OÜ TMB Element manufactures ribbed slabs with pre-stressed reinforcement (product name TT-slabs).
The TT-slabs are produced by using pre-stressed longitudinal reinforcement in the tensile zone and, if necessary, also in the compressive zone of the slab.
The TT-slab consists of an upper board and two longitudinal ribs. The standard width of the TT-slab is 3,000 mm, height is between 400 – 1,000 mm with a spacing of 100 mm, the length is up to 24 m and weight is up to 30 tons.
The width of the rib is selected according to the bearing capacity and fire resistance requirements. The standard widths of the ribs are 140, 160, 180, 240 and 300 mm.
