We are your one stop source for highly innovative prefabricated buildings. Since 1969 our modular buildings, mezzanines, portable buildings, toll booths and smoking shelters have been used for thousands of unique construction applications across North America and throughout the world. We provide our customers with cost effective, highly functional, easy to assemble alternatives to conventional construction.
Today, Porta-King manufactures five different types of prefabricated buildings and shelter systems that include high-level ballistic rated construction. We manufacture eight different types of modular wall systems, structural steel mezzanines and towers.
Porta-King Building Systems offers more prefabricated and modular buildings than any other manufacturer. All of these products have attributes that support the efforts of those companies and organizations that want to incorporate a sustainable design philosophy into their business. In addition, we can support various elements toward securing LEED certification for both new and retrofit construction projects with all of the products we manufacture.
We believe the key to our success has been our ability, and willingness, to adapt to new industry trends. Since our inception we have responded to our customers by introducing many "industry firsts" to address these developing trends in the modular and prefabricated construction industry. This includes new products, modification to existing products which includes adaptation to address new building and energy code requirements. Many of these changes have resulted in new patents.
