Plastic trellis is an extrusive plastic mesh of HDPE or polypropylene. This plastic netting can be divided into two types - light duty and heavy duty, according to the wire gauge. The light plastic trellis has reach-through opening which simplify tending and harvesting in harvest season. For the heavy trellis, its square opening is 2 inch wide. It is excellent for peas and pole beans. In addition, heavy duty trellis can also be used as garden fence to block chicken and cat out.

Similar to nylon and knitted polypropylene netting, plastic trellis is usually used with stakes, poles, rebar or T-posts, all of which can provide support for the trellis netting. Zip-tie and trellis clips are also provided on special order.
