For different load, corrosion-resistance, or transport requirements, we also supply Coated Steel Chain and Heavy Duty Chain Manufacturer.
Excellent Working Load
Tuohai’s production equipment and various molds are continuously adjusted and designed on-site by experienced engineers. As a result, our straight link chains have an excellent link shape and can withstand working loads far exceeding standard requirements, ensuring greater safety during use.
Advantage of Tuohai
Tuohai possesses several advanced production equipment and technologies, including high-precision CNC forming, automated welding, efficient heat treatment, and computer-aided design and manufacturing. These technologies ensure the high strength, durability, and excellent safety of our straight link chains. Additionally, our production line is fully automated, enabling continuous production, reducing human intervention, and improving production efficiency.
Tuohai is equipped with advanced welding technologies and equipment, offering resistance welding, argon arc welding, and laser welding. Testing has shown that the strength of the welded joints surpasses that of the base material, and the welds are smooth and even. In break tests, the welded joints of our straight link chains remain intact even when the chain itself breaks. This verifies the reliability and stability of our welding quality, ensuring the safe use of our products for lifting, hauling, or binding purposes.
Why Choose Tuohai
To ensure product quality, Tuohai requires material reports, carbon content, and other inspection reports for each batch of raw materials procured. During the production process, we conduct random inspections, and once production is complete, the products undergo even more stringent testing, including salt spray tests, tensile tests, and surface treatment inspections. This ensures that our products meet and exceed various standards.
To ensure customers receive the products they need promptly, Tuohai keeps a stock of standard or commonly sized straight link chains, with the lowest MOQ. These chains require only simple surface treatment before shipment, saving you valuable time.
Surface Treatment of Straight Link Chain in Tuohai
Hot-dip galvanizing creates a thick zinc protective layer on the surface of the chain, significantly enhancing the service life, rust resistance, corrosion resistance, and wear resistance of the straight link chain. This allows even carbon steel chains can be used long-term in corrosive environments. Additionally, the zinc layer has self-healing properties, even if the surface is damaged, the hot-dipped galvanized chain can protect the internal chain through electrochemical reactions.
Electro-galvanizing is one of the most common surface treatment methods, forming a dense zinc layer on the chain surface through electroplate. Although the zinc layer of electro-galvanizing is thinner and thus not as rust-resistant as hot-dip galvanizing, it is still suitable for most environments outside extreme conditions. Moreover, the surface of the zinc-plated chain is smoother and more aesthetically pleasing than hot-dipped galvanizing, making it suitable for a wider range of applications.
Depending on different usage requirements, Tuohai offers various surface treatment options such as powder coating, plastic coating, and PVC coating. These treatments not only effectively improve the rust and corrosion resistance of the chain but also provide various color options, enhancing the chain’s visibility. Examples include yellow-coated chain, white-coated chain, and black-coated chain. Additionally, coated chains offer insulation properties, making them safer for use in electrical equipment applications.
This surface treatment is suitable for stainless steel straight link chains or brass straight link chains. These materials inherently possess excellent rust and corrosion resistance, allowing them to be used directly without additional treatments.
This treatment is typically used for short-link, high-strength carbon steel chains or alloy steel straight link chains, such as G70 transport chains and G80 lifting chains. These chains require high strength, and heat treatment is an effective method to increase hardness. Chains used for high-altitude lifting, heavy-duty dragging, safety chains, and anchor chains often undergo heat treatment to achieve the necessary strength.
More Informations About Tuohai Straight Link Chain
- Applications of Straight Link Chain
Lifting and Towing
Heavy-duty straight link chains of G80 grade and higher are suitable for lifting applications due to their high strength and durability. They are used for lifting or moving heavy objects, typically selecting short-link chains for high-altitude lifting. In the towing of trailers and boats, appropriately standard straight link chains can be used to safely connect and secure.
Transportation and Handling
G70 grade straight link chains are commonly used in the logistics industry to bind or secure cargo during transportation. Straight link chains are also widely used in industrial or agricultural equipment, such as conveyor systems and agricultural machinery.
Security and Protection
Hardened straight link chains are often used to make lock chains and security chains. These chains have extremely high hardness and cannot be cut, making them suitable for locking vehicles, bicycles, and doors or windows. On farms, construction sites, or in hazardous areas, straight link chains can also be used for fencing.
Marine and Maritime Applications
Hot-dipped galvanized straight link chains can be used as anchor chains, mooring chains, and in various marine equipment applications.
Everyday Applications
In daily life, coated or electro-galvanized straight link chains are used for garden and outdoor decorations, such as hanging flower pots or lamps. They can also be used as swing chains, typically selecting lighter, long-link chains for flexibility. Additionally, plastic-coated short-link straight link chains can be used as elevator balance chains.
