Lindab Company is one of the leading suppliers of steel shop floors technological solutions. The Company operates in a network of incorporated building companies called Lindab Builder.
JOKA Company offers professional construction of steel shop floors as Lindab Builder
We meet high standards of Lindab Builder Systems in system steel structures. We are able to construct any plant in Turn Key technology or in the part agreed upon with the principal.
Technical solutions offered by Lindab Builder Systems are characterized by using the steel plate girder systems in the steel shop floors structures.
Advantages of the plate girder system over the truss system:
- Higher resistance to fire as the profiles used in plate girders are of bigger mass (the trusses usually use thin-wall profiles), for the reason of truss system structure an increase of the resistance properties is extremely expensive or even impossible,
- More freedom in equipping the interiors of the plant (bigger space in the roof ridge area, no difficulties in leading the installations hung up to the roof),
- In the trusses there are lots of places attracting dusts and impurities so there are many more potential corrosion centers,
- The trusses are more difficult to carry out maintenance works of the structure itself and installations, units hung up to the roof.
- Bigger usable area in comparison to the truss system.
Lindab offers shop floor structures in the systems:
- Lindab Widespan – large steel shop floors
- Lindab SystemLine – medium-size steel shop floors
- Lindab SBS – small building system
LINDAB Widespan BUILDING SYSTEM
Is versatile and economical. Using the gantry frames is an economical solution that enables much freedom in design.
Widespan System allows optimum internal space usage and is suitable for production plants, warehouses, logistic centers, recreational buildings and shopping centers. The standard single bay frames span is 12 – 42 m. Significantly bigger spans are also available.
Standard multi bay frames are available within the span of 24 – 90 m.
Widespan SYSTEM CHARACTERISTICS:
- Plate girder primary structure made of improved plasticity limits steel and higher resistance to corrosion has the system of purlins tightening in order to stabilize and protecting the purlins from buckling in the roof surface. This system assures the stability of the building and inline setting of purlins rows for suitable mounting of internal roof plates and the system liquidating the heat leakage bridge;
- The wall spandrel beams equipped with the system protecting from hanging down;
- The bridge system – the solution of the roof structure that thoroughly removes the line heat leakage bridges and which protects the building from significant glass wool compression and the effect of “settlement” of the insulation layer;
- The solution of the roof structure that enables free movement of external sheets caused by the thermal expansion to avoid the effect of “tearing off” the connectors;
- External paint-coated galvanized TORX-headed bolts in the color of wall plates used for mounting the sheets to the spandrel beams;
Widespan system allows building bigger shop floors:
- Single bay,
- Multi bay,
- Multi bay with ridge roof,
- Multi bay with wagon roof,
- Single bay with lean-to roof,
Each of the aforementioned types of buildings can be extended by an outhouse, whose roof is an elongation of the hipped roof end or is lowered in comparison with the main building roof and indirect ceiling. The Widespan system shop floors allows designing a support structure for gantry crane.
The secondary structure are the hipped roof ends as well as spandrel beams made of “Z” type of cold bended galvanized components. The hipped roof ends work as the multispan beams. The hipped roof ends span amounts to 1.5 m.
The standard wall spandrel beams are 165 or 250 mm high – they operate as the single span beams. The first spandrel beam is mounted at the height of 2.25 m, and then the other ones at every 1.5 m.
In order to limit the consumption of steel the belt bracing of the internal spandrel beams and frame supports are used. The braces are adequately mounted to the hipped roof ends or walls spandrel beams.
The standard brace method of a structure is to use the crossed bar braces. If this method is impossible to apply, gantry frames are used, which considerably raise the structure mass.
The structure solution which is used most often for the purpose of building the shop floors is the single bay shop floor with the lean-to roof (LRF). While following such a solution it is recommendable to use the span of 20÷30 m, at the height in the eaves of 4÷7 m and the frame span of 7÷9 m.
For buildings of over 42 m span with no indirect supports it is required to use additional brace system which increases still huge steel consumption. Referring to these for bigger spans it is more advantageous to use multi bay shop floors of MRF type, which brings about the reduction of the structure mass by a few dozens of percent. The most economical solutions can be obtained with bays of about 15÷20 m span and the height of 4÷7 m.

LINDAB SYSTEMLINE BUILDINGS
Systemline building system was designed for the span of about 25 m, particularly in the case of big angle roofs. It is characterized by frequent use of hot-rolled profiles in buildings.
Lindab Systemline System allows fast and easy assembly. It is suitable for production plants, shopping centers and buildings for farming purposes.
The building designs used most often are:
- Single bay shop floor with a ridge roof or lean-to roof with supports mounted with joints in the foundation,
- Double bay shop floor with the ridge roof with supports mounted with joints in the foundation.
In certain cases the supports can be mounted firmly in the foundation.
In each of these solutions any outhouse or entresol is possible to add.
As a secondary structure components the hipped roof ends and spandrel beams of “Z” type cold bended galvanized components are used. Both hipped roof ends and spandrel beams work as multispan beams tightened over the supports by an overlap. Maximum span amounts to 1.2 m.
The standard wall spandrel beams are 150 mm high and the spandrel beams are 200 mm.
The standard brace method of a structure uses the crossed bar braces. If this method is impossible to apply, gantry frames are used.
The most economical span of frames is to 7÷8 m at the height of about 5÷6 m and roof angle of 6 degrees for a double bay shop floor.
