I do not quite understand the question, it affects my poor knowledge of the language...What do you call the plastic over the doors?? Pasha
The door I made with the help of electric welding of old metal tubes (or pipes... I don`t know the correct name of this... Tubes or pipes?) and scrap metal. Earlier water pipes were made of fairly thick-walled pipes, it spends a lot of steel. Now, these pipes are still to be found I found two such pipes and made them the door to the greenhouse (it no was used anywhere and was not rusty).. Then I drilled a lot of holes in it and took the nuts and bolts. One doorknob I fastened by electric welding, and the other doorknob fastened with bolts. Door hinges I picked up from an old broken and rotten couch that someone threw in the trash.
In general, at the door, I do not spend any money, using all the junk. But the door turned out robust and reliable. The truth is when I did it, I spent almost the whole day.
Level ground has some slope, so the foundation of the greenhouse with this side slightly elevated above the ground, and I have to pour a concrete staircase and entrance, where I could go with a wheelbarrow.
But I'm going to this later, now I'm still busy with the polycarbonate (plastic). Since it has not yet been charged conveying the film, so it is almost transparent. If it is removed, it will be similar to glass. And I still have to insert a lot of windows, for that, I'll take the old glass windows (they will can to be opened). I want to save a bit of polycarbonate. It is not too expensive, but I always count the money ))
