Steel rope consists of a number of strands of steel wire torsioned spirally. Steel wire ropes are manufactured in accordance with EN 12385-4 standard. They have a wide range of application - energy, mining, chemical industry, metallurgy, machinery, port- activity, electrical and railway transport, construction and others. Steel ropes are the fundamental structural element for many machines and installations. They are used in elevators, cranes, building sky tracks, bridges, highways and other metallic constructions.

Kastel Karlovo JSC is a distributor of Saint-Gobain abrasives, France

Saint-Gobain Abrasives is the world's leading manufacturer of abrasives, it is the only international supplier that produces all three main types of abrasives - abrasives for grinding (with organic and ceramic joints), sand paper and diamond products.

As a distributor of Saint-Gobain for the territory of Bulgaria, Kastel Karlovo JSC offers Norton & Winter brand products.

Abrasives are used for surface treatment of different materials, by removing thin shavings, using technology that allows high-precision in achieving required dimensions and surface.

Chain slings are manufactured according to EN 818-2, safety class 4: 1. Their main advantage is the ability to shorten each shoulder by means of shortening hooks placed next to the main ring of the sling and thus are a preferred means of lifting loads of irregular shape. Chain slings can be made with up to 4 arms and a different element can be placed at each end of the sling - a ring, hook, shackle or other specialized grip.

Class 10 chain slings are made in accordance to the requirements of the world quality standards EN 818-4-2017. Class 10 chains, as well as the individual elements (hooks, rings, etc.) are blue. Class 10 chain slings have an increased load capacity by 25% (69 tons) compared to class 8 chain slings (55 tons) and they allow direct mounting of the elements without the use of additional connectors such as connecting links or shackles.

Steel wire rope slings are manufactured according to EN 13414-1 and are made of steel wire ropes with different construction - 6x19, 6x36, 6x37 with organic or metal core. They are made of both galvanized and non-galvanized ropes. Steel rope slings can have up to four separate arms.

Kastel Karlovo JSC manufactures crimped or woven eye slings up to diam 76mm with a load capacity of 70 tons. Per customer's request an additional element such as hook, link, shackle or another element can be placed at each arm of the sling.

Round polyester slings are made of high quality polyester fibers wrapped in a protective cover. When using round slings, there is the lowest risk of injury to the load. Their main advantage is their flexibility, lightness and significantly smaller bandwidth compared to flat-eye slings. They also have a higher load capacity - up to 150 tons.

Polyester webbing slings are one of the most common products for lifting loads and are used in all industries due to their high load capacity. They are characterized by lightness, flexibility and long service life.

Different types of accessories such as links, hooks, shackles and other specialized grips can be attached to the arms of the polyester webbing slings. There are two types of polyester slings - eyeless, round polyester slings (load capacity up to 100 tons) and flat-eye polyester slings (load capacity up to 30 tons). They have a security ratio of 7: 1.

Webbing slings are resistant to aggressive environments and liquids, the operating temperature at which they can be used is from -40 to +100 degrees. The slings are color coded and are manufactured according to EN 1492-1. Each sling has a sewn certificate showing its length, workload, serial number and date of manufacture and is accompanied by a quality certificate, declaration of conformity and instructions for safe use.
