Surface Coatings

Four Coatings.
Every Climate.

HRC
Hot Rolled Carbon Steel

The base material — hot rolled coil processed into tube. Suitable for indoor structural applications, fabrication, and products that will receive secondary treatment (paint, powder coat, galvanizing).

Base materialS235 / S275 equivalent
SurfaceMill scale finish
Best forIndoor, structural, fabrication
CRC
Cold Rolled Carbon Steel

Cold rolled for tighter dimensional tolerances and a cleaner surface finish. Preferred for furniture manufacturing, precision fabrication, and visible structural applications.

Surface qualitySmooth, clean — powder coat ready
ToleranceTighter OD/wall vs HRC
Best forFurniture, visible frames, precision
GI
Hot-Dip Galvanized

Zinc-coated for corrosion resistance. The standard coating for outdoor structural applications — construction, fencing, solar mounting, and agricultural equipment across Africa and the Middle East.

Zinc coatingAvg 45–85 µm (to EN ISO 1461)
Lifespan (outdoor)15–25 years typical
Best forConstruction, solar, outdoor structures
ZAM
Zinc·Aluminium·Magnesium

Premium tri-alloy coating delivering up to 10× the corrosion resistance of standard GI. Specifically engineered for coastal, humid, and high-salinity environments — ideal across the Gulf and coastal Africa.

Coating compositionZn + 6% Al + 3% Mg
vs standard GIUp to 10× better corrosion resistance
Best forCoastal, Gulf, solar, humid climates
