High-speed railroad, subway, light rail
High-speed railway, subway, light high-speed railway design life
long, embedded parts require more bridges, high corrosion
resistance, subways, and tunnels are in the ground, dark
environment ,poor ventilation and humid, rail, screws, bolts,
catenary embedded parts, and other vulnerable rusty. To achieve
maintenance-free, high anti-rust requirements are high-speed
railway, subway, light rail bridge embedded parts, catenary
embedded parts, road screw bolts etc. should be subject to a
multi-alloy permeation layer closed + skills Dacromet reports.
