Another installation method does not need to make a concrete foundation in advance, this installation method is to excavate the embedded pit on the ground according to the position of each column during on-site construction (generally the embedded pit is 20*20*30mm square hole), and then put the column into the corresponding embedded hole, straighten it and fill the reserved hole with cement mortar.The crossbar of this zinc steel fence generally has two connection and fixing methods, one is that the crossbar is connected to the column through a special U-shaped connector, and the other is not to use the column, and the crossbar is directly buried in the masonry wall stack during installation, and the depth of the crossbar buried in the wall stack is generally 50mm.
