hello everyone ,
i`m amatuer person from a poor country and i was searching for cheap materials to build the frame of my greenhouse . because materials as PVC pipes, metal pips, wood are expensive.
accedently i saw an image of metal racks while i was surfing facebook, then i got an idea to use the metal rods in my greenhouse.
i called a local supplier of the rods and i got the following information:
-these rods are called "slotted angle"
- every rod is 2 meters long , and you can request more length.
-thickness of metal is 1.5 mm and it is enough to hold moderate weights.
-rods are gelvanized (so they are protected against rust)
i asked him about the price ,and i was shocked when i knew it costs only 4 US dollars for every one hundred rods.
i called another local supplier and the cost was the same cheap.
i imagined to use these 100 rods to build my greenhouse, and i draw a sketch to illustrate my idea.
i hope to hear your opinion about the problems that i will face in this model.
i`m afraid the sharp metal angles will tear apart the plastic cover of green house, but i can buy tonns of cheap cloth to cover these angles and make it soft.
