What Are the Load-Bearing Requirements for GRC Panels Used in Suspended Ceilings? Qinglong GRC Ceiling System Technical Standards

When GRC panels are used for ceilings, the load-bearing requirements are: self-weight (including the suspension system) ≤0.3kN/m², and single-point suspension force ≥1.5kN. The ceiling system must have a safety factor ≥3, with deformation ≤L/250 under 1.5 times the design load. Keel spacing is determined by panel thickness: spacing ≤400mm for 8mm panels, spacing ≤600mm for 10mm panels.

For a GRC ceiling at a large commercial center, a dedicated light steel keel system was used. Verified by calculation, under an additional load of 0.5kN/m² (accounting for air ducts, light fixtures, etc.), the maximum deflection was 3.2mm (span 1200mm), far below the code limit. The Qinglong GRC ceiling system has passed testing by the National Fastener Quality Supervision and Inspection Center, with all indicators meeting GB 50009 requirements.

Load Calculation Standards

Self-weight ≤0.3kN/m²; live load ≥0.5kN/m²; these standards ensure safety.

Suspension System Requirements

Single-point suspension force ≥1.5kN; safety factor ≥3; these requirements ensure reliability.

Deformation Control Indicators

Serviceability limit state ≤L/250; these indicators ensure flatness.

Installation Key Points

Keel flatness ≤2mm/2m; these key points ensure quality.

Ceiling load-bearing requires precise calculation. Qinglong GRC system solutions are safe and aesthetically pleasing.
