Bulk carriers require a wide range of auxiliary structural components beyond the main hull structure. Q235 steel is commonly used in these secondary systems, including ladders, handrails, platforms, cable trays, and access supports.
These components do not carry extreme loads but must maintain durability and structural reliability throughout vessel operation. Q235 steel provides a balanced combination of strength and workability suitable for these requirements.
Shipyards benefit from its excellent fabrication performance. Q235 can be cut, bent, and welded into complex shapes, allowing engineers to customize auxiliary structures according to different vessel designs without increasing production difficulty.
In marine environments, corrosion resistance is an important consideration. Q235 components are typically protected through painting systems or galvanizing to ensure long-term performance under salt exposure.From a material strategy perspective, shipbuilders often use Q235 for non-critical parts while reserving higher-grade steels for hull plating and primary structures. This improves overall cost efficiency without compromising vessel safety.
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.
