The sun is the source of all energy. However, not all its energies are good for us. The ultra violet rays are in fact downright harmful to life on earth. If you want to lead a healthy and full life, protect yourself from it at all cost. Earlier, it was not that essential; but now, with excessive carbon emission taking place all the time, the atmospheric layers that earlier provided the protection are steadily being destroyed. That is why we need to get added protection in the form of patio umbrellas if we want to spend considerably longer period under the sun.
However, buying a suitable umbrella is not easy. There is such a wide variety that unless you make intelligent and conscious choice, you may have reason to repent. Therefore, decide on the following first and then proceed:
• Do you want it for your private patio or for commercial space? If it is the later, always opt for commercial patio umbrellas.
• What do you want to cover with such umbrellas? Do you have bistro tables with holes in mind? Then, get a market umbrella. On the contrary, if you have chaise loungers at poolside or simply a conversational set on the deck in mind, you may find the offset umbrellas to be more suitable.
• Now, how big the area to be covered is? The shade length should be at least four to five feet greater.
• What type of weather condition do you generally have in your area? The umbrella material will depend on that.
Now, the commercial patio umbrellas are quite elegant to look at, but they are made more with public safety on mind than with ease of operation. Indeed, if need be, convenience is always sacrificed to make them safe for use in high traffic area. For example, these umbrellas have solid poles made out of single piece. This may make transportation and storage more difficult; but because solid poles without couplings make the patio umbrellas sturdier and less prone to breakage, the commercial ones are made that way.
Then again, pulleys, cranks, tilt mechanisms, which make the operation easier and the use more convenient, are all absent in commercial patio umbrellas because of that reason only. Another important feature is that these umbrellas generally have their rib arms made from fiberglass. You see, if you suddenly have a strong wind blowing, the rib arms will have to withstand the maximum impact. Rib arms made from aluminium or wood tend to fight such gusts and so snap faster; the fiberglass rib arms on the other hand just absorbs the gust and so they last longer.
Therefore, even if you buy an aluminum or wood umbrella, make sure that if you use it for commercial purpose, the rib arms are all made out of fiberglass. Although it is always advisable to close the umbrella when a storm is in the offing, it may not be possible to do in a commercial space. That is why it is always important to have the pole made out of solid piece and the rib arms out of fiberglass.
In general, both aluminum and wood are suitable material for umbrella making. As it is aluminum is a very sturdy metal and the wood umbrellas are made out of Asian hardwood; so both these umbrellas last quite long. However, aluminum has one advantage that wood does not have; that is, aluminum can be easily machined and so such umbrellas can have better finish. In fact, an offset umbrella will always be made out of aluminum, never out of wood. The market umbrellas on the other hand can be made out of every type of materials.
Buy a wood umbrella if your setting is traditional. Nothing can match them in their quaint grace and unobtrusive beauty. The aluminium umbrellas, both offset and market, are more suitable for contemporary setting. However, if your patio table does not have any hole or if you need uninterrupted shade, the sidepost offset umbrella will suit your more.
However, the best advantage of an offset umbrella is that it can be rotated full three hundred sixty degree and so you can relax under it all day long without having to shift space. In fact, this is the very reason, why clubs and resorts prefer them to ordinary market umbrella with poles coming down from the centre of the frame. However, for your commercial space, do look for commercial offset umbrella only. As I said, commercial umbrellas are made sturdier so that public safety is never compromised.
