DIKA SIGN fabricates stainless steel letters classified primarily by surface finish. Brushed stainless steel letters creates a controlled directional texture; mirror-polished letters deliver high reflectivity; PVD-coated letters add durable metallic colors such as gold, bronze or black; painted stainless steel provides precise brand-color matching. Each finish can be applied to flat-cut, solid or fabricated hollow letters, with illuminated or non-illuminated construction selected according to the project. Grades such as 304 or 316 stainless steel can be specified for interior, exterior, coastal or higher-corrosion environments. Important parameters include letter size, face and return thickness, depth, weld finishing, grain direction, mirror quality, PVD color, paint system, illumination, backing and mounting. Supported by Shanghai-based project coordination and factory-direct manufacturing in Lu’an, DIKA SIGN provides finish samples, shop drawings, welding, polishing, brushing, PVD coordination, painting, lighting tests and export packaging. This controlled workflow gives sign partners consistent finishes, clean detailing and dependable installation across one-off or multi-location programs.
