What is LGSF?

Light Gauge Steel Framing
Technology

LGSF is a construction technology using cold-formed steel produced by highly advanced and precise machinery. This method is highly efficient and can be adopted to practically any building type. It is also environmentally sustainable and produces a strong, high-performing structure.

Light Gauge Steel Framing (LGSF) uses cold-formed steel sections as the primary structural frame. It is suitable for fast, durable, and precise construction across various building types — from mining camps and industrial housing to commercial buildings and modular pods.

What Is Cellular Concrete?

Cellular concrete is a lightweight, flowable cement-based material filled with air bubbles. It offers good thermal insulation, load distribution, and speed in construction — making it the ideal foundation system paired with LGSF structures.

Why Combine LGSF with Cellular Concrete?

The Combined System Advantage

Pairing LGSF with Cellular Concrete delivers a construction system that is faster, stronger, and smarter than traditional methods.

Faster Installation
Cellular concrete raft foundations cure quickly — enabling faster overall project timelines with up to 50% savings in construction time.
💧
Dry Construction
No bricklaying and less water usage — ideal for remote sites and areas with limited water supply or during rainy seasons.
🌍
Seismic Resilience
LGSF + Cellular base absorb earthquake shocks — ideal for seismically active regions of Indonesia including Kalimantan.
🌡️
Thermal & Acoustic Insulation
Multi-layered wall systems combined with insulated foundation provide superior thermal and acoustic performance vs. conventional construction.
⚖️
Lightweight Yet Strong
LGSF construction is 1/10th the weight of a brick wall — huge savings in transportation costs, ideal for remote and modular housing.
♻️
Environmentally Friendly
Uses galvanized steel with 100-year+ lifespan. Sustainable, minimal waste, energy-efficient with insulating materials significantly better than brick.

Comparison

LGSF vs Conventional Construction

A detailed comparison between traditional Brick & RCC construction and modern LGSF construction.

Brick & RCC Construction LGSF Construction
Quality of construction varies as materials sourced from different vendors.All materials are of uniform quality.
Huge transportation costs as all materials are heavy.Huge savings in transportation — LGSF is 1/10th the weight of brick wall.
Uneven surface requires more plastering material and reduces carpet area by 25%.Straight finished surface reduces carpet area by only 10–15%.
Brick walls are more prone to shrinkage cracks.Dry walls do not experience shrinkage cracks.
Wet construction — time consuming, involves curing at various stages.Dry and fast construction — no curing needed.
Life of the building and durability using CFS framework varies.Expected lifespan of 100 years — durability subject to user care.
Waterproofing and patches on walls are common issues.Method and workmanship take care of waterproofing issues.
External and internal finishes require more work.Stucco, tiles, stones, paints work well — cleaner lines than brick.
Hollow sound / sound transfer in wall structures.Rockwool / CLC cavity fill delivers STC above codes.
Insulation leading to energy savings is limited.Infill material has substantial improvement over brick wall insulation.
Door and window openings require additional work due to uneven surfaces.Better accuracy of openings in steel framing.
High time factor and financial interest burden of RCC construction.Faster timeline reduces financial interest burden significantly.
CFS framework perceived as more expensive than RCC construction.Direct costs at PAR; higher carpet-to-built-up ratio is a key USP.
