Load-Bearing Sheet T153-40L-840
Height and optimal geometry of the T153 makes it the strongest load-bearing sheet in our portfolio.
This product is optionally available with following sustainable features:
- Steel profile made of recycled steel (SSAB Zero) for significantly lower CO2 emissions and high circularity (Ruukki LowCarbon)
- Availability and delivery time for different thickness/coating combinations varies.
For the optimal structural dimensioning, use Ruukki’s roof dimensioning software, Poimu.

Design tools
Poimu software for dimensioning load-bearing sheets
Dimensioning software, Poimu, allows you to optimise product choice according to the Eurocode. Simply by defining some basic input data you can select a load-bearing sheet for their needs from Ruukki's selection. This quick optimisation tool covers 1-, 2-span and continuous structures and gives the exact solution as to what sheet should be used, as well as its length.

Corrosion resistance
Due to requirement regarding corrosion resistance perforated steel sheets may be applied only indoors and as follows:
Galvanized steel sheets with zinc coating 275 g/m2 or galvanized steel sheets with zinc coating 100 g/m2 or 275 g/m2 together with organic coating SP 25 (polyester 25 µm) - in corroding medium C1 and C2 as per EN ISO 12944-2.
Load bearing profile application
Load bearing profiles are usually applied in multi layer roofing constructions. Sound absorption can be improved and adjusted by profile perforation selection and insulation layer selection. Perforation leads to improved sound absorption that can greatly improve indoor acoustic conditions; reduction of sound reverberation time and background noise level even without extra acoustic layers and involved costs.
Use of POIMU software enables trapezoidal sheets within a structure to be dimensioned and optimized with perforated profiles too. For more information on POIMU visit Ruukki Design Tools.
Perforation pattern
Standard degree of perforation is 15% within the area perforated for web perforated profiles.

Anticondensation layer
Profiles with anti-condensation layer are protected against water condensation directly at the bottom surface of the metal sheet. The layer absorbs water which then may be evaporated into the surrounding environment during a change in weather conditions.
Perlite coat, sprayed only on the bottom surface (back coating side) of the profile.
