MASTER CTS / Building Systems
MASTER GREEN BUILDING is an integrated light steel building system under MASTER CTS (ASATEEN GROUP). Basis: Light Gauge Steel (LGS) / Cold-Formed Steel (CFS).
Industrialized LSF/LGSF structural and envelope integration: GFRP reinforcement, cold-formed steel framing, autoclaved fiber cement boards, foam concrete core infill, and fired-clay façade units. Delivery: coordinated off-site manufacturing and on-site mechanical assembly.
One coordinated building family under MASTER CTS—not a standalone brand or single product line. Five integrated application tracks share the same engineering, manufacturing, and assembly logic.
Orientation
Technical anchors for executive scan. Full parameters, tables, and track data follow in dedicated sections.
Technical scope
Formal system name, developer, classification, application scope, assembly rules, and manufacturing tolerance—same facts as the controlled technical basis.
System type
Industrialized LSF / LGSF
Institutional line
MASTER CTS (ASATEEN GROUP)
Delivery model
Off-site prefabrication + on-site mechanical fastening
Frame tolerance
± 1.0 mm
Controlled framework
Software-led design and factory-controlled profiles—not site improvisation. U/C roll-formed framing is produced before deployment.
Design and detailing software, structural analysis, and manufacturing software drive U and C profiles. Web sizes and thickness bands are track-specific; frames leave the factory as defined assemblies.
Engineered stack (coordination sequence): MASTER BAR → LSF STRUCTURE → MASTER BOARD → MASTER FOAM CONCRETE → MASTER BRICK (with MASTER NANO where specified in the façade layer).
On-site assembly sequence: foundation reinforcement → load-bearing LSF frame → envelope / permanent formwork → injected cavity infill → exterior façade and protection layer.
Stack layers (role)
Principal components
Role, technical basis, and selected data for each layer of the coordinated stack.
The table lists the five principal components. "Selected data" are documented reference values; project-specific design governs field use.

Five integrated tracks
Tracks A–E are deployment contexts within one MASTER GREEN BUILDING system—not separate brands or disconnected product lines.
Map program type to track for scope and examples. Configuration quantities and production parameters for each track appear under Track data and Production logic.
Track A
Fully engineered pod units for wet rooms and repeatable bathroom cores.
Typical use
Rapid installation where bathroom repetition and quality control matter.
Example programs

Typical use
Reduced seismic force demand via lower structural weight combined with detailing and code-based engineering.
Example programs
Same residential family context as Track B, with engineering emphasis on mass, connections, and structural definition for seismic regions.
System indicators
Qualitative themes first; quantitative deltas in the table. Baseline labels are descriptive comparators—not project-specific guarantees.
Use the list for thematic orientation; use the table for schedule, mass, energy, waste, transport, reinforcement energy, and thermal resistance figures.

Configuration data
Representative project-example metrics (profiles, steel, connections, hours). Documented references—not universal guarantees for every site or code regime.
Expand each block for the full metric list. Numbers are preserved as in the controlled source; use Production logic for factory and profile-band detail by track.
Standard residential — example quantities
Larger residential — example quantities
Manufacturing and deployment
Controlled roll-forming, software chain, and profile bands per deployment context. Final detailing remains project-specific and code-led.
Pair this section with Track configuration for example quantities and hours. Each block below states manufacturing and profile rules for that track—not field installation steps.

Seismic engineering layer
Mass–force relationship in code-based design, plus documented analysis and documentation scope. Complements Track E configuration and production bands.
Read with comparison indicators and Track E tuning range. Outcomes depend on site, soil, and applicable codes—not on system label alone.
Lower structural weight can reduce seismic force demand when combined with proper analysis, detailing, and code-based structural design.
That relationship is engineering context—not a universal claim independent of site conditions, soil–structure interaction, or the governing building code.
Design and documentation scope includes:
Design reference basis
Documented design-reference basis for cold-formed and steel design workflows. Listing does not imply project-specific certification, blanket compliance, or regulatory approval.
Eurocode steel suite items below pair with AISI S100 for typical cold-formed workflows; use with the seismic and structural statements elsewhere on this page.
