Seneca Architectural Products, Inc. was founded 17 years ago with a clear mission in mind: to represent and distribute only materials, systems and manufacturers of the highest quality and value to the designer and builder communities. By selecting only the products we believe in, we deliver our product lines with the attention, intelligence and passion they deserve.

Seneca API is not an indiscriminate collector of product lines that knows or has little interest in the material, its technical and design capabilities, or the people who use it. Rather, we are a comprehensive resource to the design and contracting communities. By offering the very best in products, as well as technical support in a prompt professional manner, we deliver on our promise to make a difference, the Seneca Difference, in all the projects we are involved.

With centers in Central Phoenix and Northern Arizona, Seneca API works with architects, builders and contractors throughout the state of Arizona & The Southwest. Our wide range of product offerings include copper and aluminum wall and roof claddings; stucco and EIFS; sun screens and louvers; plaster, GFRG & GFRC domes, vaults and fabrications and imported Italian plasters.
