Alloy Steel Lifting Chain

Our alloy steel lifting chain is manufactured with high-strength alloy steel as the core raw material, through a full set of processes including automatic chain weaving and forming, precision fusion welding, and quenching and tempering heat treatment. It is a critical load-bearing component for industrial lifting and hoisting operations. The mainstream specification is Grade G80, with a minimum breaking strength of 800MPa and a safety factor of no less than 4 times. It features excellent tensile strength, impact toughness and wear resistance, is not prone to deformation or fracture in heavy-load and high-frequency operation environments, and can stably ensure the safety and reliability of hoisting operations. Our alloy steel lifting chain strictly complies with international production standards such as EN818-2. The weld of each chain link is precisely controlled by automated equipment in terms of fusion depth and flatness, without defects such as false welding or missing welding. The dimensions of chain links are uniformly calibrated, and can be smoothly matched with various lifting accessories such as hooks, hoists and complete riggings, fully meeting the supporting needs of different scenarios.

For different usage environments and customer needs, alloy steel lifting chain can be provided with various surface treatment solutions such as blackening, electro-galvanizing, hot-dip galvanizing and powder coating, which effectively improve the rust and corrosion resistance of the product. It can maintain stable mechanical properties for a long time even in humid outdoor areas, ports and coastal areas, and even industrial environments with mild corrosion. Compared with ordinary carbon steel lifting chains, our alloy steel lifting chain is lighter in weight under the same load-bearing grade, which is convenient for on-site construction personnel to carry and install. Meanwhile, the product has passed double verification of salt spray test and tensile test, and its actual service life can be increased by more than 30% compared with ordinary chains, which can effectively reduce customers' equipment replacement and operation and maintenance costs. It is a cost-effective choice for long-term stockpiling by overseas purchasers, engineering contractors and hardware agents.

The product is widely used in multiple core fields such as industrial manufacturing, construction and infrastructure, port logistics, and mining. In industrial manufacturing scenarios, it can be used for heavy object hoisting in factory workshops, material transfer on production lines, installation and commissioning of large equipment, and supporting lifting operations for machine tools. In construction and infrastructure scenarios, it adapts to the needs of construction material hoisting on construction sites, steel structure installation, bridge engineering construction and supporting tower crane lifting equipment. In the field of port logistics, it can meet the requirements of cargo loading and unloading at ports and docks, container strapping and fixing, and supporting use with gantry cranes and hoisting machinery. At the same time, it can also be used as the core load-bearing supporting component of equipment such as hand chain hoists, electric hoists and lifting slings, adapting to heavy-load operation scenarios such as mining, and can cover industrial lifting and hoisting supporting needs.

As an original manufacturer with more than 20 years of chain production experience, we have been focusing on the R&D and large-scale manufacturing of various industrial metal chains since our official establishment in December 2003. The factory covers an area of about 10,000 square meters, equipped with a full set of advanced production and testing equipment such as automatic chain weaving machines, automatic welding machines, positioning tensile machines, tensile testing machines and salt spray testing machines. With a stable monthly production capacity of 120 tons, we can efficiently undertake the production needs of large-volume conventional orders and customized orders. We have passed the ISO9001 quality management system certification, hold 3 invention patents, and have established an exclusive R&D team to continuously optimize product processes and performance according to market demand. At present, our products not only cover more than 30 provinces, municipalities and autonomous regions in China, but are also exported to many countries and regions in Europe, America, the Middle East and Southeast Asia, and have won long-term recognition from many overseas customers with stable quality and delivery capacity.

Our quality control for alloy steel lifting chain runs through the whole process from raw material warehousing to finished product delivery. The factory is equipped with full-time quality inspectors to conduct random inspection and patrol inspection at each production node. Each batch of products will go through multiple testing procedures such as tensile load test, dimensional accuracy calibration and appearance defect inspection. 100% full inspection is carried out before finished product packaging to ensure that each delivered product meets performance and appearance standards. We support on-site inspection by third-party authoritative institutions, and customers can entrust professional testing institutions to verify the products at any time. The product provides a conventional 6-month warranty period. If there are quality problems after receipt, exclusive after-sales personnel will connect at the first time and negotiate solutions according to the actual situation, fully protecting customers' procurement rights and interests.

We support the whole process of OEM and ODM customization services, and can carry out exclusive production completely according to the technical drawings or physical samples provided by customers. For alloy steel lifting chain, customers can customize different diameter specifications, whole roll lengths, surface treatment methods and special performance requirements. Mixed matching of different models and colors is supported within a single MOQ order. We can provide pre-production samples for customers to confirm dimensions and quality before mass production. The development cycle of customized samples is about 15 days, which can quickly respond to customers' new product development and proofing needs. Whether it is brand OEM production or exclusive specification customization, we can accurately match customers' differentiated needs and help agents build a product system with local market competitiveness.
