Rectangular Tanks

Rectangular storage tanks can be built to a variety of sizes and can be furnished for atmospheric pressure, or with special considerations include internal and external pressure. All materials are available including stainless steel, nickel alloys and reactive metals.

Rectangular storage tanks are typically less cost effective than cylindrical tanks, however, they are ideal for maximizing available floor space and have some advantages for mixing and material handling.

We can also design a system around your storage tank to include pumps, pressure/temperature measuring equipment, and lifting/filling equipment.

Our general design parameters for rectangular storage tanks is:

  • 15"-6" Wide (4.7m)
  • 17'-0" High (5.2m)
  • 125'-0" Long (38.1m) long
  • 40,000 lbs (18,000 kg)
  • Internal pressure dependent on design


  • Sloped
  • Flat
