection when fabric and seams are correctly specified. |
For water-sensitive goods, specify solid PVC tarpaulin and discuss welded seams. |
| Wind load |
Allows air through and can reduce ballooning under exposed conditions. |
Can catch more wind if installed without proper tension and reinforcement. |
Large covers need careful grommet spacing, webbing, corner patches and fixing design. |
| Sun and shade |
Filters sunlight while keeping air moving. |
Provides stronger sun blocking and full surface coverage. |
Mesh openness should be selected according to shade, privacy and airflow targets. |
| Debris control |
Works well for leaves, light waste, mulch, gravel, construction debris and visual screening. |
Works better when small dust, rain, mud or contamination must be blocked. |
Send particle size, load type and route condition for truck tarp recommendations. |
| Truck and trailer use |
Common for dump trucks, landscaping trailers and loose loads that do not need dry coverage. |
Common for flatbed, cargo, machinery, lumber, steel, agriculture storage and long-haul covers. |
DERFLEX can discuss mesh/vinyl combinations for fleet programs. |
| Finished fabrication |
Reinforced hems, grommets, webbing, rope edges and pockets are important for tension. |
Welded seams, reinforced hems, D-rings, straps, rope-in-hem and corner patches may be used. |
Do not finalize by fabric only; confirm the complete tarp construction. |
| Purchasing cost direction |
Often economical for shade and airflow applications, depending on weight and reinforcement. |
Usually higher material coverage and coating requirement, depending on GSM and finishing. |
Compare total service value, not only unit price per square meter. |
