G70 chains, also known as tow chains or transport chains, have become the preferred solution in areas such as lifting, transportation, and towing due to their excellent strength and durability.
High Strength
G70 chains are made of high-strength carbon steel and undergo heat treatment, resulting in a structural strength far surpassing that of G43 chains, enabling them to withstand heavier loads.
Corrosion Resistance
The heat treatment of G70 chains not only enhances their strength but also increases their corrosion resistance. Additionally, the zinc plating on the surface of the chains significantly enhances their corrosion resistance, preventing oxidation corrosion.
High Visibility
The surface of G70 chains is typically treated with zinc yellow chromate, not only improving corrosion resistance but also making them easily distinguishable from other chains due to their prominent color.
For different load, corrosion-resistance, or transport requirements, we also supply Heavy Duty Chain Manufacturer and Tow Chain.
Excellent Working Load Capacity
TuoHai’s G70 chains are crafted from high-strength alloy steel and undergo heat treatment.
Combined with TuoHai’s advanced production processes, our G70 transport chains exhibit extremely high working load capacities, surpassing G43 chains by over 25%. Their performance exceeds industry averages, enabling them to withstand greater pulling forces without fracturing.
Customizable to Various Standards
TuoHai’s G70 transport chain production line is independently developed, allowing for flexible adjustments according to customer requirements and standards.
We can provide G70 chains in various standards such as ASTM, NACM, ASME, EN, and ISO, ensuring higher applicability and safety during usage.
100% Test Pass
Before leaving the factory, our G70 chains undergo rigorous testing and calibration, including tension tests, load tests, salt spray tests, and surface treatment inspections. This ensures that all G70 chains have straight shapes, stable structures, and performance far surpassing various international standards, which is particularly crucial when bearing heavy loads.
