About Insimbi Freight

Insimbi Freight is RTG’s dedicated subcontractor transport division — purpose-built to scale capacity, increase agility, and maintain reliable service delivery during peak demand periods. 

The name “Insimbi,” meaning “iron” in isiZulu, reflects the core values that define us: strength, reliability, and durability. As a non-asset-based division, we leverage RTG’s national systems and infrastructure to coordinate and support over 500 vetted subcontractors — ensuring seamless overflow capacity for mining, agriculture, and industrial logistics.
