Hot-dip Galvanizing Production

Our hot-dip lines offer a choice of horizontal or vertical non-oxidizing type furnaces. The furnaces can be sized purely to provide a clean surface for optimum adhesion of the zinc coating. Or, they can be designed to also anneal strip of various grades from full-hard to deep drawing quality.

RIAMB's lines offer a very wide range of features :

>> Highly automated entry and exit sections that ensure efficient coil handling.
>> Vertical or horizontal strip accumulators.
>> Turret-head edge trimmers.
>> Fixed or shuttle-type scrap choppers.
>> Prep-lap, limited overlap or flash-butt welders.
>> Acid pre-cleaning sections.
>> Steel or ceramic galvanizing pots. These can be of the single-, dual-, or triple-shutter type.
>> Elevating pots are also available for use with fixed furnace snouts.
>> Air or nitrogen coating knives.
>> Mini and zero spangle fixtures, using steam, water/chemicals and zinc dust.
>> Galvanneal furnaces.
>> Closed-loop coating weight gauges for controlling coating thicknesses.
>> Dip, spray and coater-type passivating systems, including resin coaters.
>> Tension-levelling sections and skin pass mills.
>> Level 1, 2 or 3 electrical control systems.
