Production, Installation, And Service
Signs are made using laser cutting and CNC engraving. 3D numbers are glued onto the plate, and the surface is finished with electrostatic spraying or brushed polishing. The reflective letters are high-brightness, and the signs meet IP54 protection standards. They are suitable for temperatures from -30°C to +60°C. The reflective coefficient is at least 200 cd·lx⁻¹·m⁻².
For installation, signs are mounted on exterior walls using expansion screws. Recommended height is 3–5 meters above ground, typically above the first floor, with no obstructions. Numbers and letters are uniform in size, with high-contrast colors, such as black on silver or white on black, ensuring clear visibility.
We carefully handle signs to prevent damage and take photos before packing. If any damage occurs during transit, customers can provide photos, and we will send free replacements.
We offer a 1-year warranty and lifetime maintenance at cost. Sample development takes up to 30 days, while small or simple samples take 3–5 days. Sample fees can be refunded after a certain order quantity.
