TOPONE® produces Flat link Chains for use in continuous conveyors in mining Complies with DIN22255 dimensions and mechanical properties. Flat link mining Chains may replace currently used round link Chains of the same diameter, without the need of changing other assembly components.Especially suitable for Armored Face Conveyors, Beam Stage Loaders, road headers.

TOPONE® uses DIN 22252 standard to produce round steel Chain links for continuous conveyors and excavation equipment in the mining industry. The steel used to produce the welded round link Chain contains alloy elements such as Cr Ni Mo. It can meet Grade D (1050MPa), Grade C++ (900MPa), and Grade C (800MPa).Suitable for Armored Face Conveyors (AFC), Beam Stage Loaders (BSL), road header machines, coal plows and other equipment that requires this type of Chain.

TOPONE® Grade 80 Chain uses low-carbon alloy steel containing Cr, Ni, Mo, and Al. It is quenched at a temperature above AC3 and tempered at a temperature above 400 degrees Celsius. This makes the Chain strong, tough, and fatigue-resistant. It is suitable for any cargo lifting or transportation lashing scenarios. All Chains are tested for a tensile force of 2.5 times the working load before leaving the factory.The Chain is stamped with "G8" grade and batch number identification.

Widely used in marine, chemical industry, food processing and some extreme environments.

Material: AISI 304, AISI 316, AISI 316L

Proof load design factor 4:1

Warning: Do not exceed the working load limit!

Not suitable for overhead lifting!

Short, wide link Chain which resists kinking or tangling, made of carbon steel. Not to be used in overhead lifting.

Long pitch straight link, general utility Chain made of carbon steel.

Not to be used in overhead lifting.

Not to be used in overhead lifting.

Whether it is a farm, industrial scene or handmade DIY, this Grade 30 Proof Coil Chain produced by TOPONE® can meet the needs. We can provide regular sizes and long ring links. The Chain is made of carbon steel and is resistance welded. Various surface treatments can be selected.

Grade 43 High Test Chain is also called G4 or G40 Chain, which is a heat-treated alloy steel Chain. Its performance is lower than G70 Chain but higher than G30 Proof Coil Chain., construction, agricultural and lumbering operations.​Not to be used in overhead lifting.Flash welding is adopted, and the weld surface is smooth, flat and free of burrs.Various surface treatments such as hot-dip galvanizing and electro-galvanizing are available.Proof tested to 2x the Working Load Limit.
