When it comes to banners, it’s rarely about the print and almost always about two other things: how much wind needs to pass through them, and how the fabric is secured. Those two factors determine which material you need.
The standard fabric is a 500-gram frontlit fabric, tightly woven and with eyelets for tensioning. If the fabric is to cover an entire façade or the top of a building, then it is a XL cloth in one piece. And if nothing behind it can be seen through either side, then there is 620-gram blockout, which can display a different image on each side.
If the fabric is left to flutter freely in the wind, against a fence or on a frame, a solid fabric becomes a sail. In that case, you should choose mesh, which allows the wind to pass through and therefore holds its shape where a solid fabric would tear. For a scaffolding That is not a choice but a condition.
For construction site hoardings and events, there are standard sizes, as the fencing itself comes in set sizes. You therefore do not need to measure out a Heras banner or a crowd control barrier banner. Everything here is hemmed, with eyelets every 20 to 50 centimetres or according to your own specifications, or with a tunnel hem through which a tube is threaded.
