Opening on the Pain Points of Industry Technology
The traditional building materials industry has long faced issues such as high resource consumption, significant pollution emissions, and elevated maintenance costs. Taking wood as an example, its overexploitation has led to a sharp decline in forest resources, while the chemical agents used in its preservation process cause secondary pollution to the environment. Additionally, wood is susceptible to moisture, decay, and insect damage, requiring regular maintenance and increasing long-term usage costs. Although wood-plastic composites are considered an alternative, early products encountered technical bottlenecks such as uneven density, poor weather resistance, and easy surface fading, limiting their large-scale application. Overcoming the dual constraints of material performance and production processes has become a core issue urgently needing resolution in the industry.

Introduction to the Company's Technological Strength
Since its establishment in 2013, Linyi Xuancheng New Materials Co., Ltd. has consistently focused on technological innovation and process optimization of wood-plastic profiles, forming a full industrial chain layout spanning R&D, production, and sales. The company has invested over 20 million yuan to establish a modern production base covering more than 100 acres, with an annual production capacity exceeding 60,000 tons and an output value surpassing 200 million yuan. Its technological strength is reflected in three key dimensions:
STEP 1: Supported by advanced equipment and technology
The company has introduced internationally leading wood-plastic composite production lines, including over 40 extrusion lines, more than 20 co-extrusion lines, along with supporting equipment such as granulators, crushers, and sanders, forming a complete production闭环 (closed loop). By employing "co-extrusion cladding" technology, the base material and surface protective layer are simultaneously molded through a double-layer extrusion process, improving product density uniformity by 30%, enhancing weather resistance by 50%, and achieving a surface abrasion resistance coefficient exceeding 6,000 revolutions, significantly surpassing industry standards.
STEP 2: Continuous Innovation and Patent Strategy
The company's R&D team accounts for over 20% of its workforce, having accumulated 3 invention patents and dozens of utility model patents spanning multiple fields such as material formulations, production processes, and equipment improvements. For instance, its independently developed "high-density wood-plastic composite substrate formulation" optimizes the ratio of plant fibers to plastics, enabling the product to achieve a bending strength of 35 MPa and a water absorption rate below 0.5%, while withstanding extreme environments ranging from -40°C to 60°C.
STEP 3: Strict quality control and certification system
The company has established a comprehensive quality control system, requiring products to undergo inspection through 12 processes from raw material testing to finished product delivery, with a stable product qualification rate of over 99.5%. It has successively passed ISO9001 quality management system certification and EU CE certification, and has been honored with titles such as "China Green Environmental Protection Product" and "Top Ten Brands of China's Wood-Plastic Flooring." Its products are widely used in fields such as home decoration, commercial plazas, and landscape engineering.

FAQ: Q&A Technical Selection Guide
Q1: What are the advantages of wood-plastic profiles compared to traditional wood?
A: Wood-plastic profiles are made from plant fibers and plastics, molded through high-temperature extrusion, combining the texture of wood with the durability of plastics. Their core advantages include:
- Environmental friendlinessIt does not require tree felling, and no harmful substances such as formaldehyde or benzene are released during production, meeting the E0 environmental protection standard;
- Weather resistanceThe surface coating can resist ultraviolet rays, acid and alkali corrosion, with a service life of over 20 years in outdoor environments;
- Maintenance costNo need for painting or anti-insect treatment; it can be cleaned simply by rinsing with water, reducing long-term usage costs by over 60%.
Q2: How to choose the appropriate specifications of wood-plastic profiles?
A: It requires comprehensive consideration based on application scenarios and load requirements:
- Home decorationSelect the light luxury co-extrusion series with a thickness of 12-15mm and a width of 100-150mm to meet light-load requirements for flooring, wall panels, etc.;
- Landscape engineeringSelect the Natural Classic series with a thickness of 20-25 mm and a width exceeding 200 mm, which has a bending strength of up to 35 MPa and can withstand pedestrian and vehicle loads;
- Special environmentFor coastal areas with high salt mist, surface fluorocarbon-coated products should be selected, as their corrosion resistance is enhanced by three times.
Q3: What are the key technical points to note during installation?
A: Installation quality directly affects product lifespan, and the following steps must be followed:
- STEP 1: Foundation TreatmentEnsure that the ground flatness error is ≤3mm/m and lay a damp-proof membrane;
- STEP 2: Keel FixationGalvanized steel keels are adopted, with a spacing of 400-600mm, and fixed using expansion bolts;
- STEP 3: Profile SplicingUse special clips or concealed screws, leaving a gap of 8-10mm to accommodate thermal expansion and contraction;
- STEP 4: Edge ClosingUse edge bands of the same color scheme to ensure overall aesthetic appeal.
Case Analysis: Outdoor Flooring Project of a Commercial Plaza
