DIKA SIGN develops aluminium light box signs primarily around extruded aluminum profile systems, giving sign companies a more modular, consistent and serviceable alternative to fully welded cabinets. Precision profiles support stable frames, controlled face retention, integrated drainage and weather sealing, accessible LED modules and faster replacement of graphics or display faces. This improves fabrication efficiency, reduces maintenance time and provides better cost control for repeatable indoor and outdoor projects. Single-sided or double-sided configurations can be wall-mounted, hanging, projecting or freestanding. Fully welded custom aluminum cabinets remain available for oversized dimensions, unusual shapes or project-specific depths. Key specifications include overall size, profile depth, face material, graphic method, LED layout, brightness, color temperature, power supply, ventilation, drainage, service access and mounting. With Shanghai-based project coordination and factory-direct manufacturing in Lu’an, DIKA SIGN provides shop drawings, profile fabrication, electrical assembly, illumination testing, pre-assembly and export-ready packaging for installation-ready aluminum light box.
