Introduction to Products
I. Production Process

Huachengxing Air Duct Fireproof Board is produced from high-grade fire-resistant quartz powder, flame-retardant minerals (mica, perlite), cement, and multiple functional additives. Reinforced with premium refractory composite fibers and other mineral fibers, the product is formed through advanced manufacturing technology, followed by specialized treatments including high pressure, high temperature, and steam curing. This sophisticated production system guarantees stable and outstanding performance.


II. Product Features
Lightweight & High Strength
Huachengxing Air Duct Fireproof Board has a unique structural design that makes it considerably lighter than conventional concrete or clay bricks, while delivering exceptional flexural strength. It is lighter yet stronger than standard plasterboards of the same thickness.
When applied in exhaust systems under external pressure or smoke extraction systems, it exhibits excellent performance: high strength, light weight, good ductility, and strong seismic resistance.
Excellent Fire Resistance
Huachengxing Air Duct Fireproof Board complies with Class A non-combustible standards. After installation, it maintains outstanding stability and structural integrity, providing reliable fire protection.
In case of fire, it effectively confines flames to the initial pipeline section and ensures reliable fire isolation. Composed of inorganic flame-retardant fiber materials, the board does not burn or release toxic gases at high temperatures, fully complying with the fire safety principle of “prevention first, prevention over rescue”.
Easy to Process & Install
Huachengxing Air Duct Fireproof Board can be easily planed, sawn, nailed, and drilled, supporting highly flexible and efficient design and construction solutions.
Good Load-Bearing Performance
With high structural strength, the air duct board can reliably withstand certain wind loads during operation.
High Durability
Made of inorganic silicate-calcium materials, the air duct board is anti-aging, weather-resistant, mould-proof, and corrosion-resistant. It remains stable and deformation-resistant even in humid environments. As a high-performance building material, its service life is consistent with that of major building structures.
Eco-Friendly & Non-Toxic
The production process of Huachengxing Air Duct Fireproof Board is pollution-free and does not produce hazardous waste. It is a new-generation green building material with no radioactivity or harmful substances, ensuring safety under different temperature and humidity environments.
Cost-Effective & Practical
Thanks to its thin thickness and lightweight characteristics, Huachengxing Air Duct Fireproof Board improves construction flexibility, reduces structural load, and effectively shortens on-site installation time.


III. Scope of Application
Huachengxing Air Duct Fireproof Board is widely used in self-supporting air ducts, workbenches, interior and exterior building walls, fireproof cladding for steel columns and beams, raised floor linings, tunnel interior linings, residential renovations, as well as ceilings and partition walls in industrial and commercial projects.
Construction companies, designers, and contractors may select this product according to their project-specific requirements.
As a professional fireproof building material, Huachengxing Air Duct Fireproof Board has been widely applied in major first‑ and second‑tier cities including Beijing, Shijiazhuang, Hohhot, Baotou, Tianjin, Shanghai, Guangzhou, Xi’an, and Dalian.

IV. Installation Method
Self‑Supporting Fireproof Board Air Duct
The structure of the self‑supporting fireproof board air duct is shown in Figure 1, with a detailed enlarged view of the corner joint in Figure 2.
Fireproof Cladding for Metal Air Ducts
The structure of a metal air duct with external fireproof board cladding is illustrated in Figure 3, with a detailed joint view in Figure 4.
A U‑shaped light‑gauge steel channel is fixed to the exterior of the metal duct, and the fireproof board is then installed onto this steel framework.
Plate Cutting and Forming
The four wall panels of a rectangular fireproof air duct shall be cut according to construction drawings, duct dimensions, and panel thickness, including panels for duct bends and transition sections.
Plate Specifications
Standard size: 2440 mm × 1220 mm
Thickness: 9 mm, 12 mm, 15 mm
Generally, each duct section is manufactured at a length of 1220 mm based on the standard panel width.When the duct length ≤ 1220 mm, or the sum of its two side lengths ≤ 1220 mm, the duct can be fabricated along the 2440 mm length of the panel to minimize joints.

Panel splicing should be avoided whenever possible. If splicing is necessary, it must comply with the requirements shown in Figure 5, and reinforcement measures shall be applied at the spliced sections.
