Coil chains are industry-standard chains used in the industrial hardware category for several applications, including machine safety, overhead lifting, and industrial hardware. They are made of hardened steel links that are welded together to form a continuous chain. The links forming the chains are made of either low carbon or high carbon steels. Coil chains come in different sizes, grades, and finishes. Choosing the right coil chain is important when deploying them in any application.
Coil Chain Sizes
The size of the coil chain to choose depends on the task it is going to perform. For instance, if the chain is going to lift heavy loads, it requires one with large diameter links that can support and withstand the weight. Here are the different sizes of coil chains:1. 1/4-inch chain:
This is the smallest chain in diameter; it is the most flexible, making it suitable for decorations, suspensions and light load applications, such as garden swings. It’s rated for lower weight capacity, generally not above 500 lbs.2. 3/8 inch chain:
This chain is thicker and stronger than the 1/4-inch chain, making it suitable for heavier loads, such as machine safety, signage, and anchoring of equipment. It has a weight capacity of between 500 lbs to 2,650 lbs.3. 1/2 inch chain:
This is the largest standard diameter of coil chain; it’s the heaviest, most robust, and has the highest weight capacity of up to 4,500 lbs. It’s commonly used in outdoor applications such as ships’ anchors, trailers, and overhead cranes.Coil Chain Grades
Coil chains come in different grades, which refer to their tensile strength. Tensile strength is the maximum stress or load a chain can withstand before it breaks, expressed as pounds per square inch (psi). Here are the different grades of coil chains:1. Grade 30:
Grade 30 coil chains are made of low-carbon steel; they have a tensile strength of 30,000 psi and are suitable for light-duty applications, such as hanging small machines and overhead doors.2. Grade 40:
Grade 40 chains are made of quenched and tempered steel, giving them higher tensile strength than grade 30. They have a tensile strength of 40,000 psi, making them suitable for a wide range of rigging applications such as overhead lifting, securing large equipment and machinery.3. Grade 70:
Grade 70 coil chains are used for heavy-duty applications requiring high tensile strength. They’re manufactured from heat-treated carbon steel, making them exceptionally strong, with a tensile strength of 70,000 psi. Grade 70 chains are commonly used in the transportation industry for securing cargo.Coil Chain Finishes
Coil chains come in three finishes, each with its advantages.1. Black oxide finish:
This coating increased rust and corrosion resistance, making it ideal for outdoor applications. However, it gradually wears out due to frictional forces, leaving the chain exposed.2. Zinc-plated finish:
The zinc-plated finish protects the chains from rust and corrosion by reducing the rate of oxidation. Chains with this coating can safely be used outdoors when exposed to moderate moisture. However, the plating can chip off, leaving the chain unprotected.3. Galvanized finish:
Galvanizing is a process of dipping the chain into molten zinc to form a protective coating. It is corrosion resistant and has been rated to last longer than other coatings, making it ideal for outdoor use, including marine applications.Considerations When Choosing Coil Chains
Here are some factors to consider when choosing coil chains:1. Application requirements:
Understand the application needs of the task the chains are intended for. Factors such as weight capacity, environmental exposure, and load-bearing requirements are essential.2. Breaking strength:
It is critical to know the chain’s breaking strength, which is the maximum amount of weight the chain can withstand before it snaps. This information can be found on the manufacturer's label.3. Chain material:
The type of material the chain is made of highly influences the chain’s strength, flexibility, and durability. Choose the right material based on the requirements of the application.4. Chain size:
Choose the right size of chain, considering the weight capacity, load-bearing requirements, and environmental conditions.5. Chain grade:
Understand the application requirements and select the suitable coil chain grade based on the application range.6. Chain finish:
The chain’s coating determines its ability to resist rust and corossion. It is essential to choose a finish that is resistant to the environment in which the chain will be used.Conclusion
Coil chains are common in the industrial hardware category and are used in various applications requiring rigging, overhead lifting, and suspension. When choosing coil chains, it’s essential to consider factors such as the application requirements, chain breaking strength, material, size, grade, and finish. This guide provides essential tips when selecting coil chains, ensuring you make the right choice for the intended application.Related Topics You Might Like
