Laminated steel lock body padlocks have bodies that are made up of plates of steel fastened with steel rivets and are used for securing goods. They're not as strong as solid body locks as the steel rivets can be tampered with. These padlocks are commonly used in indoor applications as they are less corrosion resistant than brass, chrome-plated, stainless steel, covered, aluminum, and zinc-plated steel lock body padlocks. They have a standard shackle that is less than 1.5 in in vertical shackle clearance and are keyed alike, so all locks in the set open with the same key.
