3. Product range and designation

Standard girders consist of selected webs and steel plate flanges with identical dimensions for the upper flange (OG) and lower flange (UG).

Web dimensions:

Web heights:	500, 625, 750, 1 000, 1 250, 1 500 mm
Web thickness:	2.0; 2.5; 3.0 mm

Flanges:

min. w = 200 mm	max. w = 430 mm
min. t = 10 mm	max. t = 30 mm

Lengths supplied:

min. 6,000 mm , surcharge for short lengths
max. 20,000 mm

Maximum dimensions for construction elements:

See construction details, Sheets 1.3 and 1.4 (Appendix C).

Designation of girders:

WTB 1000 - 300 x 15
15.. 300.. 1000.. WTB..	flange thickness in mm flange width in mm web height in mm key for web thickness ...	A ..... 2 mm
		B ..... 2,5 mm C ..... 3 mm

Special structural forms with any intermediate heights and/or different sized upper flange (OG) and lower flange (UG) are available on request. For reasons of production technology, the width of the flanges should be the same.

b_OG = b_UG ; t_OG =<> t_UG

In exceptional cases, however, bOG = bUG ± 50 mm is possible with the same flange thickness.

Designation is as a WTS - girder.

For example: WTS 1250 - 300 x 15 / 300 x 12
