What materials are the metal parts on the 1″ x 15″ Ratchet Tie-Down Set (4-Pack) made of, and what special treatments are applied?

1. Materials of Metal Parts
Most of the metal parts on the 1″ x 15″ Ratchet Tie-Down Set (4-Pack) are made of steel. Steel has high strength and toughness, and can withstand large tension and pressure, making it very suitable for making metal parts of tie-downs that need to withstand heavy objects.
2. Special treatments of metal parts
PE rubber coating:
PE (polyethylene) rubber coating is a common metal surface treatment method. By coating a layer of PE rubber on the surface of metal parts, its wear resistance, corrosion resistance and anti-slip properties can be improved. PE rubber coating has good elasticity and flexibility, and can adapt to the slight deformation of metal parts during use, thereby extending its service life. The coating can also provide a certain buffering effect, reduce friction and collision between metal parts and goods or other surfaces, and reduce the risk of damage.
Galvanizing:
Galvanizing is to immerse metal parts in molten zinc liquid to form a layer of zinc coating on their surface. This treatment can significantly improve the corrosion resistance and rust resistance of metal parts. The zinc coating has good adhesion and hardness, and can protect metal parts from environmental factors such as moisture, salt spray, etc. The galvanizing treatment can also increase the beauty of metal parts, giving them a silvery-white metallic luster.
Plastic spraying:
Plastic spraying is to attach plastic powder to the surface of metal parts by electrostatic spraying, and then form a hard coating after high temperature curing. The plastic spray coating has good weather resistance, corrosion resistance and wear resistance, and can protect metal parts from oxidation, corrosion and wear. Plastic spraying can also provide a variety of color and texture options to meet the needs and aesthetic requirements of different customers.
3. The role of special treatment
Improve durability: Through special treatments such as PE rubber coating, galvanizing and plastic spraying, the wear resistance, corrosion resistance and rust resistance of metal parts can be enhanced, thereby extending their service life.
Increase safety: Special treatment can reduce friction and collision of metal parts during use, reduce the risk of damage, and at the same time improve the overall strength and stability of the strap to ensure the safe fixation of goods.
Improve aesthetics: Treatments such as galvanizing and plastic spraying can provide metal parts with a variety of colors and textures, making them more beautiful and in line with modern aesthetic requirements.
