ABSTRACT
This specification covers the installation and erection requirements for load bearing (transverse and axial) steel studs and related accessories. Materials requirements for framing members, zinc-rich paint, steel drill screws, and power actuated drive pins are also covered in this specification. Products shall be protected from adverse weather and job site conditions that will cause any physical damage. Materials shall be stored on a flat plane, and any damaged materials shall be removed from the job site immediately. Materials fastening, attachment, and tolerances shall conform to the requirements covered in this specification. Methods of material construction shall be either stick built or panelized. For panelized construction, panels shall be designed to resist all construction and handling loads as well as live loads. Handling and lifting of prefabricated panels shall not cause permanent distortion in any member or collateral material, and all stud-to-track connections shall be installed prior to hoisting the panel. Attachment of the panel to the structure shall be as shown on the design drawings, and all panels shall be aligned to provide continuity of any wall/floor surface. For stick built (non-panelized) members, tracks shall be aligned accurately at supporting structure and shall be fastened to the structure. Track intersections shall butt evenly, and doors, windows, and other items installed in the wall shall be securely anchored to the wall by means of clips, angles, screws, bolts, etc.

Overview

ASTM C1007-20: Standard Specification for Installation of Load Bearing (Transverse and Axial) Steel Studs and Related Accessories provides comprehensive requirements for the proper installation and erection of structural steel studs and associated elements in load-bearing applications. Developed by ASTM International, this standard addresses both materials and installation methods to ensure consistent quality and structural integrity in buildings utilizing steel framing systems.

This specification applies to load bearing steel studs and accessories ranging in thickness from 0.0329 in. (0.836 mm) to 0.1120 in. (2.845 mm), covering best practices for construction, attachment, finishing, and safe handling of these elements. It aligns with other relevant industry standards, ensuring a harmonized approach to steel stud framing in both stick built and panelized construction methods.

Key Topics

• Material Requirements: Specifies criteria for steel studs, tracks, bracing, and related accessories; includes zinc-rich paints, rust-inhibitive drill screws, and power-actuated drive pins. Ensures only undamaged, properly stored materials are used.
• Installation Practices: Outlines correct procedures for installing steel studs, including alignment tolerances, anchorage to structures, connection types, and methods for both stick built and panelized assemblies.
• Load Considerations: Defines requirements for axial and transverse load support, proper placement of studs, headers, jack studs, and cripple studs, ensuring structural performance.
• Fastening and Attachment: Details appropriate use of welds and screws, standards for penetration and minimum number of exposed threads, and prohibits certain attachment methods such as wire tying.
• Panelized vs. Stick Built Construction: Distinguishes between panelized (prefabricated) and stick built (on-site) installation techniques, emphasizing best practices for preassembly, handling, and on-site integration.
• Quality and Safety Controls: Covers the need for temporary bracing, protection from environmental factors, storage protocols, and immediate removal of damaged materials.

Applications

ASTM C1007-20 is widely used in the design, construction, and inspection of:

• Commercial and Residential Buildings: For framing load-bearing walls, floors, and ceilings using steel structural elements.
• Prefabricated Construction: Enables efficient installation and transportation of preassembled wall panels, reducing on-site labor and maintaining quality control.
• Renovations and Retrofits: Ensures upgrades to existing structures with steel studs meet current installation quality and safety standards.
• Code Compliance: Used by architects, engineers, contractors, and inspectors to demonstrate conformity with building regulations, ensuring safety and durability in load-bearing steel stud assemblies.

By following this standard, project teams benefit from increased construction consistency, high structural integrity, and reduced risks associated with improper installation.

Related Standards

ASTM C1007-20 references several key standards and resources, further supporting best practices and integration with other industry requirements:

• ASTM C11: Terminology Relating to Gypsum and Related Building Materials and Systems
• ASTM C841: Specification for Installation of Interior Lathing and Furring
• ASTM C954: Specification for Steel Drill Screws for steel studs
• ASTM C955: Specification for Cold-Formed Steel Structural Framing Members
• ASTM C1063: Specification for Lathing and Furring for Portland Cement-Based Plaster
• AISI S100/S202/S240: North American standards for the design and practice of cold-formed steel structural members and framing
• AWS D1.3: Specification for Welding Sheet Steel in Structures
• MIL-P-21035: Paint, High Zinc Dust Content, Galvanizing Repair
• FF-P-395: Pin, Drive, Guided and Pin Drive, Power Actuated Fasteners

These related standards help ensure interoperability and comprehensive quality control throughout the steel stud framing process.
