Discover our top-tier custom fabricated signboards, 3D illuminated letters, and architectural pylon solutions engineered to boost brand visibility across the globe.
For global retail giants, corporate offices, public municipalities, and premium hotel franchises, visual display systems are more than just design components. They serve as a critical vector of brand equity, environmental design, and offline traffic navigation. In B2B sourcing, selecting the proper "Large Letters Light Up" manufacturer is not a simple transaction. It requires evaluating technical specifications, safety compliance, materials performance, and supply chain scalability.
From the standpoint of Google Quality Standards, information depth means detailing the exact physics of light diffusion, material integrity under wind load pressure, and electrical efficiency. Selecting a supplier requires inspecting how materials like 304 stainless steel and PMMA (polymethyl methacrylate) acrylic react to thermal expansion and environmental stress. Custom lettering must remain structurally stable, color-fast, and luminous over thousands of operating hours.
Sichuan Kexian Advertising Limited Company, based in Sichuan, China, is an established advertising signage pioneer with a distinguished history spanning over 20 years. Our company features a unified process integrating creative design, engineering layout, custom manufacturing, and global logistics. We support partners looking for custom signage as well as bulk OEM/ODM requests, handling design, fabrication, and final testing in-house to protect production schedules and quality.
By managing all operations within our manufacturing facilities, Kexian keeps total control over structural tolerances and material performance. Our engineering team combines industry experience with specialized drafting software to develop sign solutions that balance clean visuals with structural stability. Our product range includes Giant LED Letters, marquee letters, illuminated and non-illuminated channel letters, custom light boxes, custom neon signs, indoor hotel numbers, pylon signs, and complex urban guide systems.
Our factory capabilities, quality control processes, and global footprint provide the operational capacity required to support demanding B2B accounts.
Quality execution relies on manufacturing technology. Our 6600 square meters manufacturing facility features precision machinery that enables tight dimensional tolerances, clean weld lines, and consistent acrylic shapes.
Our factory maintains quality standards throughout the fabrication cycle. Every process—from structural shaping to electronic configuration—is monitored to confirm it meets engineering tolerances.

Our architectural signage solutions are certified under international standards to support building code approvals and ensure environmental safety. Our products comply with CE, RoHS, FCC, and UL standards. We implement a rigorous test process where all products undergo 100% operational testing, including 24-hour heat cycling and wet environmental simulation tests prior to packaging.
Over the past two decades, Kexian has established supply partnerships with several enterprise brands, including Midea, Gree, JD (Jingdong), and Liansu. These partnerships reflect our ability to manage bulk requirements and meet detailed design guidelines.
Custom illuminated letters serve different functions depending on the industry and installation location. We design and construct signage tailored to the mechanical and environmental needs of each application.
In retail, storefront signage uses specific lighting to attract traffic. Our front-lit and sidelit channel letters utilize optical diffusers that eliminate LED hot spots, maintaining even lighting across the face of the logo.
Hotel environments require clean architectural details. We build back-lit room numbers, directional guides, and logo signs using stainless steel finishes and custom LED panels to fit upscale interior schemes.
Large exterior pylons and public signs are built with structural steel cores to resist wind load pressures. Our structural engineering designs meet municipal codes and stand up to severe weather conditions.
Exporting structural signage internationally requires specialized packaging and shipping coordination. Kexian uses custom wood crating with high-density foam supports to prevent structural and surface damage during transport.
We work with international logistics providers—including FedEx, DHL, UPS, and EMS—to offer flexible delivery methods, whether shipping small express samples or multi-container sea freight orders. We provide customs documentation support to ensure smooth import processing.
With clients in over 100 countries, we understand regional customs requirements and electrical standards, helping to avoid project delays during installation.
Our design and development roadmap focuses on incorporating smart controls and sustainable materials into our custom sign systems.
We are integrating high-efficiency LED modules that lower power usage by up to 35% while keeping the same level of brightness. This helps businesses meet their corporate sustainability and environmental targets.
By integrating smart photocells, signs can automatically adjust their brightness based on ambient light levels. This maintains clear visibility in bright daylight while preventing excessive glare and reducing energy consumption at night.
We are testing recycled PMMA sheets and low-emission metal finishes. Our goal is to reduce environmental impact across our product lines without affecting structural durability or outdoor lifetime.
