plastic h profile
Easily cut with a fine toothed circular saw blade. Firmly holds the polycarbonate panels together. I only used 2 pieces in the construction of a coldframe and they worked great. They did arrive very scuffed up, as if they had been sitting on the warehouse floor for awhile. Overall a good product.
H-profile worked well joining 6mm polycarbonate.
Just what I expected
Arrived timely and whole, fit well, installed well.
Handy to have
The H channels are very handy to join 2 pieces together. A little hard to get together, but nice and snug once you do get them on.
Not to great
All connecting pieces shipped scratched
Other use for this 'H' Channel
I used 2x4' polycarbonate panels for my pool's solar heater array. In addition to using 4' sections of 'H' channel between panels, I used them as 2' long attachment points along the top edge by sawing off the top two arms of the 'H' to make the pieces 'U' shaped, and attaching each piece at the top with a single screw through the center square piece of the 'U'. These made very sturdy brackets for holding the top edge of the panels. The panels and trim pieces all cut very easily on my table saw using a diamond cutoff blade. Excellent product. It remains to be seen how durable they will be in this environment. (Pictures available if you wish.)
This is my first experience with polycarbonate on a greenhouse so I can't really compare this product to anything else. What I say is that this H channel seems well made and is sturdy. Hugs the panels tightly. Was easy to attach to the wood frame on the greenhouse.
The Best and the Worst!
So, these things work great once they are together - but it is the getting together that is the problem! I had to use lubricating oil and slide the entire panel down the profile piece! They snap easily to one end, but it is getting the next panel that is a pain in my shoulders, and my back, and my hips, and oh yeah my neck too! If you try to do it the logical way and push them together: GOOD LUCK! It's impossible because there is always a small lip somewhere along the length that catches and prevents it from popping in. Maybe this was supposed to be a two person job? But it definitely is not for one person! Hope to buy many more next spring!!! Lessons have been learned and I will buy more because like I said, it works great once together!
