❓ Technical Procurement & Engineering FAQ

Direct technical answers addressing ingress standards, electrical compliance, color rendering, and project lead times.

► What certifications accompany your luminous signage for North American and European building codes?

All custom luminous systems exported by Kexian are engineered with components complying fully with UL 48 (Electric Signs), UL 8750 (LED Equipment for Use in Lighting Products), and European CE / RoHS electrical safety directives. Power units are UL Class 2 or MeanWell IP67 drivers, ensuring safe low-voltage operation and straightforward compliance inspections on commercial sites.

► How do your factories ensure signage durability against UV exposure and water ingress?

Exterior installations employ marine-grade 304 or 316 stainless steel with automotive-grade AkzoNobel polyurethane powder coatings that resist peeling, chalking, and salt-fog corrosion. Translucent acrylic elements utilize cast virgin PMMA with integrated UV-blockers. Internal modules are sealed to IP67/IP68 standards using automated silicone encapsulation, backed by weep-hole drainage channels.

► What is the standard factory lead time for custom-engineered prototypes and bulk rollouts?

Standard prototype verification and 3D shop drawings require 24 to 48 hours. Production lead time for standard bespoke orders typically spans 5 to 9 business days, while volume rollouts for multi-location brands are staged in 15 to 20-day delivery batches. Air-express delivery via DHL/FedEx takes 3 to 6 days worldwide, while ocean consolidations take 18 to 28 days.

► Do you offer turnkey installation templates and technical electrical diagrams?

Yes. Every custom luminous sign order ships with a full-scale 1:1 computer-plotted mounting template (paper or vinyl), stainless steel stud bolts, standoffs, waterproof connectors, and a comprehensive electrical wiring schema showing low-voltage wire paths, power supply capacities, and terminal loads.
