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 for mast replacement. A special drainage system and markings on the masts minimize the risk of damage, and if necessary, the manufacturer covers the costs of replacing damaged segments. AluPro ensures not only durability, but also safe installation.

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.…

Bolt Classes – how to understand them and why are they important?
Read more: Bolt Classes – how to understand them and why are they important?In the mast industry, the standard are flange connections depending on the class of bolts, which determine their tensile strength and ductility. The classification of screws, described with 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 the building structure – what should I know?Customers often wonder why the mast mount is more expensive than the mast itself. The values of the pulling and driving forces in the roof quoted in the static calculations show how important proper anchoring is, which often requires serious construction works and specialized solutions, individually tailored to each building.

How do you safely install antennas on a mast?
Read more: How can I safely install antennas on a mast?A telecommunications tower, like any truss, has node points that are its strongest areas. It is best to apply any forces in the vicinity of these points, as this minimizes the risk of localized damage to the structure. This is important in practice when installing additional guy wires, securing ropes during the rotational erection of a tower, and when selecting anchor points for antenna booms. A node is a point…

How does the aluminum welding technique affect the weld strength?
Read more: How does the aluminum welding technique affect the weld strength?The quality of the weld is crucial to the safety of the product. At AluPro, we weld aluminum exclusively using the TIG method, with Fronius and Kemppi machines. TIG welding is a slow process, but it guarantees deep penetration and full control over the quality of the weld. This method produces very clean and aesthetically pleasing joints—which is particularly important for components that require both strength,…
