In data centers, office buildings, and modern industrial facilities, raised access floor systems are critical infrastructure supporting key equipment and cable management. The journey of a seemingly simple, fully steel concrete raised access floor panel—from manufacturing and logistics to final installation underfoot—involves numerous precise and rigorous processes. As a professional supplier, Huilian is committed to providing the global market with high-quality products that meet local standards. This article details the story behind every Huilian steel concrete raised floor panel.

Step 1: Raw Material Selection and Inspection

Quality begins with superior raw materials. Huilian selects premium cold-rolled steel plates as the base material, ensuring high strength and corrosion resistance. Steel thickness and zinc coating quality are strictly screened against international standards. Beyond the core steel, auxiliary materials are also chosen with precision: high-strength formula foam cement for cavity filling ensures overall rigidity and stability; surface laminates like high-wear, fire-resistant HPL or PVC are used for the top layer; and high-purity conductive materials form the edge strips, guaranteeing stable, long-lasting anti-static performance. These stringent selection criteria form the foundation for compliance with global market regulations and long-term reliability. Every material batch at Huilian comes with strict quality inspection reports, ensuring excellence is determined from the very source.

Step 2: Precision Manufacturing and Processing

Transforming raw materials into finished panels involves over a dozen precise steps, each embodying Huilian's craftsmanship and technical expertise.

1. Stamping and Forming: The base plate is stamped and stretched by large hydraulic presses to form recessed structures per design specifications, laying the foundation for subsequent filling and load-bearing. This step meticulously controls force and precision, keeping dimensional tolerances within millimeter-level accuracy.

2. Punching: Precisely punched holes are created in the formed base plate, providing channels for grouting and ensuring vital ventilation and heat dissipation—critical for applications like data centers.

3. Cutting and Trimming: Steel plates are accurately cut to standard sizes (e.g., 600x600mm), with excess edges removed to ensure uniformity, interchangeability, and sealing during installation.

4. Riveting and Spot Welding: Automated riveting and multi-point spot welding technologies securely join the top and base plates into a sealed steel shell. An intelligent temperature control system ensures uniform, robust welds, eliminating weak or missed joints to guarantee load-bearing capacity.

5. Surface Phosphating Treatment: The assembled steel shell undergoes a multi-stage phosphating process, including high-temperature degreasing, rinsing, surface conditioning, and final rinsing. This forms a uniform phosphate anti-corrosion film, significantly enhancing resistance to diverse climatic challenges, from humid Southeast Asian environments to cold, snowy European conditions.

6. Drying and Powder Coating: After thorough drying, the phosphated shell enters the electrostatic powder coating stage. Eco-friendly epoxy powder is evenly applied via electrostatic adsorption and then cured at high temperature to form a dense, protective layer.

7. Cavity Grouting: High-strength foam cement is pressure-injected into the steel shell through the pre-punched holes. Automated equipment ensures precise, uniform, and compact filling without voids. After curing at ambient temperature, the cement bonds perfectly with the shell, providing exceptional load-bearing strength while reducing overall weight and floor loading.

8. Laminate Bonding: Automated glue application and roller pressing technology securely bond HPL or PVC laminates to the panel surface. Precise pressure and temperature control ensures tight adhesion without bubbles or edge lifting, preserving the laminate's wear resistance.

9. Edge Sealing: Conductive edge strips are inlaid or PVC edges are molded onto the panel perimeter, enhancing anti-static performance and edge protection against damage during transport and installation.

Step 3: Quality Inspection and Certification

Huilian implements a multi-layered quality assurance system:

• In-Process Inspection: Dedicated inspectors at each key production stage use precision instruments to check dimensional accuracy, weld quality, coating thickness, and more.

• Finished Product Inspection: Completed panels undergo thorough checks for appearance, dimensional precision, flatness, and weight. Surface quality is verified for scratches, dents, color consistency, and smooth edge sealing. In-house testing equipment evaluates concentrated and rolling load performance.

• Third-Party Certification: Huilian regularly engages authoritative third-party labs to test panels for concentrated load, rolling load, fire rating (e.g., UL, CE), and anti-static performance (e.g., ANSI/ESD S20.20), ensuring independent validation for global markets.

Step 4: Custom Packaging and Warehousing

Based on client needs and shipping distance, panels are packaged using a standard palletized system with moisture-proof film, edge protectors, and reinforced pallets to prevent damage during long-haul sea or land transit. Warehouses implement zoned management and FIFO (First-In, First-Out) principles, with clear labeling for all specifications. Huilian also offers customized packaging and branding upon request.

Step 5: International Logistics and Customs Clearance

Huilian operates a mature international logistics network, efficiently arranging container shipping tailored to port requirements in the US, Europe, or Southeast Asia. Each shipment is accompanied by complete documentation support, including certificates of origin, quality certificates, and packing lists, ensuring smooth customs clearance.

Upon arrival at the destination port, trusted local logistics partners ensure safe transport to the project site. Huilian provides professional unloading guidance to maintain product integrity through the final delivery stage.

Step 6: Professional Installation and After-Sales Support

Huilian supplies detailed installation guides and videos covering standardized procedures, key considerations, and schematic diagrams to ensure correct installation and optimal system performance.

Furthermore, Huilian has established a global after-sales service network. Through coordinated online support and local service teams, we ensure rapid response to client inquiries and post-installation needs, guaranteeing project success and long-term satisfaction.
