Custom Structural Steel Is Economical and Faster to Install

Structural steel can create a huge reduction in the overall cost by the accumulation of savings in logistics, construction time, equipment cost, labor cost, and material cost.

Cost comparison studies has found structural steel to be 18% cheaper than reinforced concrete when constructing a building frame and 6% lower in terms of total building cost.

They also have the potential to reduce construction time significantly because of high precision of measurements, bolted connections which can be done by hand tools, and production which can be completed in parallel with foundation works schedule. Construction duration of Structural Steel Buildings (SSB) or Pre-Engineered Steel Buildings (PEB) are about 10% shorter compared to conventional structures.

Custom Structural Steel Is Lightweight and Safe

Structural steel building can be 30% lighter than conventional building when properly designed and constructed. This is a factor that can greatly reduce the costs of foundation works and the overall degree of construction difficulties.

During construction, the structure can also be completed more safely due to limitations in volume of equipment & workers involved, scope of hazardous works, and time of exposure to daily risks.

Furthermore, steel is non-combustible. It does not ignite nor spread flames. It is also  resistant to rust and corrosion when properly coated or jacketed, it does not mold or mildew, and resists splintering and shattering during extreme movement.

Custom Structural Steel have Pleasing Appearance and High Quality

Structural steel is visually attractive. Many architects and designers prefer to expose structural steel elements rather than conceal them with other materials. Steel also pairs nicely with other modern architectural elements like glass and fiber concrete.

Structural steel can also be fabricated into numerous shapes or geometrical configurations such as arches, twisted sections, splines, and more. Structural steel is naturally the expression of minimalist and modern architectural designs.

High quality of fabricated and manufactured structural steel can be assured due to production of all components in highly regulated, controlled, and automated environment. All steel units are precisely formed to shapes, sharp edges, dimensions, and required interconnection integrity.

Custom Structural Steel Is Strong and Durable

                                                   

Steel is an excellent tensile and compressive material. Its ability to bend without easily cracking or breaking are inherent advantages of structural steel. Compared to all other materials, structural steel has the greatest ability to maintain strength and integrity during extreme events.

Being lightweight, structural steel are found to react positively to the said extremities such as strong winds. Besides, structural steel has been favored by Engineers for multi-storey buildings especially in areas with high seismic activities like Japan.

Custom Structural Steel Allows Flexible Designs

Aside from all of the benefits and reasons why you should use structural steel while building your home, it also offers you design freedom.

Architects may go beyond the box, developing ideas for homes that are distinct and distinct from the other homes on the block. With your design, you may transform your home into a work of art.

 

Steel Is a Sustainable and Green Material

Being 98% recyclable, steel is the most recycled material in the planet and has low carbon footprints. It is highly regarded as a green building material due to its capability to reduce wastes and pollution by significant numbers.

Steel is one of the most sustainable materials in the world because it loses none of its strength or other physical properties even after repeated recycling. Deteriorated steel and steel scraps can be melted and formed into desired forms endlessly. Demolished but sound structural members can also be transferred, re-used, or re-configured.

Additionally, steel-making process has a 95 percent water recycling rate with no external discharge making the operation conservative and environmental-friendly.

Structured steel is a category of steel used to create construction materials formed into different configurations, depending on how it’s used. Think of it as the backbone of your construction projects, for it’s incredibly versatile and reliable.

Iron and carbon are two of the main elements of structured steel. The more carbon is added, the greater the strength of the steel. Other chemicals are also added to enhance strength, improve the economics of use and deliver less or more ductility.

Uses of Structural Steel

One of the most important resources in the construction industry is structured steel. Below are its common uses:

Bridges – With thousands or millions of cars passing over bridges, the material used in its construction must withstand pressure stress. One of structured steel’s biggest benefits is that it can be created to significantly improve strength so that it serves its purpose.

Steel Girders, Box Girders, H Girders, Truss Girders, Pipe Arch Girders, Bailey bridge, accessories and other miscellaneous items for bridge construction.

High-Rise Buildings – Structural steel can incredibly resist wind, earthquakes, or other natural disasters because of its strength and flexibility. They will not break under extreme pressure. Also, when building high-rise structures, it’s entirely possible to speed up the construction process with steel.

Industrial Buildings – Structured steel is designed to have a high strength-to-weight ratio and is highly durable. They are also cost-effective, and the pre-made parts are easily assembled. These two factors made structural steel suitable material for industrial structures.

Industrial workshop plants, Processing plants, Power plants

Residential Buildings – Using light gauge steel in residential buildings ensures the structure will last for several years. Also, the flexibility in the structured steel makes them the best material for residential buildings situated near the coast or earthquake faults.

Commercial towers and Public Building– Structural steel is ideal for this type of construction because of its track record of delivering cost-effective and high-quality structures. Structural steel can withstand extreme weather conditions such as rainstorms, hurricanes and earthquakes. They are also adjustable and very flexible.

Depending on the design of the building, the panels can be altered to fit various size requirements. Its versatility allows for more expansion compared to traditionally constructed buildings.

Shopping center, airport terminal, railway station, stadium, museum, art center, theme park etc.

Port Structures and Marine Works – Steel is suitable for port infrastructure and marine structures especially in high design loads however it may corrode when exposed to oxygen and salt water. But it can be minimized so long as there is a planned maintenance system. Also, it’s preferred in these types of structure compared to reinforced concrete due to high labor associated in concrete structure.

Hydro Power & Wind Farm – Steel is required in these types of construction. Without it, it would not be possible to create a renewable energy source such as wind turbine or hydro power. It plays a crucial role in all renewables especially wind and solar — both require tons of steel.

Penstocks, water gate, trash racks, Pile legs, towers, foundation embedment

Modules & Offshore Platforms – Offshore structures, large oil ducts and drilling structures are made of steel. The usual method is fusion welding where the joining material is the same as the base material.

Marine structure module, processing module, floating module, subsea modules, platforms, risers and jackets.

Steel Structure Fabrication

Fabricating steel is a complex process and should be handled correctly as there are risks involved. Your project’s long-term viability may be compromised when the structured steel doesn’t meet industry standards for composition and tolerances. In the US, steel grades are regulated by ASTM International. It’s crucial that you hire third-party fabricators as they strictly adhere to industry standards.

The fabrication process involves cutting the structural steel, bending, and assembling them. Welding to combine the structures together is also crucial to making the material stronger. The ability to mold and bend steel into a variety of shapes and sections make them the most versatile and cost-effective construction material. It’s also 100 percent recyclable, making them the most sustainable option.

                  

However, it’s essential that you hire the right fabricator. We suggest that you go with third-party steel fabricators as they have more experience and are incredibly competent are fabricating them.

Principle

Construction materials of different properties are combined to interact and respond against loads in synchronization rather than individually. These composite materials are physically connected to utilize their distinct strengths and features to form a single unit stronger than any separate parts.

Steel-Concrete Composite Construction is meant to achieve efficient and lightweight structural solutions for construction and other related industries.

Background

This engineering and construction method has been widely practiced over a century ago, more dominantly involving the steel-concrete connection. Concrete-encased steel sections were initially developed as composites with the purpose of overcoming the effects of fire while ensuring stability against axial and bending forces.

Composite columns with reinforced concrete core and steel pipe or steel tubular shell were introduced to provide an integral and permanent formwork. Profiled galvanized metal sheets were also introduced to eliminate traditional formworks and at the same time, increasing the strength of reinforced concrete slabs.

Standards

• Design of composite beams and composite slabs for buildings are covered by BS EN 1994-1-1
• Design of Composite Steel and Concrete Structures are covered by BS EN 1990-1999 Eurocode 4
• Australian Bridge Design Code, Section 6: Steel and composite construction
• BS 5400 British Standard code of practice for the design and construction of steel, concrete and composite bridges
• ASHTO: Standard Specifications for Highway Bridges; 24 CFR 200 Sub-part S
• Concrete Slab Stresses in Partial Composite Beams and Girders, American Institute of Steel Construction, Vol. 21

   

Applications

Composite construction is extensively used in bridges, multistorey buildings, warehouses, marine structures, and more. Many applications in the mentioned structures are categorized as beams & girders, floor systems, and column systems.

Composite Beams and Girders. Composite beam includes a steel section in I or W shape attached to a concrete slab by shear connectors atop of it. They have been recognized as one of the most economical structural systems for both multistorey buildings and bridges. 

Obviously, building and bridge floors should be stiff and massive enough to reduce deflection and vibrations. In this case, reinforced concrete is undoubtedly the material of choice. The supporting beam or girder, however should have a superior strength-weight ratio, a quality that only steel can offer. 

Composite Floor Systems. Composite floor system consists of steel beams, profiled metal decking, and reinforced concrete slab. These materials are combined in a compact and very efficient way to form a profile that is basically designed to hold gravity or dead loads as well as traffic loads.

Composite floor systems are mostly used as bridge decks and floor slab for wide range of building classifications largely for elevated car parks and multistorey commercial buildings

Composite Column Systems. Composite columns can either be concrete-filled steel tube or concrete-encased steel element. Either way, composite columns are advantageous as follows

• Flexural resistance of steel pipe or tube is maximized when provided with concrete infill
• Steel casing prevents spalling and confines the concrete.
• Concrete infill delays local buckling of the steel casing and enhances compression resistance
• Steel casement replaces formwork and reinforcing steel

Advantages

The success and versatility of composite construction can be stated in a simple and straight forward explanation – concrete responds excellently in compression and steel behaves the same in tension.

Joining the two materials together as a structure, these strengths can be used to achieve a highly efficient and lightweight design that can effectively resist both axial and flexural forces. Other benefits and advantages are as follows:

• Composite systems are over 25% lighter than concrete construction. As a result, site erection and installation are easier, and labor costs can be minimized.
• Steel-concrete composite can have high strength from a relatively small cross-sectional area.
• The reduced weight of composite itself reduces the forces in those elements supporting them. In this way, supporting members including foundation costs can also be reduced.
• Superior strength-to-weight ratio of composite materials allows compact designs which are expected to be aesthetical, economical, safe, and green.
• Composite systems eliminate the costly activities of traditional concrete forming like propping, stripping, and other temporary works.
• Steel and concrete can be arranged to produce an ideal combination of strength according to calculated requirements.
• Concrete-encased steel elements has good resistance to buckling, fire, and corrosion.
• Composite beams can cover longer spans without the need of intermediate columns, thanks to steel.
• Composite columns reduce the requirement of lateral reinforcement and time-consuming fixing of lateral ties, as well as providing easier connection to steel beams of a steel-framed structure.
• Composite columns involving steel tube or pipe casing simplifies foundation works and construction in bodies of water.
• In marine construction, pouring of concrete under water is made possible by applying composites. Driven steel pipes and sheet piles serves as integral and permanent formworks for concrete infill.
• Concreting of succeeding floors may proceed without having to wait for the previously cast floors to gain strength. The steel decking system provides positive moment reinforcement for the composite floor, requiring only small amounts of temperature bars to control cracking.

Summary

The benefits of combined steel-concrete construction are characterized by three major aspects: speed, performance, and value.

• Steel-concrete composite is about 30% lighter than reinforced concrete and slightly heavier than structural steel by 2%. This significant reduction in weight of composite materials compared to reinforced concrete along with the elimination of huge amount of false works contributes to a huge factor in reducing construction timelines.
• With concrete being strong in compression and steel in tension, the combination of the two materials has proven and excellent results in enhancing the structural performance of the product composite unit. Application of steel-concrete composite can increase the maximum shear strength of a floor slab by 85% according to the results of a study by ASCE.
• Overall savings using steel-concrete composite can be as high as 10% compared to reinforced concrete and 7% when compared to structural steel. Steel encased with concrete does not only improve the strength of the composite members but protect the entire structure from adverse effects of fire, calamities, and corrosion.
