Rust-resistant concrete screws
Ionyx coated treatment resists rusting.
Concrete screw with ionic coated plating that has self-healing properties and has the same corrosion resistance as stainless steel.
It prevents rust caused by corrosion between different metals and metals, and is also resistant to aluminum and galvanized steel plates.
- There may be cases of discoloration and other defects in the environment of strong acid (PH2 and below) and strong alkaline (PH12 or higher) when used in the environment.Zinc base creates a unique corrosion between acid, alkali and iron and decreases corrosion resistance.
- Corrosion may occur when used with wood containing a lot of tannic acid.
- Corrosion can be accelerated in places affected by current current.
- In environments where exposed to running water, the protective film is difficult to form and reduces corrosion resistance.
- When securing the stainless steel fittings, the unique corrosion between the stainless steel and iron will decrease corrosion resistance.
