Why Luzhongbao 500×320×50 Composite Single Grate Has Become the Preferred Choice for Municipal Drainage Engineering
In the construction of modern urban drainage systems, drainage grates, as the first line of defense for stormwater collection, directly impact the efficiency of urban flood control and drainage, as well as road traffic safety. Traditional cast iron drainage grates have long faced problems such as susceptibility to theft, poor corrosion resistance, and insufficient drainage efficiency, while ordinary composite grates often suffer from deformation and damage due to inadequate structural strength. The Luzhongbao 500×320×50 Composite Single Grate, based on high-performance composite materials and innovative structural design, successfully solves the technical pain points of traditional drainage facilities through scientific drainage hole arrangement and a reinforced support system, and has now become the ideal choice for locations such as sidewalks, residential roads, and plazas.
This product strictly complies with the GB/T23858 standard and is precision compression-molded using high-performance composite materials. The 500mm × 320mm rectangular dimensions are optimized through fluid dynamics, achieving optimal structural stability while ensuring drainage efficiency. The reasonable 50mm thickness, combined with the internally three-dimensionally distributed reinforcement rib network, ensures sufficient load-bearing strength while achieving optimal material utilization. The product surface features a deep anti-slip pattern design, with a friction coefficient exceeding 80 BPN, and undergoes special UV resistance treatment, ensuring long-term durability in outdoor environments.
Material Advantages and Process Innovation
The Luzhongbao Composite Single Grate selects a high-performance composite material system. The matrix uses unsaturated polyester resin, and the reinforcement material employs continuous glass fibers. This material combination gives the product both excellent mechanical properties and corrosion resistance. Its tensile strength exceeds 150 MPa, and its flexural strength exceeds 200 MPa. The manufacturing process uses a 10,000-ton hydraulic press for compression molding. Precisely controlled temperature and pressure parameters ensure a dense internal structure and excellent dimensional stability.
Structural Design and Drainage Performance
The internal structure of this single grate is optimized through Finite Element Analysis, adopting a crisscrossing reinforcement rib layout to form a stable spatial load-bearing system. The drainage hole design is simulated through Computational Fluid Dynamics, employing a gradually expanding hole structure that ensures maximum drainage efficiency while effectively preventing clogging by debris. Laboratory tests show that this product maintains over 95% drainage efficiency even when rainfall intensity reaches 150 mm/h, far exceeding national standard requirements.
Load-Bearing Performance and Safety Features
The product load-bearing class reaches the C250 standard, with a test load exceeding 250 kN, fully meeting the usage requirements for urban roads. The surface anti-slip pattern consists of raised points and grooves forming a three-dimensional structure, ensuring pedestrian safety in rainy or snowy weather. The grate body and frame use a three-point buckle connection, ensuring installation stability while facilitating later maintenance and cleaning. A special edge chamfer design effectively avoids noise issues during vehicle passage, enhancing user comfort.
Durability and Anti-Corrosion Characteristics
The inherent corrosion resistance of the composite material enables the product to resist erosion from chemicals such as rainwater and de-icing agents. By adding UV inhibitors and antioxidants, the product's service life in outdoor environments can exceed 30 years. The unique formula design also gives the product good anti-aging performance, resisting embrittlement and fading during long-term use.
Construction Convenience and Economic Benefits
The modular design makes the installation process simple and efficient, with installation time per unit not exceeding 15 minutes. Precise dimensional control ensures a perfect fit with standard frames, requiring no on-site adjustments. From a whole-life-cycle cost analysis, the product's ultra-long service life and extremely low maintenance requirements reduce the comprehensive cost of use by over 35% compared to traditional products. According to engineering statistics, after adopting this single grate, maintenance frequency is significantly reduced, effectively saving operation and maintenance costs.
Application Scenarios and Adaptation Performance
The standard 500×320×50mm size adapts to various municipal drainage needs, being particularly suitable for locations such as sidewalks, residential roads, and plazas. The product can be customized in different colors according to actual needs, meeting the requirements of special environments. Its refined appearance design harmonizes with the surrounding environment, enhancing the overall landscape effect while meeting functional demands.
Summary
The Luzhongbao 500×320×50 Composite Single Grate, with its excellent material properties, scientific drainage design, reliable load-bearing capacity, and significant economic benefits, has become the preferred solution for modern urban drainage construction. This product not only solves the technical defects existing in traditional drainage facilities but also, with its innovative design concept and exceptional performance, provides reliable assurance for the efficient operation of urban drainage systems. Choosing this product means injecting lasting quality assurance and value return into the engineering project, which is the fundamental reason for its continued recognition in the market competition.
