What is structural steel?
Structural steel is one of the most important materials used in the construction industry. It is extensively used in the construction of high rise buildings, bridges, residential buildings etc. due to its long list of benefits.
Structural steel contains carbon content in various percentages depending on how it will be used. Increasing the amount of carbon can result in materials with high strength and low ductility. The most commonly used structural steel in construction is the mild steel or low carbon steel. It usually contains 0.05 to 0.3 percent carbon which makes it strong yet less ductile compared to medium or high-carbon steel.
Structural steel fabrication
Structural steel fabrication is the process of turning raw steel into a steel product that is useful for construction. In other words, it is the process of cutting, folding, shaping, bending and assembling steel to create various steel structures. These steel structures are then used to construct various buildings, bridges, industrial equipment, tools, stairs etc.
Properties of structural steel
Structural steel is characterised by a high second moment of area, also known as the moment of inertia which means that it is stiffer than other steels, or less likely to bend.
It can often add greatly to the strength and reliability of a construction project. These steel components can bear significant loads and weigh less than alternative materials. This is partly due to the standard shapes that structural steels are cast into: H beams and C sections, for example, are designed such that performance to weight ratio is maximised. Another reason for the high performance of structural steel is the preparation process – iron is alloyed with carbon and other elements and heat treated for strength.
The use of structural steels, demands expertise in order to inspire confidence in the structure being built, to accurately calculate loads, and to therefore be able to choose appropriate safety margins. This is true for the choice of structural steel material and shape, and additionally for the erection of the steel structure. The erection of the steel structure requires expertise, since (for example) welded joints can become the weakest part of a structure, and rivets can experience higher than usual shear stresses. To safeguard construction workers and end users, it is essential that a reliable manufacturer of structural steel is consulted. They should have thorough knowledge and enough experience in projects similar to yours.
