MARKET FORMS OF STEEL

THE STEEL AVAILABLE IN THE MARKET ARE,
                      
ANGLE SECTION:
                             
                The equal angle sections are available in sizes varying from 20 mm x 20 mm x 3 mm to 200 mm x 200 mm x 25 mm. The corresponding weights per- meter length are respectively 9 N and 736 N. The unequal angle sections are available in sizes varying from 30 mm x 20 mm x 3 mm to 200 mm x 150 mm x 18 mm.
                 The angle sections may be of equal legs or unequal legs The angle sections are extensively used in the structural steelwork especially in the in the construction of steel roof trusses and filler joist floors.

CHANNEL SECTIONS:
                                        


The channel sections consist of a web with two equal flanges as shown in fig. 11-5. A channel section is designated by the height of web and width of flange. These sections are available in sizes varying from 100 mm x 45 mm to 400 mm x 100



 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 corrugated sheets are usually galvanized and they are referred to as the galvanized iron sheets or G.I. sheets.


 Expanded Metal:
                                      

It is prepared from sheets of mild steel which are machine cut and drawn out or expanded. A diamond mesh appearance is thus formed throughout the whole area of the sheet. ADVERTISEMENTS: The expanded metal is widely used for reinforcing concrete in foundations, roads, floors, bridges, etc.

T-SECTION:
                                

T-section of size 100 mm X 100 mm x 10 mm with weight per meter length as 150 N. The special T-sections with unequal sides, bulbs at the bottom edge of web, etc. are also available. These sections are widely used as members of the steel roof trusses and to form built-up sections.

I-SECTION:
                                  

I section consist of two flanges and a connecting web • It is designated by – overall depth – width of flange and – weight per meter length. They are available in various sizes from 75mm x 50mmx at 61 N/m to 600mm x 210mm at 995N/m.

                                                                                                                                -suman

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.
