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.

Nylon Insert Lock Nut or nylon lock nut, nyloc nut contains an added nylon ring within the nut that helps lock the nut into place more securely. The most popular used are nylon lock hexagon nuts which compatiable with Hexagon Head Bolts (Hex bolt).
Nylon lock nuts have a small nylon ring at one nut end that forms slightly smaller hole than the threaded hole going through the nut. When the nut is screwed onto a bolt, the bolt has to force its way through the smaller opening, causing the nylon to stretch. This stretching creates a huge amount of friction between the nut and the bolt, allowing the nut to stay tight for long periods of time without coming loose. Nylon lock nuts are especially useful for applications that involve a lot of vibration that would cause regular nuts to come loose.
