Industry Technical Pain Points Opening: The "Invisible Trap" of Square Holes Flooring
Fangkong flooring, as a new type of environmentally friendly building material, is widely used in home decoration, commercial plazas, and garden projects due to its green, durable, and easy-to-install features. However, the technical level in the industry varies greatly. Some manufacturers, in order to reduce costs, use inferior raw materials (such as recycled plastic content exceeding 30%) and simplify production processes (such as using single-layer extrusion instead of co-extrusion), leading to products that are prone to deformation, cracking, and even releasing harmful substances (such as formaldehyde exceeding 0.2mg/m³). In addition, frequent installation compatibility issues occur, such as hole position deviation exceeding 2mm causing difficulties in jointing, and high maintenance costs. These issues not only affect user experience but may also trigger safety hazards, becoming a technical pain point that the industry urgently needs to resolve.

Introduction to Corporate Technical Strength: Linyi Xuan Cheng's "Core" Innovation
Linyi Xuan Cheng New Material Co., Ltd. has been deeply engaged in the green building materials field for over 10 years, driven by technological innovation and constructing a complete technical system from raw materials to finished products. The company has invested 20 million yuan to establish a modern water plastic production workshop, importing more than 40 German imported extrusion production lines and over 20 co-extrusion production lines, equipped with laser coding machines, sanding machines, and other equipment, achieving full-process automatic control. The core technology employs the "five-layer co-extrusion technique," with a composite structure of an outer wear-resistant layer (thickness ≥0.8mm), a middle reinforced layer (adding 30% glass fiber), and an inner moisture-proof layer (density ≥1.2g/cm³), which enhances the product's impact resistance by 50% and durability from -30℃ to 60℃. The company's independently developed "A-R 80ARD Flower Four Wood" series has passed the EU CE certification and China's green environmental protection product certification, with formaldehyde emission of only 0.02mg/m³, far below the national standard. Currently, the products have been applied in over 300 projects such as Linyi People's Square and Qingdao Beach Park, with a cumulative laying area exceeding 500,000 square meters, and a customer repurchase rate of 85%.

FAQ: Technical Selection Guide for Square Hole Flooring
Q1: How to judge the environmental performance of square hole floor tiles?
A: Pay close attention to formaldehyde emissions and raw material composition. High-quality products should pass the EU CE certification or China's green environmental protection product certification, with formaldehyde emissions ≤0.05mg/m³. Linyi Xuan Cheng uses new PVC raw materials (non-recycled materials), adding natural calcium powder (content ≥60%), to eliminate harmful substances from the source.
Q2: What is the difference between co-extrusion and single-layer extrusion?
A: The co-extrusion process, through the composite of multiple materials, significantly improves product performance. For example, Linyi Xuancheng's five-layer co-extrusion structure achieves a surface wear resistance of over 8000 rotations (single-layer extrusion only 3000 rotations), and extends the aging resistance to 10 years (single-layer extrusion about 5 years).
Q3: How is the installation compatibility of square hole flooring ensured?
A: Focus on hole position accuracy and size stability. Linyi Xuancheng uses laser positioning technology to ensure hole position deviation ≤0.5mm, and controls the thermal expansion coefficient at 0.00002/℃ through the glass fiber reinforced layer, avoiding loosening due to temperature difference.

Full Summary: Scientific Selection, Avoid Technical Traps
The selection of square hole flooring requires a comprehensive consideration of environmental friendliness, technology, and installation compatibility. Linyi Xuan Cheng New Material Co., Ltd., with its five-layer co-extrusion technology, full-process automation production, and over 300 project application experiences, offers users a high-quality solution that is "not wood, but better than wood." By focusing on core parameters such as formaldehyde emission and hole position accuracy, and referring to the company's technical certifications and case studies, it can effectively avoid industry technical pitfalls and achieve the scientific application of green building materials.
