NXF UNS A36 S235 Carbon Steel 138-D Zinc Layer Thickness:80um Hot-dip Galvanizing Combined with Electro-galvanizing Eye Fitting

Our carbon steel galvanized eye fittings are produced through standardized, rigorous manufacturing procedures to ensure stable structure, precise dimension and excellent corrosion resistance. The whole production flow is strictly controlled in five core processes, ensuring consistent quality for mass industrial supply.

1. Raw Material Preparation: High-quality carbon steel strips and rods are selected as base materials with stable hardness and good ductility. Before production, all raw materials are inspected for surface condition, thickness and flatness. Oxidized, cracked or defective materials are eliminated strictly to guarantee foundation quality for subsequent stamping and forming processes.

2. Precision Stamping & Forming: Adopting high-speed precision stamping machines, the materials are processed into standard eye fitting shapes including eye hole forming, edge trimming and overall shaping. The whole process ensures uniform structure, accurate hole position and symmetrical appearance. Strict tolerance control effectively avoids deformation, size deviation and structural asymmetry.

3. Deburring & Surface Finishing: After stamping, semi-finished products go through professional deburring and polishing treatment to remove sharp edges, burrs and surface impurities. The smooth surface prevents scratching during assembly and ensures neat fitting, improving product safety and assembly smoothness.

4. Electro-galvanizing Treatment: Products are treated with complete electro-galvanizing procedures including degreasing, acid cleaning, surface activation, zinc plating, passivation and sealing. The compact and uniform zinc layer provides strong anti-rust and anti-corrosion performance, adapting to humid and dusty working environments and prolonging service life.

5. Full Inspection & Packaging: Finished products undergo strict inspection of dimension, appearance, zinc layer adhesion and surface flatness. Unqualified products are screened out. Qualified goods are packed with dust-proof and moisture-proof materials to ensure stable quality during long-distance transportation and bulk delivery.
