Galvanized Metal Flat Washers

Galvanized Metal Flat Washers are essential flat fastening accessories made of carbon steel base material, produced by precision stamping molding technology. The hot-dip galvanizing or electro-galvanizing surface treatment effectively isolates air and moisture, greatly improving the rust and corrosion resistance of the flat gasket itself. The thickness tolerance of Galvanized Metal Flat Washers is controlled within ±0.03mm, the inner and outer circle dimensional accuracy meets international general industrial assembly standards, and the flatness of the surface is strictly inspected to avoid deformation during bolt locking. Ningbo Gangtong Zheli Fastener Co., Ltd. adopts full-automatic stamping production lines with a daily output of over 12 tons of flat washers, and each batch of raw steel materials comes from domestic well-known steel mills with complete material test reports.

Application Scope & Matching Advantage

Mechanical manufacturing, new energy photovoltaic support, building steel structure, automobile chassis assembly, pipeline fixing and other industries all need stable pressure-bearing gaskets, and Galvanized Metal Flat Washers can evenly disperse the locking pressure of bolts to prevent the contact surface from being scratched and loose during long-term equipment operation. The product supports conventional size spot supply and non-standard size customized processing, with more than 160 common specifications in stock at all times. All finished products pass salt spray test detection, the electro-galvanized flat washers can reach 48 hours neutral salt spray without red rust, and hot-dip galvanized flat washers can reach more than 500 hours salt spray resistance. Ningbo Gangtong Zheli Fastener Co., Ltd. has cooperated with more than 80 overseas hardware distributors for stable bulk supply all year round, and the product inspection report can be provided to customers free of charge.

Production Quality Control

All manufacturing procedures of Galvanized Metal Flat Washers are equipped with dedicated inspectors for random sampling. Complete test records are archived for every procedure including raw material incoming inspection, precision stamping forming, galvanizing surface finishing and finished product sorting. Professional testing equipment is deployed on each production station to measure hardness, flatness and dimensional precision of flat washers. This type of flat washer maintains steady global market demand, and standardized manufacturing flow guarantees uniform mechanical performance across all batches, fully satisfying long-term high-strength assembly demands from industrial clients around the world.
