Steel Fabrication 

Steel CNC burned parts (also known as CNC flame-cut or oxy-fuel burned components) are precision-cut steel shapes produced in fabrication shops using computer-controlled burning tables to slice thick plate material into custom profiles with remarkable accuracy and efficiency. In a small shipyard-oriented operation, this process typically starts with importing CAD/DXF files into nesting software to optimize material usage on large carbon or alloy steel plates (often A36, A572, or marine grades up to 6–10 inches thick). CNC oxy-fuel burners (or high-definition plasma for thinner stock) guide multiple torches across the bed—sometimes 20 ft × 40 ft or larger—to thermally cut complex contours, holes, bevels, and intricate shapes like gussets, brackets, base plates, doublers, or structural reinforcements for ladders, padeyes, flanges, embeds, and spreader bar components. The "burned" edge results from the high-temperature oxygen-propane reaction that melts and ejects material, leaving a relatively smooth, dross-minimized cut that often requires only light grinding or machining for weld prep or tight tolerances. This method excels for heavy, low-to-medium volume parts where full CNC milling would be cost-prohibitive, delivering quick turnaround, minimal waste, and compliance with shipyard specs (e.g., ABS tolerances), before moving to secondary operations like welding, forming, or coating for corrosion resistance in maritime environments

Custom steel fabricated spreader bars are specialized lifting devices produced in small shipyard-focused shops to safely distribute loads and maintain balance during crane lifts of heavy, awkward, or oversized marine components like hull sections, engine modules, piping skids, or equipment packages. Built primarily from high-strength structural steel (such as A36, A572, or tubular sections), these bars feature a main beam—often a fabricated box section, wide-flange, or heavy pipe—with precisely welded end fittings or padeyes incorporating machined holes for shackles, hooks, or slings, ensuring proper rigging angles and preventing sling crush or load instability. Fabrication involves plasma/oxy cutting profiles, beveling for full-penetration groove welds, multi-pass welding by certified welders to AWS or ABS standards, and often machining connection points for tight tolerances. Design adheres to ASME B30.20 or BTH-1 codes, factoring in safe working load (SWL), rigging geometry, compressive/bending stresses, and sometimes adjustable lengths via pinned or telescoping sections. Final touches include load-rated markings, non-destructive testing (e.g., UT or mag particle on welds), prime/paint with marine-grade coatings for corrosion resistance, and proof loading if required—making them essential for efficient, damage-free handling in shipyard environments.

Miscellaneous steel welding parts—often simply called "misc" or "miscellaneous steel" in shipyard and fabrication jargon—encompass a wide array of custom, smaller-scale welded components that support the overall assembly of vessels, modules, and industrial structures without being major structural elements like hull plates or main beams. In a small shipyard-focused shop, these include items such as clips, brackets, gussets, stiffeners, tripping brackets, doubler plates, lugs, pipe supports, handrail fittings, grating clips, fairleads, cleats, tie-downs, and various attachment points fabricated from mild steel angles, channels, flat bar, or plate. The process typically involves CNC burning or plasma cutting raw shapes from stock, bending or forming as needed, then fit-up and welding (using MIG, stick, or flux-core for speed and penetration) to create strong, precise assemblies that reinforce connections, provide mounting points, or distribute loads in tight or high-stress areas. These parts demand quick turnaround, adherence to tight tolerances and marine standards (e.g., ABS or NAVSEA weld procedures), and often corrosion protection via galvanizing, primer, or epoxy coatings to endure saltwater exposure. While individually small, misc steel parts are essential for completing outfitting, ensuring structural integrity, and enabling efficient shipyard installation—making them a high-volume, detail-oriented staple of fabrication work.
