Ideal Protection For Your Equipment

Fire zincification is a process to protect iron and steel pieces and equipment against corrosion, coating them with a strong zinc layer, through a cast zinc immersion.

Agriculture: irrigation, machinery, drinking vessels, basins, stables.

Domestic Devices: buckets, heaters, grids, fences, nails.

Civil Construction: metallic structures, iron for concrete.

Electric Energy: high tension towers, ironware, radiators, poles/light.

Mechanical Industry: transporters, pulleys, recipients.

Mining: pipes, profiles, transporters, cars, washers, baskets.

Transportation: Roads: bumpers, gas stations, truck bodies. Railways: gas stations, fences, portals, refrigerating wagons. Maritime: ship pipes, fans.

Industrial Refrigeration: condensers, evaporators, ice generators, freezers.

General siderurgy: pallets, containers, raised platforms and several metallic structures.

Zinc Layer System

The zinc/iron alloys formed during the zincification process are coated by a pure zinc layer (solidification layer) at the moment that the pieces are withdrawn from bath, appearing in the surface the known zinc flowers. The resistance against corrosion of this zinc layer system is very high and varies between 8 to 60 years, depending on the environment where the objective lays.

Due to the formation of an insoluble zinc skirt (zinc patina) the iron surface coating is obtained, and it doesn’t rust anymore.

Process Description

Pieces that will suffer a zincification process have their surfaces conveniently prepared, so that, when they get in contact with cast zinc, there is immediate adherence. Necessary operations are:

• Degreasing
• Scouring (Chemical or Mechanic)
• Flow
• Zincification Itself

* Under continuous process for plate and wire. The zinc layer is of only 20 to 25 micron.

Advantages of Thermo Zincification

1. Due to the alloy of the cast zinc with the iron surface, a chemical reaction occurs in a system of closed layers, firmly adherent and of long durability.

2. Due to the diving process, all internal corners are protected, obtaining total coating.

3. High corrosion resistance due to high resistance of the several layers, especially in industrial environments.

4. Thermo galvanized pieces can only be welded with special electrodes.

5. The zinc layer is a safe ground for immediate or posterior painting.

6. Conservation expenses per year and per m² are extremely low in comparison to other protection methods.
