Steel fabrication encompasses a series of intricate processes aimed at transforming raw steel into various structures, ranging from frames to platforms and ladders. These processes involve meticulous attention to detail and skilled craftsmanship to ensure the final product meets stringent quality standards. Let’s delve into the systematic steps involved in steel fabrication:
Surface Cleaning:
The initial step in steel fabrication is meticulously cleaning the surface of the steel to remove any mill scale and rust. Various methods, such as hand preparation using wire brushes and emery paper, are employed to achieve a clean and smooth surface, essential for subsequent fabrication processes.
Marking:
Marking is the process of laying off the measurements from the design and into the workpiece. This is sometimes included in the preparation process. Edges, fold lines, and hole centers are scribed on the surface of the workpiece. These scribes or marks must remain visible during the actual fabrication. Common marking tools are metal scribers, pencils, chalks, dividers, and punches. Aside from the measuring devices, marking is aided by tools such as rulers, center squares, and Tsquares.
Cutting and Machining:
Following surface cleaning, the steel undergoes cutting and machining processes to shape it according to the desired specifications. This includes shaping, drilling, turning, and grinding. Different cutting methods like shearing, flame cutting and cold sawing are employed based on the thickness and type of steel.
Punching and Drilling:
Punching and drilling involve creating holes in the steel components using specialised equipment. These holes are crucial for joining components together and accommodating fasteners such as bolts and screws.
Bending, and Rolling:
After cutting and drilling, the steel may undergo straightening, bending, and rolling processes to achieve the desired shapes and dimensions. Roller bending and folding are commonly used methods to bend and shape the steel according to specific design requirements.
Fitting:
Fitting involves aligning and temporarily joining steel components through tack welding to ensure proper assembly before final welding. This step is crucial for achieving precise alignment and structural integrity.
Methods for the Fastening process:
Essentially, there are three different types we can join the parts of the structure.
- Bolting: In this process, bolts and nuts create joints between structural elements and fasten them.
- Riveting: This method uses permanent mechanical fasteners, also known as rivets. Which helps fasten structural elements together.
- Welding: This method uses heat and pressure to fasten. The fastened parts form a joint after cooling.
Welding:
Precision welding plays a vital role in steel fabrication, as it joins individual steel pieces together to form cohesive structures. Skilled welders employ heat to fuse the metal pieces, creating strong and durable joints that withstand rigorous use.
Final Step:
Surface Treatment:
The final step of the manufacturing process of steel fabrication is Surface treatment. In this step, blasting, painting, or galvanizing treats the surface of the finished product to achieve certain benefits.
Primary methods for Surface Treatment:
- Blasting and painting: The professionals use the blasting technique on the finished product to smoothen the rough surfaces, remove surface contaminants or shape a surface. A two-layered process of painting follows the blasting.
- Preliminary step is the application of Red oxide or Zinc oxide. It forms a prime coat on the steel surface.
- Final step is forming an outer layer for beauty and protection. The application of oil, epoxy or other types of paint forms this outer layer.
Main Steps of Structural Steel Fabrication Process
Design Preparation
Drawings and specifications for the project are created and agreed. Draftsman can start creating exact Bill of Material (BOM) and Bill of operations (BOO).
Material Acquisition
Purchases will take it over to acquire the required materials for the project. Involves ordering the steel.
Steel Cutting and Drilling
Time to bend and weld the steel. Various bending processes are performed to create the desired shape.
Bending and welding
Time to bend and weld the steel. Various bending processes are performed to create the desired shape.
Quality Check
Visual inspections, dimensional inspections, and mechanical tests. Non-destructive testing (NBT) is also performed.
Finishing
Steel is then sandblasted and painted. The finishing process is performed before installation.
Delivery, Assembly, and Installation
The assembly process usually involves bolting, riveting, or welding the steel parts together.
