Construction is shifting toward industrialized systems.

Shorter timelines, execution predictability, and resource efficiency are no longer advantages — they are requirements.

INNOSTAL develops integrated light gauge steel solutions that replace fragmented construction processes with a controlled production and assembly system.

LGS Technology

Light Gauge Steel (LGS) is a construction system based on cold-formed galvanised steel profiles used for load-bearing and non-load-bearing structures.

Components are digitally designed, CNC-manufactured, and assembled with millimetre-level precision.

Unlike traditional welded steel systems, LGS enables lightweight construction, rapid installation, and scalable prefabrication.
