Metal Fabrication Requirements for Commercial Buildings

Commercial building projects involve complex metal fabrication requirements that must meet stringent codes, specifications, and quality standards. Understanding these requirements helps contractors ensure successful project outcomes and avoid costly rework or delays.

Structural Steel Requirements

Structural metal components in commercial buildings must comply with specific codes:

• AISC Standards: All structural steel must be fabricated to American Institute of Steel Construction standards
• AWS D1.1: Welding procedures must meet Structural Welding Code requirements
• International Building Code (IBC): Compliance with latest edition for structural requirements
• Load Calculations: Fabricated components must meet engineered specifications

Architectural Metal Specifications

Architectural metal features require attention to both aesthetics and performance:

• Finish Requirements: Specified finishes from prime paint to architectural coatings
• Tolerance Standards: Dimensional tolerances for architectural fit
• Material Specifications: Correct alloy selections for environment exposure
• Shop Drawing Approval: Submittal process before fabrication begins

Fire and Life Safety

Fire-rated assemblies and life safety components have specific requirements:

• Fire-Rated Assemblies: Components must meet UL or assembly fire ratings
• Spray-Applied Fireproofing: Coordination for application after installation
• Egress Components: Stairs, guards, and rails must meet egress code requirements
• Inspection Requirements: Third-party inspection often required for structural connections
