Onion mesh is a fencing material that does one thing well. It creates a temporary barrier that people can see and trust, and it does so without costing much or taking long to put up. The name comes from the weave pattern, and the product itself is made from 100 percent virgin HDPE with UV protection built into the material during production. That means prolonged sunlight does not turn it brittle or wash out its color the way it would with cheaper alternatives.

Weights run from 40 to 120 gsm, so you can pick a lighter roll for quick setups or a heavier one when the barrier needs to take more punishment. The standard look is orange with red and bright yellow bands woven through the mesh. Those bands are not decoration. On a busy site where machines are moving and workers are focused on their own tasks, a barrier that catches the eye is a barrier that does its job.
Installation is where onion mesh really earns its keep. Heavy duty ropes run along the top and bottom edges, so the mesh ties straight onto support posts without tools or special fittings. That design keeps setup time short and teardown even shorter. You will see it on construction sites containing debris and dust, wrapped around scaffolding as a protective enclosure, and along temporary guardrails. Industrial plants and refineries use it during maintenance turnarounds when work zones need to be marked off fast.
Standard sizes include 0.9 by 50 m, 1 by 50 m, and 1.5 by 50 m, and custom dimensions are available. For anyone who needs a low cost, UV resistant barrier that goes up without hassle, this mesh is a straightforward answer.
