Regardless of if you have a rental unit, or if you have a custom trade show display produced your needs are going to be dependent on the type of exhibition. You don't want a drastically different booth that is unrelated to all of the other trade show booths, but you also don't want to be too much like all the rest and go unnoticed.
There are a few different types of trade show displays. Some common types of trade show booths include pop up or pull up displays, ones that are table top based, panel displays, and truss displays. Pop up displays are renowned for being light weight and can be used to make walls for trade show displays.
A panel display is a fabric covered section that gets connected to make a wall. A distinct advantage to a panel display is that is can be readily turned into a trade show display wall. Truss displays are made of lightweight tubing, typically of aluminum. These are a little more futuristic in appearance because they can be made into a variety of shapes and sizes. Table top displays are less expensive but you sacrifice by saving price. This is because more often than not these are not the most elaborate of displays and make it look as though you were trying to save money.
Often times you can get a company to make a display for you that is unique and stands out from all the rest. Choosing the right company to make a display for you is dependent on a few variables. You should try to find a company that specializes in the types of displays you are looking for. You do not necessarily have to get a company that is in the same field, but just one that can meet your knees.
A great way to find a good company is to talk to other exhibitors that are not in competition with you. This is because they will give you unbiased information on who they have found to be best insofar as supplying goes. Be wary about talking to anyone that you are in direct competition with because you cannot always trust their advice, especially if they're trying to produce a trade show exhibit that is in direct competition with yours. As long as you do your research and think like your potential customers you will not be disappointed with the results you get.
