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.

New industries that have a major impact on the instrumentation industry are low-carbon industries. The low-carbon economy has become a hot spot in the world economy with its unique advantages and huge market, and it is closely related to the instrumentation industry. At the same time, instrumentation has the characteristics of “three highs and three lowsâ€, namely, high technology, high input, high output, low energy consumption, low material consumption, and low pollution. The development of a low carbon economy is bound to drive up the demand for instrumentation.
For example, thermal energy meters and thermal energy meters are energy metering devices that can directly enter home or environmental monitoring departments to monitor carbon dioxide emissions. Their market prospects and market capacity are huge. Another example is automation control instruments, including thermal power grid automation control instruments, CBM power generation automation control instrumentation, smart grid system instrumentation, motor energy-saving instrumentation, energy automation control instrumentation, etc., all of which are becoming more and more important with the construction of smart grids. .
However, the total output value of China's instrumentation industry is low, and the scale of the company is also small, which is not conducive to the transition to the high-end. According to statistics, there are 1,887 large- and small-scale enterprises in the industry, but there are less than 15 companies with annual sales of more than 1 billion yuan, and there is a lack of "flagship" companies with comprehensive strength.
With the exception of a few key enterprises, most companies take the path of low-cost expansion. With the strong cooperation and supporting capabilities formed by specialized division of labor, many products have made the cost very low. It is precisely because of this low cost advantage that they overcome their opponents and seek development. However, this kind of low-cost expansion will affect companies’ sense of urgency for technological investment and talent absorption, and it is also not conducive to industry transformation.
In addition, investment in corporate technology development is generally insufficient. Since most domestic enterprises are small and medium-sized enterprises, they cannot support sufficient and long-term technological innovation in human and financial resources. Taking scientific instruments as an example, the development investment of foreign companies in general accounts for 10% of sales, while China only accounts for 3%.
China's instrumentation industry is facing a rare opportunity for high-end transformation, but before seizing the opportunity, the industry and companies must first consider how to overcome the industry's own shortcomings.
High-end transformation of instrumentation industry needs to overcome industry weaknesses
Since the second half of 2009, the instrumentation market has gradually recovered. The rapid development of emerging industries has driven the instrumentation industry out of the trough; and the progress in intelligent technology has enabled the instrumentation industry to accelerate the transition to high-end manufacturing.
