Market forms of steel                                                                                                  * Angle sections *Channel sections * I- sections * T- sections * Round bars * Square bars *Corrugated sheets * Expanded metal *Flat bars *Plates *Ribbed tor steel bars                                                                                                                                                                         Angle sections                                                                            Angle sections have two legs , If two legs are of equal length then they are known as equal angle section and otherwise called as unequal angle section. It is used in structural steelwork especially in the construction of steel roof trusses.                                                               Channel Sections                                                                                                  The channel sections consist of a web with equal flanges .Channel section is designated by the height of web and width of flange. The Bureau of Indian Standards has classified channel sections as (ISJC) Indian Standard Junior Channel (ISLC) Indian Standard Light Channel (ISMC) Indian Standard Medium Channel (ISSC) Indian Standard Special Channel The channel sections are widely used as the structural members in steel framed structures, crane girders, beams & steel bridge                                                                           I-Sections                                                                                                              Commonly known as Rolled Steel Joist (RSJ) or beams .I section consist of two flanges and a connecting web . The Bureau of Indian Standards has classified the I-sections into junior beams, light beams, medium beams, wide-flange beams and heavy beams and they are accordingly designated as (ISJB), (ISLB),( ISMB), (ISWB), (ISHB)                                      T-sections                                                                                                                     The shape of the section is like that of letter T .it consists of flange and web. It is designated by overall dimensions and thickness .These sections are widely used as members of the steel roof trusses and to form built-up sections.                                                    Round Bars                                                                                                                 These are available in circular cross-sections with diameters varying from 5 mm to 25 mm They are widely used as reinforcement in concrete structures, construction of steel grillwork,                                                                                                                      Square Bars                                                                                           These are available in square cross-section with sides varying from 5 mm to 25 mm. They are widely used in the construction of steel grillwork, for windows, gates.                            Corrugated sheets                                                                                                These are formed by passing steel sheets through grooves. These grooves bend and press steel sheets and corrugations are formed on the sheets. These sheets are used for roof covering.

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.
