Indian Hollow Sections
Indian Hollow Sections are structural steel profiles manufactured with a hollow internal section. Their closed-profile geometry provides a practical combination of strength, rigidity and structural efficiency, making them suitable for a wide range of structural and fabrication applications.
Indian Hollow Sections are commonly classified into Square Hollow Sections (SHS), Rectangular Hollow Sections (RHS), and Circular Hollow Sections (CHS). Each profile offers different dimensional and structural characteristics and can be selected according to the requirements of the application and engineering design.
SHS and RHS are widely considered for steel frameworks, building structures, industrial sheds, platforms, supports, frames and fabricated assemblies, while CHS can be used in structural frameworks, tubular structures, supports and other engineering applications.
At Moksh Tubes & Fittings LLP, we support Indian Hollow Section requirements based on the customer's required profile, outside dimensions, wall thickness, material grade, length, quantity and applicable Indian Standard.
Indian Hollow Sections can also be combined with structural angles, channels, beams and columns to create complete steel frameworks and fabricated structural assemblies.
For an accurate quotation, customers can provide their required hollow section type, dimensions, wall thickness, grade, length, quantity and applicable standard, along with project drawings or technical specifications where required.
