One-Coat System · 4-8 Years

Telecom Tower Anti-Corrosion Coating Process

One-CoatFast ApplicationEasy Maintenance.XGE-301 One-Coat paint combinesPrimerTopcoatinto one,1 coat achieves 4-8 year protection comparable to traditional 2-coat.For Rapid Refurbishment / Maintenance / Time-Critical scenarios. Orange/white coating provides both aviation warning and industrial aesthetics.

SubstrateHot-Dip Galvanized Steel

SystemOne-Coat (1-Coat)

ProductXGE-301

ColorOrange/White

Service Life4–8 Years

EnvironmentC2–C3 Moderate

Completion Time4–8h / Tower

1 Coat = Double Protection

XGE-301 One-Coat paint combines Primer + Topcoat into one, with 1 spray coat achieving 80% of traditional 2-coat performance.

4–8h Completion / Tower

EliminatesPrimerDrying / Intermediaterecoating steps,4–8 hours for complete tower coating, reducing project duration by 50%+.

Maintenance / Refurbishment Preferred

Single-coat application / low equipment requirements, 40% lower maintenance costs,Ideal for in-service towerRapid RefurbishmentSpot Repair.
