Make a door head with light box cloth (that is, the signboard of the storefront room), and then have a steel frame structure with a thickness of about 20CM, and paint the surface to light the signboard. how much is it? The thickness of light box cloth and square pipe frame is about 100/ m2 (easy to install).

If the labor cost is expensive, the installation depends on whether the site is good or not (are there any stairs with air conditioning on several floors in the way)

What kind of spotlights are used to illuminate the top? Add a few ordinary wires and iron pipes of about 20 (well, there are hundreds).

If there are lights inside, plus lights, there are generally three light wires in one square meter, and some accessories are counted separately.

That's about it. If there is no thickness, it will be cheaper to save a flat film and 20 cm.

The market varies from place to place.
