The design concept of our office desk is simple and modern representing the esthetic value in the office. In order to enrich more intellectual and creative atmosphere in the office we adopted slim rectangular shape of the steel pipe in the design. We have designed the special joint (pipe frame structure of non-welding type three direction assembly system) which connects legs, side connecting parts and supporters together. Our office desk keeps preventing any movement and shaking in all directions. We are proud that we have realized the economic efficiency together with optimum materials at the lowest cost.
