By People Who Know Steel.
Founded in 2000 by Connie de Lange and his eldest son Christiaan, Great North Structures has grown into a family-driven construction and steel fabrication company trusted across South Africa. In 2008, Connie’s younger sons — Johan and Francois — joined the team, turning GNS into a full family force.
Today, GNS delivers turnkey engineering, structural steel, and construction services across Limpopo, Gauteng, North West, and Mpumalanga — with a reputation for practical execution, reliability, and steel-strong workmanship.
