ARCHITECTURALLY EXPOSED STRUCTURAL STEEL CATEGORY-4

WHAT'S AESS 4?

AESS 4-  SHOWCASE ELEMENTS
AESS 4 focuses on the sculptural nature of the steel. Suitable for “showcase or dominant” elements – used where the designer intends that the form is the only feature showing in an element.
                             
CHARACTERISTICS:
  • All welds are ground and filled edges are ground square and true.
  • All surfaces are sanded/filled.
  • Tolerances of fabricated forms are more stringent
  • All surfaces to be “glove” smooth.

FABRICATION AND ERECTION OF AESS 4:
  • Contouring and blending of welds-to have a smooth seamless finish
  • Minimize Weld Show Through- to avoid distortion.
  • Open holes shall be filled with weld metal or body filler- Where holes must be cut in the web at the interSection with flanges on W shapes and structural tees to permit field welding of the flanges, they shall be filled with joint filler.
QUALITY OF FINISH:

The smooth and contoured appearance of welds enhances the style of the more plastic look of AESS 4 components. This higher level of care and detail allows for glossy coats on steel to be a truly successful aesthetic in close view range.

DISADVANTAGE:

  • More labor and time is often necessary during fabrication and erection to achieve the quality of AESS 4 compared to other categories. 
  • Fabrication and finishes of AESS 4 is costly
  • skilled laborers and specialized engineers required.

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...

BLOG- 8                                     STEEL , ALLOYS AND THEIR COMPARISON                                                               STEEL AND ALLOYS                                               An alloy is a blend consisting of metal and other elements. 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.
