Explore our flagship catalog of engineered illuminated signs, manufactured with micrometric precision at our Chinese industrial facilities.
In the contemporary digital landscape, physical architecture remains the primary anchor of real-world authority. Custom lighted metal letters serve not merely as structural coordinates, but as high-fidelity vectors of brand prestige. Across commercial real estate, luxury retail environments, administrative headquarters, and public transit nodes, visual signage plays a vital role in consumer pathfinding and brand recall.
Sichuan Kexian Advertising Limited Company, established in Sichuan, China, leverages over 20+ years of industrial excellence. We operate a fully integrated, state-of-the-art facility covering 6,600 square meters, fusing advanced materials science with smart optoelectronic systems. Our specialized capabilities stretch across design engineering, metallurgical processing, high-grade LED potting, and strict global distribution pathways.

A deep dive into the engineering choices that define structural longevity and high visual fidelity.
We source certified SUS304 and SUS316 austenitic stainless steel. The chemical composition, rich in chromium and nickel, ensures natural oxide passivation layer regeneration, preventing galvanic and pitting corrosion in harsh environments.
Our custom LED assemblies operate with high color rendering indices (CRI ≥ 85) and optimal luminous efficacy (up to 120 lm/W). We use PMMA diffusers with optimized light transmission ratios to eliminate hot spots.
High-efficiency LED setups produce heat that degrades light output. We mount our PCBs on thermal-conductive paths, using IP67/IP68 polyurethane resins to block water molecules while keeping thermal resistance low.
The signage industry is moving past static illumination. Our R&D division is actively working on integration paths for IoT-based visual control networks. By integrating light-sensitive resistors (LDRs) and programmable smart drivers directly onto our architectural chassis, next-generation signage from Kexian will dynamically adjust brightness depending on real-time ambient lux levels, significantly reducing power draw and extending light source operational lifetimes to over 70,000 hours.
Aligning raw manufacturing capacity with high-performance global supply chains.
We provide full design, production, and shipping logistics under one roof. With samples starting at an agile MOQ of 1 piece, our clients can test materials and illumination outputs before starting volume runs.
Our internal staff includes design engineers, manufacturing specialists, and electrical technicians who turn complex vector artwork into structural products built to survive wind loads and seismic variables.
As a direct manufacturer, we offer complete tracking during production. We share photo and video milestones at each phase, giving you total oversight and a direct loop to request adjustments.
Our signage goes through rigorous quality control to meet global standards. We maintain CE, RoHS, FCC, and UL compliance, allowing you to pass complex municipal inspections with ease.
We are a certified partner for international brands like Midea, Gree, JD, and Liansu. We scale our output to meet demanding rollout schedules without compromising quality.
Precision manufacturing relies on high-tier automation. We invest in top-class CNC, laser, and printing equipment to maintain precise control over tolerances.
A step-by-step breakdown of how Kexian transforms raw metal sheets and optoelectronic modules into high-grade custom signages.
1. Precision Bending
Automated CNC side wall bending defines the letter contours with high dimensional accuracy.
2. Fiber Laser Cutting
High-density fiber laser beams slice the metal plates, ensuring clean, burr-free edges.
3. Laser Welding
Concentrated light fusion links the metal faces and returns, preventing heat deformation.
4. High Precision UV Printing
Applies high-durability, UV-cured pigments onto materials, preventing fading.
5. Structural Assembly & Welding
Final structural reinforcement and integration of the IP-protected optoelectronic components.Exporting structural signage systems requires careful adherence to international electrical safety laws. Every luminous assembly fabricated by Kexian undergoes complete testing before packaging. Our products hold certificates for key target markets, including CE, FCC, RoHS, and UL listings.
To ensure secure, timely delivery, we work closely with major international logistics integrators: FedEx, DHL, UPS, and EMS. Whether shipping small individual letters or large-scale, modular architectural framework signs, our packaging is designed to handle multi-modal transit stresses, keeping your investment safe.
Different architectural contexts require specific styles and engineering configurations.
Modern hotels require clear, premium identification systems. From high-visibility illuminated rooftop lettering that stands out against city skylines to matching interior corridors, custom acrylic and metal door signs help guide guests and reinforce branding.
For corporate facades, brushed stainless steel backlit letters project stability and trust. By choosing high-durability metals, corporate hubs reduce maintenance cycles while projecting a professional image.
Industrial complexes, parkways, and municipal zones rely on high-visibility hazard warning plates and directional panels. Using UV-resistant coatings and stainless steel framing ensures these signs remain legible in harsh weather.
Clear, direct answers to common engineering, installation, and procurement questions.
Our premium LED modules are rated for approximately 50,000 to 70,000 hours of continuous operation. This equates to over 11 years of active runtime if powered for 12 hours daily. To achieve this, we use constant-voltage Mean Well drivers that prevent voltage spikes, along with internal heat dissipation pathways.
While SUS304 provides excellent resistance for typical inland environments, seaside or coastal installations require SUS316. SUS316 contains 2-3% molybdenum, which protects against chloride-induced corrosion and pitting from salt spray. We recommend SUS316 for any site within 5 miles of a saltwater coastline.
To prevent brightness dimming on distant letters, we divide long letter arrays into parallel circuits rather than wiring them all in a single series. Standard systems operate on 12V or 24V DC lines. If the distance from the power supply exceeds 15 meters, we increase the conductor gauge (AWG) or use multiple power supplies to ensure even light output.
For masonry, concrete, or drywalls, we supply threaded mounting studs that sit inside drilled holes filled with structural adhesive. For glass curtain walls where drilling is not possible, we design custom structural aluminum raceways or use high-strength double-sided industrial structural tapes combined with structural silicones to secure the letters safely.
Select from our customized commercial designs. Built for high performance and outdoor durability.
At Kexian, we combine twenty years of manufacturing experience with premium optoelectronic engineering. Let our team turn your architectural concepts into reliable, high-performance physical signage. Reach out today for technical advice, material sample requests, and detailed project pricing.
