Infrastructure & Construction
Rebar. Structural steel. Certified test reports for project compliance.
How QML Serves This Industry
Infrastructure and construction projects require material test certificates that demonstrate code compliance for every consignment of rebar and structural steel. QML issues independent third-party test reports for IS 1786 (TMT rebar) and IS 2062 (structural steel) that are accepted by PMCs, quality auditors, and government inspection departments across Tamil Nadu.
