Galvanized Material

Galvanized material is steel material made from mixing materials or called as alloy steel. Those material is mix with zinc, material can mix on forming or just coated with zinc like on galvanized pipe. To coating material with zinc is called as Zinc immersion.

A basic zinc immersion bath that has performed well over the years consist of:

400 - 500 g/l NaOH
80 - 100 g/l ZnO

The process itself using hot dipping zinc material. Hot dip galvanizing of steel sheet (corrugated or otherwise) and of steel wire can be mechanized; galvanizing of fabricated parts is mostly done by hand. The parts must first be free from scale, rust and oxide; casting must be free from sand. This is mainly accomplished by pickling in acid, but large castings are sometimes shot-blasted or sang-blasted, followed by a lighter pickling process. It may be necessary to brush off detritus and residues adhering to the surface after pickling. The parts are then thoroughly rinsed and immersed in a fluxing solution, usually an aqueous solution of zinc ammonium chloride. They can held in this solution without danger of further oxidation or attack until required for galvanizing.

Likewise, proprietary sodium zincate solutions of this general type are available commercially and are capable of producing satisfactory result.

Unless otherwise agreed to between the purchaser and the manufacturer:
galvanized steel reinforced aluminum conductors shall be supplied in the manufacturer’s usual production lengths and with a permitted variation of ± 5 percent in the length of any one conductor length.

It shall be permissible to supply not more than 10 percent of the lengths on any one order in random length. Galvanized reinforced used on wire that used on construction material.
