Introduction: Comprehensive Protection for Tunnel Boring Investments

A Tunnel Boring Machine represents a multi-million dollar investment that must perform reliably for years underground. Piece-meal coating approaches leave vulnerable areas exposed, leading to progressive deterioration and premature equipment retirement. FLD’s anti-corrosion coating system for TBM entire machine provides a unified protection strategy that covers all components with matched, compatible coatings.

Core Benefits

Complete Machine Protection

Our system covers every TBM component—from cutterhead to tail shield—with coatings formulated for each area’s specific exposure conditions.

Compatible Coating Layers

All coatings in our system are chemically compatible, eliminating inter-coating failures at component interfaces.

Service Life Matching

Coating durability is specified to match the TBM’s design service life, avoiding mid-project coating failures.

Reduced Maintenance Burden

Unified coating system simplifies maintenance, with consistent touch-up procedures across all components.

Key Features
