Certifications
Our hot-dip galvanising process is carried out in accordance with internationally recognised standards and supported by a comprehensive quality management system to ensure consistent and reliable coating quality.
Quality Control Throughout the Galvanising Process
Incoming Inspection
Material condition and venting requirements checked before processing.
Surface Preparation Monitoring
Treatment solutions regularly inspected and maintained.
Coating Verification
Elcometer testing conducted to verify coating thickness.
Final Inspection
Products inspected before release or re-galvanized where required.
Standards & Specifications
Hot-dip galvanizing is done in accordance to British Standard (BS EN ISO 1461: 2022), with minimum coating thickness requirements based on non-centrifuged sample averages.
