Material Mild Steel (MS): These drums are made from mild steel (a type of low-carbon steel), which gives them structural strength and durability.
Open Mouth / Open Head: Open mouth (or open head) means the drum has a removable lid. This design gives greater access to the inside, making it easier to put in or take out solids, semi-solids, or powders. These drums usually have a locking ring (lever or nut-bolt type) to secure the lid.
Capacity & Use: Typical capacities mentioned are around 210 liters for large industrial MS open head drums. These are commonly used to store and transport chemicals, powders, semi-solids, and industrial materials.
Variations & Specifications: The steel thickness may vary (for example, 0.8 mm to 1.6 mm depending on the requirements).
Internal finishing (e.g., epoxy coating, lacquer) is often possible to make drums compatible with different stored materials.
For shipping or hazardous materials, they may be made to comply with safety standards (e.g., UN performance test).
Easy Loading & Unloading: Since the lid is removable, it's much more convenient to fill with powders or solids and then empty them.
Cleaning: Easier to clean compared to closed or tight-head drums.
Flexibility: Good for different types of contents not just liquids.
