Hot-dip Galvanized Hollow Section Steel Tube A good quality steel metal tube is a primary requirement for manufacturing hot dip galvanized steel tubes. The metal is plunged in a bath of molten zinc, which adds an additional layer of zinc coating on these tubes.
Corrugated Galvanized Steel is commonly abbreviated to CGI and is a building material composed of hot-dip galvanizing mild steel sheets, cold-rolled to produce a linear corrugated pattern in them. The corrugations increase the bending strength of the sheet in the direction perpendicular to the corrugations, but not parallel to them.

Hot-dip galvanized surfaces are not generally tested in a salt spray test (see ISO 1461 [link by ed. to spec at TechStreet] or ISO 10684 [link by ed. to spec at TechStreet]). Hot-dip galvanizing produces zinc carbonates when exposed to a natural environment, thus protecting the coating metal and reducing the corrosion rate.
A square washer can be made of stainless steel, brass, steel, or other material, and may have a zinc finish or electro-galvanized plating for environmental protection. Square washers come in various dimensions and have inner and outside diameters designed to fit with specific sizes of bolts or screws.
