I'm starting a mast-building project—what do you need to know to help me?
Read more: I'm starting a mast-building project—what do you need to know to help me?The construction of telecommunications towers and masts is a highly specialized field. In Poland, only a dozen or so companies carry out this work independently, while several dozen others operate by subcontracting to the actual manufacturers. Due to the narrow scope of specialization, most designers, architects, and civil engineers do not have extensive experience with this type of project. This post aims to clearly and concisely present…

Stainless steel – What grades?
Read more: Stainless steel – What grades?Some of our structures can be equipped with stainless steel fittings for an additional fee. Have you ever wondered what this means in practice? Commercially, we distinguish between two “levels” of stainless steel. Here’s how to understand them (based on the marmech.eu website). Stainless steel—a general term for a group of corrosion-resistant steels. More specifically, we can divide them into corrosion-resistant steels and acid-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.

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 general rule is that a foundation should not extend below the groundwater level. If the groundwater table is shallow, the most common solution is a foundation slab weighted down with earth fill or shallowly buried precast elements (so-called “mushrooms” from the F series, e.g., those manufactured by Elbud Gdańsk). Cast-in-place slabs are also used in mountainous areas, where just below the ground surface there are…

How to remove lightning from a mast safely? Basic knowledge.
Read more: How to remove lightning from a mast safely? Basic knowledge.When installing lightning protection for telecommunications masts, three main issues must be taken into account. In our opinion, the best and most cost-effective way to dissipate the electrical charge is through the structure of the mast or lattice tower itself. AluPro products are equipped with a special eyelet in the lowest segment, which allows the entire structure to be connected to the building’s lightning protection system. For painted structures, be sure to remove…

Do I have to paint my mast with red and white stripes?
Read more: Do I have to paint my mast with red and white stripes?Regardless of the mast’s location (on the ground or on a building), structures under 50 meters in height do not require notification to the competent military aviation oversight authority (for civil aviation, this threshold is 100 meters). The legal basis is the Regulation of the Minister of Infrastructure of June 25, 2003, on the procedure for reporting and marking aviation obstacles (Journal of Laws No. 130, item …

In my area, the District Office expects PnB in relation to the mast on the building – is it right?
Read more: In my area, the District Office expects PnB in relation to the mast on the building – is it right?There is much to suggest that this is not the case. Judgment II SA/Gd 329/14, issued by the Provincial Administrative Court in Gdańsk, is currently in force. In the reasoning for the appellate judgment in this case (i.e., a building permit for a mast on a building), the Court cited Article 29(2)(15) of the Construction Law, as well as Article 30(…
