In structural steel, there are many prevalent construction materials. If you look at the image above, we are pretty sure that you must have noticed these beams in the structures around you. You might have noticed these beams in the bridges or during construction while walking around. These beams are called “I beam” because of the cross-section shape that looks like the letter ‘I’. So why do construction experts prefer using these I beams during various projects? Here are some of the reasons how I beam benefit during steel construction. As we all know now that I beam is known for its reasonable cross-sectional shape. An I beam is designed in a way to handle a uniform load across the beam. When there is a weight on the beam, the maximum deflection will fall on the centre of the beam. This increases the tension on the sides of the beam. Let’s look at the image to understand how it works:

When the weight is applied on the ■■■■■■, the weight is distributed evenly on it, causing less tension to pass through the web. By the time the weight reaches the center of the web (neutral axis), the weight is reduced to zero due to the distribution of the weight. Therefore, due to the shape of I beam, it can bear the load of weight put on its ■■■■■■. I beams are universal beams and used globally for most steel construction project. It comes in a variety of weights, section depths, web thickness, ■■■■■■ widths, and other specifications for different purposes. Depending on the structure of the I beam, it is used for different purposes. For instance, when you build a bridge with a rectangular cross-section, you might build it for the vehicles to move around. Due to various factors like gravity or the weight of the vehicles moving on the bridge, a large amount of weight is pushed down. As a result of the weight, the bridge can deform due to a lot of stress and might even break. Therefore, to resist the bending, I beams are used to support the structure due to its design. The design of an I beam makes it capable of bending under high stress instead of buckling. As the beam receives the load, the force is transmitted perpendicularly, thus supporting other members of the beams. I beams are mostly made of steel, therefore ensuring structural integrity with relentless strength and support. I beam strength is less formidable in the transverse direction and also adept at carrying torsion. Steel has properties that allow withstanding hefty loads of the structures. The strength of the steel and the shape of the beam both can reduce the need to include numerous support structures, saving time and money and making the structure more stable. The section at the center of the beam, or the neutral axis, does not resist bending due to the uniform distribution of the weight across the beam. Due to the distance between the ■■■■■■ and the axis, I beams have a high moment of inertia. The larger the moment of inertia, the lesser the beam will bend to resist the bending moments. I beams can be rolled, welded, extruded, and riveted as well because of this property. Metal fabrication involves the cutting, bending, and shaping of structural steel. I beams are very versatile and can be used in any steel construction projects. I beam steel fabrication is fast, efficient, and affordable to fulfil the orders and meet the demands of the project. With the right amount of knowledge, experience, hard work, and the use of specialised tools, it is easier to use I beam during custom welding processes and metal fabrication for all types of construction. The production of I beams means minimum waste during construction. There are green practices in different countries making I beam affordable. Almost half of the world’s steel is produced in electric plants to generate no CO2 emissions. Steel products can be recycled over and over again without compromising on their strength. Since I beams are mostly made of steel, they can be recycled and reused in many ways and also reduce costs. Recycling steel saves the equivalent energy to power about millions of households for a year. One of the major challenges while constructing a building is to create a structure with less floor vibration. Floor vibrations in the steel buildings can be created with a variety of direct and indirect sources of vibration. But the three main categories can be:
– Human activity (jumping, walking, and running)
– Machinery and equipment
– External force (traffic on street or underground, or wind)
Since I beams are stiffer and bear higher loads, they are used to reduce the vibration of the floor by supporting the structure. With steel I beam, the vibration is damped quickly before it can travel very far. I beams are an efficient option for steel construction. You may also refer to other types of beams available in the market. Depending on your construction requirement, we recommend you to choose the right type of steel beam and construct a flawless structure.

  • Internal structural ■■■■■■■■■ for instance, rails, shelving, and stairs are also composed of steel.
    Steel offers architects more design freedom in colour, texture and shape. Its combination of strength, durability, beauty, precision and malleability gives architects broader parameters to explore ideas and develop fresh solutions. Steel’s long spanning ability gives rise to large open spaces, free of intermediate columns or load bearing walls. Its capacity to bend to a certain radius, creating segmented curves or free-form combinations for facades, arches or domes sets it apart. Factory-finished to the most exacting specifications under highly controlled conditions, steel’s final outcome is more predictable and repeatable, eliminating the risk of on-site variability. Steel can be assembled quickly and efficiently in all seasons. Components are pre-manufactured off site with minimal on-site labour. A whole frame can be erected in a matter of days rather than weeks, with a corresponding 20% to 40% reduction in construction time relative to on-site construction, depending on a project’s scale. For single dwellings, on more challenging sites, steel often allows less points of contact with the earth, reducing the amount of excavation required. Structural steel’s lighter weight relative to other framing materials such as concrete enables a smaller, simpler foundation. These efficiencies in ■■■■■■■■■ translate to considerable resource efficiencies and economic benefits, including accelerated project schedules, reduced site management costs and an earlier return on investment. These days, a building’s function can change dramatically and rapidly. A tenant may want to make changes that increase floor loads significantly. Walls may need to be repositioned to create new interior layouts based on different needs and space usage. Steel-built structures can cater for such changes. Non-composite steel beams can be made composite with the existing floor slab, cover plates added to the beams for increased strength, beams and girders easily reinforced and supplemented with additional framing or even relocated to support changed loads. Steel framing and floor systems also allow easy access and alterations to existing electrical wiring, computer networking cables and communication systems. Steel sections provide an elegant, cost-effective method of spanning long distances. Extended steel spans can create large, open plan, column free internal spaces, with many clients now demanding column grid spacing over 15 metres. In single storey buildings, rolled beams provide clear spans of over 50 metres. Trussed or lattice construction can extend this to 150 metres. Minimising the number of columns makes it easier to subdivide and customize spaces. Steel-built buildings are often more adaptable, with greater potential for alterations to be made over time, extending the lifetime of the structure. When a steel-framed building is demolished, its components can be reused or circulated into the steel industry’s closed-loop recycling system for melt down and repurposing. Steel can be recycled endlessly without loss of properties. Nothing is wasted. Steel saves on the use of natural raw resources since around 30% of today’s new steel is already being made from recycled steel. Extensive testing of structural steelwork and complete steel structures has provided the industry with a thorough understanding of how steel buildings respond to fire. Advanced design and analysis techniques allow precise specification of fire protection requirements of steel-framed buildings, often resulting in significant reductions in the amount of fire protection required. Earthquakes are unpredictable in terms of magnitude, frequency, duration, and location. Steel is the material of choice for design because it is inherently ductile and flexible. It flexes under extreme loads rather than crushing or crumbling. Many of the beam-to-column connections in a steel building are designed principally to support gravity loads. Yet they also have a considerable capacity to resist lateral loads caused by wind and earthquakes. Steel’s slender framing creates buildings with a sense of openness. Its flexibility and malleability inspire architects to pursue and achieve their aims in terms of exploring distinctive shapes and textures. These aesthetic qualities are complemented by steel’s functional characteristics that include its exceptional spanning ability, dimensional stability over time, its acoustic noise dampening abilities, endless recyclability and the speed and precision in which it is manufactured and assembled onsite with minimal on-site labour. Steel’s ability to maximise space and internal width with the thinnest shell possible means thinner, smaller structural elements are achievable. Steel beam depths are around half that of timber beams, offering greater usable space, less materials and lower costs compared with other materials. Wall thicknesses can be thinner because steel’s strength and excellent spanning capacity means there’s no need to build solid, space-consuming brick walls. This can be particularly relevant for heavily constrained sites, where steel’s space-saving properties can be the key to overcoming spatial challenges.
    Steel structures can be significantly lighter than concrete equivalents and require less extensive foundations, reducing the environmental impact of the build. Less and lighter materials means they are easier to move around, reducing transportation and fuel use. Steel pile foundations, if required, can be extracted and recycled or reused at the end of a building’s life, leaving no waste material on site. Steel is also energy efficient, as heat radiates quickly from steel roofing, creating a cooler home environment in hot climate areas. In cold climates, double steel panel walls can be well insulated to better contain the heat.
