Made In The USA

An alternative to a shelter when you are looking for open coverage is our transit canopy, which can be designed to meet your dimensional & height requirements. The canopy shown is offset to allow for clear foot traffic and lighting for 24 hr use. Benches are also available upon request. This design does require foundations to be set in advance to support the steel structure.
