Hi,

The handrail and various connectors between the rectangular panels are in MS square sections welded to each other.

The rectangles may be made in a variety of materials as listed below -

1] HDF with duco paint finish

2] MS plate welded onto the MS framework

3] Ply finished with laminate

4] Acrylic panels

5] Aluminium Composite Panels

First the framework of MS sections is made with the panels secured on it from both sides. Next the handrail is added from the inside face of the panel.

That will depend on where you fond this image. If you found it on Houzz, look for more images from the same project.
