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. NettetHDG stands for Hot Dip Galvanizing and the number (either 600 or 900) stands for the coating thickness measured in grams per square meter. You can convert grams per square meter to microns by dividing the g/m2 by 7 (eg 900g/m2 / 7 = +- 125microns). The HDG600/900 comes from a standard called AS2312.

NettetThe continuous hot-dip galvanizing process offers a wide protection range from Z100 to Z600 in addition to a tight bond between the coating and the steel.
