Structural Construction- Considering the Dependability and Quality of Steel

Stay Connected

Steel is widely used in the structures of different types of buildings and is associated with a range of benefits. Regardless of what your business or building may be if you are dealing with existing buildings or constructing new buildings, steel is likely to be the preferred option.

The properties of steel are derived from how it is manufactured, processing during fabrication and its chemical composition. The product standards indicate the limits for performance, quality, and composition. These limits are presumed or utilized by designers.

Material Properties

There are a number of key properties that designers are concerned with. When specifying steel products, properties that are typically considered include the following durability, weldability, ductility, toughness, and strength.

Mechanical Properties

  • Mechanical properties result in form minimum values that are specified within the product standard. The alloy chemical content determines weldability while durability is based on the type of alloy.
  • The mechanical properties of steel are derived from a combination of the manufacturing process, heat treatment, and chemical composition. Iron is the major component of steel but adding other elements in small quantities can have a significant effect on the properties of steel. Learn more at
  • Adding alloys like manganese can increase the strength of steel. However, additional alloys can also have a negative effect on properties such as weldability, toughness, and ductility. A careful balance of the chemical composition of every steel specification is necessary during production to make sure that suitable properties can be achieved.


The strength of steel is a property that is commonly considered because it is the basis that is often used for design codes. A number of factors at the stage of specification determine the toughness of steel along with its resistance to brittle fracture. Tests are used for this purpose, including subjecting specimens to impact blows from pendulums at specified temperatures.


Ductility is a factor in different aspects of design that include the fabrication process of straightening, building, and welding. Structural steels are generally weldable but it is important to make sure that specifications for welding procedures are appropriate for the steel grade.


Corrosion prevention is another critical property. Galvanising and painting are the most common ways to provide corrosion protection for construction steel. Design life, location, and degree of exposure are some of the factors that determine the degree and type of coating protection that is required.


Since components are often engineered by the manufacturer, a relatively short period of time is required to erect steel structures. This also makes it possible to put large-scale projects together faster. Pre-engineering further minimizes human error and the time that is required to rectify mistakes.


Steel has drastically dropped in price over time due to production and engineering advancements. It is also cost-effective because construction involves less time in comparison to other conventional materials, which helps to save money. Steel is low-maintenance and less is spent on upkeep.  


Steel is well known for its longevity, especially in comparison to materials like wood. Durability reduces maintenance costs and enables larger open spaces in buildings such as indoor arenas and skyscrapers.
