High-yield S350GD structural steel with 275 g/m² hot-dip zinc coating. CNC roll-formed to sub-millimeter tolerances with 50+ year anti-corrosion protection.
Micro-alloyed structural zinc-galvanized steel engineered to Eurocode 3 standards with continuous robotic tolerances under ±0.5mm.
With a certified yield strength of 350 N/mm² (compared to standard structural steel at 235 N/mm²), S350GD provides unprecedented strength-to-weight ratio, slashing building weight by up to 70% vs. reinforced concrete.
A heavy 275 g/m² zinc coating delivers sacrificial cathodic protection. Even if punched or drilled, the zinc layer naturally oxidizes to heal exposed edges, preventing any red rust initiation.
Unlike timber that warps, cracks, or rots with humidity, steel is dimensionally stable forever. Walls remain 100% straight and plum, preventing drywall cracking and door sticking over decades.

When enclosed within our weatherproof wall assembly, galvanized S350GD steel experiences virtually zero corrosion, with tested design lifespans exceeding 100 years—completely immune to concrete carbonation and rebar spalling.
We exclusively use S350GD structural steel hot-dip galvanized with Z275 (275 g/m² zinc coating, EN 10346). This structural grade provides a guaranteed yield strength of 350 MPa and self-healing sacrificial cathodic corrosion protection.
Yes. Thanks to 3D BIM parametric modeling and automated multi-axis CNC roll-forming, our framing can achieve clear spans up to 9.5 meters, double-height open living spaces, cantilevered terraces, and curved or geometric roof structures with zero site cutting.
