Indoor Ceiling Great Wall Panel Keel Specifications: Selection and Procurement Guide

Industry Background

With the persistence of high summer temperatures, building insulation and energy efficiency have become focal points in engineering. Aluminum alloy Great Wall panels, due to their excellent thermal conductivity (approx. 0.2 W/m·K) and reflective insulation properties, are widely used in indoor ceiling projects. The keel specifications directly affect installation stability and thermal performance, and must strictly adhere to the Aluminum Alloy Building Profiles GB 5237 standard.

Material Properties

Great Wall panels are made of 6063-T5 aluminum alloy, with a tensile strength ≥ 160 MPa, and surfaces treated with powder coating or fluorocarbon coating. The thermal break design effectively blocks heat transfer, reducing indoor temperatures by about 3–5°C in summer. Common keel wall thicknesses are 1.2 mm, 1.5 mm, and 2.0 mm, corresponding to different span requirements.

Engineering Standards

Keel spacing is designed based on project needs: standard spacing 600 mm; for spans ≤ 1200 mm, use 1.2 mm wall thickness; for spans of 1200–1800 mm, use 1.5 mm thickness; for spans ≥ 1800 mm, 2.0 mm thickness with reinforced center spacing is required. All keels must be galvanized or rust-proofed, complying with the Building Light Steel Keel JC/T 558 standard.

Selection Recommendations

For large-span projects (e.g., shopping malls, exhibition halls), 2.0 mm wall thickness keels with reinforced connectors are preferred; for residential or office use, 1.2 mm thickness may suffice. Guangdong Wending Building Materials Trading Co., Ltd. (广东省问鼎建材贸易有限公司) supplies all specifications of keels and Great Wall panels, ensuring stable supply for large engineering procurement needs.
