A New TWIST on Seamless.

The Steel Door Institute requires that all doors meet rigid test requirements, in order to maintain the highest quality standards for life safety and security. In the SDI Twist Test for steel doors, a door must meet the following criteria in order to pass the test and meet the standard set forth: At 300# of force, the door must deflect no more than 1-1/4" in the opening. When the pressure is released, the permanent deflection of the door must not exceed 1/8" in the resting state.

Mesker Door Midam Metal Design Hardware


All seamless doors are the same. – FICTION. Some “seamless” doors are seamed-edge, using putty to fill the vertical seams. Other “seamless” doors have a combination of a stitch-weld and putty to fill the seam. All NVS doors from Mesker are fully welded, seamless, with no putty or filler.

Hiding the seam in a door edge is just for looks.
- FICTION. Although a fully welded, seamless door looks much better than a standard seamed-edge door, it is also much stronger, and will withstand the abuse of high traffic areas. That's why architects specify the new NVS door from Mesker. You get the best of both worlds, and no filler.

The weakest part of a hollow metal door is often the seam. – FACT. The seam of the door is where it all comes together or all falls apart. Mesker's NVS door turns the weakest part of the door into a bastion of strength. So strong that it comes with a lifetime structural weld warranty.

A stitch-welded door, with bondo, is just a good as a fully welded door – FICTION. In a stitch-welded seamless door, temperature changes and constant use eventually cause the putty to crack and break out. The result is an undesirable appearance. In a fully welded seamless door, with no bondo, like the NVS door, you get strength, quality, and beauty that won't crack or change over time. We guarantee it with our lifetime structural weld warranty.
