Product Description
The galvanising process has a number of stages, all by immersion, that are required to achieve the final finish:
Acid or alkaline-based proprietary products may be used and they may be heated or used at ambient temperatures.
This is done in dilute hydrochloric acid which dissolves rust and produces a chemically clean surface.
A mixture of zinc chloride and ammonium chloride in solution is the standard agent of choice. The steelwork must be dry on completion of this stage.
The final stage involves the clean metal being immersed in a special bath of molten zinc at 450°C where the zinc alloys with the iron in the steel to form zinc/iron alloy layers. These layers are the basis of the coating.
At Jacksons Fencing, polyester powder coating can be applied if required after galvanising to protect the steel from rusting which allows the steel to not peel off with the paint still stuck to it. For installations near coastal areas, a marine coating can ensure that moisture does not get through to the galvanising below, helping to protect the finished product.
Even in cases where the initial cost of galvanising is higher than alternative coatings, galvanising is always cheapest in the long term because it lasts longer and doesn’t require constant care.
Galvanising offers complete coverage, sealing the base metal and stopping corrosion for good, eliminating the need for continual maintenance. The long-term durability is achieved at relatively low environmental burden.
Galvanising provides maximum protection through a tough, abrasion-resistant coating of increased thickness.
The lifespan of a zinc coating is largely determined by its thickness.
Data Sheet
Raw black pipes: all raw black pipes could be produced in our factory which could save your cost
Length: we can size for your requirements on length(it would take some more time);also we can welded it by automatic machines.
Thickness:from 1.0mm-5mm etc
Zinc weight: we can do according to customers' need,usually 70g/㎡
