NettetPut the correct vent and drain holes in hollow steelwork. Being a dip process, galvanizing will protect the inside of steel sections as well as the outside – providing these holes are in the right places. These holes are essential for safe and effective galvanizing – so the galvanizer will have to put them in – which takes time.
