Grade 43 High Test chain also known as G4 or G40 chain conforms to ASTM A413/A413M standards. Suitable for industrial, construction, agricultural and logging operations. These chains are not designed and produced for overhead lifting purposes. They are tested to 2 times the working load before leaving the factory.

TOPONE® can produce 100% ASTM A413 G70 chain, with regular sizes and Short Link options available.A high quality, high strength carbon steel chain, heat treated,Used for load securement.Not to be used in overhead lifting.Meets Department Of Transportation Regulations.The surface is yellow chromate color.TOPONE® Grade 70 chain is the chain of choice for load binding applications. It is also well suited for tie-downs, towing and logging operations. Its strength to weight ratio exceeds that of Proof Coil and High Test chain.

Grade 80 chain used in overhead lifting applications. 80 chain has excellent energy absorption and is manufactured using special analysis alloy steel. G80 alloy chain is rugged, versatile, high-strength, low-weight chain. Quenched and tempered before proof testing, Grade 80 chain specs & dimensions have tensile strength twice of ordinary steel chain.

Made of special CRNIMO alloy steel, 25~30% stronger than grade 80 chain. The weight for Grade 100 chain is on average 20% lighter than Grade 80 chain at the same working load. Meets the chain performance requirements of ASTM A973

TOPONE® high wear-resistant round link chains are available in a variety of hardness. They are particularly suitable for scraper conveyors and high-hardness geology or materials. The surface hardness can reach up to 64HRC. Carburizing treatment is available.

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.
