Magnesium panel joints: tongue-and-groove and middle-aluminium
The joint is the part of a cleanroom panel that the room sees and cleans every day, and it is also the part that most often decides whether a panel suits a room. This page lists only the joint facts that the source material lists for magnesium panels, and it gives no drawing dimensions, because the source material gives no drawing dimensions for publication.

Handmade joints
Handmade magnesium panels are listed with two joint options: a tongue-and-groove connection, or a middle-aluminium connection. The handmade MgO rock wool panel adds a third listed option: a full female joint with middle-aluminium connection. Those are the listed handmade joint facts, and they are stated per model on the model pages as well.
The practical difference is in site work and appearance: a tongue-and-groove joint and a middle-aluminium joint are installed differently and look different in the finished wall, and a full female joint with middle aluminium is a different joint again. State the joint your project specifies in the inquiry, and ask for the joint detail for that model, rather than assuming that any handmade joint will suit any room.
Machine-made joints
Machine-made magnesium panels install by tongue-and-groove joint, at the 1150-type module. That single joint, repeated across the machine-made range, is what makes machine-made installation fast and uniform: the same joint, the same module, and the same site procedure for every panel in the run.
The trade-off is flexibility: a uniform tongue-and-groove module suits regular layouts, while a room with varied widths or planned openings may need the handmade joint options instead. The handmade-versus-machine-made guide explains that trade-off, and this page does not recommend a joint without knowing the room.
What to confirm about a joint
Confirm the joint type, the joint sealing and cleaning guidance for that model, and whether the joint detail affects the room's cleanliness or cleaning regime. For biopharma and cosmetics rooms, joint tightness and cleanability are selection criteria in their own right, as the application pages explain.
