Why Are Steel Doors Used on Shipping Containers?

Shipping container steel doors are heavy-duty doors designed for use on shipping containers, providing secure and reliable entry and exit points. These doors are typically made from high-quality steel, offering strength and durability to withstand the rigors of transport and storage. They are often equipped with locking mechanisms, such as multi-point locking systems or padlock fittings, to enhance security. These doors are crucial for safeguarding goods during transit or while in storage, preventing unauthorized access, and providing protection against the elements. The design and construction are specifically engineered to handle the weight, wear, and environmental exposure of shipping containers.

 

 

Shipping container steel doors can last anywhere from 15 to 30 years, depending on factors such as environmental conditions, maintenance, and the quality of the materials used. The steel construction is durable and resistant to physical wear, but exposure to moisture, saltwater, and extreme weather can accelerate rust and corrosion. Regular maintenance, such as painting, cleaning, and checking locking mechanisms, can help extend the lifespan of the doors. In marine environments, where containers are exposed to salty air and humidity, corrosion resistance becomes particularly important, and some steel doors come with coatings or treatments to protect against rust and environmental damage.

 

Indeed, steel security doors for shipping containers are usually made to withstand corrosion, albeit the degree of resistance varies based on the materials and the environment in which the doors are utilised. Many steel doors are protected from rust and deterioration by exposure to moisture, humidity, and saltwater, especially in coastal or marine areas, by galvanised coatings or anti-corrosion treatments. For further protection, some models could also feature corrosion-resistant metals or powder-coated finishes. Frequent upkeep, such cleaning and repainting, can also help the door last longer and stop rust from forming.
