Common Greenhouse Profiles:
1. Greenhouse Locking Profile (Locking Channel)
The locking channel—also known as the plastic fixing profile—is used to secure the greenhouse’s polyethylene covering onto the outer walls and within the center gutter. The plastic sheet is fastened using a spring wire (locking spring), which fits into the channel. The greenhouse locking spring is a UV-coated galvanized wire, available in 2 mm and 2.3 mm thickness and 2 meters in length. It holds the polyethylene firmly in place inside the locking channel.
2. Omega Profile (U Profile / C Profile)
Known as both “U” and “C” profiles, the Omega profile is made of galvanized steel with a thickness of 1 to 1.25 mm. It is commonly used for mounting polycarbonate sheets or polyethylene film onto the greenhouse frame.
3. H Profile (M Profile)
The H profile is a hybrid of the locking channel and U profile. It is used at the peak of the greenhouse roof to secure the polyethylene to the arches, reinforcing the structure. One side of the H profile is attached to the structure, while the other side can be used to fix shading nets or insect-proof meshes.
