EB Metal is proud to introduce NITROSTUD 25, 20, 30 & 33 as new drywall framing options. NITROSTUD is a lighter yet stronger, nonstructural stud, engineered and tested to the highest industry standards. As with all of our products, NITROSTUD is manufactured with mill certified, primed steel and true galvanized coatings.
NITROSTUD 25, 20, 30 and 33 are consistent with the following test models: A ASTM 1003, ASTM C 645, ASTM C 754, ASTM E 119, ASTM E 72.

ADVANTAGES:
- – EB Metal has incorporated our NITROSTUD profile to increase performance of our complete interior stud line.
- – With a design thickness of .186, NITROSTUD 25 is the thickest 25ga in the market.
- – With a design thickness of .021, NITROSTUD 20 is the thickest EQ 20 member in the market.
- – NITROSTUD 20 (50KSI) balances the requirements of the contractor, architect and engineers while providing an product that is easier to handle and cut in the field.
- – Patent Pending under the name duly registered in Canada and USA EB-NITRO-EQ-17 and EQ-EB-NITRO-20
NITROSTUD 25 Stud Section Properties Table
Table Notes
- Calculated properties are based on AISI S100-07, North American Specification for the Design of Cold-Formed Steel Structural Members.
- The centerline bend radius is based upon inside corner radii shown in thickness chart.
- Effective properties incorporate the strength increase from the cold work of forming as applicable per AISI A7.2.
- Tabulated gross properties, including torsional properties, are based upon full-unreduced cross section of the studs, away from punchouts.
- For deflection calculations, use the effective moment of inertia.
- Allowable moment includes cold-work of forming.
- For the steels that have both 33 and 50 ksi listing, if the design is based upon 50 ksi, the 50 ksi steel needs to be specified. (example: 3625 S137 16-50 (50 ksi)).
- Webare ignored.depth for track sections is equal to the nominal height plus 2 times the design thickness plus the bend radius. Hems on non-structural track sections.
