Why Overseas Buyers Partner with PrimeBay
From prime steel coil sourcing to automated precision forming and rigorous load testing, we enforce complete control over every stage of production.
High-Efficiency Automated Production Capacity
Our workshop features continuous automated roll-forming equipment capable of handling high-grade Q235B and Q355B structural steel coils. Automatic punching units ensure accurate hole pitches across upright profiles, ensuring effortless beam connector engagement and seismic safety.
By automating raw material feed, profile shaping, and beam welding, PrimeBay maintains exceptional manufacturing consistency and high output volume, fulfilling large-scale project contracts on strict delivery schedules.
- High-speed automated upright and beam roll forming lines
- Robotic welding for beam connectors and base plates
- Custom beam lengths, upright profiles, and duty ratings
Strict ISO 9001 Quality Control System
Quality is the cornerstone of PrimeBay. Every mill certificate is audited against incoming steel stock, and finished components undergo thorough structural, coating, and dimensional testing before export container loading.
Our Quality Control (QC) engineers verify load-bearing capacity, deflection ratios under full design weight, paint adhesion, and salt spray resistance to guarantee long service life in harsh warehouse environments.
- Certified to CE, ISO 9001, ISO 14001, and TUV requirements
- Full traceability from raw steel coils to packaged components
- Zero-defect policy with batch test reports available for buyers
