WEATHER CONDITIONS AFFECTING STEEL

 

WEATHER CONDITIONS AFFECTING STEEL

Steel becomes brittle during colder weather conditions due to the presence of more carbon in it. During summer, it expands.

Rusting or corrosion of structural steel is a process that happens due to the presence of moisture or water content in air i.e. humidity. The iron in steel is oxidized to produce rust. The metal corrodes when a chemical reaction takes place involving oxygen and water.

Rusting is less likely to occur if the metal is kept in hot climatic conditions or in a dry place where there’s less moisture content.

On a contradicting note, the metal might rust at a faster rate if the metal is exposed to high heat or during summer when there’s extreme amount of heat generated. Increased humidity leads to increased rust.

In snow regions, the roads are treated with a certain amount of salt and deicing substances are also used simultaneously. Roads that are covered with ice increase the rate of speed of rust formation.

Rains generally increase the rate of corrosion, wherein acid rain caused by pollution and other natural occurrences also take part in this contribution.

The rate of occurrence of rust during acid rain depends mainly on how low the pH level of the water is. The normal level being 5.6

SOLUTION

The surface of the material is to be well prepared or coated with best quality.

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.
