Fiber-reinforced cement board What are its characteristics? Let’s all analyze them together below.

　　1. Fire-resistant and Insulating: It is Class A non-combustible—when exposed to fire, the board will neither burn nor produce toxic fumes. It has low electrical conductivity, making it an ideal insulating material. 2. Waterproof and Moisture-Resistant: Even in semi-outdoor, high-humidity environments, it maintains stable performance without sinking or deforming. 3. Thermal Insulation and Soundproofing: With a low thermal conductivity coefficient, it offers excellent thermal insulation. Its high product density ensures superior soundproofing performance. 4. Lightweight yet Highly Strong: The boards, pressed by a 7,000-ton flat hydraulic press, not only boast high strength but are also resistant to deformation and warping. They are lightweight, making them ideal for applications such as roof and ceiling installations. 5. Simple Construction: It’s a dry-process system; installing the framing and boards is straightforward, fast, and efficient. Deep-processed products further enhance ease of installation while delivering even better performance. 6. Economical and Aesthetic: Its light weight makes it perfectly compatible with framing systems, effectively reducing construction and decoration costs. With a uniform appearance and smooth surface, it allows buildings to achieve an even color distribution directly upon application. 7. Safe and Harmless: Its radiation levels are below the national “Hygiene Protection Standards for Radiation from Building Materials,” and measured values are equivalent to those found on grassy areas located 20 meters away from surrounding buildings. 8. Extra-Long Service Life: It is acid- and alkali-resistant, corrosion-proof, and immune to damage from moisture or insects. Its strength and hardness increase over time, ensuring an exceptionally long service life. 9. Excellent Workability and Secondary Finishing Performance: Depending on actual needs, it can be easily sawed, drilled, carved, nailed, trimmed, tiled, or wall-covered—offering versatile processing options.

　　 Fiber-reinforced cement board What are the categories? Let’s all analyze them together below.

　　1. By fiber type: In most regions of China, asbestos fibers are used for reinforcement, and cement boards reinforced with these fibers are referred to as chrysotile asbestos fiber cement boards. The other type is asbestos-free fiber cement boards, in which pulp, wood chips, and glass fibers are used as substitutes for asbestos fibers to provide reinforcement; these boards are collectively known as asbestos-free fiber cement boards.

　　2. Classified by density: low density ranges from 0.9 to 1.2 g/cm³, medium density from 1.2 to 1.5 g/cm³, and high density from 1.5 to 2.0 g/cm³. Low-density boards are typically used for applications such as low-end architectural ceiling and partition walls, while medium-density boards are commonly employed in mid-range architectural partitions and ceilings. High-density boards are generally used for high-end buildings, including steel-structure exterior walls and steel-structure floor slabs. According to national building industry standards, fiber-cement boards in China are divided into two main categories. High-density fiber-cement boards tend to be more prone to deformation; medium- and low-density products, on the other hand, have lower deformation coefficients.

　　3. By pressure type: Whether or not there is a press plate—medium- and low-density fiber cement boards are all without press plates, while high-density fiber cement boards do have press plates.

　　4. By thickness: Ultra-thin boards, 2.5–3.5 mm; standard boards, 4–12 mm; thick boards, 13–30 mm; and extra-thick boards, 31–100 mm. Typically, manufacturers are unable to produce ultra-thin or extra-thick boards—this fact serves as an important benchmark for assessing the production capacity and technological level of companies within the industry.
