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 less staging area.

This blog gives an overall view about how steel is cut, the process involved and their types / varieties. It also shows the way in which steel sections are bent and curved. Thank you for reading ! - Theerthana✌ REFERENCE: https://www.custompartnet.com/wu/sheet-metal-shearing

 BLOG -16 FABRICATION, ERECTION AND STRUCTURES    FABRICATION :                            steel fabrication is the process involving the transformation of raw steel into a product or item that can be used in construction or assembly. Steel is considered an alloy of iron and other metals. There are a wide variety of different kinds of steels, which are used in structural and fabrication operations. The basic methods of fabricating include cutting or burning, forming, machining, or welding. ERECTION :                                    The erection of structural steelwork consists of the assembly of steel components into a frame on site. The components are then lifted and placed into position before they are connected together. Generally, connection is achieved through bolting but, in some cases, site welding is used.        HYBRID STRUCTURES :                             Hybrid buildings are becoming increasingly common because they make use of wood, which is a renewable, more eco-cons

 FABRICATION, ERECTION AND HYBRID STRUCTURES FABRICATION: Fabrication is the process used to manufacture steelwork components that will, when assembled and joined, form a complete frame.   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 . The entire steel fabrication process is systematic and requires the utmost planning, precision, and knowledge. Steel fabricators are well aware of all the crucial steps and measures that need to be taken care of in the fabrication process.  Structural steel is usually fabricated to create structures like beams, trusses, hollow sections, angles, and plates. ERECTION : The erection of structural steelwork consists of the assembly of  steel components  into a frame on site. The processes involve lifting and placing components into position, then connecting them together. Generally, this is achieved

 SPIN WHEEL ACTIVITY  Isn't it boring to learn things in the usual way? How about learning it all through some fun activity !!! The spin wheel is very easy to make just by following few steps.  Materials required for making the spin wheel  Pens/ pencils Papers Scissors/ cutter  Glue Compass Ruler Pin/ thread The following are the 3 simple steps I followed in making the spin wheel :  Step 1 The papers shall be cut into 3 circles with required measurements. Step 2 Write necessary information in all the circles according to the spin.  Step 3 Arrange the circles in order and tie it using thread or just pin it.  The spin wheel is ready to be played with.  - Nandhini P

  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     IMAGE REFERENCES:                                                 https://blog.swantonweld.com/structural

FABRICATION, ERECTION & HYBRID STRUCTURES  Hello guys! We are going to take a look at the fabrication and erection processes of steel construction and hybrid structures.  Fabrication process: Fabrication is the process used to manufacture steelwork components that will when assembled and joined forms a complete frame.  Structural steel fabrication can be carried out in a shop or at the construction site. Fabrication carried out in shops is precise and of assured quality whereas fabrication in the construction site is comparatively inferior in quality.  Sequence of activities in fabricating shops: 1. Surface cleaning  2. Cutting and Machining  3. Punching and Drilling  4. Straightening, bending and rolling  5. Fitting and reaming  6. Fastening (Bolting, riveting and welding) 7. Finishing  8. Quality control 9. Surface treatment 10. Transportation Issues in Fabrication process: - External damage to materials - Immediate Spring back after fabricating - Price volatility of raw material

  Steel fabrication, erection and hybrid construction Fabrication: In fabrication methods such as grinding, welding, cutting, bending, drilling, punching, burning or melting are involved. High quality tools and Computer Numerical Controller equipment is also used. Crucial steps and measures are needed to be done in this process. Structural steel is usually fabricated to create structures like beams, trusses, hollow sections, angles and plates. Structures have to be specifically designed and fabricated before constructing and assembling them together.   Steel erection:   Erection is done with the help of cranes or by jacking and lifting and placing components. Bolted connections are done to keep the components secure and bracing is also done. Structure alignment is essential by checking the column bases to be lined and levelled. The process involves lifting and placing an exact position by connecting together. Connections may be achieved by bolting, welding, and

Curves: There are about 3 ways to tackle curves. There are quite a few ways and methods to barge our way through these, quite technical aspects of design. Induction bending is an application of specific heat, and used for industrial pipes. Ways to create curves are: Bend the Steel. Use a 3 point smooth bending machine. Use a break press and heat applied bending. Now, facet the building to give the appearance of curves, and use straight members. Cut curved forms out of the plate material. Various bending steel issues are, Member type, orientation of member, length of member, shipping considerations, sourced out work, accuracy of curve, multiple curves. Castings: Contemporary castings are used for special connections and standard connections. Can be one of large pieces formed with expandable molds. They can be smaller die cast pieces made in great quantity. They are either solid or hollow. Its uses are: Architecturally exposed structural steel particularly for HSS or timber c

  Glass and Steel Construction: Glass with a density comparable to reinforced concrete presents modulus of elasticity almost equal to that of aluminium. Glass is several times weaker in tension than in compression. The fracture pattern of glass is highly dependent on residual stress. Annealed float glass breaks into large fragments whereas fully tempered glass presents high fragmentation and breaks into small pieces which does not affect post-breakage strength. Metal enforced glass beams: Comparing the load-bearing capacity of different glass beams in four configurations of glass strips: layered laminated, laminated segmented and laminated reinforced glass, Veer   has proved that even small amount of steel bonded to tensile side of a glass beam improves the post-breakage performance of the beam significantly. Carbon and glass fibre reinforced glass beams: A carbon fibre strip was bonded to the bottom edge of a glass beam with a structural adhesive. The main role of the solutio
