Typical applications

FH420-FH460 is normally specified for jack-up legs and spud cans, fixed and mobile offshore platform structures, wind-turbine installation vessels, and heavy marine lifting equipment.

We supply it cut to size by plasma, laser or waterjet, with edges machined or flame-cut to your drawing, and can deliver in the heat-treatment condition your fabrication procedure requires.

Rolled and drilled thick sections cut for offshore structures
Rolled, drilled and flame-cut thick sections — the kind of heavy detail work offshore structures require.

Delivery condition
