Metal Studs

Metal studs are a vital component in modern construction, providing lightweight, fire-resistant, and durable framing systems for both residential and commercial buildings. From interior partitions to complex curtain wall systems, metal studs are widely used across industries. This guide explores everything you need to know about metal studs—including materials, sizes, profiles, installation methods, and a list of the top manufacturers in the USA and globally.

1. What Are Metal Studs?

Metal studs are framing components made from cold-formed steel, typically used as a substitute for wood in non-load bearing wall applications and increasingly in load-bearing walls due to improved engineering standards. They are primarily made from galvanized steel and are shaped through roll forming.

2. Materials Used in Metal Studs

a. Common Materials:

• Galvanized Steel (G40, G60, G90) – Zinc-coated for corrosion resistance

• Stainless Steel – For marine or corrosive environments

• Aluminum – Lightweight and corrosion-resistant, but less common

• Cold-Rolled Steel (CRS) – Used in high-strength applications

b. Material Grades and Coatings:

• ASTM A653 is the common standard for cold-formed galvanized steel.

• Galvanization levels (G40, G60, G90) indicate zinc thickness and corrosion protection.

• Optional coatings: epoxy, powder coating, or paint (for custom applications)

3. Metal Stud Profile Types

a. C-Stud (C-Shaped Channel)

• Most commonly used in wall framing.

• Available in various flange widths and depths.

• Has small return lips for strength and screw anchoring.

b. U-Track (Runner Channel)

• Used at the top and bottom of a wall system to receive the studs.

• Typically the same width as the stud it supports.

c. Furring Channel (Hat Channel)

• Shaped like a hat, used to fur out walls or ceilings.

• Common in acoustic and drywall applications.

d. Z-Furring Channel

• Designed for thermal insulation systems and used vertically on walls.

e. Box Studs / Back-to-Back C-Studs

• Used for high-load conditions such as wind-bearing or axial-load walls.

f. Slotted Studs

• Allow vertical deflection movement without affecting wall integrity.

4. Common Metal Stud Sizes

Other Dimensions:

• Thickness: 0.4 mm to 2.5 mm (16–25 gauge)

• Lengths: Typically 2.4m, 2.7m, 3m, or cut-to-length up to 6m+

5. Industry Applications

a. Construction

• Interior partition framing

• Curtain wall systems

• Soffits and ceilings

b. Industrial

• Cleanrooms and controlled environments

• Warehousing partitions

• Steel framing for modular buildings

c. Commercial

• Office partitions

• Retail shopfitting

• Hotels and hospitals

d. Residential

• Basement wall framing

• Drywall support systems

• Load-bearing steel framing in multi-story homes

6. Benefits of Using Metal Studs

• Fire-resistant: Non-combustible material

• Durability: No rot, termites, or warping

• Consistency: Precision-formed from roll forming machines

• Lightweight: Easier to handle and install

• Sustainable: 100% recyclable steel

7. Metal Stud Installation Overview

• Step 1: Measure and snap lines on the floor and ceiling

• Step 2: Secure the bottom and top tracks

• Step 3: Cut studs to size and insert into the track

• Step 4: Screw studs through track flanges using self-drilling screws

• Step 5: Install electrical and plumbing through pre-punched holes

• Step 6: Add drywall and finish

8. Common Standards and Codes

• ASTM C645 – Non-structural framing

• ASTM C955 – Load-bearing steel framing

• AISI S240 – North American standard for cold-formed framing

• UL Listings – For fire-rated assemblies

11. FAQs

Q: What gauge metal stud is used for load-bearing?
A: Typically 16 to 20 gauge (1.2mm to 1.5mm thick) studs are used for structural load-bearing walls.

Q: Are metal studs cheaper than wood?
A: In many regions, especially in commercial projects, metal studs can be more cost-effective due to durability and lower maintenance.

Q: Can metal studs hold heavy weight like TVs or cabinets?
A: Yes, with proper backing or fasteners, metal studs can support significant weight.

Q: Are metal studs recyclable?
A: Yes, they are 100% recyclable and are often made from recycled steel.

Q: Can you cut metal studs on-site?
A: Yes, using snips for light-gauge studs or power tools for thicker ones.

Conclusion

Metal studs are indispensable in today’s fast-paced construction environment. They offer versatility, precision, and durability across a wide range of industries and projects. Whether you're outfitting a high-rise in New York or installing drywall in a suburban home, metal studs provide a dependable framework for your structure.
