NPK International Inc. manufactures, sells, and rents recyclable composite matting systems designed to provide temporary worksite access for customers in power transmission, oil and gas, pipeline, renewable energy, and construction industries. The company operates two revenue streams: renting composite matting systems with construction and site services (majority of revenue), and manufacturing and selling mats globally. The rental business primarily serves customers in the United States and United Kingdom, with the power transmission sector accounting for the largest portion of revenues, while mat product sales are distributed worldwide. The company competes against larger generalist equipment rental providers and a few specialized composite mat manufacturers by offering superior work surfaces and economics compared to traditional wood mats, supported by proprietary technology including patented mat designs and grounding systems.
