Sonotube® is a registered trademark product of Sonoco, and is an alternative method option for concrete column forming. Columns are fabricated using a reinforced shaping structure, and traditionally steel or fiberglass was used in the process. However, those materials are both heavy and inflexible and require careful treatment.
Sonotubes® are high quality heavy-duty cardboard structures into which concrete is poured to create a smooth-sided column. The tubes have to be able to withstand the pressure of concrete and have a smooth interior to ensure a flawless column wall finish. They are made with spiral wound fiber layers and adhesive bonding, and are extremely strong in cylinder form. Concrete columns are used in a wide variety of applications, and Sonotube® provides a cost-effective and efficient method of producing a variety of sizes of columns in terms of diameter and length. Short, wide columns are often used as bases for parking lot lamps, streetlights, street signals and deck posts. Tall columns are used for external decoration or roof support around buildings, foundational support in basements and warehouses, and many others. Read More…
