Explore our flagship structural LED letters, luminous marquees, and dimensional stainless steel signs engineered for high-performance deployments.
In the contemporary landscape of experiential marketing, retail architecture, and corporate brand activations, visual impact is directly correlated with engagement metrics. Large light-up numbers have transitioned from simple event props to critical brand touchpoints. Utilizing state-of-the-art solid-state lighting (SSL) and laser-cut structural metals, these dimensional assemblies command physical presence and drive organic social sharing, offering brands high-yield physical-to-digital conversions.
From an architectural integration perspective, specifying large-scale numeric elements requires an understanding of structural physics, photometrics, and metallurgical engineering. Event hire operators and multinational corporations demand systems that are not only visually immaculate but are designed for continuous mechanical cycling, structural stability in high wind load zones, and strict electrical compliance. Sichuan Kexian Advertising Limited Company designs, engineers, and fabricates these structural assets, bridging the gap between bespoke visual artistry and mass-scale industrial reliability.
SEO Insight & User Intent: Global search patterns reveal that institutional buyers look for critical product attributes: safety certification (UL/CE), modular structural assembly, weatherproofing specifications (IP ratings), and logistics support. Finding a true manufacturer avoids broker markups and ensures structural safety.
Delve into the structural chemistry, electrical configurations, and mechanical design components that define our commercial-grade dimensional products.
We source heavy-gauge SUS304 stainless steel and aviation-grade 5052 aluminum alloy. The metallic sheets undergo high-performance fiber laser cutting to within a tolerance of ±0.05mm, followed by computerized press-brake bending to ensure seamless returns and structural rigidity up to heights of 3 meters without inner frame buckling.
Utilizing high-lumen, bin-selected Epistar SMD2835 LED modules with CRI > 85 and L70 lifetime values exceeding 50,000 hours. The luminous pathways are engineered with secondary optics for uniform, shadow-free diffusion. Color consistency is maintained across production batches to within 3 steps on the MacAdam ellipse.
Equipped with MeanWell or Rainproof UL/CE certified constant-voltage class 2 power supply units. The internal cavities of our marquee structures are optimized with thermal ventilation pathways, preventing LED junction temperature spikes, preserving luminous efficacy, and preventing chromaticity shift over prolonged usage.

How Sichuan Kexian integrates vertical supply lines and advanced automation to deliver unbeatable value to global enterprise customers.
The global competitiveness of Kexian Advertising lies within our direct access to China's electronics and metallurgy ecosystems, combined with our rigorous in-house manufacturing process. Based in Sichuan, we leverage localized raw materials with deep CNC machinery automation, enabling us to deliver premium large-scale signage at a fraction of the cost of localized Western fabricators.
By keeping every phase of production—including heavy cutting, channel bending, welding, powder coating, and LED assembly—under one roof, we eliminate intermediate processing delays. Our operations support dynamic prototyping with a low MOQ of just 1 piece, scaling up to mass production for international retail chains. Furthermore, we provide global clients with visual production tracking. Buyers receive high-resolution media and testing telemetry at each milestone, ensuring transparency and total control over quality and timelines.
Supply Chain Security: Our long-term logistics agreements with carriers like FedEx, DHL, UPS, and premier ocean shipping lines guarantee guaranteed transport times, dynamic customs handling, and robust drop-testing-proof packaging.
Architectural installations in public spaces require strict adherence to international building codes, wind calculations, and safety standards.
All internal electrical circuits are designed in accordance with UL 48 (Standard for Electric Signs) for North American markets and the Low Voltage Directive (LVD) for Europe. By utilizing Class 2 low-voltage secondary outputs (12V/24V DC), the risk of electrical shock and fire is minimized, making our products safe for high-traffic environments.
For outdoor installations, our large light-up numbers are constructed with double-sealed structural joints, drainage outlets, and fully encapsulated silicone LED modules. These features prevent moisture ingress, enabling them to operate reliably in rainy, snowy, or coastal high-humidity environments.
Freestanding outdoor numbers are engineered to withstand localized wind pressures. Our design team conducts structural calculations based on surface area and expected wind speeds to specify rear supports, base weights, and anchoring points that prevent tipping and ensure safety in public venues.
Minimizing Total Cost of Ownership (TCO) through modular packaging, robust crating, and direct international transit links.
For international buyers, freight costs and potential transit damage represent the highest risks in large signage procurement. Sichuan Kexian mitigates these risks through optimized product design and high-standard export packaging. We offer modular "knock-down" assembly designs for large-scale numbers, allowing letters over 2 meters tall to split into smaller segments, significantly reducing shipping volume and costs.
Every shipment is packaged inside heavy-duty, multi-layered export crates lined with high-density EPE foam. All metal edges are protected, and electrical components are sealed in anti-static moisture-barrier bags. Working with FedEx, DHL, UPS, and trusted freight forwarders, we provide customs documentation, certificate clearance validation, and tracking from our Sichuan factory to your doorstep or event venue.
Corporate Procurement Value: Kexian serves as a trusted partner for Fortune 500 corporations, including Midea, Gree, JD, and Liansu. Our systems are built to meet rigorous compliance audits and high-volume demand cycles.

Technical answers to common questions asked by procurement professionals, event managers, and structural engineers.
For standard custom orders of large light-up numbers, our production lead time is typically 7 to 10 working days after structural drawing approval. High-volume container orders or complex dynamic programmable signage projects may require 15 to 25 days. We also offer expedited lanes for urgent corporate events.
We configure each signage project with power supply systems tailored to the destination country's grid—such as 110V AC for North America or 220V-240V AC for European and Oceanian markets. All units utilize step-down transformers to output a safe 12V/24V DC to the light source. Plug types are specified to match the destination country's outlets.
Our products can be certified with UL, CE, FCC, and RoHS marks depending on customer requirements. All electrical components, including LED modules, internal wiring, connectors, and power supplies, carry individual certifications. Completed sign assemblies also undergo a 100% load test and thermal burn-in cycle before shipment.
Yes. As a direct manufacturer with an in-house design team, we fabricate custom structures using vector files (DXF, AI, CAD). We can match corporate brand guidelines, recreate custom typography, and integrate corporate logos directly into the dimensional structure.
For long-term outdoor installations, we recommend heavy-gauge SUS304 stainless steel or 5052 aluminum alloys for the outer casings, combined with double-sealed acrylic faces and IP67-rated waterproof LED modules. These materials prevent rust, corrosion, and water intrusion, even in harsh weather conditions.
We pack all products in custom-built plywood crates with high-density EPE foam padding. Foam corners protect all edges, and the entire unit is wrapped in moisture-resistant film. This heavy-duty packaging helps protect the signs during sea freight, air freight, and multi-modal transit.
