The traditional SkanDek elements with 200/300/350 mm box beams can be used as floor slabs and roof structures without significant u-value requirements.
SkanDek floor features are uniquely suited when light load-bearing structures used, or where other circumstances require the minimal weight of an intermediate floor. SkanDek is particularly suitable if a developer wants floors of an existing building (refurbishment). With Skandek radiant floor slabs construction of about 65-120 kg/m2, it will often be possible to use the existing foundations.
The patented SkanDek beams can be produced in three heights 200, 300, 350 mm with a maximum span of 22 meters.
The beams are carried out in two different wall thicknesses 1.5 mm and 2.0 mm.
The designation is made in such a way that the first two digits indicate the beam height in cm, and the second number indicates the wall thickness.
SD352; SD is short for SkanDek.
SD352; 35 cm high.
SD352; 2 mm gauge. 1= 1,50 mm gauge.
The combination of three heights and two gauges makes six variants; SD201, SD202, SD301, SD302, SD351, and SD352.
The beams made of two profiled U-channels with spaced bulkheads for stiffening inside.
The beams can be done with a camber/crowning up to 300 mm.

Primarely used when U-values from 0,15 to 0,06 W/m2K are needed.
Product Description – SkanDek Green Line
SkanDek Green Line is leading the U-value of prefabricated elements with U-values down to 0.08 W / m2K supplied from the factory.
SkanDek Green Line mainly used for roofs constructions and roof terraces.
The key element of SkanDek Green Line is the patented lattice beams, which is an evolution of the traditional SkanDek box beam.
Grid bars produced in four heights – 450, 500, 550 and 600 mm, with a thickness of 2.0 mm.
The designation made so that the number in the name indicates the beam height.
SD550: SD stands for SkanDek
SD550: 550 mm grid beam.
Grid beams consist of two first profiled shells, – a top and a sub-dish to be joined using a grid system – so-called Delta braces.
Reaction: The individual response capacity = 34.9 kN, which means consequence class gives a calculated response to 31.73 kN per. beam.
Moment: The specific final moment is from 100.5 kNm to 146.7 kNm per. Beam, depending on the type. That is an enormous strength about weight, which ranges from 19 kg per. Meter to 24 kg each running meter.
The strength of the grid beams are also significantly increased compared to the traditional box beams. Comparing a grid beam type SD600 with a box beam type SD200 will grid beam more than five times as strong.
That is of particular importance in the large spans of 18 m, where the number of support beams significantly reduced by using SkanDek Green Line.
The increased strength means at the same time a significantly improved stiffness, which means that it is not necessary to produce elements with significant camber heights.

Many different combinations.
SkanDek Green Line is available with several types of finished and semi-finished roof and ceiling linings.
