Predrilling our columns on our standard ranges makes the assembly of the cladding framework easier while preserving the structure's galvanization as well.
As a matter of fact this pre-drilling aims at avoiding you to drill the columns after the hot-dip galvanization is done since this can damage the zinc coating and turn the structure rusty.
Therefore, the cladding framework becomes easy to assemble and can be used to carry your steel sheets, sandwich panels, or wood walls (We do not provide the wood cladding. Nevertheless, our kit buildings are manufactured to easily carry such cladding).
