Raudbetoontalade ja pingebetoontalade mõõdud ja kujud

We manufacture precast concrete beams with the following cross-sections:

Beams with rectangular cross-section
width 3M, 4M, 5M, 6M, 7M
height 5M, 6M, 7M, 8M, 9M, 10M, 11M, 12M
Modular measurement M is 100 mm. In the case of different dimensions, the conditions for manufacturing the beams must be specified.
Recommended cross-section dimensions are 400x600, 400x700, and 400x800.

Ledge beams
width 3M, 4M, 5M, 6M, 7M
height 5M, 6M, 7M, 8M, 9M, 10M, 11M, 12M

Low height prestressed beams (see also TEMPO substructure ET-3 0202-0073)
width 550, 650 (1-ledge beam width in the lower surface)
700, 800 (2-ledge beam width in the lower surface)
height 415 (EP5/265), 470 (EP4/320), 550 (EP4/400)
Ledge height 150 mm

I beams
flange width 3M, 4M, 5M

I beams load diagram:

HI beams ( I beams with ridge)
flange pitch 1:16
flange width 3M, 4M, 5M
The corners of the mould are 15x15 mm
