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.

This year, to speed up the construction of national auto and auto parts export bases, it will focus on improving the technical equipment level and product quality of key parts and components companies, improve the local parts supporting industry chain, and establish a component system for high-end passenger cars. Formed a modern automotive industry cluster that has begun to take shape. Data show that from January to July, the gross industrial output value of autos and parts enterprises above designated size was 81.7 billion yuan, an increase of 11.7% over the same period of last year, and the output was 1.032 million, accounting for 8.4% of the country's total automobile output.
The automotive industry is one of the three pillar industries and one of the fastest growing industries. With the acceleration of the global economic integration process, the opening degree of the domestic auto and auto parts market will further expand, more foreign-funded enterprises will enter the Chinese auto market, the market competition will become more fierce, and the competition mode of the auto and auto parts market will be inevitable. There will be great changes. It is understood that the auto parts industry is driven by vehicle companies, the industrial chain has basically been formed, and the agglomeration effect of the industry has become apparent. There are more than 400 auto parts manufacturers in the city and a complete system of micro auto parts other than steering systems, lamps, and tires has been formed. The local matching rate of micro cars is close to 60%; the local supporting rate of medium and heavy trucks At around 30%, parts such as axles, frames, body stampings, body trims, seats, carriages, etc., have strong supporting capabilities.
"Accelerating structural adjustment and strengthening transformation and upgrading." This is the general idea for the development of a new type of industrialization in the region's industrial development conference. It is no exception for the auto parts industry. Recently, the introduction of the project and the construction of the infrastructure of the Hualing Tablet Industrial Park in Liuzhou Automobile City in Guangxi Province have been carried out in an orderly manner. A modern automobile parts industrial park has taken shape. It is understood that the Hualing Tablet Parts Industrial Park covers an area of ​​910.58 hectares, highlighting the distinctive features of the modern industrial system of Liuzhou Automobile City in Guangxi, namely high, new, specialized, refined, and sharp.
The park actively introduced a series of major projects such as the Wuling Group's annual production capacity of 700,000 sets of passenger car parts and components, FAW Liute commercial vehicle base, the National Automobile Quality Supervision and Inspection Center, and the China-EU Cooperation Industrial Park, ensuring the advanced world of the automobile city from the industrial chain. The domestic first-class modernization level. At present, there are 3 batches of 18 companies that have settled in the park and settled on the site. Among the 10 companies to be introduced in the 4th and 5th batch, 8 companies have also passed the accreditation.
According to the relevant person in charge of the City's Industry and Information Technology Committee, driven by the development of vehicle companies, parts and components companies have developed rapidly and a number of highly competitive parts and components manufacturers have emerged. Currently owns a number of backbone parts companies such as Wuling Liuji and Fangsheng Industry. These enterprises have strong capabilities in product quality and cost control, and have the ability to radiate to the surrounding supporting markets. At present, we are making efforts to upgrade the technical level of parts and components companies, and strive to increase the proportion of the total output value of the auto parts industry in the entire industry to over 48% by 2015. The product performance and quality of key auto parts will reach or approach that of similar foreign products. Level, forming a number of well-known product brands.
