Hot-Dip Galvanized (HDG)
Metal parts are immersed in molten zinc to form a thick, durable zinc layer.
Benefits:
-
Excellent corrosion resistance
-
Long service life (20–50+ years depending on environment)

-
Ideal for outdoor structural use
Cold Galvanized
Zinc-rich paint applied via spray or brush.
Benefits:
-
Cost-effective
-
Suitable for indoor or mild environments
-
Good weldability maintenance
Shot Blasting
Steel surfaces are cleaned using abrasive blasting to reach Sa1–Sa3 standards (ISO 8501-1).
Benefits:
-
Removes rust, scale, old coatings
-
Improves coating adhesion
-
Achieves required surface roughness
-
Essential pre-treatment for FBE/3PE/3PP coatings
Black Coating
A uniform protective black varnish or black epoxy coating applied to steel pipes.
Benefits:
-
Prevents rust during storage and transportation
-
Smooth appearance
-
Widely used for mechanical pipes, structural tubes, round and square hollow sections
FBE Coating
A single-layer powdered epoxy coating applied by electrostatic spray and cured at high temperature.
Features & Advantages:
-
Excellent chemical resistance
-
Suitable for buried and submerged pipelines
-
High adhesion to steel
-
Low permeability
Applications:
Oil & gas pipelines, water pipelines, offshore and onshore pipeline systems.
