Engineering Fundamentals & Design Principles
Factory Production Control (FPC) at SerBuild operates under the harmonized European standard EN 1090-2. From the qualification of welding procedures (WPQR/WPS per ISO 15614) and certified welders (ISO 9606-1) to non-destructive testing (VT, MT, UT per Level II personnel), our automated plant guarantees that every beam, truss, and cold-formed profile leaves the manufacturing line compliant with Execution Classes EXC2 and EXC3.
All structural fabrications undergo CNC multi-axis laser verification to maintain Class 1 manufacturing tolerances.
Applicable Design Standards & Codes
- Execution Classes EXC2 and EXC3 compliance for industrial, commercial, and residential buildings
- Traceable raw materials with EN 10204 Type 3.1 inspection certificates for every steel batch
- Welding Procedure Specifications (WPS) and WPQR qualifications per ISO 15614 / ISO 9606-1
- Non-destructive testing (NDT) including visual (VT), magnetic particle (MT), and ultrasonic (UT) weld checks
Engineering Deliverables Provided
- Mill Test Certificates (MTC 3.1) for all structural coils and hot-rolled profiles
- Factory Quality Control Inspection & Test Plan (ITP) sign-off sheets
- Dimensional tolerance verification reports matching EN 1090-2 Annex D
- Surface preparation (SA 2.5 shot-blast) and dry film thickness (DFT) paint coating reports
Factory Production Control (FPC) Inspection Matrix
Summary of governing standards, compliance thresholds, and engineering significance:
| Parameter / Check | Governing Standard | Specification / Value | Significance |
|---|---|---|---|
| Execution Classes | EN 1090-2 §4 | EXC2 (Standard Bldgs) & EXC3 (Dynamic/Heavy Hall Bldgs) | Defines mandatory inspection levels, testing frequency, and welding rigor. |
| Welder Certification | ISO 9606-1 / ISO 14732 | 100% Certified Manual & Robotic Operators | Ensures structural weld integrity without internal porosity or inclusions. |
| Welding Quality Level | ISO 5817 Level B / Level C | Level B for EXC3, Level C for EXC2 | Eliminates structural fatigue risk on overhead crane and portal frame joints. |
| Non-Destructive Testing (NDT) | ISO 17637 (VT) / ISO 17638 (MT) / ISO 17640 (UT) | 100% Visual (VT) + Random Ultrasonic/Magnetic | Detects subsurface fissures and weld penetration defects. |
| Surface Preparation | ISO 8501-1 | SA 2.5 Centrifugal Automated Shot-Blasting | Creates optimal surface roughness (Rz 40-75 µm) for epoxy adhesion. |
