    The surface-Dacromet:

    Super corrosion resistance. It has more advantages than the traditional electroplating process.
    High heat / high temperature corrosion resistance, the temperature can reach more than 300℃
    Good bonding force for better anti-attrition performance.
    Good permeability.
    No pollution and public hazards, reduce the cost of treatment.

    The surface – Ruspert:

    Ruspert is a new metal surface treatment technology with high corrosion resistance, high temperature resistance, no hydrogen embrittlement, no pollution, acid and alkali surface hardness and other characteristics, corrosion resistance is 5-10 times of galvanizing (salt spray test can reach more than 1000 hours, the product meets the European environmental protection report ROHS standard, color black, silver white, silver gray, gold and other options) heat resistance of more than 240℃.
    Can replace dacroxol, chromless dacroxol, electric galvanizing, hot galvanizing, mechanical galvanizing, electrophoresis, trichromium black zinc and other traditional processes.
    Application: Used in communication, electric power, machinery, automobile, railway, tunnel, highway guardrail, chemical industry, Marine engineering, electrical automation, household appliances, office furniture, computer and other fields.
