Erection, fabrication and hybrid construction of steel

 Fabrication use structurally by cutting, forming, machining, bending, welding, and assembling processes by site erections. Fabrication needs skilled labor for transforming raw components to market items. The process of fabrications done in site or factory according to space constrains issues and humanity and requirement. Market steels have assembled in site. The structures or membrane need to be handled carefully while transport to the site.

   Erection is the structural steelwork that happens in a frame on site. The process involves lifting and placing an exact position by connecting together. Connections may be achieved by bolting, welding, and sometimes riveting. erections may be achieved by two techniques such as MEWP(Mobile Elevating Work Platforms) by Mobile crane and Tower cranes. While the erection single part of steel will be shipped to prevent the damage after transport parts have been assembled in site. Weatherproofing does need while shipping steel. Long members or structures cannot be shipped due to road safety and restriction. Long structures and members can be shipped as separate parts. Need skilled labor to handle. Hidden bolts were used to all welded structures to an erection. Using padded supported points so as not to damage the intumescent applied coating. (1)

  Hybrid construction is an innovative technique in construction by combining different materials or techniques in one structure like a combination of steel and wood in a concrete structure. The exterior structure has been prevented by galvanizing coating or other waterproof membranes on it. This type of constructions has done through proper design strategies.  Linked hybrid by Steeven Holls and Brentwood station byBusby associates is a good example of hybrid constructions.

Steel Erection, Fabrication and Hybrid construction -Blog 16

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...

  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.
