Hi, I am looking for a manufacturer which can able to fabricate a specific design board. This board can be folded into a compact size and easy to be carried around. Compact dimension: ard A3 size. When opened up, it can formed at a length of 4 A3 size length by 2 A4 size width. Thickness at least: 1 1/2 inch thick. Materials can be wood or steel, depends on the durability and MUST be light.

Will be using this item to form a bridge over something that I can cross over for my latest project.

Thanks in advance.
