Light Gauge Steel (LGS) Structures
Precision Cold-Formed Steel Framing for Commercial & Modular Buildings
Engineered for Performance & Long-Term Reliability
Yatee Light Gauge Steel (LGS) Framing Structures offer a revolutionary, lightweight alternative to conventional RCC and heavy steel framing. Engineered with precision CNC roll-forming technology from high-tensile galvanized steel (550 MPa), LGS frames provide extreme dimensional accuracy, rapid dry construction, superior earthquake resistance, and termite/corrosion immunity.
Key Technical Features
High-Speed Dry Construction
100% factory pre-assembled wall panels and roof trusses enable up to 60% faster project completion.
High Strength-to-Weight Ratio
7x lighter than concrete framing, drastically reducing foundation costs and seismic inertia.
CNC Precision Pre-Punching
Pre-punched service holes for electrical conduits and plumbing lines with zero on-site drilling.
Termite & Moisture Immune
Galvanized zinc coating (Z275 GSM) prevents corrosion, warping, cracking, and rot.
