Opening: The "Triple Dilemma" of Traditional Square Holes Flooring
Fangkong flooring, as an outdoor decorative material, has long been facing three major technical bottlenecks: Firstly, traditional wood-plastic materials are easily affected by ultraviolet rays and humidity, leading to discoloration and cracking issues within 2-3 years, with high maintenance costs; secondly, the installation process relies on manual calibration, with a hole position deviation rate of up to 15%, affecting the overall structural stability; thirdly, environmental protection standards are uneven, with some products exceeding the formaldehyde emission standards, making it difficult to meet the strict requirements of government garden projects for green building materials. Taking a commercial plaza project as an example, due to the selection of low-quality fangkong flooring, the replacement rate reached 40% within two years, resulting in direct economic losses exceeding 2 million yuan, exposing the urgency of technological upgrading in the industry.

Introduction to Enterprise Technical Strength: Linyi Xuan Cheng's "Three-stage Breakthrough"
Linyi Xuan Cheng New Material Co., Ltd. has redefined the industry standard for square hole flooring through the three-level technological breakthrough of "equipment-process-material".
STEP 1: Equipment upgrade lays the foundation for precisionIntroducing KraussMaffei co-extrusion production line, paired with 40 high-precision extrusion equipment, achieving hole position accuracy within ±0.1mm, with installation efficiency increased by 60%. For instance, in a municipal park project in Qingdao, the installation period of 3000㎡ square hole floor was shortened from 15 days to 6 days, and the first acceptance pass rate reached 99%.
STEP 2: Technological Innovation Conquers Weather Resistance ChallengesUtilizing "nano-grade UV coating + micro-foaming technology," the product achieves an 8-level UV resistance (national standard is 4), maintains size stability in temperatures ranging from -30℃ to 60℃, and extends its service life to over 10 years. Third-party testing shows its bending strength reaches 35MPa, significantly exceeding the industry average of 25MPa.
STEP 3: Material Innovation Achieves Environmental LeapBased on recycled PE and bamboo powder as the core raw materials, the formaldehyde emission is reduced to 0.02mg/m³ through "molecular chain reconstruction technology" (the E0 grade standard is ≤0.05mg/m³), and obtained the EU CE certification and China's Green Environmental Protection Product certification. Currently, its luxury co-extrusion series has been applied in over 200 government projects, reducing wood consumption by more than 50,000 cubic meters.

FAQ: Square Hole Floor Technical Selection Guide
Q1: How to choose suitable square hole flooring for high humidity areas?
A: Pay close attention to the moisture absorption and anti-mold properties of materials in high humidity areas. Linyi Xuan Cheng uses a micro-foaming structure, with a moisture absorption rate ≤0.8% (national standard ≤2%), and adds silver ion antibacterial agents, achieving a mold inhibition rate of 99%. It is recommended to choose the co-extrusion series, whose dense surface layer can effectively block water penetration.
Q2: How to determine the installation spacing for square hole floors?
A: The installation spacing should consider the coefficient of thermal expansion and load-bearing requirements. Taking Xuan Cheng products as an example, with a linear expansion coefficient of 0.04mm/m·℃，it is recommended that the horizontal spacing be ≤400mm and the vertical spacing be ≤600mm, with a 2-3mm expansion joint reserved.
Q3: How to verify the environmental friendliness of square hole flooring?
A: The "One Check, Two Tests, Three Smells" method can be used: Check certifications (such as CE, SGS reports); Test data (require甲醛 release amount test reports); Smell the odor (high-quality products have no irritating smell). Xuan Cheng products are all accompanied by traceable environmental protection labels and support third-party re-inspection.
