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.

The "Notice" pointed out that the development and construction of the monitoring system for overloading and speeding of commercial concrete mixer trucks in Hangzhou is an important measure to implement the scientific concept of development, achieve safe production, ensure the safety of people's lives, and to unify and standardize the commercial concrete in Hangzhou. The enterprise market order is an important measure for the healthy and stable development of the industry. The main network of overload monitoring system for concrete mixers in Hangzhou is under the unified management of Hangzhou Commercial Concrete Management Station.
The "Notice" requires that the company's main responsibility for production safety should be effectively implemented and the safety management of concrete mixer trucks must be strengthened. As the main responsibility of safe transportation management, the enterprise shall actively cooperate with the municipal commercial concrete management station and various district (development zones) and county (city) construction bureaus to install the concrete mixer vehicle overload and speed monitoring system. Concrete enterprise mixer trucks shall timely report the vehicle information such as driving permit copies to the management station system for registration and change before they are put into transportation, rented or have their changes scrapped, and are strictly prohibited from overloading and speeding.
The "Notice" emphasized that in order to severely investigate violations of laws and regulations, the city management station shall dispatch special personnel to supervise the system and supervise the enterprise's overloading and super-rates. It shall be regularly notified within the industry and shall be included in the assessment of the company's market and linkage with the site. If a company violates the requirements of this notice, the municipal management station and the construction administrative department at all levels shall order it to make correction within a time limit; if the traffic safety fatal accident is caused due to overloading and the enterprise bears equal responsibility or more, the enterprise shall be ordered to suspend production for rectification while limiting its concrete supply market behavior.
Hangzhou to strengthen the monitoring of overloading and speeding of concrete mixer trucks
In order to give full play to the role of overloading and speeding monitoring system platform for concrete mixer trucks in Hangzhou, standardize the transportation behavior of the concrete industry and ensure the safety of transportation, the Municipal Construction Bureau issued the Notice on Strengthening the Management of Overloading and Overspeed Monitoring System for Concrete Mixing Trucks in Hangzhou (hereinafter referred to as “ Notice").
