About This Report
This industry profile for Other Aluminum Rolling, Drawing, and Extruding (NAICS 331318) draws on data from the U.S. Census Bureau[5], Bureau of Labor Statistics[9], and SBA size standards database[6]. Published by Fair Market Value and updated quarterly, it provides valuation professionals, metals industry analysts, and aluminum fabrication investors with current market data. All quantitative claims are sourced to publicly verifiable databases.
Industry Definition & Overview
Other Aluminum Rolling, Drawing, and Extruding (NAICS 331318) encompasses establishments primarily engaged in rolling, drawing, or extruding shapes from purchased aluminum or recovering aluminum from scrap and processing it into shapes in integrated mills per the U.S. Census Bureau[4]. Activities include aluminum extrusion through heated dies, drawn tube production, bar and rod rolling, bare aluminum wire drawing, and structural shape manufacturing. This classification excludes flat-rolled sheet, plate, foil, and welded tube covered under NAICS 331315.
Aluminum extrusion represents the dominant activity in this classification, with extruders pressing heated aluminum billet through shaped dies to produce custom profiles for construction window frames, curtain wall systems, solar panel mounting, automotive structural components, and industrial heat sinks. Per Census Bureau[5] data, over 310 establishments employ roughly 28,200 workers with annual payroll exceeding $1.7 billion. Extrusion press capacity ranges from small presses producing detailed profiles for electronics enclosures to large presses handling structural shapes for bridge decking and rail car construction. Drawn aluminum tube serves HVAC condenser and evaporator coil applications where aluminum offers weight and corrosion advantages over copper. Wire drawing operations produce bare aluminum conductor for electrical transmission and distribution cable manufacturing.
Per the SBA Table of Size Standards[6], the size standard is 750 employees. The EPA[7] regulates emissions from extrusion press quench systems, anodizing operations, and powder coating lines. OSHA[8] enforces safety standards for extrusion press operation, billet heating, and material handling in aluminum processing facilities.

What is aluminum extrusion?
Extrusion forces heated aluminum billet through a shaped die to produce linear profiles with custom cross-section geometry per Bureau of Labor Statistics[9] industry classification, creating window frames, structural members, and heat sinks.
What are the largest end markets?
Construction applications including window frames, curtain walls, and solar mounting systems represent the largest demand segment per Census Bureau[5] shipment data, followed by transportation, electrical conductor, and industrial machinery applications.
What is the difference from aluminum sheet?
What environmental regulations apply?
The EPA[7] regulates emissions from extrusion press quench systems, anodizing chemical baths, and powder coating operations, with additional standards for wastewater treatment and solid waste management at aluminum processing facilities.
What safety standards apply?
OSHA[8] enforces workplace safety standards for hydraulic extrusion press operation, billet heating furnace procedures, hot metal handling, and machine guarding requirements specific to aluminum extrusion and shape processing environments.
