Big Omega Profile 5.0m for Base Greenhouses 30mm Large Omega Profile is designed for your greenhouse, so that in a simple way you can fix the meshes and plastics to its structure together with the polyethylene slat. For purchases of less than 50 profiles, the bars are sent cut (2.5 m. Each) to lower the cost of transport. In any case, you can consult our commercial department. If you need to do a complete installation, in addition to the profiles, you would need OMEGA BIG JOINT (to join the profiles, 2 per 5m profile) + OMEGA BIG POLYETHYLENE STRIP (to block the plastic or mesh, 2 per 5m profile) + SCREWS M-8 x25 and NUT M-8 (4 units of each per Profile of 5m.) These items are listed above. IN OUR BLOG YOU CAN FIND VIDEOS AND PHOTOGRAPHS OF INSTALLATIONS OF THIS MATERIAL.
