When choosing a grid, pay attention to its strength. Try to straighten the protruding darts. If the bend angle, without much effort, increases, then it is definitely from aluminum. About the life of operation, and about strength, you have already guessed yourself. The fortress (stiffness) of weaving plays an important role. How the darts of the upper and lower parts of the grid are bent — this factor can play an evil joke when fastening the grid to the supports. It can be columns, garage walls or other buildings. The material is sold by rolls of 10 m.
