Precision Manufacturing & Compliance
Four uncompromising technical pillars that ensure structural integrity, precise site fit-up, and long-term durability in extreme climate conditions.
Every project is modeled using Tekla Structures 3D BIM software. We extract NC files directly to CNC machines, ensuring 100% clash detection and piece-mark matching for zero-error on-site assembly.
Equipped with heavy H-beam automated Submerged Arc Welding (SAW) lines and high-definition plasma/laser CNC cutting, achieving millimeter-level cutting tolerances and deep weld penetration.
Components pass through an automated 8-impeller shot blasting machine achieving Sa 2.5 cleanliness. We offer ISO 12944 compliant Epoxy Zinc-Rich systems and EN ISO 1461 Hot-Dip Galvanizing (HDG).
All raw steel (Q355B/D, S355JR, A572 Gr50) is sourced with Mill Test Certificates (MTC EN 10204 3.1). Full-penetration welds undergo Ultrasonic Testing (UT) by Level-II certified inspectors.
In-depth technical guides answering complex questions regarding steel standards, anti-corrosion selection, and container shipping.
