4C manufactures and supplies a kit-of-parts for virtually any type of building that delivers the structure and exterior envelope. The kit is comprised of three distinct product families, a panelized wall system that integrates LGS framing, insulation, fire-rated sheathing, and WRB into a single, high-performance building component, interior prefabricated steel wall panels, and prefabricated roof and floor framing components.
4C also provides design and installation services associated with our system.
4C SAFE Panel
Structurally Capable,
Architecturally Flexible,
Fire-Resistant,
Energy-Efficient
Prefabricated, fire-rated, non-combustible exterior structural wall panel. These panels offer R-values suitable for all climate zones and come factory-assembled for quick and easy installation of MEP systems and traditional interior and exterior finishes on-site.
Cheaper – Cost savings extend beyond the hard costs to time, labor, waste, and overall project efficiency.
Faster – Precut, precise kits reduce assembly time, errors, and rework.
Better – Higher R-value (24+10 ci), airtight, durable, and low-carbon footprint. Meets Florida HVHZ, WUI, and fire-rated assembly standards.
✓ R24 cavity + R10 ext
✓ rated assemblies
✓ int & ext finish ready
✓ open web trusses / joists
✓ 1/8″ tolerance
✓ precut & prefabricated
Roof / Floor system
Prefabricated steel trusses or joists specific to each design, slope, and span along with class A fire-rated structural sheathing and all associated hardware and consumables.
Cost-Effective – Competitive pricing with higher performance.
Precise – 1/8” tolerance prefab steel trusses or joists to fit any span and design.
Efficient – Open-web trusses & 24” OC minimize material and waste and allow for seamless MEP design and rough-in.
Faster – Precut and prefabricated components reduce time and errors.
Prefabricated interior walls
Prefabricated Lightweight steel wall panels with exceptional fire resistant properties. The panels use Sound-Guard studs that provide exceptional acoustic performance and easy rough-in of traditional MEP systems.
Precise – 1/8” tolerance prefab frames ensure accuracy.
Efficient – No site waste, recycled steel, and integrated MEP gap for faster rough-ins.
Superior Performance – STC 52+ sound rating, 1 & 2-hour fire-rated assemblies.
Faster – Precut and prefabricated components reduce time and errors. Seamless MEP design and rough-in.
✓ STC 52+
✓ rated assemblies
✓ recycled steel
