Exploring the Different Shapes of Steel Sections and Their Uses
23 October 2023
Steel has long been recognised for its incredible strength and versatility. Acting as the backbone for architectural marvels – from soaring skyscrapers to intricate bridges – the advantages of steel sections are undisputed.
What adds to the supremacy of steel is its versatility. The array of available steel section shapes makes it possible to tailor applications to exact requirements. This article delves into the multifaceted world of steel sections, highlighting their diverse shapes and tailored applications and guiding builders, designers, and consumers to make informed decisions.
Steel Angles
Steel angles, commonly referred to as angle irons, are L-shaped sections, typically having equal or unequal sides. They are produced by rolling pre-heated steel into the desired shape.
Given their inherent strength and bend resistance, steel angles are ideal for frameworks, braces, supports, and even decorative elements like ornate trellises.
Steel Beams / RSJs (Rolled Steel Joists)
Steel beams, often named I-beams due to their resemblance to the letter 'I', are central to construction. RSJs are a subset of steel beams, distinctive by their rolled edges.
These elements serve as the backbone of buildings, bridges, and lofts, providing the necessary structural supports that ensure stability.
Steel Bearing Plates
These flat, sturdy steel sections, usually square or rectangular, are designed to distribute loads uniformly. Essential for distributing loads from beams, columns, and other structural elements, they play a pivotal role in anchoring components and bridging gaps, ensuring smooth and consistent load transfer.
Steel Box Sections
As the name suggests, these are tubular steel sections that can be square or rectangular in shape, providing a hollow yet robust profile.
Owing to their high strength-to-weight ratio, they're used as frameworks, columns, and other pivotal load-bearing structures in construction.
Steel Channels
Steel channels exhibit C-shaped or U-shaped profiles designed by rolling steel into these distinct forms. These profiles are often utilised as supports and guides for building components. They’re also found framing windows, and doors, and serving as conduits.
Steel Flats and Flitch Plates
Steel flats are elongated, thin steel sections, while flitch plates typically combine wood and steel, providing hybrid strength. Their applications range from reinforcements to brackets.Â
Flitch plates, in particular, facilitate connections between wooden and steel beams, merging the benefits of both materials.
Solid Steel Bars
These full-bodied bars can be round, square, or hexagonal, fashioned from solid steel. Their robustness makes them suitable for various construction projects, machinery components, and even decorative purposes.
Spliced Steel Beams
As the term indicates, these are beams crafted by joining two or more sections, creating a longer span. They’re paramount in renovations and areas with transportation constraints, allowing for extended spans.
Twinned Beams
This involves pairing two similar or identical beams, enhancing their combined structural attributes. When a single beam doesn't suffice, twinned beams come into play, amplifying load-bearing capacities, making them ideal for large spans and retrofitting projects.
Conclusion
Understanding the various steel sections and their applications is vital. The right choice ensures safety, structural integrity, and longevity. Being informed allows for optimal results, whether you're a builder, designer, or a consumer.
