Quality & Manufacturing
A smart-factory production route for renewable-energy and structural components, with cutting, welding, coating and inspection steps selected for the applicable project specification.
Digitally controlled, ground-up for low tolerance.
East Baoyu's 2026 facility is a digitally controlled production environment built for the dimensional, low-tolerance demands of solar & structural components — backed by 30+ years of Baolai steel discipline.

Manufacturing capabilities selected by project route.
The quotation and quality plan identify the material, processing, coating, inspection and documentation responsibilities for each order.
Laser Digital Cutting
Fiber-laser lines cut plate and section to exact geometry, repeatable across high-volume batches.
±0.5mm toleranceCNC Punching & Drilling
Automated hole-positioning for bolted connections — accurate, consistent and fast.
Programmable positioningRobotic Welding
Automated welding cells deliver high-integrity, repeatable structural joints.
EN 1090 · AWS D1.1Hot-Dip Galvanizing
Galvanizing routes for project-specific corrosion protection, with coating class and inspection requirements defined by the applicable specification.
Coating class by project specificationSurface Coating
Painting and powder-coating options for colour, environment and finish.
Paint / Powder coatForming & Bending
Cold-roll forming and press-brake bending for sections and custom profiles.
Cold-formed sectionsReal lines, real output.
Fabrication
Output
GalvanizingDefined checkpoints and documented release.
Material traceability, in-process checks and final release activities are defined by the applicable specification and Inspection and Test Plan.

Material Traceability
Material identity and mill documentation are reviewed and recorded to the level required by the order and inspection plan.

In-Process Inspection
Dimensional, welding and coating checks are assigned to defined production stages and acceptance criteria.

Pre-Shipment Verification
Final inspection, testing and release documents follow the agreed sampling plan, ITP and contract scope.
