GLOBAL QUALITY. LOCAL EXECUTION. THIRD-PARTY QA/QC FOR REFRACTORY ASSURANCE

CONFIDENCE THROUGH COMPLIANCE

In heavy industry, performance isn’t just expected — it must be proven. Whether supplying critical furnace linings to a copper smelter, rotary kiln, or steel ladle, DGC Refractories recognises that quality assurance isn’t a box-ticking exercise — it’s a contract of trust.

That’s why third-party QA/QC validation is a core feature of our refractory material supply model. We partner with independent, accredited testing laboratories to verify product compliance before materials are dispatched — ensuring clients receive only what has been specified, tested, and approved.

WHAT WE TEST — AND WHY IT MATTERS

Our QA/QC program includes:

• Chemical composition analysis to confirm purity and conformity with specification

• Bulk density and apparent porosity tests to validate insulation performance

• Cold crushing strength (CCS) and modulus of rupture (MOR) for mechanical integrity

• Dimensional verification to prevent joint misalignment during installation

• Thermal shock resistance and refractoriness under load (RUL) for furnace performance under stress

Each batch is accompanied by a comprehensive third-party inspection report, which is delivered transparently to our clients as part of the documentation package.

THE ROLE OF QA/QC IN ASSET INTEGRITY

Our clients operate in some of the most demanding industrial environments in Africa. In these contexts, unverified refractory materials can lead to:

• Premature lining failure

• Disruption to shutdown schedules

• Higher energy usage due to poor insulation

• Rework and unnecessary downtime

By embedding third-party QA/QC into every supply engagement, DGC Refractories reduces your operational risk — and strengthens the case for long-term performance-based partnerships.

ALIGNED TO INTERNATIONAL STANDARDS, DELIVERED WITH LOCAL ACCOUNTABILITY

Our QA/QC processes adhere to global standards, including ISO 12677, ASTM C134, and EN 993, among others. Yet what sets us apart is our ability to bridge these standards with regional expectations, combining global rigour with hands-on delivery oversight.

Whether you're operating in Southern Africa, the Copperbelt, or the Middle East, you can be confident that DGC’s materials arrive tested, certified, and compliant.

LET’S MAKE QUALITY MEASURABLE

 At DGC Refractories, we believe performance should be measurable, traceable, and independently verified.
