Hot-dip galvanized bolts, known for their high strength and corrosion resistance, are widely used in power transmission towers, highway guardrails, signal towers, lighting towers, and other critical structures. However, during installation, the fastening torque may locally damage the zinc coating on the bolt surface. If not repaired in time, the bolts can rust or even corrode severely, compromising the stability of the entire structure.

With Mengneng Coating applied after bolt installation, the corrosion resistance can be significantly enhanced, effectively preventing premature rusting. The application process is extremely simple: open the can, stir, and brush—just three steps. Additionally, aerosol products are available, allowing quick on-site spraying for effortless repair of damaged areas. Thanks to its high zinc content, Mengneng Coating offers rust protection comparable to hot-dip galvanization. A single repair ensures long-term corrosion resistance.

With Mengneng Coating, the corrosion issue of hot-dip galvanized bolts is completely solved.
