Certified high-integrity structural fasteners, hex bolts, threaded rods, and nuts engineered for heavy industrial engineering and marine environments in Bangladesh.
As Bangladesh advances rapidly toward its target of becoming an industrialized nation by 2041, major infrastructure developments—including power plants, deep-sea ports, high-speed rail links, bridge construction, and chemical processing facilities—demand top-grade structural integrity. At the center of these heavy-duty assemblies lies a essential, non-negotiable structural element: Industrial Threaded Rods (All-Thread Rods / Stud Bolts). Choosing the correct metallurgical grade, thread profile, and surface protection coating is crucial to preventing structural joint failures caused by monsoon-induced corrosion, high thermal loads, and heavy cyclic vibrations.
We operate as a global manufacturer and premier exporter headquartered in Mumbai, India, delivering certified, precision-engineered industrial threaded rods, stud bolts, and custom fastener packages directly to project sites, contractors, and industrial distributors across Bangladesh, including Dhaka, Chattogram (Chittagong), Khulna, Mongla, Sylhet, and Gazipur.
Industrial threaded rods are full-length continuous threaded studs manufactured in accordance with strict international standard dimensions including DIN 975, DIN 976, ASME B18.31.2, and ASME B18.31.3. Based on operational demands, our inventory and custom manufacturing lines supply threaded rods across a broad spectrum of material grades:
The table below provides engineering teams, structural designers, and procurement managers in Bangladesh with a clear technical overview of standard threaded rod grades:

| ASTM A193 Grade B16 | M12 – M64 / 1/2" – 2.5" | 125 ksi (860 MPa) | 105 ksi (720 MPa) | 321 HBW max | Turbines, Boilers, Power Generation Plants |
| ASTM A320 Grade L7 | M10 – M64 / 3/8" – 2.5" | 125 ksi (860 MPa) | 105 ksi (720 MPa) | 321 HBW max | Sub-zero Storage, LNG Facilities, Refrigeration |
| ASTM A193 B8 Class 2 | M6 – M56 / 1/4" – 2" | 110 ksi (760 MPa) | 95 ksi (655 MPa) | 320 HBW max | Chemical Processing, Food Processing, Clean Rooms |
| ASTM A193 B8M Class 2 | M6 – M56 / 1/4" – 2" | 110 ksi (760 MPa) | 95 ksi (655 MPa) | 320 HBW max | Marine Infrastructure, Coastal Bridges, Desalination |
| Duplex UNS S32205 | M10 – M48 / 3/8" – 1.75" | 116 ksi (800 MPa) | 80 ksi (550 MPa) | 290 HBW max | Offshore Oil Rigs, Seawater Intake Systems |
Bangladesh features a tropical monsoon climate characterized by high annual rainfall, high relative humidity (frequently exceeding 85%), and intense marine salinity along the Bay of Bengal coastline (Chattogram, Cox's Bazar, Mongla, Matarbari). Unprotected carbon steel threaded rods experience rapid surface oxidation and corrosion in these conditions. To maximize service life, we provide high-performance anti-corrosion surface treatments:
Delivering field-tested, certified threaded rods for major infrastructure initiatives and industrial manufacturing hubs across Bangladesh.
High tensile ASTM A193 B7 threaded rods and HDG anchor bolts used extensively in bridge expansion joints, concrete pier tie-downs, guardrail posts, and overhead sign gantries across major transport corridors like the Padma Bridge Rail Link, Dhaka Elevated Expressway, and Bangabandhu Tunnel access roads.
Cr-Mo ASTM A193 Grade B16 and B7 threaded rods engineered for high-temperature steam lines, turbine casings, transformer anchors, and structural supports in projects like the Rooppur Nuclear Power Plant, Matarbari Ultra-Supercritical Coal Power Project, and Payra Power Hub.
Stainless Steel SS316L, Duplex 2205, and PTFE-coated B7 studs used for jetty construction, fender mounting systems, subsea piping, ship repair yards, and dockyard cranes located in Chattogram Port, Mongla Port, and Payra Deep Sea Port.
DIN 975 Class 8.8 and SS304 all-thread rods serving the Readymade Garments (RMG), spinning, dyeing, and washing factories in Gazipur, Narayanganj, and Savar for securing overhead machinery, wet-process piping systems, and heavy spinning machine bases.
Bangladesh’s rapid economic evolution has reshaped the national landscape for industrial procurement. With the setup of 100 Special Economic Zones (SEZs) coordinated by the Bangladesh Economic Zones Authority (BEZA)—such as the Bangabandhu Sheikh Mujib Shilpa Nagar (BSMSN) in Mirsarai—foreign direct investment (FDI) and local manufacturing capacity are accelerating unprecedentedly.
Key market drivers impacting fastener demand include:
As a specialized manufacturer and global exporter situated in Mumbai, India, we offer strategic logistical, metallurgical, and economic advantages to buyers, importers, and contractors throughout Bangladesh:
Direct maritime shipments from Nhava Sheva (Mumbai) to Chattogram (Chittagong) or Mongla ports take significantly less transit time compared to European or Western suppliers, ensuring tight project deadlines are met without delay.
Our facility houses advanced testing infrastructure including Optical Emission Spectrometers (OES) for chemical analysis, Hydraulic Tensile Test Equipment, Hardness Testers (Rockwell/Brinell), Charpy Impact Testers, and Coating Thickness Gauges.
Every batch of threaded rods and stud bolts undergoes individual heat-number stamping. Each shipment includes full EN 10204 3.1 chemical and physical test certificates traceable to raw material billet mills.
We supply standard 1-meter, 2-meter, and 3-meter threaded bars alongside custom cut-to-length stud bolts featuring rolled UNC, UNF, Metric Coarse, or Metric Fine threads matching exact engineering drawings.
Addressing common queries regarding international trade terms, customs clearance, payment options, and quality documentation for industrial threaded rods imported into Bangladesh.
We work regularly under Irrevocable Letter of Credit (L/C at sight) issued by top-tier Bangladeshi banks (such as Eastern Bank Ltd, City Bank, Prime Bank, Sonali Bank, or Standard Chartered Bangladesh) complying with Bangladesh Bank guidelines. We also accept Telegraphic Transfer (T/T) for smaller batch deliveries.
Most ocean container shipments (FCL and LCL) are routed directly from Nhava Sheva (Mumbai) to Chattogram Port (CGP) or Mongla Port. For urgent inland shipments, land transport via Benapole / Petrapole border customs points is available.
Yes. We coordinate seamlessly with globally recognized independent third-party inspection agencies such as SGS, Bureau Veritas (BV), Intertek, or Lloyd's Register to conduct pre-shipment inspections, quantity verification, and mill certificate validation prior to container loading.
Direct ocean freight transit time from Mumbai (Nhava Sheva) to Chattogram Port typically ranges between 7 to 12 days depending on vessel scheduling. Manufacturing lead time varies depending on batch size, specialized heat treatment, or coating requirements.
Threaded rods and all-thread studs of iron or steel are typically classified under HS Code 7318.15.00 (Other screws and bolts, whether or not with their nuts or washers). Stainless steel variants are classified under corresponding subheadings.
Yes. Our industrial threaded rods consistently pass tensile, yield, elongation, and chemical composition testing conducted by BUET or BSTI (Bangladesh Standards and Testing Institution) laboratories upon arrival for project site clearance.
