At Dutco Tennant LLC, we believe that modern cities require more than just access solutions — they need infrastructure that's intelligent, durable, and built to last. That’s why we bring the finest in ductile iron castings through our exclusive collaboration with Crescent Foundry, one of the most advanced ductile iron foundries in the world.
From cast iron manhole covers to gully gratings and trench solutions, our product range delivers performance you can trust in every environment — from highways and airports to industrial zones and smart cities.
Designed for Precision & Performance
Our ductile iron manhole covers and frames are manufactured using advanced foundry casting processes to ensure mechanical strength, fatigue resistance, and dimensional accuracy. Designed to comply with international standards, these covers are ideal for heavy-duty, high-traffic, and environmentally sensitive applications.
Complementing this is our range of gully gratings, engineered for optimal drainage and load-bearing capacity — keeping public and industrial areas safe and efficient.
