STRUCTURAL STEEL AND TANKS FABRICATORS - 15 NOS
Job Details
Job Description
**Structural steel fabrication** is the process of cutting, bending, shaping, and assembling steel to create structures and components used in construction projects like buildings, bridges, industrial facilities, and other infrastructure.
Here’s a **basic breakdown** of the structural steel fabrication process:
---
### ???? **1. Design and Engineering**
* Structural engineers create detailed blueprints and specifications.
* 3D modeling software like **Tekla**, **AutoCAD**, or **Revit** is often used.
* The design accounts for load-bearing requirements, materials, dimensions, and local building codes.
---
### ⚙️ **2. Material Preparation**
* **Raw steel sections** (e.g., beams, channels, angles, plates, tubes) are selected.
* Materials are checked for defects and compliance with standards (e.g., ASTM, EN, or ISO).
---
### ???? **3. Cutting**
* Steel is cut to required dimensions using:
* Plasma cutting
* Laser cutting
* Oxy-fuel cutting
* Shearing or sawing
---
### ???? **4. Bending/Forming**
* Steel is bent or shaped using:
* Press brakes
* Rolling machines
* Specialized forming machines
* This helps form components like curved beams or brackets.
---
### ???? **5. Assembling/Fitting**
* Components are tacked together before welding or fastening.
* This includes:
* Beams
* Columns
* Braces
* Trusses
* Bolt holes may be pre-drilled or punched.
---
### ???? **6. Welding**
* Welding joins the steel parts using MIG, TIG, or Stick welding.
* All welds must meet structural codes and may be **non-destructively tested** (NDT).
---
### ???? **7. Surface Treatment & Finishing**
* Cleaning (e.g., sandblasting or grinding)
* Coating for corrosion protection (e.g.,:
* Primer paint
* Galvanizing
* Fireproofing spray)
---
### ???? **8. Inspection & Quality Control**
* Checks for dimensional accuracy, weld quality, material integrity.
* Compliance with standards like **AWS**, **AISC**, or **BS EN 1090**.
---
### ???? **9. Delivery & Erection**
* Fabricated components are shipped to the job site.
* On-site erection involves cranes, bolting, and final welding/adjustments.
---
## Common Structural Steel Components
* **I-beams**
* **HSS (Hollow Structural Sections)**
* **Channels (C-sections)**
* **Angles (L-sections)**
* **Plates and flat bars**
---
## Industries That Use Structural Steel Fabrication
* Commercial and residential construction
* Industrial plants
* Oil & gas
* Shipbuilding
* Infrastructure (e.g., bridges, tunnels)
