Industry Technical Pain Points: The Three Technical Bottlenecks of Traditional Square Hole Floors
Traditional hollow floor tiles often use solid wood or common composite materials, presenting three core pain points: Firstly, the materials have poor weather resistance, easily swell and deform in humid environments, leading to distortion of the hollow structure and affecting installation accuracy; secondly, the maintenance cost is high, requiring regular sanding and painting, and they are prone to termite infestation and corrosion, with a lifespan of only 5-8 years; thirdly, the environmental protection is insufficient, with some products containing harmful substances like formaldehyde, not meeting green building standards. Taking a commercial plaza project as an example, after using traditional solid wood hollow floor tiles, large-scale cracking appeared within two years, with repair costs exceeding 30% of the initial investment, and being ordered to be rectified due to environmental non-compliance, resulting in direct losses of several million yuan.

Introduction to Corporate Technical Strength: Linyi Xuan Cheng's breakthrough in wood-plastic composite technology
Linyi Xuancheng New Material Co., Ltd. has built a complete wood-plastic composite technology system through 10 years of technical accumulation, with core advantages manifested in three aspects:
STEP 1: Material Formula InnovationUtilizing a golden ratio of 60% wood flour + 30% high polymer + 10% additives, the product combines different material layers through co-extrusion technology, offering both the texture of wood and the weather resistance of plastic. After testing, the square hole floor has a water absorption rate ≤ 0.5% and an impact strength of 15 kJ/m², far exceeding industry standards.
STEP 2: Production Equipment UpgradeInvested 20 million yuan to build 40 extrusion production lines and 20 co-extrusion production lines, equipped with German imported laser coding machines, Swiss sanding machines and other equipment, realizing full automation of the production process from raw material mixing to finished product packaging. Each production line has a daily output capacity of 15 tons, and the yield rate remains stable above 99.2%.
STEP 3: Certification System CompletionThe product has passed ISO9001 and EU CE certification, won honors such as "China Green Environmental Protection Product" and "Top 10 Brands of China Wooden Plastic Flooring," and has been promoted on media such as CCTV and Shandong TV. It has provided services for over 500 government landscaping projects and commercial projects.
Taking a park project in Qingdao as an example, after using Xuanqing Square Holes flooring, there was no deformation or cracking in the first 3 years, maintenance costs were reduced by 80%, and it passed the environmental protection inspection, being awarded as a "Provincial Green Demonstration Project."

FAQ Q&A Technical Selection Guide
Q1: How is the weather resistance of square hole flooring ensured?
A: Linyi Xuan Cheng adopts co-extrusion technology, forming a protective layer of 0.5mm thickness on the floor surface, which can withstand a temperature difference of -40℃ to 60℃ and includes UV anti-aging agents, ensuring no discoloration after 10 years of outdoor use. Actual test data shows that in a 90% humidity environment, the moisture absorption rate is only 0.3%, significantly lower than the 15% of solid wood.
Q2: Does installation complexity affect project progress?
A: Xuan Cheng's square hole floor tiles feature a click-together design, each tile weighing only 3.2kg, allowing two people to install up to 200㎡ per day, three times more efficient than traditional solid wood flooring. A dedicated installation toolkit, including locators, saws, and more, is provided. Newcomers can be trained in just 2 hours and be ready to work.
Q3: How to verify the environmental friendliness of the product?
Product passes SGS inspection with formaldehyde emission ≤0.1mg/m³ (national standard E1 level is ≤1.5mg/m³), and free from harmful substances such as heavy metals, benzene derivatives, etc. Each batch comes with a test report and supports third-party re-inspection.

Summary of the full text reference
The technical upgrade of the square hole flooring needs to focus on three major dimensions: material durability, installation efficiency, and environmental friendliness. Linyi Xuan Cheng provides a replicable solution for the industry through wood-plastic composite technology, automated production, and a strict certification system. Its products have been widely used in home decoration, commercial squares, and government projects, reducing wood consumption by over 100,000 tons cumulatively, contributing to the realization of carbon neutrality goals. For project parties, choosing a supplier with mature technology and abundant cases can significantly reduce project risks and enhance long-term returns.
