The Safe Demystified – Mortise and Tenon Structure

You may have never imagined, but in a safe box that represents modern technology, also uses a traditional craftsmanship that dates back to thousands years of history. All CAPTAIN safe boxes use the Mortise and Tenon joint that has a history of 7000 years. It may sound irrelevant to modern technology but this structure actually improves the anti-theft features of safe boxes by significant quantities. 

What is the Mortise and Tenon joint?

It is a common structure seen in architecture, furniture and wooden equipment of ancient China, used to connect two pieces of wood. The tenon part works as a peg and is inserted into the mortis, which acts as a slot. Due to its perfect fitting design, no nails are required at all. The mortise and tenon joint reinforces the safe, as the protruding and concave parts slide into each other, playing a key role in the connection of the two adjoining pieces. 

Advantages of a Mortise and Tenon joint

The Mortise and Tenon joint is an ancient traditional craft that has a history of thousands of years. In the distant past when reinforced concrete and nails were still unheard of, people used the mortise and tenon structure to build houses and construct furniture. 

Although each component of a Mortise and Tenon joint is relatively thin, the structure can withstand huge pressure as a whole. It is not only secure, this structure can also be cleverly used to make wooden furniture and buildings more durable, stable and stronger. 

The nearly 1000 year old Pagoda of Fogong Temple in Yingxian Country, Shanxi, and the building group of “Forbidden City” with a history of nearly 600 years, all use the Mortise and Tenon structure, in which they still stand today. It’s hard not to admire the ancient’s greatness of intelligence and discovery. This craftsmanship is still commonly used in our lives now, in mahogany furniture and some luxury furniture. 

Mortise and Tenon Structure in Safe Boxes 

In all CAPTAIN safe boxes, the back plate and the box are connected by the tenon and mortise joint, and the back plate is embedded in the box and welded by gas shielded welding technology. The tenon and mortise assembly method is adopted to avoid the trouble of using nails and to avoid the nails from damaging the quality of the backboard. Ensuring the quality of the backboard can greatly improve the anti-prying and smashing ability of the cabinet and ensure the firmness of the joints.

According to the characteristics of the tenon and mortise structure, smashing the backboard from the outside of the safe will make the joint between the backboard and the box tighter, as the entire safe has MAX anti-smashing and anti-prying capabilities.

At the same time, CAPTAIN Safe adopts gas shielded welding technology, which uses gas to shield the welding area during the welding process, in order to improve the quality of the weld and reduce the heating of the weld.

The welding speed is fast, the heat-affected zone is narrow, the deformation of the weldment after welding is small, and there will be no bubbles (virtual welding) during the welding process, which will lead to unrealistic welding and further improve the firmness of the weld.

CAPTAIN Safe adopts the combination of tenon and mortise structure as well as gas welding protection technology. The perfect fusion of traditional skills and modern technology greatly improves the anti-theft performance of the safe.
