Poles and stakes
Aluminum is a great metal. It is lightweight, strong and durable, hence a good choice for use on hikes off the beaten track. It is our choice of metal for use in poles and stakes in all our tent models. It reacts little to other substances, but aluminum in its purest form reacts very readily with the oxygen in the air. Therefore it is also rare to find pure aluminum in nature. However. This is also an advantage with manufactured aluminum as the surface of the aluminum reacts readily with oxygen and forms a protective film on the surface of the metal so that the metal does not react further with the air. Aluminum in its purest form is not a strong metal.But by adding other metals to the mix, such as magnesium, copper and zinc, its characteristics can be adjusted to fit the desired purpose
It is this alloy that determines, for example, whether your aluminum stake or tent poles should be strong, flexible, rigid, etc. Properties that vary in terms of what it should be used for. A center pole in our Lavvo should contain other characteristics than, for example, the tent stakes. The center pole of the Lavvo should be somewhat flexible so it can withstand being slightly bent (without breaking, of course). This is an important feature of the center pole as it is subjected to great forces and energy that tries to bend it. Same goes for the poles on Gamme series and Vern series as well.. These poles should be even more flexible. We want some of the energy from the wind to actually bend the poles slightly instead of cracking it.
If we for example were to use the same aluminum alloy in the poles as in the tent stakes, the poles would have been very rigid and sooner or later cracked as a result of the movement it is constantly subjected to. Especially when the tent is exposed to a lot of wind. The stakes, on the other hand, should contain an aluminum alloy that makes the stake a lot rigid but at the same time strong where the plug must withstand bending to a certain extent without breaking. The tent stakes are, as you know, mostly planted in the soil without any movement and do not need the same flexibility as for example a tent pole.
That is why we use different aluminum alloys for different applications. For our aluminium poles and pegs, we use the industry's strongest aluminum alloy of the 7000 series where the aluminum is mixed with zinc, magnesium, and copper.But the ratio between these are depending on if it is a pole, peg, etc. A pole needs to be very flexible where it is able to bend quite a bit without breaking. So both the pegs and poles are carefully designed and manufactured based on what we think is necessary and appropriate for real adventures.
Although carbon poles are marginally stronger and lighter than aluminum, they are not as flexible. If they are bent, the carbon pole breaks a lot quicker. For the "lightweightjunkie" we do of course offer carbon poles Because we want this to be your choice. But in general we actually recommend aluminum as aluminum is a very flexible alloy which can better be adapted to the different and special uses
