This is the 40GSM shade cloth netting we supply for greenhouse crops. At 40 grams the cloth is light enough to roll and re-hang with one pair of hands, and that is what makes it the choice where the cover is adjusted through the season rather than fixed once. The three needle knit gives the mesh a sturdier edge than a flat weave at the same weight, so it holds its shape on a frame and does not tear at the fixings. It suits a vegetable house and a garden bed alike, and the shade rate is made to order from 30 to 95 percent.
Weight decides how a shade cloth handles on site, and 40GSM is the band where a cover is still easy to roll and re-hang by hand. This is the light three needle shade cloth netting we supply for greenhouse crops, from a knitted HDPE mesh made to order across the shade range.
At 40 grams the cloth is light enough that one person can handle a house roll, which matters where the cover is adjusted through the season rather than fixed once. A light cloth also puts less load on the frame, so a tunnel or a hoop house that was not built for a heavy cover still carries it without extra bracing. The mesh stays open, so air moves under the cover and rain reaches the beds rather than sitting on the cloth.
The three needle structure means the mesh is knitted across three needles rather than a single flat weave, which gives the cloth a sturdier edge and a denser cover at the same weight. It holds its shape on a frame and does not pull away at the fixings, which is what a light cloth usually fails at first. The roll does the vegetable house and the garden bed alike, and growers running pots under the same cover often pair it with a planting bag, while the wider shade net range covers the heavier and coloured types where the job calls for something other than a light green cloth.

The rate is the first decision, and on this cloth it is made to order across 30 to 95 percent so the cover is set to the crop rather than the grower working around a fixed number. Roll length is the second, because the net has to cover the house or the bed rather than a single row. A knitted monofilament net covers the same idea where a finer weave is wanted, while this light cloth covers the standard vegetable house. Growers often hold one roll for the house and use the offcut on the garden bed.
Width, roll length, shade rate and colour are all made to order, so the first detail to confirm is the span of the house or the bed and the weight you want to handle. Rolls ship in export packing and are cut to suit the frame. Growers tracking how shade cloth performs across a season can follow trade coverage such as HortiDaily and FreshPlaza for what is being installed on commercial sites.
Why choose 40GSM rather than a heavier cloth?
At 40 grams the cloth rolls and re-hangs by hand and puts less load on the frame, which suits a house or a bed where the cover is adjusted through the season.
What does three needle knit change?
The mesh is knitted across three needles rather than a single flat weave, so it has a sturdier edge and holds its shape at the fixings instead of pulling away.
Can I order a different shade rate?
Yes. The rate is made to order from 30 to 95 percent, so a lighter or heavier cover is produced where the crop calls for it. Tell us the crop and the span and we will advise.
Tell us the span, the shade rate and the colour you are working to, and we will confirm the roll length and the packing that suit your order.
