Langhui ALC/AAC Fireproof Wall Panel (for steel column/beam cladding)
FirewallsLanghui ALC/AAC autoclaved aerated concrete panels for fireproof walls and cladding, used to protect steel columns and beams. Thin panels installed on a light steel frame and fixed with self-tapping screws, creating a lightweight fire barrier with thermal and acoustic insulation for steel structures.
Fire-rated Wall
Langhui is located in the key Gaoming Industrial Development Zone of Foshan. Its modern production facility covers approximately 246 mu (about 16.4 hectares) with a total investment of around 420 million RMB, situated in the heart of the Greater Bay Area and fully leveraging the region's synergies in manufacturing, logistics, and technology. Backed by one of China's leading production lines for ultra-thin ALC/AAC panels, Langhui panels have been exported in large quantities to light steel frame projects in Australia, Japan, and South Korea, establishing a solid reputation in the international market.

Why Choose This Product Line?
Specialized in ALC/AAC
Company-owned facility in Foshan Gaoming with leading ultra-thin panel production line, covering the full range of wall, floor, roof and fire-resistant panels.
Light yet Strong
Fine air bubbles provide low self-weight with considerable strength, reducing structural load and making panels easy to handle and quick to install.
Fire Safety
Inorganic non-combustible material, does not ignite or emit toxic fumes when exposed to fire — a reliable choice for fireproofing steel columns and beams, and for fire-resistant partitions.
Thermal and acoustic insulation
Closed-cell foam structure provides excellent thermal and acoustic insulation, making walls more energy-efficient and interior spaces quieter.
Export quality
Bulk exported to steel frame projects in Australia, Japan, and South Korea, long-verified in international markets.

🔧Installation Guide
- 1.Select panel type based on application: interior and exterior partitions, external walls, floors, roofs, and fireproof encasement of steel columns and beams; choose thickness based on load and fire resistance rating.
- 2.Wall panels are fixed to beams and floor slabs using panel clips, with L=25mm powder-actuated fasteners and M8 metal expansion bolts; fire-resistant wall panels are installed on light-gauge steel framing and locked with self-drilling screws.
- 3.Floor and roof panels are placed on steel beams and connected using steel angle brackets and M12 chemical anchors, with overlap and anchorage controlled per engineering drawings.
- 4.Tightly fill panel joints with cement mortar and properly treat connection nodes to ensure reliable sound insulation, fire resistance, and crack resistance.
- 5.When joints are dry, skim coat with joint compound and apply interior wall paint, or finish with a thin plaster layer as per project requirements, resulting in a smooth, beautiful wall.
🧽Care & Cleaning
Store panels flat in a dry, sheltered area, raised off the ground; during storage, protect panel edges and corners from impact, rain, and moisture.
Use hand saws, power saws, or specialized hole saws for clean, straight cuts; after creating chases for pipes, promptly fill the chases completely with mortar to avoid voids.
Use a bonding primer and thin-coat mortar suitable for AAC substrate; fill joints according to specifications and embed reinforcing mesh to effectively prevent cracking of the finish.
After installation, protect wall surfaces and panel edges from heavy impact; in wet areas, apply a waterproofing base layer before finishing to extend the wall's lifespan.
