Galvanizing Service


b-article-galvanis

 

Galvanized steel can be maintenance-free for many years. Thus, from an economic view, the initial cost of galvanizing is much less than the cost of repetitive maintenance over the life of the steel structure.

 

As the Indonesia economy continues to mature and becomes more competitive, the construction industry must also match today's increasingly more sophisticate markets and customers. In response, PT. Bukit Terang Paksi Galvanizing, was established in early 1997, to fulfill the demand for galvanizing services. With proven experience, technology, and commitment, PT. Bukit Terang Paksi Galvanizing is an indispensable asset for Indonesian industrial development.

Galvanizing Advantages :

• Galvanized steel can be maintenance free for many years
• From an economic point of view, the initial cost of galvanizing is far less than the cost of repetitive maintenance over the life of the steel structure.
• Galvanized steel components are practical to use and easy to process – they can be drilled, cut, welded, and painted.
• Chemical preparation ensures all surface are clean.
• Hot dip galvanizing coats all external and internal surfaces, edges, and crevices with an uniform envelope coating.
• Hot dip galvanizing is self-inspecting. The coating will not from on poorly cleaned surface.
• The hot dip galvanizing coating is harder than mild steel and can be handled, erected, or installed without repair.
• The hot dip galvanizing coating will cathodically protect any steel exposed through damage or cutting.

Galvanizing Process :
Hot Dip Galvanizing is a thermal process of coating steel products with a layer of zinc. Through this process, steel can become stronger and corrosion resistant, thus requiring less maintenance over the life of the products. Galvanizing offers steel products resistance to impact and abrasion, whilst providing cathodic protection. Because of this galvanizing is essential for the maintenance of steel no matter what shape or size.

The galvanizing process is as follow:
1. Hot caustic degreasing (removal of oil, organic materials and paint).
2. Hydrochloric acid pickling (removal of rust and mill scale)
3. Rinsing (removal of acid residues)
4. Pre-fluxing in solution of zinc ammonium chloride (surface conditioning)
5. Hot Dip Galvanizing (total immersion n molten zinc at 450 degrees Celsius)
Quenching (cooling and passivation of the zinc surface to prevent early oxidation)
