Engineering
Validated by Engineering, Not Marketing
Structural performance has been evaluated through engineering calculations, simulations, and physical testing in cooperation with Kaunas University of Technology.
KTU structural verification
Structural performance verified in cooperation with Kaunas University of Technology.
Computational simulations
Structural behaviour assessed through engineering simulation before manufacturing.
Physical load testing
Wind and snow load performance evaluated through physical testing.
SIGMA profile geometry
A proprietary profile engineered for higher bending and torsional resistance than a standard C-profile.
Z330 / Magnelis corrosion-resistant steel
DX51D Z330 galvanized steel, or S350GD + ZM310 Magnelis®, per EN 10346.
Quality-controlled manufacturing in Lithuania
Structures are manufactured in Lithuania from European steel under controlled production processes.
Design Methodology
Wind and snow design methodology
Snow load reference
up to 1.6 kN/m²
Wind load reference
up to 24 m/s
Reference design loads documented in the SF-V2M36 technical sheet. Actual design loads are calculated per project site (snow zone, terrain, exposure) and are not a substitute for a project-specific structural calculation.

Profile Engineering
SIGMA profile comparison
~14%
~14% higher bending resistance than a standard C-profile
~23%
~23% higher torsional resistance than a standard C-profile
Comparative percentages come from the supplied structural evaluation against a standard C-profile and should not be presented as a universal guarantee for every configuration.
Materials
Material and corrosion protection
