PEB Steel Fabrication Quality Control: AWS D1.1 & SA 2.5 Standards (2026)
The structural integrity of a pre-engineered building is determined in the factory. Learn how Fusion Developers enforces AWS D1.1 structural welding codes, ultrasonic non-destructive testing (NDT), and SA 2.5 shot-blasting surface preparation.
1. Submerged Arc Automated Welding (SAW)
All built-up primary portal frames undergo automated twin-arc Submerged Arc Welding (SAW), ensuring complete penetration fillet welds with zero porosity, uniform bead profiles, and minimal heat-affected zones.
2. SA 2.5 Shot Blasting & Epoxy Coating Systems
Mill scale and surface oxidation are stripped via centrifugal automatic shot-blasting to Swedish Standard SA 2.5 near-white metal finish, followed immediately by zinc-rich epoxy primers achieving 80+ microns dry film thickness (DFT).
Frequently Asked Questions
Are mill test certificates (MTC) provided for structural steel plates?
Yes. Every steel heat batch is supplied with certified Mill Test Certificates verifying tensile yield strength (min 345 MPa for A572 Gr 50) and chemical composition.
