What Services Gnee Provide?

Gnee can provide the following measurement services for DNV Steel:

1. Dimensional measurement: Measure the dimensional parameters such as length, width and thickness by measuring instruments to ensure that the steel plate is qualified and meets the design requirements.
2. Surface measurement: Measure parameters such as flatness, unevenness and surface roughness of the steel plate surface to help ensure that the quality and surface state of the steel plate meet the requirements.
3. Thickness measurement: Use a thickness measuring instrument to accurately measure the thickness of the steel plate to ensure that it meets the design requirements.
4. Material measurement: use material analysis instruments to measure the chemical composition and mechanical properties of the steel plate to ensure that the quality and performance of the steel plate meet the requirements.
5. Bending and Deformation Measurements: During shipbuilding, steel plates may undergo bending and deformation. The degree of bending and deformation of the steel plate is measured and monitored by using tools such as bending measuring instruments and displacement sensors to ensure that it is within the allowable range.

Ask Measurement service

Gnee can customize the size and shape of steel plates for your marine project according to your specific project needs. The custom design of the steel plate is carried out by a professional engineer and design team. Based on the requirements and constraints of the project, they will use calculation and simulation tools, combined with experience and technical knowledge, to optimize the steel plate design to meet the specific needs of your offshore engineering.

● According to the load calculation and strength requirements of structural design, adjust the thickness, width and length of shipbuilding steel plates
● The shape of the steel plate can be designed according to the characteristics of the marine environment. For example, in order to reduce the impact of waves on the structure, the shape of the steel plate can be spherical or flat.
● If you consider the convenience of installation and maintenance, we can also add openings and passages for easy access and operation in the design for areas that require frequent maintenance.

Ask Customized Services

Purchasing Gnee DNV steel plate can provide the following deep processing services. We can customize according to the specific needs of customers to meet the requirements of different ship engineering.

Cutting service: Shipbuilding steel plates can be custom cut to obtain the desired shape and size according to the needs of customers. For example, flame cutting, plasma cutting, laser cutting, etc., can cut steel plates into required plates, blocks, special-shaped parts, etc.
Bending and forming: Shipbuilding steel plates are bent and formed by stress application and appropriate processes to obtain the desired shape.
Welding services: Shipbuilding steel plates can be subjected to various types of welding services, including manual arc welding, gas shielded welding, laser welding, etc.
Turning and machining of holes: Turning and machining of holes in shipbuilding steel plates by using machining equipment. These processes produce smooth surfaces, precise holes and threads to meet specific assembly requirements.
Surface treatment: In order to improve the corrosion resistance and aesthetics of the steel plate, surface treatment can be carried out. This includes methods such as spraying, hot-dip galvanizing, electroplating, etc. to add a protective layer and provide corrosion resistance.

Ask Deep Processing Services

Gnee DNV steel plate can provide the following testing services through third-party testing agencies. These third-party testing services can provide independent, objective verification that shipbuilding steel plates comply with relevant standards and regulations.

Material chemical composition analysis: Through chemical composition analysis, determine whether the composition of the shipbuilding steel plate meets the standard requirements.
Mechanical performance test: mechanical performance test includes tensile test, impact test, bending test, etc., which are used to determine whether the mechanical properties such as strength, toughness and ductility of shipbuilding steel plate meet the specified requirements.
Metallographic testing: Through metallographic testing, check the structure, grain size, non-metallic inclusions, etc. of shipbuilding steel plates to evaluate their quality and performance.
Corrosion performance test: Through the corrosion performance test, evaluate the corrosion resistance of shipbuilding steel plates, including salt spray corrosion resistance, chemical corrosion resistance, etc.
Hardness test: Hardness test is used to measure the hardness of shipbuilding steel plate, and its strength and wear resistance can be evaluated according to the hardness value.
Ultrasonic flaw detection: Ultrasonic flaw detection is used to detect internal defects of shipbuilding steel plates, such as cracks, pores, inclusions, etc.
