Cooperation with SpaceForest
Read more: Cooperation with SpaceForestIn 2019, we established an interesting cooperation with the then emerging company SpaceForest. Based on their internal design, we made - in accordance with our specialty - the truss of the Perun rocket launcher. Made to "space" standards, the truss was created from a special grade of hardened AW6082 aluminum and extra-thick tubes for high stiffness at the crucial moment of highest load at launch. An interesting feature...

Assembly for chemical anchors - description of the technique
Read more: Assembly for chemical anchors - description of the technique.Most of our wall masts are installed using chemical anchors and threaded rods. This is a very convenient and robust technique, nevertheless vulnerable to execution errors. The reactions on the pins especially in the case of taller and more heavily loaded masts reach values counted in tons, so the quality of the fixing is crucial. General note - if you are not a professional installer or...

How to avoid frost cracks and their consequences?
Read more: How to avoid frost cracks and their consequences?AluPro masts offer a lifetime warranty against frost cracking, a problem that often leads to the need to replace the mast. A special drainage system and markings on the masts minimize the risk of damage, and if necessary, the manufacturer covers the cost of replacing damaged segments. AluPro ensures not only durability, but also safe installation.

Optimization of the height of masts for the radio link.
Read more: Optimization of the height of masts for the radio link.Designing a radio link network requires ensuring visibility between antennas and the presence of an unobstructed Fresnel zone. Altitude maps, drones and meteorological balloons are used for field verification. The price of the service is PLN 3,200 net per day.

Stainless Steel – What Types?
Read more: Stainless Steel – What Types?Some of our structures receive stainless steel fittings for an additional fee. Have you ever wondered what this means in practice? Well, commercially we distinguish 2 "levels" of stainless steel. Here's how it should be understood (quoted from the marmech.eu portal) Stainless steel - this is a common term for a group of corrosion-resistant steels, in a little more detail we can divide them into corrosion-resistant steels...

Screw Classes – how to understand them and why are they important?
Read more: Screw Classes – how to understand them and why are they important?In the mast industry, the standard is flange connections dependent on the bolt class, which determines their tensile strength and ductility. The bolt classification, described by two-digit symbols, informs about their maximum load in relation to the cross-section.

Reactions to building structure – what should I know?
Read more: Reactions to building construction – what should I know?Customers often wonder why the mast attachment is more expensive than the mast itself. The values of the tearing and driving forces in the roof quoted in the static calculations show how important proper anchoring is, which often requires major construction work and specialist solutions, individually adapted to each building.

Anti-fall system – what is it and how does it work?
Read more: Anti-fall system – what is it and how does it work?Working on towers and masts can be dangerous. This is evident from the manufacturers' recommendations suggesting that work on structures should not be carried out in winds above 5 m/s. Fortunately, we have access to BHP or mountaineering harnesses, which significantly increase safety, although rarely comfort. Changing positions on a mast is particularly uncomfortable, when each step means having to re-buckle the reins……

I am putting a mast/tower on the ground – how should I foundation it?
Read more: I am putting a mast/tower on the ground – how should I foundation it?The rule is that the foundation should not reach below the groundwater level. If the water is shallow or very shallow – then a foundation slab weighted with an earthen embankment is most often used (or shallowly buried “mushrooms”, i.e. prefabricated foundations of the F series, e.g. manufactured by Elbud Gdańsk). Cast slabs are also often used when just below the ground surface in areas…

How to safely lightning a mast? Basic knowledge.
Read more: How to safely lightning a mast? Basic knowledge.There are three main issues in the case of lightning protection of telecommunications masts that must be taken into account. In our opinion, the best and cheapest way to discharge the electric charge is through the structure of the mast or lattice tower. Alupro solutions are equipped with a special eyelet in the lowest segment that allows the whole thing to be connected to the building's lightning protection system. In the case of painted structures, remember to remove the coating…
