Features of Portable Banner Stands

As simple as they are, there are important differences in banner stand construction you should be aware of. Here are a few important features to pay attention to while constructing your banner stand.

Field Changeable Graphics

This means you can have different versions or messages for the same hardware unit and change banners anywhere, anytime, in minutes. Change them out, change them back. Great for keeping a whole sales force up to date without the expense of new hardware. Alternate graphics ship and store in cardboard tubes. Because this feature adds so much flexibility to your banner purchase, BenchmarkImaging carries 3 units that support this flexibility: ExpoPro, SUV Plus and E-plus.

The base

Base depth and weight dictate the stability of the banner stand. Less expensive stands answer this need with feet that rotate out. Lighter weight units, although easier to transport, fall over easier as they become heavy at the top. Best designs use a 10 lbs wide base with a low profile (low center of gravity). For outdoor use, where wind is a possibility you can use outdoor banners. Last, some floors are uneven or pitched instead of flat.

The pole

In order to pack conveniently, banner stand poles have to break down into pieces. Many units add an elastic shock cord to make the set up easier. But this also means you can only have one height for your graphic. If you want the flexibility of using your roll up banner as a tabletop unit, a shock-corded pole can prevent it. Cutting the cord may work but then the attachment to the top rail or base can become an issue.

Pole attachment to the base

Some retractable banner stands require the pole to screw on to the base. This is a real disadvantage for quick portable setups. None of our units assemble in this manner.

Graphic attachment to the top rail

This is important because if the attachment fails, the banner graphic will roll up into the base and loose all spring tension. After this happens, some units can be repaired but it probably won't happen until your show is over. Cheaper units use a single layer of double-sided tape for attachment. Better units employ mechanical clamping or adhesive envelopes to insure against having the problem.

Graphic attachment at the pole top

Some units use a hook to attach the top rail to the pole. This leaves the top of the pole sticking out above your graphic and lowers the aesthetic value of trade show displays.

Bags & Cases

Bags for the more expensive units look smarter and include extra padding to help protect your investment. None of the bags are safe for common carrier shipments. If your plan calls for shipping your display ahead, you should consider a banner stand with a "Hard Case".

Science geniuses out there?

Experiment: Finding out how much energy 1g of different foods have.
Basically, the question is how can you improve the apparatus?

The basic flaw with such an experiment is that it takes different amounts of calories to release the flammable components from different foodstuffs, to heat the water, so any result is rendered irrelevant.

I got into all sorts of trouble at school, when I pointed this out to my "Stinks" master........... fortunately, he was amenable to argument and I won the term prize for chemistry on the back of it.

To make the experiment valid, the flammable products should be stored, to cool, after the first heating has released them. The experiment can then be conducted with an accurate outcome.

Weigh the reduced components, due to the first heating cycle, before using them to heat the water.

Do not forget there will be a gaseous component, which may or may not be flammable. That means you need a pressurised oxygenating input, to support combustion, and a low pressure output, to release the heated gases after combustion. The water heating process has to be conducted in a partially sealed chamber.......... which I leave you to devise........
