Langhui ALC/AAC Fire-Rated Wall Panels (steel column & beam encasement)
Firewalls
FirewallsFire-rated wall and encasement solution using Langhui ALC/AAC autoclaved aerated concrete panels, used to protect and encase steel columns and beams. The thin panels are mounted on a lightweight steel framing system and fixed with self-drilling screws, forming a lightweight fire barrier that provides thermal and acoustic insulation for steel structures.
Fire-Rated Walls ยท firewalls
Langhui is located in the Gaoming key industrial development zone of Foshan. Its modern production base covers roughly 246 mu (about 16.4 hectares) with a total investment of approximately RMB 420 million, sitting at the heart of the Greater Bay Area and making full use of the region's synergies in production, logistics and technology. Backed by one of China's leading ultra-thin ALC/AAC panel production lines, Langhui panels are already exported in volume to light steel-frame projects in Australia, Japan and South Korea, earning a solid reputation in international markets.

๐ Applications
Why Choose This Series?
Focused on ALC/AAC
Company-owned base in Foshan Gaoming with a leading ultra-thin panel line, covering the full range of wall, floor, roof and fire-rated wall panels.
Light yet strong
Fine air pockets give low self-weight with considerable strength, reducing structural loads and making the panels easy to handle and quick to assemble.
Fire safety
An inorganic non-combustible material that does not burn or release toxic smoke when exposed to fire โ a reliable choice for fire encasement of steel columns and beams and for fire-rated partitions.
Thermal and sound insulation
The closed-cell air-pocket structure delivers excellent thermal insulation and sound insulation, making walls more energy efficient and interiors quieter.
Export quality
Exported in volume to steel-frame projects in Australia, Japan and South Korea, proven over the long term in international markets.

๐ญManufacturing Process
- โธGuangdong Langhui Building Material Technology (Langhui) operates its own production base in Foshan Gaoming, covering roughly 246 mu (about 16.4 hectares) with an investment of approximately RMB 420 million
- โธCentered on one of China's leading ultra-thin ALC/AAC production lines, with full in-house control of batching, casting, cutting and autoclave curing
- โธSand, lime, cement and a foaming agent are cast in scientifically calibrated proportions, then cured and formed in high-temperature, high-pressure autoclaves for fine, uniform air pockets and stable dimensions
- โธLeveraging the Greater Bay Area's advantages in production, logistics and technology to deliver stable, high-volume supply of ultra-thin wall panels, floor panels, roof panels and fire-rated wall panels
- โธSupports custom panel profiles and thicknesses by application; Langhui ALC panels are already exported in large volumes to Australia, Japan, South Korea and other overseas markets
๐Quality Certifications
- โAutoclaved aerated concrete panels, compliant with ALC/AAC product technical standards and lightweight wall material requirements
- โInorganic non-combustible material with fire resistance and fire-endurance performance, suitable for fire encasement of steel structures and fire-rated partitions
- โFloor and roof panels verified by structural calculation to provide the corresponding load-bearing and crack-resistance performance, compatible with steel-frame and concrete construction
- โEnergy-saving, eco-friendly building material that insulates against heat and sound โ green and low-carbon, aligned with modern building energy-efficiency requirements
- โProducts exported in volume to Australia, Japan and South Korea, meeting the supply and quality requirements of those international markets
๐งInstallation Guide
- 1.Select the panel type by application: interior and exterior partitions, exterior walls, floors, roofs, and fire encasement of steel columns and beams, choosing thickness based on load and fire rating
- 2.Wall panels are secured to beams and floor slabs with a clip (panel clip) connection, using L=25mm shot pins and M8 metal anchors; fire-rated wall panels are mounted on a light steel framing and locked with self-drilling screws
- 3.Floor and roof panels are laid over steel beams and connected with steel angle cleats and M12 chemical anchors, controlling overlap and anchorage per the technical drawings
- 4.Pack panel joints tightly with cement mortar and detail the connection nodes properly to ensure continuous, reliable sound insulation, fire resistance and crack resistance
- 5.Once the joints are dry, skim with filler and apply interior wall paint, or complete a thin-coat plaster finish as the project requires, delivering a flat, attractive wall
๐งฝCare & Cleaning
Stack panels flat in a dry, covered area, raised off the ground; during storage, protect edges and corners from impact, rain and moisture seepage.
Use a dedicated hand saw, power saw or hole saw for clean, straight cuts; after grooving for conduit, promptly fill and pack the channels with mortar to avoid hollow spots.
Use a bonding primer and thin-coat plaster suited to AAC substrates; fill joints per specification and embed mesh tape to effectively prevent the finish layer from cracking.
After installation, protect wall surfaces and panel edges from heavy impact; in wet areas, apply a waterproof base coat before finishing to extend the wall's service life.
