331221 - Rolled Steel Shape Manufacturing

Introduction

If you're exploring the manufacturing industry, understanding NAICS code 331221 is vital. This code specifically covers Rolled Steel Shape Manufacturing, a critical segment of the steel production sector. The products made under this category, such as beams, channels, and angles, serve as essential building blocks in construction, infrastructure, and various manufacturing applications. Whether you’re a contractor, supplier, or industry professional, knowing the details of NAICS 331221 can help you navigate government contracting, regulatory compliance, and market analysis effectively.

What is NAICS Code 331221?

NAICS code 331221 refers to the Rolled Steel Shape Manufacturing industry. Businesses under this classification engage in producing steel shapes by rolling steel billets or slabs. The rolling process transforms raw steel into standardized shapes that are crucial for structural integrity in diverse engineering projects.

Key Activities in Rolled Steel Shape Manufacturing:

• Rolling steel billets, slabs, or purchased steel into shapes like beams, channels, and angles
• Producing reinforcing bars (rebar) used in concrete construction
• Manufacturing steel bars, rods, sheets, strips, and other steel profiles via cold or hot rolling processes

Sector and Typical Business Activities

Sector: Manufacturing

NAICS 331221 falls squarely within the Manufacturing sector, specializing in converting steel into usable structural components. Typical businesses include:

• Steel beam manufacturers
• Steel channel production companies
• Steel angle fabricators

These businesses support multiple industries such as construction, infrastructure development, automotive, and heavy equipment manufacturing.

Size Standards and Eligibility

For federal contracting and small business purposes, the size standard for NAICS 331221 is generally 1,000 employees. Companies with workforces smaller than this threshold are typically considered small businesses under this NAICS code for SBA programs and government procurements.

Examples of Businesses Under NAICS 331221

• Steel Beam Manufacturing Companies: Producing I-beams and H-beams used in high-rise buildings and bridges.
• Steel Channel Producers: Creating channels used for framing and reinforcement in commercial and residential construction.
• Steel Angle Fabricators: Manufacturing L-shaped steel angles utilized for structural supports and braces.
