The box is suitable for storing sand, light gravel and salt indoors and outdoors. It is made of durable PE plastic, which is recyclable. We can customize the colors according to the customer’s wishes. The main colors we use are green, yellow and faux marble. The boxes are equipped with a locking feature. The grid box is a good solution for keeping anti-slip materials in places where they may be needed in an emergency, such as private houses, apartment buildings, bus stops, train stations, parking lots, important junctions, uphill and downhill streets, etc.
