332313: Plate Work Manufacturing
The code for shops that turn purchased plate into weldments, bases, bins, and heavy fabricated parts by cutting, forming, and welding.
NAICS 332313 in numbers
This code is buyer-concentrated and mostly small orders. Over FY2001 to FY2026 there were 8,252 awards worth $5.47B to 450 distinct vendors. The Naval Reactors Laboratory Field Office accounts for most of the dollars, with 17 awards totaling $4.72B. The Army's TACOM HQ made 191 awards worth $250.14M, and LOG-9 made 412 awards worth $115.61M. Other named buyers are HQ Contract Operations (CG-912), SILC BSS, and the Albuquerque Operations Office. The median award is $7.9K, so most buying is small even though a few large awards carry the totals. The notice does not say how these buyers select vendors beyond the set-aside data.
Competition signals are mixed. Most awards, 5,354 of them, are recorded with no set-aside. The next largest group is 1,907 awards tagged SBA, with smaller counts under other codes, and 790 awards with no set-aside recorded. The notice does not explain each code, so a firm should check the meaning of any code before deciding. The count of 450 distinct vendors across 8,252 awards suggests repeat buying from a set of suppliers, though the notice does not give vendor-level share. A firm deciding whether to pursue this code should weigh the small median award against the very large Naval Reactors totals, and the notice does not say how open that buyer's work is to new suppliers.
For the next year, watch the pipeline. There are 8 active notices now. There are also 44 contracts ending within 12 months, worth $8.93M in total. Those endings may point to recompetes, though the notice does not say whether they will be recompeted or extended. Track which buyers those 44 contracts belong to, and check the set-aside code on each active notice before you bid. Because the notice does not describe future budgets or program plans, treat the ending contracts as a list to research, not a forecast.

What this code covers
Census defines 332313 as plants that make fabricated plate work by cutting, punching, bending, shaping, and welding metal plate they buy from a mill or service center. The plate is heavier than sheet, and the output is usually a welded assembly rather than a formed panel.
Defense and aerospace buyers use this code for machine bases, skids, weldments that get finish machined, armor and ballistic plate assemblies, hoppers and chutes, blast deflectors, ship structural pieces, and heavy brackets. Many plate shops also do the burning, beveling, and stress relief before a machine shop takes over. Structural frames belong in 332312 and heavy gauge tanks have their own code.
What federal buyers typically ask for
Shipyards, Army depots and arsenals, Navy fleet readiness centers, and NASA centers post most of the plate work you will see. DLA posts some under the land and maritime supply chains for weldment spares. The work is usually build-to-print with a drawing package and a welding specification.
Welding drives the quality terms. Expect welder and procedure qualification to a named code, weld inspection records, and for naval work a specific fabrication and inspection document set. Mill certs for each heat, dimensional inspection, and a certificate of conformance are standard. Armor plate carries its own material specifications, and DFARS specialty metals applies to steel and titanium in weapon system items. Some drawings are export controlled.
Small business set-asides are common for spares and small weldments. Larger shipyard and depot jobs often go unrestricted, but many still land with small fabricators.

Many plate weldments are bought under the PSC of the end item, such as a vehicle or ship component.
Before you bid
Find the welding specification before you quote. Naval and armor work can require qualification records, inspection steps, and documentation that add real cost if you have not done them before.
