A single number of years is not enough
The protective life of galvanizing varies with exposure. The same product should not be expected to behave identically in a dry environment and one with persistent moisture or pollutants. A single lifespan figure is therefore inappropriate for all galvanized steel. Any estimate should state its exposure assumptions, coating characteristics and assessment method.
The influence of design and execution
Water-retaining details, inaccessible connections and post-coating damage can change local conditions. Thickness is an important input but does not describe the entire service scenario. Storage, transport and installation also affect the coating’s initial condition. Addressing these details during design creates a more complete protection plan than specifying thickness alone.
How should a project be assessed?
Share the location, exposure mechanisms, intended service period and maintenance access with the technical team. Update the assessment when assumptions change. Observation and maintenance records help track actual conditions during use. When seeking information from Galmetsan, discuss project exposure and acceptance expectations rather than relying on general lifespan claims.
Service life and warranty are different
Estimated service life is a technical assessment based on assumptions. A warranty is a commercial commitment with separately defined scope and conditions. Do not interpret a number of years in a general guide or table as an order warranty. Ask whether an estimate concerns first maintenance, a particular corrosion level or another limit. Project exposure and maintenance assumptions should match that definition. Addressing service-life expectations separately from contractual commitments reduces ambiguity.
