Hi, I am Kiki, How can I help you?
Building signs come in many shapes and sizes, including channel letters and backlit options. Because they are not just a good choice but an essential way to communicate with your customers and clients boldly and visibly, these large-format, weather-resistant, and durable signs help you achieve exactly that.
Place your brand at the center of attention with custom building signs showcasing your company name and logo. We offer a large selection of custom building signs to help you reach your branding goals.
As a manufacturer of smart park signs, the smart park solution provided by COSUN SIGN is based on the concept of "Internet + smart park management", integrating the office building sign and guidance system into the internal operation platform of the park, and unifing the supervision of data, and integrates the API data docking of information equipment such as security, convenient access, facility management, asset management, environmental space, and park intelligent operation center. Building signage not only provides a full range of intelligent management for the park but also injects new impetus into the sustainable development of the park. Through the smart park signage and guidance system, the park can be helped to achieve digital transformation and upgrading.
The term “building sign” encompasses all types of displays installed on a building, whether pin-mounted, flush-mounted, or illuminated. There are numerous styles of building signage designed to enhance your branding and meet your business needs.
| Building Top Signs | Building Letters |
| Highlight your building and make your establishment instantly recognizable with prominent custom signage. Displaying your company name on top of a building increases visibility and helps reach a wider audience. | We offer a wide variety of building letters, including pin-mounted options, crafted from durable materials and available with or without illumination to suit your design preferences. |
| Illuminated Building Signs | Building Logo Signs |
| Illuminated signs create a striking spotlight for your storefront. For continuous brand promotion, LED-lit building signs offer an energy-efficient and highly effective advertising solution that draws attention day and night. | Logo signs are essential for gaining recognition, especially in busy urban areas. 3D logo signs can be placed on rooftops, above entrances, or anywhere on your building to maximize visibility and reinforce your brand identity. |
| Building Blade Signs | Custom Building Signs |
| Blade signs extend from the wall, providing double-sided visibility to guide customers to your location. They can be constructed from durable materials and offered in illuminated or non-illuminated versions, depending on your requirements. | Benefit from fully customized building signage solutions, no matter the complexity. As a leading sign company, we create signs tailored to your unique vision, ensuring your message reaches your audience effectively. |
| Office Building Signs | Restaurant Building Signs |

The right signs work as silent salespeople, consistently promoting your brand and attracting diners. |
| Store Building Signs | Hospital Building Signs |
