Denso North America Inc. manufactures a wide variety of anti-corrosion and sealing systems. Our U.K.-based parent company, Winn & Coales, was founded in 1883, and we released the renowned Denso tape, which protects buried steel pipelines against corrosion, over 80 years ago. Our products solve sealing problems in even the most challenging environments, including underwater and underground, and offer long maintenance-free service lives. Our dedicated and experienced team offers our customers technical support and on-site guidance, wherever your business happens to be.
