Product Overview
We launch high-quality cement pressure board series products, made from high-grade Portland cement, quartz sand, and asbestos-free reinforced fibers (plant fibers/inorganic fibers) through sheet molding, high-pressure pressing, and natural curing processes. Integrating excellent high-strength load-bearing, weather resistance, corrosion resistance, fire resistance, moisture resistance and stable durability, the products feature a practical and adaptable design. They can not only serve as structural substrates to ensure building stability but also meet the functional needs of various indoor and outdoor scenarios. It is an ideal choice for architects, decoration companies, contractors and owners for partitions, ceilings, exterior wall cladding, floor underlayment and fire partitions, widely applicable to commercial, public, residential, industrial and other construction projects.

Frequently Asked Questions (FAQ)
Q1: What is the service life of the cement pressure board?
A: Under normal use and maintenance conditions, the service life can reach 25–30 years for indoor use and 15–20 years for outdoor use. If the exterior wall anti-corrosion coating is well applied, the service life can be extended to more than 20 years, depending on the use environment and installation quality.
Q2: Can the board be directly used in outdoor open environments?
A: Absolutely. The product has extremely strong weather resistance, freeze-thaw resistant, UV resistant and corrosion resistant, making it the preferred material for outdoor exterior wall cladding, landscape buildings and open-air ceilings; it is recommended to seal the joints and treat the edges during installation to improve waterproofness.
Q3: What is the difference between cement pressure board and calcium silicate board?
A: The core difference lies in strength and density: cement pressure board has higher density (1.5–2.0 g/cm³) and greater strength, better load-bearing and weather resistance, more suitable for outdoor and load-bearing scenarios; calcium silicate board has lower density (1.2–1.8 g/cm³) and better flatness, more suitable for indoor partitions and ceilings. Both are Class A1 fire-resistant and moisture-proof materials.
Q4: The board is relatively heavy, what should be noted during installation?
A: The board has high density, and the weight of a single sheet (such as 12mm thick is about 45 kg/sheet) is greater than ordinary boards. During installation, ensure that the keel spacing meets the specifications (recommended ≤400mm), use special anti-corrosion screws for fixation, and operate with multiple people; do a good job of safety protection for high-altitude installation, and it is recommended to be installed by a professional construction team.
Q5: How to clean and maintain it daily?
A: Daily cleaning can be done by wiping surface dust and stains with clean water or neutral detergent, no special maintenance is required; avoid long-term contact with strong acidic chemicals (such as hydrochloric acid, sulfuric acid) to prevent corrosion of the board surface; it is recommended to check the sealant of outdoor boards every 3–5 years and reapply waterproof coating if necessary.
Q6: Does the product meet the asbestos-free environmental requirements?
A: Yes, our cement pressure boards are all asbestos-free formulations, using plant fibers or inorganic fibers as reinforced materials, fully complying with national asbestos-free environmental standards, and have passed the testing and certification of authoritative institutions, which can be safely used in various construction projects.
Q7: Does it support personalized customization?
A: Yes. We can customize special sizes and thicknesses (such as ultra-thin 3mm, extra-thick 50mm) according to project requirements, and also customize functional surfaces such as waterproof, anti-corrosion and stone-like textures. At the same time, we can provide cutting, chamfering and other processing services. For details, you can communicate with the business team.
