Explore our custom engineered 3D dimensional signs, illuminated channel letters, and architectural signage options tailored for B2B applications.
Technical insights into the procurement of large-scale architectural and outdoor marketing installations.
In modern commercial architecture and brand identity projects, physical touchpoints play a key role in public engagement. Large light up letters and custom dimensional structures are no longer just static display signs. They serve as interactive architectural features that strengthen brand recognition and act as visual landmarks. Real estate developments, entertainment districts, luxury hospitality projects, and massive public spaces require exterior signage systems that are durable, highly visible, and energy-efficient. As a leading manufacturer, Kexian produces signage systems built to withstand harsh weather conditions while delivering precise, high-performance illumination.
Procuring large light up letters on a global B2B level involves technical details like wind-load engineering, electrical safety certifications (UL, CE, FCC), and UV stability. Standard signage components often fail under heavy exposure to elements, causing LED degradation, discoloration, and structural issues. To prevent these failures, international procurement managers and structural engineering teams work directly with certified manufacturers like Kexian. Our design-to-delivery workflow ensures structural integrity and high optical performance, aligning with building codes in North America, Europe, and the Middle East.
Sichuan Kexian Advertising Limited Company, located in Sichuan, China, is an established industrial signage manufacturer with more than 20 years of experience in design, manufacturing, and international trade. We specialize in custom signage solutions, helping B2B buyers navigate projects from concept to final product. Our design and technical teams use modern engineering software to create illuminated letters that fit seamlessly with different architectural backgrounds.
Our catalog includes giant LED letters, marquee sign letters, backlit and front-lit channel letters, custom lightboxes, architectural neon signs, outdoor pylon signs, and complete direction systems. These products serve diverse applications, including global retail franchises, commercial offices, medical centers, hotels, educational campuses, and transit stations. Kexian helps clients streamline procurement by managing all metal fabrication, painting, LED assembly, and electrical compliance in-house.
B2B engineering details of large sign systems, including material specifications and electrical safety features.
We build our signage using high-grade marine alloys, such as 304 and 316 stainless steel, to prevent corrosion in coastal areas. For acrylic components, we use UV-resistant PMMA sheets. This keeps light diffusion clean and prevents yellowing or cracking when exposed to intense sunlight.
Large outdoor signs can experience high wind loads and internal heat buildup. Our engineering team calculates structural reinforcement using internal steel frameworks. We design ventilation paths to dissipate heat, helping to extend the operational life of the internal LED modules.
We utilize high-lumen, constant-current LED modules that feature IP67 or IP68 water protection. These systems are powered by certified drivers, such as Mean Well, which provide stable output, short-circuit protection, and comply with international energy standards.

Exporting large structural elements requires careful packaging and planning to minimize shipping volume and protect the finish. Kexian uses custom wood crates with shock-absorbing foam inserts for all shipments. This protects acrylic face plates and metal returns from vibration and impact during sea or air transit.
We work with international logistics providers like FedEx, DHL, and UPS for fast air freight, and handle ocean cargo forwarding for large projects. To make the import process easier, we provide complete customs documentation, including certificates of origin, material compliance sheets, and test reports.
Our hardware and products undergo inspection steps to meet electrical safety requirements for global markets. We hold certifications for CE, RoHS, FCC, and UL standards. Every illuminated sign runs through a continuous 100% active testing process before final packaging. This quality check helps verify electrical stability and thermal safety for each unit.
The signage industry is moving toward more energy-efficient and recyclable materials. Here is how Kexian is adapting.
We are testing and incorporating plant-based PMMA resins and fully recyclable aluminum alloys. This reduces carbon emissions during manufacturing and helps clients meet corporate sustainability goals.
We are integrating smart controllers that support real-time monitoring, DMX program adjustments, and automatic light level adjustments based on ambient environment conditions.
Our engineering team is designing self-powered freestanding metal landmark signs, combining solar film technologies with standard battery setups to reduce grid reliance.
