Due to the harsh working environment of the ship, the hull shell is subject to chemical
corrosion of seawater, electrochemical corrosion and corrosion of
marine organisms and microorganisms; the hull is subjected to large
wind and wave impacts and alternating loads; the shape of the ship
is complicated by processing methods, etc. Steel for hull structure
is strictly required. First of all, good toughness is the most
critical requirement. In addition, high strength, good corrosion
resistance, weldability, forming properties and surface quality are
required.
Shipbuilding Steels Our hot rolled shipbuilding steel is produced
in accordance with the relevant Classification Society, examples of
which include Lloyds Register and Det Norske Veritas.
Our steel products include steel shipbuilding plate, fabricated
steel sections and floor plate for decking. We can also supply bulb
flats for plate stiffening, structural steel angles and inverted
angles.
Our plates are supplied under the ASTM/ASME specification (ASTM
A131 / ASME SA 131) which is the standard specification for
Structural Steel for Ships. We offer higher strength shipbuilding
steels as standard .High strength steels offer significant cost
advantages by reducing the weight of the structure in comparison to
the steel used.
The plates are suitable for use in the construction of container
ships and large cargo freighters as well as commercial shipping
lines such as luxury cruise ships and ferries. Supply options
include heavy plates, surface treated plates and pre-fabricated
sections. In most cases, the steel can also be supplied as hot
rolled coils or cut into lengths (sheets).
These high yield materials are commonly used in the construction of
hulls and superstructures for large shipping vessels. The grades
are exclusively for shipbuilding use as set out in the standard.
