HOT DIP GALVANIZING HAS MANY BENEFITS FOR THE SPECIFIER
CORROSION RESISTANCE
-
Galvanized coatings protect steel in three ways:
1. The zinc weathers at a very slow rate giving a long and predictable life.
2. The coating corrodes preferentially to provide sacrificial protection to small areas of steel exposed through drilling, cutting or accidental damage.
3. If the damaged area is larger, sacrificial protection prevents sideways creep which can undermine coatings.
COATING TOUGHNESS
-
Galvanizing is unique. The process produces a coating which is bonded metallurgically to the steel.
COMPLETE COVERAGE
-
All parts of the surface of the steelwork are coated - external, internal, awkward corners and areas with narrow gaps.
RELIABILITY
-
Specified to a single standard
BS EN ISO 1461
SPEED OF APPLICATION
-
Can be applied in minutes
FASTER CONSTRUCTION
-
No site surface preparation is necessary
LOWEST LIFETIME COST
-
Competitive initial cost and long life make hot dip galvanizing the most versatile, economic method of protecting steelwork.
LONG LIFE
-
Often exceeding 50 years
EASE OF INSPECTION
-
The nature of the process is such that if the coating looks continuous and sound, it is so.
COMPETITIVE FIRST COST
-
For many applications the cost is lower than alternative coatings.
