The artist painted sheets of paper probably with an airbrush then inlaid these cylinders using a scalpel or cutter then applied red colored strips laminated.
These sheets of paper were glued on isorel panels then was set with black plastic (see the last photo).

The style is between neo-surrealism, kinetic art, reminds me of certain achievements of Julio Le Parc (born in 1928) from the early 1990s.
Simply put fasteners on the back to install them on the wall.
Each panel measures 111.5 cm x 76.5 cm.
In total if they touch, the quadriptych measures 223 cm x 153 cm.
