At Conrex Steel, we manufacture segmental tank heads, servicing a wide variety of industries. With over 60,000 sq./ft of production space, we have the capabilities to produce large diameter heads efficiently, without compromising on quality. We can also fabricate, trial fit, match mark, knock-down, or tack weld our tank heads with trimmed, tapered or beveled edges. From either normalized or as-rolled plates, our head types range from Semi Elliptical, Flanged and Dished, Toriconical, Double Knuckle Cone, Toroidal, Hemispherical and Dished Only.

Our in-house robotic trimming allows for faster production while maintaining a high level of accuracy. With our capabilities to date, we can produce segmental heads ranging in diameter from 20′ to 120′ (in house), and thicknesses of 1/4in up to 5 1/2in nominal gauge.
