Professional Stamped Sign Engineering Services

YJ Sign Inc delivers expert stamped structural engineering for commercial signage across North America. With over 20 years of specialized experience and licensing in 49 states plus multiple Canadian provinces, we provide the structural calculations and engineer-sealed drawings you need for permit-ready signage projects. Whether you're installing monument signs, pylon signs, wall-mounted displays, or channel letters, our engineering team ensures your signage meets all structural requirements and local building codes.

Why Structural Engineering Matters For Your Signage

Every exterior sign visible from public roadways requires proper structural engineering to ensure public safety and regulatory compliance. Building departments nationwide mandate engineer-stamped drawings that demonstrate your signage can withstand wind loads, seismic activity, and environmental stresses specific to your location. Without these stamped calculations, you cannot obtain the permits necessary to install your sign legally.

At YJ Sign Inc, we understand the urgency of your projects. Our streamlined process delivers stamped engineering documents in as little as three days, depending on project complexity. We work directly with sign contractors, fabricators, and installers who need reliable engineering support to keep their projects moving forward. Our team has engineered everything from small blade signs to 60-foot pylons and structures exceeding 1,500 square feet.

Comprehensive Sign Engineering Services

Monument Sign Engineering

Monument signs create a powerful first impression for businesses, campuses, and developments. Our engineers design structural systems for monument signs of all configurations, whether you need augered hole direct burial, augered footings, spread footings, or base plate and anchor bolt connections. We calculate loads for single-pole and multi-pole configurations, ensuring your monument sign stands strong for decades.

Pylon Sign Structural Design

Tall pylon signs demand precise engineering to account for increased wind exposure and structural complexity. YJ Sign Inc provides complete structural analysis for pylon signage, including pole design, foundation specifications, and cabinet frame calculations. We engineer pylons with various foundation types and pole configurations, adapting our designs to soil conditions and local wind load requirements at your specific site.

Wall-Mounted Sign Engineering

Wall signs require careful analysis of both the sign structure and the building facade that supports it. Our engineers evaluate attachment methods, standoff distances, and wall construction details to ensure safe installation. We design anchorage systems for channel letters, cabinet signs, LED displays, and other wall-mounted applications, whether pinned directly to masonry or mounted on steel frames.

Channel Letter Calculations

Individual channel letters present unique engineering challenges, especially for larger installations or letters mounted at significant heights. We provide stamped engineering for channel letters in various mounting configurations, including wall-mounted, canopy-mounted, ground-mounted, glass-mounted, and parapet spider frame applications. Each installation receives the structural analysis needed for code compliance.

Our Engineering Process

We've refined our workflow to deliver high-quality engineering with minimal turnaround time. When you contact YJ Sign Inc, you'll work directly with our experienced team who understands the sign industry inside and out. We start by reviewing your sign drawings and project specifications to identify all structural elements requiring engineering.

Our engineers then perform detailed calculations accounting for dead loads, live loads, wind loads, and seismic forces based on your project location. We design foundations, structural frames, and attachment systems that meet or exceed local building code requirements. Finally, we prepare comprehensive stamped drawing sets with our professional engineer's seal, ready for immediate submission to building departments.

Throughout the process, we maintain open communication with our clients. If we identify potential issues or have questions about site conditions, we reach out promptly to keep your project on schedule. Minor revisions before final stamping are included at no additional cost, ensuring you receive exactly what you need for successful permitting.

Licensed Across North America

YJ Sign Inc holds professional engineering licenses in every U.S. state except Alaska, plus several Canadian provinces including Manitoba, Ontario, Alberta, and Saskatchewan. This extensive licensing allows us to serve sign contractors and businesses throughout North America without requiring multiple engineering firms for multi-location projects.

Our nationwide licensing is particularly valuable for chain retailers, franchises, and businesses with multiple locations. We can provide consistent engineering standards across all your sites while ensuring compliance with local building codes that vary by jurisdiction. Whether your project is in California, Texas, Florida, New York, or anywhere else in our service area, we have the credentials to stamp your drawings.

Fast Turnaround Without Sacrificing Quality

Speed matters in the sign industry, where installation deadlines often depend on business openings, marketing campaigns, or lease requirements. YJ Sign Inc typically delivers stamped engineering documents within three days of receiving complete project information. For urgent situations, we can accommodate rush requests to keep critical projects moving.

Our quick turnaround doesn't mean cutting corners. Every project receives thorough structural analysis by licensed professional engineers with deep expertise in signage applications. We've simply optimized our internal processes and built a team large enough to handle multiple projects simultaneously without delays. Our clients consistently praise our responsiveness and reliability.

Industries and Applications We Serve

Over two decades in business, we've provided stamped sign engineering for virtually every type of commercial application. Our portfolio includes signage for amusement parks, hospitals, airports, colleges and universities, stadiums, and high-rise buildings. We've engineered signs for festivals, temporary installations, permanent landmarks, and everything in between.

We work with C-45 license holders in California, ESC contractors in Texas, LSC and LSI professionals in Oregon, S-A Sign Installers in Tennessee, and licensed contractors in states with specific sign installation requirements like Minnesota, Rhode Island, Washington, and New York City. For states without specialized sign licenses, we coordinate with general contractors to ensure proper engineering documentation.
