Where is S275JR H-shaped steel used in bridge construction?
For bridge pier structure: It can be used as the main supporting material of the bridge pier, using its high strength and stability to bear the weight of the bridge superstructure and loads such as vehicles.
As a bridge deck beam: It can be used to construct the beam structure of the bridge deck. With its good bending resistance, it can bear the deadweight of the bridge deck, the dynamic load generated by the driving of vehicles, etc., so that the bridge deck remains stable.
Make bridge support trusses: It can be welded or bolted into a truss structure, which is used in large-span bridges to improve the spanning capacity of the bridge and reduce the deadweight of the structure.
What are the applications of S275JR H-shaped steel beam in mechanical supports?
Heavy equipment supports: used to support heavy machinery and equipment such as large machine tools, presses, and injection molding machines. For example, the base and column parts of large gantry milling machines are made of S275JR H-shaped steel, which can withstand the weight of the machine tool itself and various forces generated during the processing process, ensuring the accuracy and stability of the machine tool.
Production line conveyor equipment supports: On automated production lines, they are used to support conveyor belts, rollers and other conveying equipment. For example, in the final assembly line of an automobile manufacturing plant, the conveyor belt supports of the conveyor frame often use S275JR H-shaped steel, which can withstand the weight of vehicle parts on the conveyor belt and the impact force during operation, ensuring the smooth operation of the conveying system.
Storage shelf supports: The columns and beams of heavy storage shelves usually use S275JR H-shaped steel, which can withstand the weight of the goods, and can withstand the collision and vibration of equipment such as forklifts during frequent storage and retrieval of goods, ensuring the safety and service life of the shelves.
What is the difference between S275JR beam and S355JR steel in application?
Application scenarios
S275JR H-shaped structural steel is often used in general building structures, such as frame structures of multi-story residential and commercial buildings, which can meet conventional load-bearing requirements and have relatively low costs.
S355JR structural steel is suitable for structures with high strength and stability requirements such as the main beams of high-rise buildings and large bridges. In heavy machinery and equipment, such as the support structure of large mining machinery and metallurgical equipment, S355JR H-shaped steel is often used.
Processing performance
S275JR H-shaped steel beams have good cold bending and welding performance, and are easy to cut, bend, punch and other processing operations. They can meet the processing requirements of general projects and have low construction difficulty.
S355JR H-shaped structural steel beams have good weldability, processability and corrosion resistance, and can meet the processing and use requirements of various high-strength structural parts, but due to their high strength, more advanced equipment and processes may be required during the processing process.
