Fastener Coatings & Surface Treatments

The right fastener grade and the wrong coating will still fail in service. In aggressive environments — offshore platforms, GCC coastal structures, petrochemical process piping, desalination plants — coating selection is as critical as material selection. Asia Bolts Industries operates an in-house surface treatment facility at our 32,260 sqm Dubai Investment Park complex, capable of hot-dip galvanizing to ISO 1461, zinc electroplating to ASTM B633, PTFE/Xylan coating, Dacromet, Geomet and black oxide finishing — eliminating the 3–7 day lead time penalty of outsourcing to external coating facilities. Every coated fastener is supplied with a coating thickness certificate, dimensional compliance report and full material traceability from raw bar to finished, coated fastener.
