Fabrication disciplines

Engineered steel fabrication disciplines

From mathematical load verification in 3D TEKLA environments to heavy shop assembly and crane rigging, Sayel provides complete industrial structural frameworks engineered for zero margin of deflection.

Scope of execution

Full structural lifecycle

Phase 01 - Engineering

TEKLA 3D structural detailing

Our Erbil detailing studio translates architectural contract designs into fully parametric shop models, generating automated CNC drill files, center-of-gravity calculations, and clash-tested member connection drawings.

Phase 02 - Processing

Heavy CNC plate profiling

Multi-axis high-definition CNC plasma and submerged arc welding bays cut, bevel, and seam plates up to 80mm thickness, guaranteeing clean root penetration and tight assembly tolerances across complex nodes.

Phase 03 - Preservation

SA 2.5 blast and coating

Steel surfaces undergo automated centrifugal grit blasting to Swedish standard SA 2.5 before receiving specified zinc-rich primer and aliphatic polyurethane intermediate coats inside climate-controlled containment bays.

Phase 04 - Assembly

Heavy field crane erection

Certified rigging crews manage synchronized mobile crane tandems, positioning multi-ton truss chords onto prepared column heads with dedicated site surveying and immediate bolt tension verification.

Material mill verification

Non-destructive weld testing

3D laser dimension scan

Climate-controlled coating QA

Every incoming heat of structural plates and rolled I-sections is cross-checked against certified mill test reports for yield tensile limits and chemical composition.

Critical moment welds, full-penetration joints, and truss splices undergo 100% ultrasonic and magnetic particle testing administered by certified Level II inspectors.

Fabricated nodes, camber curvature, and bolt-hole clusters are mapped using total station laser trackers to ensure strict adherence within 1mm layout tolerance.

Dry film thickness, ambient relative humidity, and surface profile depth are measured with digital gauges before dispatch release documentation is signed.
