Production of Steel & Galvanized Pipes
High-quality ERW black steel and hot-dip galvanized pipes manufactured in Ghana to international standards.
Product Overview
Enginmac Technologies Limited manufactures premium Electric Resistance Welded (ERW) black steel and hot-dip galvanized steel pipes at our state-of-the-art facility in Spintex, Accra. Using advanced CNC roll-forming and high-frequency welding technology, we produce pipes with perfect roundness, uniform wall thickness, and superior weld integrity.
Our galvanized pipes feature a thick zinc coating of ≥500 g/m² (≈70+ microns), ensuring exceptional corrosion resistance for water supply, structural, and industrial applications across Ghana and West Africa.
