S235JRH

ท่อเหล็กทรงสี่เหลี่ยม/สี่เหลี่ยมกลวง S235JRH จึงเป็นท่อกลวง, ท่อสี่เหลี่ยมหรือสี่เหลี่ยมทำจากเหล็กเกรด S235JRH.

Here are some key features of a typical S235JRH Hollow Section Steel Pipe:

S235JRH Hollow Section Rectangular/Square Steel Pipe

• วัสดุ: S235JRH grade steel, a structural steel grade that offers lower yield strength than S355JR, but still has good machinability and weldability. It’s often used in structural applications where lower strength is acceptable.
• รูปร่าง: Hollow, with a rectangular or square cross-section. These shapes are often used where strong resistance to torsion is required.
• ขนาด: Sizes can vary greatly depending on the application. Common sizes for the square pipes range from 20x20mm to 500x500mm, while the rectangular pipes might range from 40x20mm to 400x200mm.
• ความหนาของผนัง: This can also vary greatly, but common thicknesses might range from 1.5mm to 20mm.
• การรักษาพื้นผิว: Pipes can be treated in a variety of ways to protect against การกร่อน, improve appearance, or enhance mechanical properties. Common surface treatments include painting, ชุบสังกะสี, or oiling.
• มาตรฐาน: Compliance to certain standards depending on the region such as EN 10219- S235JRH in Europe, ASTM A500 in USA or IS 4923 in India.
