In which the first number is height, the second one is width, and the third one is thickness (all in inch) In AISC regulations, the naming used for square and rectangular HSS is as follows: Additionally, hollow sections could also be used for ventilation, heating and cooling. Additionally, the closed shape without any sharp corners in these sections protects them against corrosion.Īnother unique feature of HSS is optimal use of their empty space for instance, filling it with concrete results in increasing their resistance against fire and also results in increasing their tolerance against pressure loads.
Also, compared to the open structural sections, HSS has lower weight and surface. Many examples in the nature display the excellent features of hollow sections against axial, flexural and torsional loads these features along with diverse shapes have resulted in the beauty of architecture. Architects call these sections the 21th century material due to its unique features. During the recent years, due to the visual and mechanical features, the use of these sections has significantly increased. These sections can be square, rectangular and circular and they are used for constructing bridges, stadiums, shopping centers and also residential units. HSS is a tubular section produced by the use of cold form method. Structural Steel Projects such as airports, stadiums, and bridges.Hollow structural sections (HSS) are metal profiles with hollow tubular cross section.Excellent quality Round Hollow Sections are also suitable to use in applications at low temperatures. With consistent mechanical properties, these hollow sections have the strength and excellent surface finishing. These sections are widely used in various mechanical, structural, and construction areas because of many features. Round Hollow Sections have qualities like lightweight, durable, and convenient to use in high-pressure applications. These sections can be made in any suitable material as per the demand of industries. These Round Hollow Sections are suitable to use in various applications in mechanical engineering as well as in the building industry. These sections are made by rolling steel sheet and a slit coil. These are one of the common types of steel sections which are widely used in a variety of formats in different industries. Round or Circular Hollow Section are also recognized as round steel tubes. These sections are available in a wide range of dimensions.It is cost-effective and perfect to use in large industrial projects.Square Hollow Section is easy to bend and hence easy to handle.Square Hollow Section has an excellent weight-to-strength ratio.The uniformity of these hollow sections makes it ideal to use and also make it visually appealing.
Flat surfaces make it inexpensive and convenient to joints.Perfect for post applications as compared to different structural sections.
These sections are readily available in many dimensions and specifications. Square Hollow Section has excellent surface finishing and available in many materials as per the requirements of industries. These sections require minimal edge arrangement while joining and welding. This type of hallow section can be cut in the straight format while joining other flat surfaces. Square Hollow Section has equal-sided symmetry, which makes it appreciative demand and also making it efficient for joining and other manufacturing processes. Square Hollow Section is usually utilized in structural and mechanical applications when a balance is needed between strength and functionality.
