Rigorous Quality Assurance & Compliance Framework

Strict Material & Weld Testing Protocols

At Ningbo Kelida, structural integrity is non-negotiable. Led by a team of 22 quality control specialists, we subject every production batch to rigorous safety tests to verify compliance with global engineering standards:

  • Raw Material Tensile Strength Tests: We verify the yield strengths of steel batches (such as Q235B and Q355B) before fabrication.
  • Ultrasonic Weld Inspections: We ensure perfect, defect-free load-bearing joints on all uprights and support beams.
  • Static & Dynamic Load Verifications: Real-world stress testing confirms structural behavior under maximum weight capacities.
  • Salt-Spray Anti-Corrosion Testing: We run continuous corrosion tests to guarantee coating life in high-humidity or cold-storage facilities.

Global Standard Compliance

We manufacture our structures to meet and exceed global cold-formed steel structural racking standards, ensuring straightforward local approvals and safe operation:

  • RMI (Rack Manufacturers Institute) standards for structural safety in North America.
  • FEM 10.2.02 European code compliance for safe industrial steel storage design.
  • AS 4084-2012 compliance for steel storage racking safety and structural performance in Australia.
  • Full CE Certification for European structural execution classes (EN 1090-2).
"Partnering with a supplier that understands international building codes was critical for our 3PL expansion. Kelida delivered customized mezzanine platforms that passed stringent local structural audits in Western Europe without a single revision."

Technology Roadmap & Future Outlook

IoT Structural Health Monitoring

We are piloting IoT stress sensors within mezzanine structural members. These sensors transmit real-time deflection data to facility operators, warning of overload conditions and preventing localized failure risk.

AMR & AGV System Adaptations

Modern platforms require ultra-flat decking and rigid frames to support autonomous logistics robots. Our R&D team is refining specialized high-performance joints to handle dynamic robotic wheel loads.

Sustainable Fabrication & Green Coatings

We target low-carbon manufacturing by using recycled steel feedstocks and energy-efficient powder curing processes, helping international clients meet their corporate ESG targets.

Frequently Asked Questions (FAQ)

What is the difference between a structural steel mezzanine and a rack-supported mezzanine?
A structural steel mezzanine uses heavy-duty structural steel columns and beams to create wide, open ground floors beneath the platform. A rack-supported mezzanine floor relies on storage racks (such as pallet or carton flow racking) as the structural foundation, making it highly cost-effective for picking-intensive operations.
What load capacities can Kelida design and manufacture?
We offer fully customizable configurations supporting loading capacities ranging from light-duty applications (300 kg/m²) to heavy-duty industrial storage platforms (up to 1,500 kg/m²). Our structural engineers run FEA simulations on every layout to ensure design safety.
How does Ningbo Kelida ensure international shipping and installation quality?
All elements are meticulously bundled and crated using heavy-duty packing materials to protect against sea freight moisture and handling damage. Every shipment includes step-by-step 3D installation manuals, CAD layout drawings, and remote engineering consultation support.
Which steel grades are used in your manufacturing facility?
We primarily use premium high-strength cold-rolled carbon steel, such as Q235B and Q355B (equivalent to ASTM A36 and ASTM A572 Grade 50), to optimize the strength-to-weight ratio of all vertical load-bearing columns and beams.
