BEAMS

Beams are used as downstand beams, foundation beams and roof purlins.
Rectangular – slabs are based on the upper surface of the beam, gives a relatively large ceiling height, therefore  sometimes it is necessary to use cross section view inverted “T” or “L”.
“T-bar” – inverted T beam, mainly produced as downstand beams where the floor is based on a linear bracket at the bottom of the beam.
„L” – as floor edge beams, ceiling is sitting on a linear bracket at the bottom of the beam.
Trapezoidal – mainly used as prestressed concrete purlins
