Hot dipped Galvanized Temporary Fence Panels

Hot dipped galvanised temporary fence panels are processed by immersing in a bath of molten zinc to produce a corrosion-resistant, multi-layered coating of zinc-iron alloy and zinc metal. While the steel is immersed in the zinc, a metallurgical reaction occurs between the iron in the steel and the molten zinc. Hot dipped Galvanized temporary fencing with a minimum of 20 years of service life, whether in New Zealand or Australia.

What is a hot-dip galvanising temporary fence?

The longevity of temporary fence panels service life is surpassed 20 years + the whole temp panels dipped zinc hot-dip galvanising temporary fence (HDG) is a process in which prefabricated black steel temporary fence panels are immersed in a molten zinc bath for coating treatment. There are three basic steps in the hot-dip galvanising temporary fence process; Surface preparation, galvanising and inspection

surface treatment

When the assembled black steel temporary fence panels reach the galvanising facility, it is suspended or placed in the shelf system with black steel temporary fence panels wire. The shelf system can be lifted and moved in the whole process by a bridge crane. Then the black steel temporary fence panels go through three cleaning steps; Degreasing, pickling and flux. Degreasing can remove dirt, oil and organic residues, while an acid pickling tank can remove iron oxide scale and iron oxide. The final surface treatment step, flux, will remove any remaining oxides and apply a protective layer on the black steel temporary fence panels to prevent the formation of oxides before galvanising. Proper surface treatment is essential because zinc does not react with dirty black steel temporary fence panels.

Galvanized

After surface treatment, immerse the black steel temporary fence panels in a molten (830 f) bath containing at least 98% zinc. The black steel temporary fence panels are placed in the kettle at an angle so that air escapes from the tubular or other pockets and zinc flows in, through and through the whole workpiece. When immersed in the kettle, the iron in the black steel temporary fence panels reacts with zinc to form a series of zinc-iron intermetallic compounds and pure zinc outer layers.

inspect

The final step is to check the coating. The coating quality can be determined very accurately by visual inspection because zinc will not react with dirty black steel temporary fence panels, which will leave uncoated areas on the parts. In addition, a magnetic thickness gauge can be used to verify that the coating thickness meets the specification requirements.

Coating benefits

hot-dip galvanising temporary fence provides many benefits for the black steel temporary fence panels it protects. Metallurgical bonded Zn Fe alloy layer forms a barrier between black steel temporary fence panels and the environment and can cathodic protect black steel temporary fence panels. The cathodic protection provided by zinc means that the zinc coating sacrifices itself to protect the underlying base black steel temporary fence panels from corrosion. Since the intermetallic layer is more complicated than the base black steel temporary fence panels, a tight coating with a bond strength of about 3600 psi also has very high wear resistance (Fig. 2). However, even if the coating is damaged, the sacrificial effect of zinc will protect the exposed black steel temporary fence panels for up to ¼ Inches. In addition to the cathodic protection provided by hot-dip galvanising, the coating has some other characteristics to prolong its service life. First, the reaction in the galvanising kettle is a diffusion process, which means that the coating grows perpendicular to the surface to ensure that the thickness of all corners and edges is at least equal to the plane. In addition, complete immersion in the zinc bath can completely cover the black steel temporary fence panels, including the interior of the hollow structure. Finally, the zinc coating naturally forms an impermeable corrosion product on the surface, called zinc copper green. Copper green, cathodic protection, full coverage, and other features give hot-dip galvanised black steel temporary fence panels an extended maintenance-free service life.
