Below is a list of Industrial Drums manufacturers from Harrisburg, Pennsylvania. Industrial drums are large, cylindrical industrial containers that are mainly used for shipping and storage applications. One of the oldest types of containers, industrial drums are primarily for transporting and storing bulk goods, which are most often liquids. As a result, industrial drum manufacturers often strengthened their drums with corrugations, called reinforcing rings, of the thickened material at each quarter of the drum to strengthen the sides and prevent denting or puncturing when rolled or turned.
