Test & Inspection

Our products are manufactured using the Electric Resistance Welded production system (ERW). We consistently develop and improve our production procedure, in which every process has to be inspected thoroughly by our skilled engineers starting from coil inspection to finished goods certification. This is to mark sure that our products are fully complied with the standards.
