Custom Tank Components

We fabricate tank components including heads, cylinders, heat transfer surface, manways. In addition, we also have bar, angle and pipe rolling capabilities.


Custom Metalcraft builds custom fabricated tank heads from some of the most challenging alloys in the industry, including Hastelloy® , AL-6XN® and Titanium.  We fabricate heads up to 3/4″ thick with diameters from 16″ to 168″.  Heads can include heat transfer surface.

Cross Arm Manway

CMC18A ManwayOur CMC 18A manway is designed for atmospheric service above the liquid level of a tank. It features a quick opening design, easy gasket replacement, and can be fabricated from nearly any stainless steel or nickel alloy material.

Bolted Manway

Bolted manwayFor higher pressure applications, our LMB series manway can be custom built to withstand higher pressures and temperatures than many quick opening or tongue-and-groove manways. It features a flat gasket, and is ideal for applications requiring a 150# or 300# class flange, but without the extra weight of a blind flange. Hinges, davits or spring assists can be added to any manway.

Quick Opening

  • 0-3 psi cross arm
  • Sanitary pressure rated
  • 8″ to 48″

High Pressure Bolted

  • Suitable for Garlock® or PTFE gaskets (Teflon®)
  • 16″ to 48″

In Swing

  • Static pressure
  • ASME code


  • Quick opening
  • Bolted

Drum Cover

  • Hinged
  • Locking


Custom Metalcraft can roll form a variety of shapes from some of the most challenging alloys in the industry, including Hastelloy® , AL-6XN® and Titanium.
