Specifications and dimensions of our ballast sandbags
What Are Sandbags for Signs?
Not all sandbags are made for flood control. Many are specifically designed to stabilise signs and other traffic safety equipment, providing reliable weight to keep them secure and in place.
Common materials include polypropylene sandbags, PVC sand bags, jute sand bags, depending on different application.
Filled with sand, gravel, or other fillers, it becomes a simple yet effective way to ensure stability and safety in different environments.
