Shs / Rhs pipes
SHS (Square Hollow Section) and RHS (Rectangular Hollow Section) pipes are structural steel profiles with right angles. They are commonly used in construction for their strength and versatility.
technical specification
Sizes
SHS (Square Hollow Section) and RHS (Rectangular Hollow Section) pipes come in various sizes, ranging from small dimensions like 20x20mm to larger ones exceeding 200x100mm, depending on structural requirements.
In India, SHS and RHS profiles are typically manufactured to conform to standards set by the Bureau of Indian Standards (BIS) or other international standards like ASTM (American Society for Testing and Materials). The specific standards may vary based on the application and the steel grade, but commonly used standards include:
IS 4923
Indian Standard for Hollow Steel Sections for Structural Use – SHS and RHS profiles.
ASTM A500
American standard for cold-formed welded and seamless carbon steel structural tubing in round and shapes, including square and rectangular.
EN 10219
European standard for cold-formed welded structural hollow sections of non-alloy and fine grain steels.
The choice of standard depends on the project requirements and may vary for different applications and industries. It’s essential to adhere to the relevant standards to ensure the quality and safety of the structural components.
