Hull block construction is a core process in modern shipbuilding, where large prefabricated sections are assembled before final integration. Q235 steel is widely used in temporary structures such as positioning frames, alignment supports, and reinforcement fixtures during this stage.
These structures ensure accuracy during assembly but are not part of the final vessel. Q235 steel provides the necessary flexibility to fabricate and adjust these systems according to different block sizes.
Its strong weldability allows rapid assembly of temporary steel structures, which is essential in large shipyards where multiple hull blocks are processed simultaneously.
In addition, Q235 steel can be easily machined into plates and profiles, supporting efficient production of temporary reinforcement systems.
Because of its cost advantage, Q235 is widely used for non-permanent structures, helping reduce overall shipbuilding expenses.
These temporary systems are often reused after inspection and maintenance, improving material efficiency across multiple projects.
GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
