Fasteners Manufacturers in Vietnam for Refinery, Power and Manufacturing Growth
Vietnam’s industrial buildout anchored by the Nghi Son Refinery and Petrochemical Complex, the Dung Quat Refinery (Binh Son Refining and Petrochemical, BSR), PV Gas’ LNG import terminals, and a fast-growing coal and LNG-to-power pipeline is driving sustained demand for correctly specified, fully documented industrial fasteners. Jade Alloys is a fasteners suppliers in Vietnam partner trusted by EPC contractors, refinery-approved fabricators, and industrial distributors across Ho Chi Minh City, Hai Phong, and Vung Tau, supplying fasteners manufactured and tested at our own facility in Mumbai.
As an ISO 9001:2015 certified fasteners manufacturers in Vietnam businesses turn to for both standard and specialist requirements, we supply the complete range of industrial fasteners in Vietnam from workhorse hex bolts and heavy hex nuts for general industrial and construction use, to precision stud bolts engineered for Nghi Son and Dung Quat refinery flanged joints. Every consignment ships with EN 10204 3.1 Mill Test Certificates and full heat-number traceability from our NABL-accredited in-house laboratory.
What separates Jade Alloys from Vietnam-based re-exporters and regional trading houses is direct manufacturer access, no intermediary markups, full grade traceability, and the ability to manufacture to your exact drawing or project specification. Our Mumbai plant maintains a monthly production capacity exceeding 500 MT across all material grades, providing the production depth to fulfil both urgent site orders and long-lead bulk procurement contracts for bolts and nuts suppliers in Vietnam clients.
For Vietnamese clients with PetroVietnam, PV Power, EVN, or Samsung/LG electronics supply chain requirements, we provide NACE MR0175 / ISO 15156 sour service documentation where required, third-party inspection via SGS or Bureau Veritas, and all export documentation required for clearance at Cai Mep–Thi Vai Port and Hai Phong Port, including ISPM 15-compliant wood packing declarations.
