Technical chains

Technical chains are the products of choice when it is necessary to connect components in a mobile manner and, at the same time, to meet stringent strength requirements. The strength of technical chains is determined by both the size of the links and the way in which they are connected. Welded technical chains can lift many tonnes and their breaking strength reaches values of more than 100 kN. As standard, they are used in lifting and moving techniques for heavy loads. Due to their varied parameters and possible manufacture in specific materials, such as hot-dip galvanised wire, they can be used in garages as well as in manufacturing companies or on construction sites. Technical chains are the chain of choice for drive assemblies and slings. They also perform well in mechanical equipment.
At Mostostal-Met, we manufacture chains in electro-galvanised or hot-dip galvanised versions, as well as bare wire chains.

Hot-dip galvanised chains

Hot-dipgalvanised steel chains gain the characteristics of a durable product. Hot-dip galvanised steel, i.e. by immersion in a liquid hot zinc-iron alloy, is significantly more resistant to the ageing process. The corrosion protection period for chain links made from it, but also for the stainless steel technical nets manufactured in our plant, is approximately 50 years. Hot-dip galvanisation also results in better cathodic protection, as it inhibits the oxidation process of the steel. More importantly, the product's friction and impact resistance parameters are also improved, which is of paramount importance in the case of technical chains used for load handling, as it determines their quality. The advantages of hot-dip galvanisation also include its cost-effectiveness and lack of environmental impact.

Electrolytically galvanised (electroplated) chains

Electrolytic zinc plating is a mechanised, multi-stage process that involves degreasing the steel, removing traces of corrosion from it and immersing it in a zinc-saturated electrolyte solution. The resulting zinc coating is perfectly smooth and uniform, so that it can be evenly coated with paint in the next production stage. It is thinner than the coating produced by the hot-dip galvanising method, yet still effectively protects the product from rust.
