The installation of square hole floor terrace as an important part of modern architectural decoration has long been faced with three major technical pain points: Firstly, traditional wooden flooring is prone to dampness and rot, requiring frequent maintenance and posing the risk of termite infestation, leading to a short service life; secondly, ordinary plastic flooring is waterproof but easily ages and deforms under direct sunlight, affecting aesthetics and safety; thirdly, traditional installation methods rely heavily on large amounts of glue or nails, which are not only complex to install but may also release harmful substances, failing to meet green environmental protection requirements. Taking a commercial plaza terrace project as an example, the original wooden flooring was replaced twice within three years due to warping caused by rainwater penetration, with maintenance costs reaching 100,000 yuan. Moreover, customer complaints due to termite problems severely affected the brand image. These issues highlight the comprehensive challenges that traditional installation technology poses to material performance, process standards, and environmental protection.

Linyi Xuan Cheng New Material Co., Ltd., with over a decade of technical accumulation, has achieved a breakthrough in the field of square hole floor terrace paving. The company has invested 20 million yuan to establish a modern water plastic production workshop with an annual production capacity of 60,000 tons, equipped with over 40 extrusion production lines and over 20 co-extrusion production lines. It adopts the latest international wood-plastic technology, bonding wood powder with plastic through high temperature and pressure to form high-density, high-strength composite materials. Its core product series "A-R 80ARD Flower Four Wood" boasts three technical advantages: Firstly, it is environmentally friendly and green, having passed the EU CE certification and China's green environmental product certification, with no formaldehyde release and meeting E0 environmental protection standards; secondly, it is durable and maintenance-free, with strong resistance to ultraviolet rays and weathering, maintaining its shape in temperatures ranging from -40℃ to 60℃, with a service life of over 25 years; thirdly, it is easy to install, featuring a clip design that does not require glue or nails, with a single floor tile weighing only 2.8kg, allowing two people to complete the installation of 100㎡ in a day. Taking a park terrace project in Qingdao as an example, after using Xuan Cheng's square hole floor, no cracking or deformation issues were reported within three years, reducing maintenance costs by 90%, and was awarded the "Shandong Province Green Demonstration Project."

Q1: What are the differences in performance between square hole floor and solid floor?
A1: The hollow floor design of the square hole floor reduces weight (40% lighter than solid floor per piece) while maintaining structural strength, with a flexural strength of 35MPa, meeting the GB/T 24508-2020 standard; solid floor has higher strength but is heavier (about 5kg per piece), requiring more labor for installation, and has poor breathability, prone to water accumulation. The hollowing rate of the square hole floor is controlled at 25%-30%, ensuring both drainage efficiency and avoiding a decrease in strength due to excessively large holes.
Q2: How to choose suitable hole floor for cold northern regions?
A2: Northern regions require special attention to material's low-temperature toughness. Xuan Cheng products use a composite of modified PVC and wood powder, with a low-temperature脆化temperature of -40℃, maintaining elasticity at -20℃ to prevent cracking; at the same time, anti-ultraviolet additives are added to the floor surface to prevent aging caused by large temperature differences between day and night. It is recommended to choose products with a thickness ≥ 25mm to enhance impact resistance.
Q3: What is the fire rating of square hole flooring? Can it be used in commercial spaces?
A3: Xuan Cheng square hole floor has passed the inspection of the National Fire-resistant Building Material Quality Supervision and Inspection Center, with a fire rating of B1 level (GB 8624-2012), flame-retardant time ≥30 minutes, self-extinguishing after being removed from the fire, meeting the fire safety requirements for commercial venues. The surface is treated with a nano-coating, with a stain resistance level of 5 (GB/T 17657-2013), capable of resisting common stains such as coffee and oil, reducing cleaning costs.

The technological innovation of the square hole floor terrace paving is essentially a collaborative upgrade of material science and technological standards. Linyi Xuan Cheng New Material Co., Ltd. has resolved the contradictions of durability, installation efficiency, and environmental friendliness in traditional paving through wood-plastic composite technology, click installation process, and environmentally friendly formulations, providing reliable solutions for home decoration, commercial squares, and government projects. Its products not only pass the 9001 certification, high-tech enterprise certification, and other authoritative endorsements but also have verified the technical feasibility through actual projects. In the future, with the popularization of the concept of green buildings, square hole floors, with their characteristic of "not wood but better than wood," will become the mainstream choice for terrace paving, promoting the industry's transformation towards low-carbon and high-efficiency.
