Different tones within one order
Galvanized surfaces may show different levels of brightness even within one order. Steel properties and coating formation can produce variations in colour and texture. These differences do not always indicate defects. Review appearance alongside continuity and effects on use. A photograph alone cannot establish thickness or durability.
Define architectural expectations early
For visible façades, railings or similar applications, explain acceptance expectations at quotation stage. If a sample is used, define which characteristic it represents. Colour consistency, tactile finish and visible assembly surfaces are separate concerns. Painting after galvanizing requires separate consideration of preparation and the coating system.
Acceptance assessment
Mark observations such as roughness, build-up or uncoated areas on the component and discuss them with the technical team. Features affecting safe use, assembly or function need specific review. Determine any corrective work against project requirements. Marking visible surfaces on drawings helps Galmetsan consider aesthetic expectations alongside technical coating needs.
Requesting a technical review using photographs
A very close photograph alone can make a surface observation difficult to locate. Provide an overall view, a close-up and component identification together. Explain whether the area remains visible after assembly, is touched during use or affects any function. Lighting and camera angle can alter apparent colour differences. Photographs assist preliminary review but do not always replace measurement or direct inspection. Technical assessment then establishes acceptance or corrective scope.
