Precautions for production
1. Thickness
The thickness of iron galvanized gutters ranges from 1.5, 1.8, 2.0, 2.2, 2.5, 3.0. The thickness of different materials in different regions and on the top is different. The thickness of the film conjoined greenhouse is generally 1.8, 2.0, the thickness of the glass multi-span greenhouse is generally 2.0, 2.2, and the top of the glass is generally 2.5. 3.0 Thickness Dimensions.
2. Zinc layer
The zinc layer is a matter of the service life of the gutter plate. The thickness of the galvanized layer varies from 80 grams, 100 grams, and 120 grams. The gutter is also the most difficult place for customers to distinguish between good and bad quality.
3. Bending angle
The problem of bending angle generally occurs in greenhouses covered by glass at the top, because the aluminum alloy of the top girder needs to be cut according to the angle of the gutter, so the cut must match the gutter. If it does not match, it will be very difficult to install later.
