Common Coating Failures in Steel Structure Projects and How to Avoid Them

Steel structure coating failure is rarely a pure product-quality issue; it’s usually a mismatch between surface condition, environment severity, and the coating system design and controls used during application. The fastest way to prevent repeat failures is to treat each symptom (peeling, blistering, underfilm corrosion, early rust) as an inspection problem: verify surface cleanliness (including […]

Anti-Corrosion Coating for Steel Structures: System Selection Guide for Industrial Projects

Industrial steel structure corrosion failures are usually caused by system selection errors—the environment is underestimated, the film build is under-designed, or the execution plan (surface prep + QC) cannot achieve the assumed performance. ISO 12944 helps engineers avoid this by requiring two inputs first: corrosivity category (C2–C5/CX) and durability class (L/M/H/VH, defined as time to first […]

Fireproof Coating System for Steel Structures: Types, Standards & System Design

A fireproof coating system for steel structures is not a single “fireproof paint”—it is a tested and specified system (typically primer + passive fire protection layer + optional topcoat/sealer) that must match the required fire scenario and be applied exactly as required to keep the rating. UL explicitly warns that deviations from certification requirements and individual design […]
