1 Inch 25mm*800kg/1760lbs ratchet tie down buckle is mainly made of which metal material? What is the maximum tensile strength? How is the corrosion resistance under long-term use and harsh environments?

Material
1 Inch 25mm*800kg/1760lbs ratchet tie down buckle is mainly made of steel material. Steel is a strong and durable metal material that is widely used in various mechanical components and structural parts because of its high strength, good plasticity and toughness.

Maximum tensile strength
The breaking strength of this ratchet strap buckle is 800kg/1760lbs, which can also be considered as its maximum tensile strength. This means that under normal use conditions, the ratchet buckle can withstand a maximum pulling force of 800 kilograms or 1760 pounds without breaking. This strength is sufficient for cargo lashing and harness applications.

Corrosion resistance
Steel itself has certain corrosion resistance, but the specific corrosion resistance depends on factors such as the alloy composition, heat treatment and surface treatment of the steel. The surface of the ratchet buckle is black zinc plated. The galvanized layer can significantly improve the corrosion resistance of steel parts, especially in harsh environments such as moisture and salt spray. The black zinc coating not only provides an attractive appearance but also provides additional protection against corrosion. In long-term use and harsh environments, the corrosion resistance of the ratchet buckle will be challenged. However, thanks to the steel material and black zinc finish, its corrosion resistance should be sufficient for applications. However, in order to ensure the long-term performance of the ratchet buckle, it is recommended to perform regular maintenance and inspections and promptly replace damaged or severely corroded parts.
