How to distinguish finished zipper from zipper chain?

Different types of zippers are used to manufacture various commodities. Although various materials are used in the production, such as plastics, metals, coils, etc., the main purpose of the zipper to secure objects is still the same. However, the application of the zipper must be kept in mind before buying. Through this article, we will discuss the difference between finished zippers and chain zippers and their suitable applications.

The main difference between finished zipper and zipper chain

The main difference between them is the length. The finished zipper has a specific length and various components are installed. Zipper chains are usually very long, with continuous loops, without conventional zipper heads and stops. They can be customized to various lengths according to your needs.

When ready-made or customized length zippers are needed, finished zippers are the best choice. But zipper chains are sold according to the size. They are more suitable for items that require long zippers, such as home textiles, such as pillows, upholstery, cushions, etc., or clothing that requires various zipper lengths. You have to be very careful with zipper chains because plastic, metal and coil zippers are different from each other. The sliders prepared for metal zippers cannot be applied to plastic or rolled zippers, and vice versa, which may cause zipper failure.
