S355JR is a kind of European standard hot-rolled structural steel, belonging to the low-alloy high-strength structural steel. This type of steel is widely used in the fields of construction, bridges, and ships. For the S355JR high-strength carbon ship/bridge hot-rolled steel plates that have passed the certifications of CCS (China Classification Society), ABS (American Bureau of Shipping), and BV (Bureau Veritas), the specific applications are as follows:

 

Shipbuilding Field:

 

Hull Structure: It can be used for the construction of parts such as the deck, side shell, and bottom of the ship's hull. For example, in ship types like bulk carriers and container ships, these parts need to bear the weight of the cargo, the pressure of seawater, and various dynamic loads during the ship's voyage. The high strength of the S355JR steel plate can meet the force-bearing requirements of these structures.

 

Compartment Structure: Such as the bulkheads of the cargo hold, watertight bulkheads, etc. Watertight bulkheads are of crucial importance to the safety of the ship and need to possess high strength and sealing properties. The S355JR steel plate can ensure the structural integrity of the bulkheads when they are bearing the pressure of the cargo inside the hold and the pressure of seawater.

Strengthening Structures of the Ship: Such as the keel, ribs, and longitudinal girders of the ship's hull. These components are the main supporting parts of the ship's structure and need to bear relatively large stresses. The high-strength characteristics of the S355JR steel plate enable it to provide good structural strength and stability for the ship.

 

Bridge Field:

 

Main Girder of the Bridge: The main girder of a bridge is the main load-bearing component that undertakes the self-weight of the bridge and the vehicle loads. The S355JR steel plate can be used to manufacture the main girder of a steel girder bridge. Its high strength can ensure that the bridge can bear the effects of various loads during its long-term use and has good fatigue resistance, enabling it to adapt to the frequent vehicle traffic on the bridge.
