Haberdashery rings and D rings are undoubtedly one of the most frequently used fittings. You can choose from a variety of materials and designs. In this article you will learn which one, what is the difference between them and what they suit the best.
Non-welded from steel
The fittings is made by twisting thin steel wire with a very thin surfacing – nickel, chromium and covering with zinc. fittings endings are spaced 2-5 mm, not connected by welding. The rough edges are very sharp and you can see the damage after a parting tool on them. The solidity of these D rings and rings is very small. When used sharp non-welded edgesmay damage the product and be easy to deform when under a tensile load. Using haberdashery fittings with non-welded edges from thin wire excessively devalues the product quality. The quality of haberdashery fittings shows the product quality and expertise of the manufacturer.
Welded from steel with nickel or chrome surfacing
Haberdashery fittings is mostly used. The fittings is made by twisting stronger steel wire, connected by welding and subsequently finished by a stronger layer – nickel and chromium. Nickel is asilvery white, very shiny, tensile metal. It has less resistance to acids, alkalis and water. Fittings with this surfacing is not suitable for products that are longer in contact with water and chemicals. Nickel forms only a protective layer for the fittings and its surface cannot withstand higher mechanical loads. The fittings is not suitable for products where there is the greater and permanent mutual and tensile friction of two nickel surfaces. Chromium is a pale white, shiny, very hard metal. A thin layer of chromium not only protects the surface of the haberdashery fittings from corrosion but also increases its hardness. It has similar chemical and physical properties to nickel.
The welded fittings has a regular greater tensile strength than the non-welded one. In products using welded fittings no deformation of the D rings occurs in tension as well as no damage of the product materials from non-welded edges of the D rings.
Use: for haberdashery fittings with smaller loads for tension, sports bags and backpacks, which are expected for occasional exposure to adverse weather conditions. Collars and harnesses for smaller dog breeds (poodle, Yorkshire Terrier, Dachshund…). Handbags, bags, briefcases, cases and other small haberdashery fittings.
Cast from zinc
Zinc is a shiny blue-white metallic element. It is very malleable and has good leaking properties. Haberdashery fittings produced from zinc is cast in molds and by subsequent nickel surfacing.
Use: Haberdashery fittings cast from zinc is suitable for goods where you need subtle fittings with less tension in load. Sports bags, collars and harnesses for smaller dog breeds (poodle, Yorkshire Terrier, Dachshund…). Handbags, bags, briefcases, cases and other small haberdashery fittings.
Made from brass
Brass is an alloy of copper and tin, with the addition of other metals (e.g. aluminum, manganese, lead). The ratio of these metals gives brass its unique properties. It has high resistance to corrosion, acids, alkalis and high temperatures. Haberdashery fittings is made by casting the brass.
Use: brass haberdashery fittings is suitable for haberdashery products where there are expected higher loads in weather conditions, acids and bases. The fittings is suitable for covering diving equipment, sailing and fishing gear (brass not depreciated with longer exposure to salt water). Harnesses and leashes for medium dog breeds (beagle, cocker spaniel, Irish setter, rough collie …).
Made from stainless steel
Most recently haberdashery fittings has been produced from stainless steel (high-alloy steel). It contains a large proportion of chromium, nickel, manganese and other metals causing its resistance to corrosion. Stainless steel has increased resistance to chemical and electrochemical corrosion. Corrosion resistance is based on the ability of the so-called subjecting of iron surfaces. Stainless steel has very good mechanical properties – solidity in tensile and pressure.
Use: the qualities of haberdashery fittings with stainless steel predetermine its use on very and extremely strained products. Diving, sailing and fishing equipment. Harnesses and leashes for large dogs, ponies and mushing.
