Grommeted Panel

The edges of these panels are sewn with heavy-duty reinforcing tape. Brass grommets are installed on approx. 2' centers around the perimeter. Often includes a seam where two pieces of shade have been sewn together. Durable, easy to install with ropes, bungees or wire. Most durable solution for smaller areas where shade will be suspended between four points. Grommeted panels are sold in pre-cut sizes or can be ordered in any custom size.

Precut Panel

A raw piece of shade fabric where edges of panel are not reinforced with any tape or grommets. Would not typically have a seam but may have a raw (cut) edge. Can be installed with wiggle wire, shade cloth clips or wooden lath. Precut Panels are sold in pre-cut sizes or can be ordered in any custom size.

Bulk (currently viewing)

Sold in factory widths by the linear foot. Would only rarely have a seam and sides typically include a factory finished (uncut) edge. Most cost effective solution for large quantities of shade fabric.

40% density blocks out 40% of light. Constructed of high density polyethylene, the tough lock-stitch design of this knitted material resists rips, tears and fraying while reducing wind speed and heat build up in structure.

  • Bulk shade cloth has an unfinished edge that does not include reinforcing tape or grommets.
  • Unlike woven shade cloth, the tough, lockstitch construction of our knitted material will prevent unfinished edges from unraveling.
  • Bulk shade cloth can be easily cut with a sharp pair of scissors to any desired size.
  • Bulk pieces can be attached using snap grommets, zip ties or other fastening methods.

Hanging Instructions

When hanging shade cloth pieces larger than 100 sq. ft., you may need extra center support to prevent the cloth from sagging in the middle. One easy way to do this is by running lightweight cable from corner to opposite corner, forming an X pattern that the cloth can rest on. For pieces larger than 400 sq. ft., you may need cables running end to end every 4' or so.

  • great sturdy shade cloth
    I planted late due to moving, and it's scorching hot now, so this shade cloth is up over my sweet potato/root crop bed. It works wonderfully and does well in the wind. Very sturdy and will last a long time.
  • Strong Reliable Cloth
    This cloth is much better than the cloth that I bought from Home Depot. This cloth is thicker and stronger than HD's cloth. My only regret is not buying a larger quanity.
  • good summer cover
    This shade cloth is lightweight and easy to drape over hoops. It worked well to keep cool- loving crops like lettuce happy during this summer's record- breaking heat wave. It seems like a strong material that will last many years.
  • Damaged
    One of the shade cloths arrived melted together and torn. Still awaiting a replacement.
  • I'm impressed.
    The order came much faster than anticipated. The measurements were spot on. And the price was very reasonable. I'll be ordering from them again no doubt.
  • Garden Plant Shade
    Material is just what I ordered and will work nicely keeping plants from burning up from sunlight.
  • A large purchase for a first time buying
    We were very impressed with this shade cloth but only rate it a 4 because the wind blew a hole in it on the SECOND DAY. Partly our fault because we used it to cover a 10'X10'X10' enclosure for a peach tree. The frame was metal pipe and it had a rough end, which caused the tear. Works GREAT for shade and birds!
  • Shade Cloth
    Just what the doctor ordered! Got it, and had it out in the garden in less than an hour! Works great! Plants are smiling now!!!
  • shade cloth
    Quality material at a real great price. I keep coming back to Megastore for my shade cloth and freeze cloth. Thanks
  • 40% shade cloth
    Very high quality shade. I like the fact you can customize the dimensions.
  • 40% Shade Cloth
    I purchased a custom cut 40% shade cloth with binding and grommets. I couldn't believe how fast it was made and shipped out. It fit my greenhouse perfectly. Excellent quality and price with double stitching on the binding and all grommets were placed between the two stitching seams. I am extremely pleased with my purchase. I highly recommend this business and product. Buy with confidence here. My plants should have a much easier time this summer in the super hot Florida sun. Thank you Greenhouse Megastore.
  • Shade cloth from Greenhouse Megastore
    What a joy to get my product! I expected far less than what I got. I ordered, what I thought would be un-sewn, un-grommeted rough cut fabric. (in fact, that what they said I would get).Instead, what I got was a very professional, durable shade cloth with both sewn and grommeted edges. Beautiful!Again, great service from this company. Best price, best service.
  • Greenhouse shade cloth
    Very good
  • Great Product!
    I live in southern Utah and the plants in my hoop house were struggling with the intense heat and sun until I covered the whole 24'x48' house with the 40% shade cloth. The plants recovered within a week!
  • Shade Cloth, 40% Black
    Last year I made mini hoop-houses using shade cloth in order to grow broccoli and other heat sensitive vegetables, all with good results. This year I constructed a large hoop house and covered it with 40% shade cloth. I've noticed that it is definitely cooler under the shade cloth, keeps the grasshoppers out, less water usage, and is pleasant to do garden work with the shade cloth. Need to figure out a way to allow pollinating insects to get to the plants as the entire hoop-house is covered with shade cloth.The shade cloth also protects the plants from hail storms that seem to come out of nowhere in these parts. I highly recommend this product.
  • Shade cloth and grommets
    Order both 40% and 60% knitted shade cloth in 6' width. 60% appears to be 2 pieces of 3' width sewn together. 40% is two layers of 20% sewn at one end. Not sure why, maybe it's what had to happen to fill the order. Plastic grommets have a hard time with double layer when using the 40% but I like them because I can seperate them with breaking unlike the Home Depot grommets.
