The structure of steel is assembled with various materials of different materials of different shapes and sizes and connected together by bolting or welding or riveting. Also, it acts as structural support for constructions and safely withstands loads for longer.
Furthermore,
any building that uses as building materials is called structure. Before
cladding is added, it is the skeleton of a building. Also, structures are made
of and are the best alternative option for RCC columns and beams. In addition
to this, steel attributes compression strength and tensile strength. Also,
construction of a structure is much faster than concrete as there is no need
for curing time after casting. Today, steel is most widely used building
materials in construction and this happens due to its durable and versatile
feature. Also, it is affordable too. Using structures can be proved to be the
best form over any another in terms of durability and budget friendliness and
it's practicality. No matter what is the nature and size, it is useful. Tall
structures are constructed using this because of its constructability and high
strength to weight ratio as compared to concrete while being less dense than
iron and much lower strength to weight ratio. The key reason behind why steel
is used in many construction projects is its durability.
Steel has the highest strength to weight ratio
in comparison to any other building materials and seems like the most versatile
materials ideal for buildings. Besides, it also consistent as reputed structure
manufacturers follow national standards during its design and production.
Structural steel melts at 2500° F while building fires commonly reach a
temperature in the range of 2000°F. The possibility of melting steel is rare,
but it does not mean that steel structures are safe.
How
to keep steel structure safe from fire
The
most common way of fire proofing is by spraying low density fibres. These
sprays can be applied dry or wet in coating of the desired thickness to provide
heat resistance to steel. But, they are used in wood, fabrics and other
materials.
Intumescent
paint or coatings
They provide fire resistance to steel members and can expand as much as 100 times their original thickness and providing greater resistance by creating a buffer between a steel element and the fire. Also, the coatings will undergo a chemical reaction and expand when exposed to external heat. It can apply like paint and used in steel exposed to the general public.
