How weather conditions affect steel?


Steel is there in almost every building around us. Steel is famous for its strength and durability. But many of us still have a lot of doubts about how the weather may affect steel while we consider construction. 


Let us start with the rain. Rain may result in the steel body having contact with water. If metal and water come in contact, they can result in rust. Rust may become a problem for the user. In recent times, gutters are added to the steel buildings to prevent rust. We can also divert away from the water from the building in this case.  But in most of the cases, rain can come along with lightning. Now lightning may also get attracted to metals. This may give us doubts about why many people prefer steel buildings even after this. But this is where the design of the building plays a major role. It can disperse the heat and electricity of the strike to the ground. So there won't be any harm to anyone inside the building. So even though steel gets attracted to lightning, there won't be any problems inside the house.


Sometimes there can be some extreme weather conditions. The steel building can survive that too without any problem as they get designed in such a manner. They will never bend even in the greatest of pressure. Let us take snow for example. Even though India is not much adapted to snow. Many other countries around the globe have quite a lot of snow across the year. Snow may cause damage to your steel building. But for that, the roof plays an important role. The design of the roof may help in removing the snow. 


So what may happen in high temperatures that are common in our places?  High temperatures can deform the steel as it may lose bearing capacity. They can also cause degradations in the grain structure of the steel. This may be a big problem for the hardness of steel. But the temperature at which steel weakens is very high about 450 degrees celsius. So that is not a problem for us.


These are reactions to different climates by construction material "steel".

Steel Erection, Fabrication and Hybrid construction -Blog 16

Image
This blog is about how the steel sections are transported to the site, the issues involved with transportation, erection and fabrication along with the onsite constrains. TRANSPORTATION: The steel sections have to transported from the manufacturing site to the fabrication site and this becomes a tough task due to their size. Often large pieces cannot be transported in a single part, they are split or divided and shipped as two separate pieces or even as one piece to avoid damage or scratches. Temporary connections are made on the pieces to avoid damage and to keep the parts in place during transportation.     These parts are not transported in normal vehicles but require long trail vehicles to fit their length and size which again becomes a difficult task to turn around the corners of the road and at junctions     FABRICATION & ON SITE CONSTRAINS: Fabrication of steel on sites which are along the main road or at the corner site is very hectic as there is very...

BLOG-16 FABRICATION, ERECTION AND HYBRID STRUCTURES

Image
  FABRICATION: The process of  steel fabrication  involves grinding, welding, cutting, bending, drilling, punching, burning or melting and other general crafting methods using various high-quality tools and CNC equipment. ERECTION LIFTING, POSITIONING AND PLACING OF STEEL MEMBERS IN A STRUCTURE  Once the member(s) are lifted and placed in the required place, with the help of temporary supports and equipment, they are fastened and fixed, depending on the nature of connection.  Erections may be achieved by two techniques such as MEWP(Mobile Elevating Work Platforms) by Mobile crane and Tower cranes. HYBRID STRUCTURES Hybrid structures are structures built with composite materials a combination of different materials with steel. A common  hybrid system  consists of hollow core slabs together with steel or cast-in-situ concrete frames                       EXAMPLE STEEL WITH TIMBER     I...

Alloys are generally made for achieving properties like greater strength or resistance to corrosion. Steel is an alloy of iron. It mainly consists of iron with some small amounts of carbon.
