Sichuan Kexian Advertising: 20+ Years Legacy

Sichuan Kexian Advertising Limited Company, based in the manufacturing heartland of Sichuan, China, is an established industry pioneer. Over two decades, we have evolved from a local metal fabrication studio to an international industrial power in high-end structural signs.

We integrate spatial architecture, structural engineering, and light physics to manufacture solutions that outlast standard visual advertisements. For B2B clients, project engineers, and global procurement departments, Kexian offers an all-inclusive, factory-direct design-to-delivery lifecycle. Our in-house production guarantees rigorous quality control, shorter lead times, and structural certifications required by global building codes.

Our core manufacturing capabilities cover giant LED characters, dimensional non-illuminated metal letters, ultra-slim hotel doorway indicators, corporate pylon monoliths, and specialized lightboxes. We turn 2D designs into permanent structural landmarks.

We design our products with future-proof specifications, prioritizing sustainability, smart controls, and weatherproofing.

CE, UL, RoHS & FCC Compliance

Our engineering standards ensure that all electronic elements, LED modules, power drivers, and interior cables comply with global fire-safety and electrical regulations.

Weatherproofing & Durability

We use premium materials like SUS316 stainless steel, IP67+ waterproof LED strip lights, and anti-UV acrylics. These materials protect against extreme wind loads, temperature shifts, and rust.

IoT Smart Signage & Sensors

Our research focuses on integrating light sensors and programmable controllers. This allows building lettering to adjust brightness levels based on ambient daylight, saving energy.

Sustainable Architectural Alloys

We are transitioning to using recycled structural alloys and energy-efficient LEDs. This supports green building initiatives and LEED certifications for commercial projects.

Industrial Signage FAQ & Technical Insights

Get technical details on engineering, custom installations, global shipping, and material options.

How does Kexian ensure outdoor durability in extreme environments?
We use premium metals like 304 and 316-grade stainless steel, which resist rust in high-salinity coastal areas. Our LED modules are IP67-rated, meaning they are fully protected against dust and water immersion. We also apply high-grade UV-stable coatings to prevent acrylic components from yellowing or cracking under direct sunlight.
What electrical certifications do your illuminated signs carry?
All electronic elements, including LED ribbons, light modules, and power transformers, carry CE, RoHS, FCC, and UL certifications depending on your country's regulations. When manufacturing, we ensure that power drivers match local voltages (such as 110V-120V for North America or 220V-240V for Europe) to support safe installation.
Do you support architectural CAD files and custom corporate designs?
Yes, our design team works directly with standard vector formats like CAD (.dwg / .dxf), Adobe Illustrator (.ai), and CorelDraw files. We also provide full manufacturing drawings and 3D mockups. This ensures that proportions, structural studs, and wiring paths are finalized before production begins.
What is the minimum order quantity (MOQ) and production lead time?
Our minimum order quantity starts at just 1 piece. This allows B2B clients to test sample fabrications before committing to full-scale rollouts. Typical production lead times range from 7 to 15 business days, depending on project complexity and the volume of custom components.
