Wind and dust control
A porous screen reduces wind speed rather than blocking it completely. That is what allows dust to settle instead of being lifted, and it is why the shade rate of the mesh matters more than its strength.
Also known as: Dust suppression net · Wind screen · Stockpile wind fence · Dust wall mesh
Typical range. Final dimensions, coating mass and tolerances are confirmed on the order drawing.
| Shade rate | 30%–95%, selected according to the wind and dust conditions |
|---|---|
| Wall height | 1–12 m in the standard range |
| Mesh material | HDPE flexible mesh, or perforated metal panels for rigid walls |
| Dust suppression | Typically 65%–80% depending on the shade rate and the site layout |
| Roll width | 1–6 m |
| Colour | Green, black, grey or a project colour |
| Support system | Steel posts, cables, clamps and foundations designed for the wind load |
| Note | Shade rate, height and spacing are set by the wind study, not by a catalogue default |
| HDPE mesh | Flexible, UV stabilised, supplied in rolls |
|---|---|
| Perforated metal panels | Rigid option for high or exposed walls |
| Posts and cables | Steel posts, perimeter cables and clamps |
| Fixings | Clamps, tensioners and foundation connections |
Typical configuration
H 6–12 m, shade rate from the dust study
Reduces wind speed across the pile face.
Typical configuration
H 8–12 m, coastal coating specification
Corrosion protection matters on coastal sites.
Typical configuration
H 3–6 m, relocatable system
Temporary screens that can be moved between phases.
Typical configuration
H 1–4 m, lower shade rate
Wind reduction for crop, livestock or storage areas.
A solid wall forces the wind up and over, which increases speed at the top and creates strong eddies behind it. A porous screen reduces the wind speed as it passes through, so dust is less likely to be lifted in the first place.
Shade rate is the proportion of the screen that is solid. A low shade rate lets more wind through with less reduction per unit; a high shade rate reduces wind speed more but increases the load on the posts and can create turbulence. The optimum depends on the wind climate and the material being protected.
The site location and prevailing wind direction, the height and length of the wall, the material to be protected, the local wind speed and the ground conditions for the foundations. These determine the shade rate, post spacing and foundation size.
