Explore the initial tier of our high-strength custom marine bolts and specialty alloys, engineered to endure the most hostile oceanic and atmospheric environments.
Modern marine engineering demands absolute structural integrity. Offshore drilling rigs, deep-sea vessels, oceanographic scientific installations, and harbor infrastructure are subjected to continuous dynamic loads, high-salinity seawater exposure, hydrogen embrittlement, and immense temperature fluctuations. In these unforgiving environments, standard off-the-shelf fasteners fail to provide the safety margins required. Custom ship bolt manufacturing is not merely a matter of dimensional variance; it is a meticulous process of advanced metallurgy, precision mechanical engineering, and rigorous compliance checks.
As a premier custom ship bolt exporter, our facility bridges the gap between scientific metallurgical research and practical heavy maritime construction. We specialize in producing custom bolts certified by the world's leading classification bodies. Our manufacturing techniques ensure that each bolt meets or exceeds standard criteria, maintaining fatigue strength, shear resistance, and structural longevity.
Established in 2015 in Shanghai, China, Beiersdorf Industrial Technology (Shanghai) Co., Ltd. has grown into a leading specialty enterprise focusing on high-performance fasteners and ultra-high precision components. Guided by the core philosophy that "Product quality is the foundation for an enterprise's survival" and maintaining an internal ethos of "Heart to sunshine, everything to prosperity", our team commits to zero-defect manufacturing.
Our technological infrastructure currently spans a state-of-the-art production base designed to support specialized custom processes. With an extensive range of close to 100,000 product models and more than 10,000 tons of finished stainless steel standard parts in stock alongside our raw material vaults, we guarantee seamless supply chain execution for both low-volume custom projects and large-scale maritime construction contracts.
M² Production Base
We push the limits of metallurgical engineering to support extreme physical dynamics, high thermal properties, and sub-zero cryogenic stability.
Designed for cryogenic storage tanks, LNG carriers, and aerospace fuel systems, ensuring absolute structural safety at liquid helium and nitrogen temperatures.
High-strength alloy systems engineered for high stress-bearing marine connections, resisting massive shear loads and pressure cycles.
Engineered using Nickel and Cobalt-based superalloys to maintain structural stability, creep resistance, and anti-oxidation under severe engine exhaust systems.
Our catalog offers 8 primary segments catering to marine, chemical, electronic, and high-precision machinery sectors.
Beiersdorf’s Shanghai production facility uses advanced manufacturing systems to deliver precision, traceability, and speed. Our manufacturing processes include automated multi-station cold headers, CNC high-precision thread rollers, and computer-controlled heat treatment furnaces. By integrating these systems, we eliminate human error during critical manufacturing steps, ensuring that every batch of ship bolts maintains consistent structural properties.
Our factory operation is built around "Supply Chain Resilience." With a massive raw material reserve of 500 tons of specialized materials (including Inconel 718, titanium alloys, super duplex stainless steel, and specialty carbon steels) alongside 10,000 tons of finished stainless steel standard parts, we protect our clients against global logistics delays and material supply shocks. This extensive inventory allows us to expedite custom ship bolt manufacturing and delivery times, keeping your projects on schedule.
Global procurement teams face challenges balancing regulatory compliance, metallurgical certification, and cost-efficiency. Marine installations operate under international waters and are subject to strict maritime classification guidelines. To satisfy international inspectors, marine fasteners must possess trace-verified material test reports (MTR) and meet international standards (DIN, ISO, ASTM, ASME).
Our customized solutions address these issues by providing full batch traceability, certified raw materials, and components approved by major classification societies (such as CCS, DNV, ABS, LR, and GL). Whether managing shipbuilding projects in Northern Europe, petrochemical pipelines in the Middle East, or offshore wind installations in East Asia, Beiersdorf provides verified marine fasteners with documentation that simplifies local import customs and safety approvals.
Delivering high-performance fastening solutions across demanding global industries.
Our special fasteners are widely used in the field of shipbuilding and oceanography engineering, specifically in the manufacture of special ships, marine propulsion, marine accessories, yacht manufacturing, offshore oil drilling platforms, submarine pipelines, offshore wind power, underwater lifeboats, port machinery, dock construction, etc.
These special fasteners mainly include A4-80, A5-80, D8-80, D6-70, 2205, L7, 40CrNiMoA, 718, EN14399 steel structure connection pair, classification society certificate fasteners, etc.

The maritime industry is undergoing digital transition and focusing on decarbonization. The technology roadmap for custom ship bolts is moving beyond mechanical strength toward smart connectivity and predictive maintenance. Beiersdorf is currently exploring early-stage development of smart sensor bolts. These fasteners integrate micro-strain gauges and thin-film transducers, allowing them to communicate tension, clamp load loss, and local corrosion data wirelessly to vessel monitoring systems.
Additionally, our future product development focuses on environmentally friendly coatings. Traditional cadmium plating and hexavalent chromium coatings have been replaced with zinc-flake coatings and PTFE coatings, which offer corrosion protection without environmental drawbacks. As regulations around maritime carbon footprints tighten, using highly durable custom bolts helps prevent premature component disposal, promoting a circular economy within the global shipping supply chain.
High-performance marine fasteners require precise engineering application. Standard mechanical charts often fail to account for unique torque-tension relationships under marine lubrication or wet installation settings. To prevent assembly issues, Beiersdorf provides full engineering consultation services, from material selection and torque calculation to installation procedures.
We provide engineering support that bridges regional regulatory differences, ensuring that components exported to the EU, North America, or Southeast Asia meet relevant specifications, such as ASTM, EN, ISO, and JIS. Our technical teams assist procurement engineers with the documentation required for final inspections, minimizing project sign-off delays.
