🧱 Wall Framing Calculator (Steel Framing)

Calculate studs, tracks, and materials for wall partitions with steel framing. Includes 2D/3D visualization.

📐 Calculation Methodology for Steel Frame Wall Partitions

The Steel Framing construction system (also known as light gauge steel or cold-formed steel) uses galvanized steel profiles to create lightweight yet strong structures. This calculator implements international ASTM standards and building codes to ensure precise, professional calculations.

🔩 Studs (Vertical Members)

Studs are the vertical C-shaped profiles that form the wall structure. They are installed at 16" on center (standard spacing) or 24" for non-load-bearing walls. The calculator automatically determines the quantity based on wall width and allows you to select commercial lengths of 10ft, 20ft, or 40ft to optimize cuts and minimize waste.

📏 Tracks (Horizontal Members)

Tracks are horizontal U-shaped profiles installed at the floor and ceiling. They serve as guides for anchoring the studs. They are calculated as twice the width of each wall (top track + bottom track).

⚠️ Corner Reinforcements

At each L-joint (corner), an additional reinforcement stud is added. This ensures structural rigidity and provides a fixing surface for sheathing panels on both sides of the corner.

🔧 Fastening Screws

4 screws per stud are calculated (2 at top connection + 2 at bottom). Self-drilling pan-head screws 8mm x 1/2" are used for metal-to-metal connections.

📊 Approximate Material Requirements per 100 sq ft

Reference values for a standard 8ft tall wall with studs spaced at 16" on center:

Material	Quantity	Unit	Notes
Studs C 60x38x0.85mm	26-28	linear feet	Approx. 11 studs
Tracks U 61x25x0.85mm	8-9	linear feet	Floor + ceiling
Screws	44-48	units	4 per stud
Drywall 1.2x2.4m	4	sheets	1 extra (x2)

📖 Glossary: What is the Steel Framing System?

Steel Framing is a construction system known by different names depending on the country:

🇨🇱 Chile: Metalcom, Dry Partition
🇺🇸 USA: Steel Framing, Light Gauge Steel
🇪🇸 España: Metal Profiles, Steel Frame
🇲🇽 México: Metal Drywall, Drywall
🇦🇷 Argentina: Steel Framing, Durlock
🇧🇷 Brasil: Steel Frame, LSF

Advantages of Steel Framing

Installation speed: Up to 3 times faster than traditional masonry
Lower structural weight: Reduces loads on foundations and slabs
Seismic resistance: Controlled flexibility during seismic events
Thermal & acoustic insulation: Facilitates mineral wool installation
Clean construction: No mortar or wet debris

❓ Frequently Asked Questions about Steel Framing

How many self-drilling screws do I need per sq ft of steel framing?

For metal-to-metal connections in the structure, you need approximately 4-5 self-drilling screws per 10 sq ft (stud-track connections). To attach drywall sheets to the structure, an additional 25-30 screws per sheet (4x8ft) are required, installed every 6-8 inches on studs.

What is the official spacing for load-bearing vs partition walls?

According to building codes and international standards: Load-bearing walls require studs every 16 inches (structural modulation). Non-load-bearing partition walls can use spacing up to 24 inches. For seismic zones, 16 inches is always recommended regardless of wall type.

What gauge steel should I use for steel framing partitions?

For non-load-bearing interior walls: 25-gauge (0.50mm) to 20-gauge (0.85mm) profiles are sufficient. For structural walls or heights over 10ft: use 20-gauge or heavier profiles. In coastal climates, always use steel with G90 galvanization.

How do I calculate materials for a wall with a door or window?

Openings require additional headers and sills. For a door: add 2 reinforcement studs + 1 horizontal header. For windows: add 2 reinforcement studs + 1 header + 1 sill. This calculator calculates the base structure; for openings, add 15-20% extra stud profiles.
