Explore Our Facility
Discover how our vertically integrated design process, state-of-the-art machinery, and direct factory-to-buyer models provide unparalleled cost, speed, and safety advantages.
We manage everything in-house, spanning design, custom drafting, manufacturing, and direct global logistics. Our operational setup accepts a minimum order quantity (MOQ) of just 1 piece, paired with robust sampling pipelines, saving international clients both time and unnecessary structural markup costs.
Our team includes expert spatial designers, certified engineers, master metalsmiths, and precise quality-assurance managers. This skilled workforce converts sophisticated, large-format sign designs into durable structures capable of handling high wind resistance and thermal cycles.
By owning our manufacturing facilities, we offer transparency through live visual tracking. Clients receive real-time updates and HD product captures at each step, from metal cutting and laser welding to paint finishing and electronic installation, ensuring perfect execution before shipment.
All items comply with strict international regulatory standards, carrying certifications like CE, RoHS, FCC, and UL. Our signage systems undergo extreme climate exposure tests, high-voltage load inspections, and outdoor water ingress tests (IP65 to IP67) to ensure long-term outdoor performance.
We are a trusted tier-1 strategic supplier for Fortune 500 companies and prominent brands, including Midea, Gree, JD, and Liansu. Our large-scale production line is built to handle volume commercial programs while maintaining consistent output quality across every shipment.
Our long-term partnerships with FedEx, DHL, UPS, EMS, and specialized ocean freight lines allow us to offer secure and flexible delivery configurations. From prototype express shipments to containerized shipping, we handle customs clearance and delivery to sites worldwide.
We invest in state-of-the-art CNC, fiber laser, and high-precision bending machinery to maintain tolerances under 0.05mm across all sign types.
High-speed milling cutter for solid acrylic mini letters. Creates clean, crystal-clear edges that optimize light scattering for perfect backlit and side-lit signs.
Automatic bender designed for deep-flange giant metal letters. Ensures precise, sharp angles and smooth curves for heavy-gauge aluminum and steel return casings.
Industrial-grade fiber laser cutter for stainless steel, titanium, and brass sheets. Provides clean cuts and tight joints without heat distortion.
High-resolution flatbed printer with curing system. Delivers weather-resistant, non-fading graphics directly onto acrylic, glass, and metal surfaces.
Precision laser cutter for custom acrylic face panels. Seals edges instantly to create high-gloss finishes that protect outdoor signs from dust and moisture.
Concentrated beam laser welder for joining light-alloy returns. Produces micro-joints that require minimal polishing and prevent corrosion.
Highly precise CNC bending equipment designed to fold complex profiles. Prepares components for flawless integration with light box assemblies and signage return structures.
Our commitment to excellence is backed by global testing standards. Every sign system is certified to operate safely under harsh municipal conditions.

When purchasing custom giant light up letters, structural safety and electrical compliance are critical concerns for global operators. Installing non-certified electrical equipment can lead to structural failures, building code violations, and rejected insurance claims. In North America, signage installations must strictly comply with UL 48 (Standards for Electric Signs) and the National Electrical Code (NEC). In Europe, compliance with the Low Voltage Directive (LVD) 2014/35/EU and CE markings is required.
Electrical Component Safety: Our production line ensures all LED modules and power drivers are UL or CE certified. Our electrical layouts feature built-in short-circuit protection, over-current cutoff, and auto-reset thermal limits. We also match regional power standards, configuring systems for 110V/60Hz in the US and 220V/50Hz across EU markets, using premium Mean Well IP67 power units.
Structural & Wind Resistance: Large outdoor letters function like sails in heavy winds. We run wind-load calculations using FEA (Finite Element Analysis) models to determine the best internal steel reinforcement frame. This ensures our letters can withstand winds up to 120 mph, making them ideal for high-rise facades and open coastal areas.
Purchasing direct from our factory in Sichuan, China, offers significant cost and production advantages over sourcing locally in the US or Europe. China's integrated industrial supply chain combines raw material access, advanced laser cutting tools, automated metal bending machinery, and skilled labor in one place, creating a highly efficient manufacturing environment.
Enterprise procurement departments look for reliable manufacturing partners who can protect their brand identity across multiple locations. At Kexian, we address these corporate requirements by offering strict color matching (using PMS/RAL color systems) and precise logo reproduction.
Accurate Corporate Branding: We use high-precision spectrophotometers to check powder coating finishes and paint colors under standardized lighting. This guarantees that whether a sign is installed in New York, London, or Tokyo, the brand's signature colors remain perfectly consistent.
Comprehensive Documentation: We provide detailed submittal packages for corporate projects, including AutoCAD engineering drawings, electrical schematics, installation templates, and material data sheets. This documentation speeds up local permitting and simplifies the installation process.
Giant marquee and illuminated letter installations serve as high-impact visual landmarks across a variety of commercial and civic spaces. Understanding the installation environment helps us select the best materials and illumination configurations for each project:
The commercial signage industry is adopting smarter, more energy-efficient technologies. Modern commercial properties want signs that consume less energy, integrate with building automation platforms, and require minimal maintenance over their lifespan.
Smart Control Integration: We configure our LED sign systems with intelligent control systems, including DMX controllers, Bluetooth/Wi-Fi modules, and automated photo sensors. This allows building managers to schedule brightness levels, coordinate dynamic color sequences, and track real-time power consumption.
Eco-Friendly Manufacturing: In response to the demand for sustainable building standards, we use lead-free solder, recyclable acrylic formulas, low-VOC powder coatings, and high-efficacy LEDs (yielding up to 130 lumens per watt). This helps properties earn LEED credits while reducing their operational energy costs.
