Hot Dip Galvanizing
The simplest way to protect your projects
Hot-Dip Galvanizing in Oradea
The Hot Dip Galvanizing Process
Our hot dip galvanizing vat with useful dimensions of L = 6.5 m; W = 1.1 m; H = 2.8 m ensures uniform galvanizing, in accordance with SR EN ISO 14001:2002. The end result is up to 80 years of protection for your product through the Zn-Fe alloy base coating, great adherence of the upper layer of Zinc with added protection from the Zinc oxide top layer and a minimal thickness of the coating that starts from 50 microns.
Clear communication and Same Day Pick-up
Our business is focused on customer satisfaction. In hot dip galvanizing, this means clarity in communication, promptness and same-day pick-up after scheduling in a fitting time with our process manager. We know you are on a schedule and need to finish work for your own clients quickly and at the highest standards. We are here to help you accomplish that and much more.
Environmentally-Friendly Technology
By using hot-dip galvanizing, 6000 million tons of steel are saved from rust worldwide, every year – this, in itself being a huge contribution to sustainable construction and the conservation of energy. Compared to emmissions-heavy painting, HDG is a much more environmentally friendly technology. We pride ourselves in doing our part to make construction a cleaner industry.
Technical Specifications
IMPORTANT: Please ensure the pieces you would like to galvanize correspond to the following technical specifications.
This helps us give you a perfect, fast result, every time, and protects you from incurring extra costs for the adaptation of the pieces to the hot dip galvanizing process through technical drilling or other mechanical processes.
The key to a good galvanization result
1. The pieces need to be designed in such a way as to allow for the liquid zinc to flow freely, this can also be done through creating ventilation orifices – see drawings
2. The pieces need to be clean from rust, vaseline/oils, welding slag or paints
3. Overlapping welded parts need to be avoided, can lead to deformation of the parts
4. Please avoid using materials with large thickness differences in the same part, as they show different expansion patterns in molten zinc, and this can lead to part torsion
5. Make sure your elements don’t have closed corners. They should allow zinc to enter through access openings in areas where there is material overlap.
6. A modular design is recommended, considering that large, complex parts must be dismantled before galvanizing, and thus an increase in transport and handling costs is also required.
7. The finished metal element will be immersed in a bath of liquid zinc at 450 Degrees Celsius. The expansion of the metal is inevitable, while its torsion is not, if: Welding stresses are avoided; Preferably, symmetrical sections are chosen; Possibilities for expansion are allowed in flat surfaces with pyramidal bars, radial ribs, etc.
8. Profiles with closed, unventilated parts can lead to deformation or even explosion in the galvanizing bath!
Please ensure that the section and the number of holes match at least the figures mentioned in the diagram:
