A steel-profile hall at the Volos plant of the Heracles Cement company belonging to the Lafarge group, which covers the raw materials of additives for cement production.

A project necessary for the storage of about 40000 tons of additives, as well as the protection of the environment from dust.

The steel-profile hall comprises a total of 11 steel-profile frames, 10.35 meters apart, with a total length of 130.5 meters.

Each frame features a 50-meter span and a 22-meter height and has cross-sections of variable statics height and of variable web and flanges thickness and length, pre-fabricated in the steel-profile factory.

The frame is distinguished by its minimum and optimal weight and its slenderness.

The steel-profile frames are based on reinforced concrete columns, which are connected to each other with a peripheral reinforced concrete wall 3.5 meters high.

The construction comprises two types of foundation: on the one side the building is based on individual flat foundations and on the other side it rests on micro-piles, due to the extremely soft soil from debris deposits.

The rail on which the stacker and the reclaimer move is also on the soft soil side and is founded on micro-piles too, to avoid differential settlements.

The stiffening of the steel-profile construction on the beam inclined levels of the frames was achieved by the use of trusses between the purlins.

The erection of the building was relatively easy, due to the low weight of its components, their simple arrangement layouts and the absence of in-situ welding.

Detailed checks on the quality of the welds were carried out at the factory.

The erection was done with absolute security, in a short time and the result was highly qualitative.
