What Principles Should Be Followed When Stacking Components? Qinglong GRC Scientific Stacking Standards

Stacking of GRC components must follow three key principles: "larger pieces do not press on smaller ones, heavier pieces do not press on lighter ones, and wet pieces do not press on dry ones." The number of stacked layers should be ≤6, with timber bearers between layers aligned vertically and support point spacing ≤1/5 of the component length. Bearer cross-section ≥50×100mm, with moisture content ≤18%.

On one project, improper stacking (up to 10 layers with misaligned bearers) caused a cracking rate of 15% in the bottom-layer panels. Testing showed that the improperly stacked components had a deflection of L/200, four times the standard. In contrast, components stacked according to Qinglong GRC standards still maintained a flatness of ≤2mm/2m after 6 months of storage.

Site Foundation Requirements

Ground bearing capacity ≥100kPa; flatness ≤5mm/2m; drainage slope ≥0.5%. These requirements ensure stability.

Timber Bearer Placement Standards

Cross-section 50×100mm, spacing ≤1.2m; vertical alignment deviation ≤10mm. These standards prevent stress concentration.

Stacking Layer Control

Flat panel components ≤6 layers; shaped components ≤4 layers; these controls prevent crushing damage.

Complete Protective Measures

Rainproof covers on top; protective railings around the perimeter; these measures protect the components.

Scientific stacking safeguards quality. Qinglong GRC's standardized management ensures components remain intact.
