But if you still need to make a big display but with limit budget, and the branding needs the full printing. Then we can also make you an suggestions.
Factors to affect the weight resistance per shelf:
For example, design A is 500mm wide x 235mm deep. If the size is 300mm x 235, the weight resistance is stronger than 500mm x 235mm.
2. Structure of the design model
For design B, we can enhance the weight resistance per shelf by adding 1 or 2 metal bars. But Design A cannot do this.
Factors to affect the stability :
1. Size about the depth
For example: design A is 500mm wide x 235mm, if the depth is 350mm, it is more stable.
2. structure of design
For example: Design A is light weight, and Design B is heavier with more maerial used.
If the base is taller, the bottom will support more. It is about center of gravity.
If the design A lean against the wall, the more stabiliy is no doube.
Suggestion for Design A:
If the display does not lean against the wall, the size is advised to change.
Such as: 400mm wide x 300mm deep x 1500mm Tall
And the material can be 5mm thick
If so, the cost will be increased as well
