Towers

Design

We can refer to global experience as our antenna towers are supplied worldwide in use for telecommunication. By using advanced computer programs every tower is calculated and designed to fit the client’s specification. In addition to the towers, we offer a full range of accessories – including grounding, antenna mounts, aviation warning lights, paint, fences and more.

GSM Towers design the tower foundation and provide optimum exploitation of foundation mass based on soil data. We offer both single footing and raft foundation design. Our foundation design is specifically designed to decrease installation- and rollout time, as well as minimizing the foundation volumes needed.

Production

GSM Towers has a network of complete sets of production facilities to ensure large production capability. It includes both automatic and semi-automatic angle steel lines, and tubular production lines. We use a network of manufacturing plants that meet the high standards set by GSM. All our vendors are ISO 9001 and ISO 14000 certified. GSM are involved on every factory, and have inspectors on site who conduct test assembly and monitors packaging and loading at the factories.

Manufactured towers are packed according to GSM Towers SMART pack system. Loads are packed on site-by-site basis and in small bundles – to withstand rough transport handling. Smaller parts are secured and packed in steel cages. We also apply color coding to ensure easy identification of loads when arriving at site. To ensure that all necessary information is available on time and minimize time consumption till site is on air, GSM Towers provide a detailed packing list for every tower model, and a color coding scheme for each container.

Self Support Tower

GSM Telecom Products offers four main types of Self-Supporting Towers; Angular, Tubular, Monopoles and Hybrid Towers. Hybrid towers usually consist of tubular main legs with angular bracings. Our Self-Supporting Towers are suitable for practically all communication applications, however most ideal for rural areas where space requirements are limited. We produce both 3- and 4-legged towers and anything from 15m to 150m.

All our tower types are hot-dip galvanized after fabrication to guarantee years of corrosion-free use. And all designs are according to EIA/TIA-222 specifications. For angular parts we focus on high quality where we use 3 main steel qualities; Q420, Q345 and Q235. All angular parts are cut and hole-punched by computer programmed machines in order to minimize differences in steel parts.Our tubular parts are welded by professional welders to ensure highest quality possible.

Guyed Masts

Opposed to Self-Support Towers, Guyed Masts generally needs more space, however the steel structure itself is usually thinner, therefore lighter and also quite often taller than Self-Support Towers.

The Guyed Mast itself has the compressive strength to support its own weight, however, typically does not have the shear strength to stand unsupported, and needs guy lines, diagonal tensioned cables attached to the ground, usually spread out at equal angles about its base, to resist lateral forces such as wind loads and keep it upright.

Our guy lines are of highest quality, either from China or if requested we have partners in Sweden for the highest European standard guy lines.

Roof Tops

Rooftop towers are usually installed in dense populated areas and where tall buildings can handle antenna weights. The rooftops requires greatly less space than both Self-Support Towers and especially Guyed Masts. Although rooftops can be installed with guyed masts, they are normally from 2m up to 15m of height.

Our Rooftops are also like the other type of towers custom designed to ensure the clients requirements. The rooftops are mostly designed with angular steel basis structure and high quality guy lines, or self-supporting tubes.

The Rooftops can be casted into cement or they can be build straight on the roof of a building on just a steel structure that holds the rooftop perfectly still.
