Our history
DELTABLOC South Africa (Pty) Limited has emerged as a leading player in the road safety industry, addressing the shortcomings of traditional safety measures with innovative crash-tested vehicle restraint solutions. Founded in 2011, DBZA is a South African-owned company with partial shareholding by DELTABLOC International GmbH in Austria, an operating division of the Kirchdorfer Industries Group of Austria (established 1888).
Following the success of Delta Bloc’s temporary barriers in the Gauteng Freeway Improvement Project (GFIP), Delta Bloc branched out from their license partner to focus on DELTABLOC®️ as the Primary product in Southern Africa, to ensure unbending quality control, and introduce the full product range including permanent barriers systems and provide a wider range of safety barrier systems to all customers.
DBZA specialises in designing and manufacturing concrete and steel vehicle restraint systems and modern noise protection systems. For over 22 years, we have been supplying permanent and temporary safety barriers, noise protection systems, and steel guardrails to ensure a safe environment for road users.
