Other types of hall buildings are hangars, car halls or agriculturally related buildings. Examples on industrial buildings are power plants, processing industries and other types of buildings for heavy industrial production.
For all buildings where large span is an important parameter the steel hall is the main alternative. It is also quickly erected according to well developed system solutions and easily treated and mounted components.
There are a several companies specialised on constructing steel halls in different sizes, shapes and types. Some of the companies have own developed framing solutions and efficient organisations giving low costs and high quality solutions.
The steel industrial building can be built in many many ways. The basis is though a steel frame adapted to the processing equipment and activity that the building will cover. The façades and roof are often build with steel sheet. Today power plants are built relatively close to populated areas, and with aesthetical and environmental demands taken into consideration.
The basic principle for halls and commercial buildings is a system based on steel columns, steel beams and steel plate rafters. The columns are often rolled HEA or IPE profiles with top and foot plates. Welded columns can be used in large halls with heavy overhead travelling cranes. The columns are normally mounted with four encased anchor bolts.
The rafters often span over the entire width of the hall, but the hall can also be divided into several bays with intermediate column rows. Often the span is so large that you choose trusses or high welded I girders as rafters.
Roof and façades are normally covered with steel sheets. The exterior wall can be constructed from a light post frame (often horizontal webs fastened directly to the steel columns), insulation and a profiled (trapezoidal) plate or plane cassette as façade materials. It can also be built from pre-fabricated steel plate and rockwool insulation sandwich elements.
The roof is carried up by profiled steel sheeting, fastened directly to the roof girders or to secondary purlins between the roof girders. On the sheet a plastic foil is put, and then a heat insulation layer and finally the covering steel layer.
