Hot Dip Galvanizing
The simplest way to protect your projects
Hot-Dip Galvanizing in Oradea
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:
