Sonotube concrete forms stand strong as the most economical way to create round columns for buildings, entrance ways, structural columns, light posts and other commercial and residential structures.
Sonoco engineers applied a century of leadership in design, technology and manufacturing to create a high-strength, rain-resistant design for Sonotube forms. The technology allowed Sonoco to reduce the weight of the forms, making them easier to handle, set, strip and discard. And now with RainGuard technology, Sonotube forms stand strong even in wet weather—allowing contractors to set today and pour tomorrow.
