Hot Dip Galvanizing

The hot dip galvanizing, is a process for protecting iron objects from oxidation (rusting) for many years.


Hot Dip Galvanizing

More specifically, after making a deep cleaning irons by chemical or technical means, or both, are immersed in the reservoir fluid temperature zinc 460 ° C in order to form a zinc coating that is metallurgically bonded to the surface of irons. The hot dip galvanizing, is adaptable to almost all types of fabricated or non-iron objects such as wire, pipes of all types, tanks, large and small constructions with their accessories, and more.

The process of hot dip galvanizing is:


1. Syrmatoma (if required)
2. Degreasing (if required)
3.Dipping in the hydrochloric acid tank, lifting and dipping 2-3 times.
4. Dipping in the water tank
5. Transportation and dipping in FLUX tank for preparation of surfaces.
6. Στέγνωμα υλικών με θερμό ρεύμα προπανίου.
7. Εμβάπτιση στο τήγμα ψευδαργύρου.
8. Αποσυρμάτωση - καθαρισμός τεφρών και σταξιμάτων.
9. Επιθεώρηση πρόσφυσης στρώματος ψευδαργύρου σύμφωνα με την προδιαγραφή ASTM Α-153

The hot dip galvanizing is considered the best in its class and has many advantages. It has the lowest cost in the class and this is because the hot galvanizing achieve an effect lasting from 20 to 50 years with the minimum of maintenance, unlike other protective iron do not have such long life and maintenance free equal to the initial cost. The coating hot galvanizing has a structure that gives a special strength and automatic protection to any damages on the galvanized iron, which may occur during transport or installation.

The coating of hot galvanizing easily estimated by eye and may simply use a harmless method for thickness. Also, upon receipt of galvanized iron no valuable time is lost for inspecting or preparing them and placed immediately.
