Double and single channel for 8mm Twin-Wall Polycarbonate
The channels fit the 8mm twin-wall polycarbonate well. Also easy enough to cut.
Channels were delivered with severe damage to at least five of the nineteen pieces ordered. Ends were bent and channels were crushed. There was no protective packaging used. The shipper, FedEx, took zero care to avoid damaging the material.

H panels and 8mm polycarbonate sheets
Ordered late summer and installed them in my greenhouse today. I underestimated how much I would need of the H panels but have complete confidence in ordering more. H panels and polycarbonate sheets arrived no problems.

H channel and end channel
Ordered 6 ft pieces and they arrived but must've encountered some rough handling as there are a few that are bent - I'm thinking (hoping) we can bend them back out so the polycarbonate panels will fit in the tracking.
