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.

2. The door of transformer room, power distribution room and capacitor room should open outward. When there is a door between adjacent power distribution rooms, the door should be able to open bidirectionally.
3. Doors and windows that are often opened in each room of the power distribution room should not be directly connected to places with serious acid, alkali, steam, dust and noise.
4. Windows and doors should be provided with measures to prevent rain, snow and small animals from entering.
5. The power distribution room with a length greater than 7m shall be provided with two outlets and shall be arranged at both ends of the distribution room. When more than 60m, an outlet should be added.
1. The high-voltage power distribution room should be equipped with a lighting window that cannot be opened. The window sill should not be less than 1.8m away from the outdoor floor. The low-voltage power distribution room can be equipped with natural lighting windows that can be opened. It is not advisable to open the window on the street side of the power distribution room.
