Hot-Pressed Rolled Steel Angle Beams

RSA-E (Equal)

The legs on an RSA-E steel beam are the same length and form a right angle.  RSA-E steel beams are often used for brackets in cleat connections, as well as for lintels (two angles bolted back-to-back) in balconies, platforms, stairs, and concrete supports.

RSA-U (Unequal)

The legs on an RSA-U steel beam are not the same length, forming a right angle. When describing RSA-U beam dimensions, the longer leg is given first.

With the longer leg in a vertical position, RSA-U beams feature greater loading capabilities than RSA-E beams. RSA-U is, similar to RSA-E, optimal for use in cleat connections as brackets, and for lintels in balconies, platforms, stairs, and concrete supports.

RSA Structural Steel Beam FAQs

Below are the most common questions sent to our team about our RSA structural steel beams.
  • What does RSA Steel Stand For?

    In the structural steel industry, RSA stands for Rolled Steel Angle, which describes a type of steel beam shape. There is also RSA-E and RSA-U, which stand for ‘Equal’ and ‘Unequal’ RSA beams, each.
  • What’s the difference between RSA-E and RSA-U?

    All RSA beams form a right angle between two legs of steel, but the two types make different shapes:
    • RSA-E features equal-length legs, forming a box-like shape
    • RSA-U features legs of different lengths, forming an L-shape
  • What is Hot-Rolled RSA Steel?

    Hot-roll is a method of structural steel fabrication where steel is rolled into shape at incredibly high temperatures. This allows for larger-sized fabrications than usual and has the advantage of naturally cooling after pressing.
  • Can I Have Holes Put In My RSA Beam?

    Yes, STEELO offers bespoke fabrication of RSA steel beams, structures, and connectors, allowing you to customise the dimensions and features of components as necessary.
  • What is a Rolled Steel Angle (RSA) Beam?

    RSA structural steel beams are used primarily for cleats and connections. There are two types of RSA steel beam:
    • RSA-E: Featuring equal-length legs
    • RSA-U: Featuring unequal-length legs
