Why Luzhongbao 500×340×80 Composite Single Grate Has Become the Preferred Choice for Municipal Drainage Engineering
With urban drainage systems developing towards refinement and high efficiency today, drainage grates, as key components of stormwater collection systems, directly impact urban waterlogging prevention effectiveness and road traffic safety. Traditional drainage grates commonly face pain points during long-term use such as insufficient load-bearing capacity, susceptibility to clogging, and poor durability, while ordinary composite grates often suffer from early damage due to unreasonable structural design. The Luzhongbao 500×340×80 Composite Single Grate, based on advanced composite material technology and structural engineering innovation, successfully breaks through the technical bottlenecks of traditional drainage facilities through optimized drainage hole layout and an enhanced support system, and has now become the preferred choice for locations such as urban arterial roads, residential areas, and commercial plazas.
This product strictly complies with the GB/T23858 standard and is manufactured using high-performance composite materials and precision compression molding technology. The 500mm × 340mm rectangular dimensions are optimized through fluid dynamics simulation, achieving optimal structural stability while ensuring drainage efficiency. The 80mm thickened design, combined with the internally three-dimensionally distributed reinforcement rib network, significantly enhances the product's load-bearing capacity and impact resistance. The product surface uses a deep-tooth anti-slip pattern design, with a friction coefficient exceeding 85 BPN, and undergoes special UV resistance treatment, ensuring long-term performance under harsh climatic conditions.
Material System and Manufacturing Process
The Luzhongbao Composite Single Grate selects high-performance unsaturated polyester resin as the matrix and continuous glass fiber as the reinforcement material. Scientific formula design gives the product both excellent mechanical properties and corrosion resistance. The manufacturing process employs a computer-controlled hydraulic molding system. Precisely regulated temperature, pressure, and time parameters ensure thorough material curing and a dense, uniform internal structure. Unique mold design gives the product precise dimensional tolerances and smooth surface quality after demolding.
Structural Design and Drainage Performance
The structural design of this single grate fully considers the balance between drainage efficiency and structural strength. The interior uses a clearly prioritized primary and secondary reinforcement rib layout, with a dense support network installed in key stress areas, effectively enhancing the product's load-bearing capacity. The drainage hole design is based on fluid dynamics principles, employing a gradually expanding hole structure that ensures maximum drainage efficiency while effectively preventing clogging by debris. Laboratory tests show the drainage efficiency of this product reaches the leading level among similar products.
Load-Bearing Performance and Safety Features
The product load-bearing class reaches the D400 standard, with a test load exceeding 400 kN, fully meeting the usage requirements for urban roads. The surface anti-slip pattern combines raised dots and linear grooves in a three-dimensional design, ensuring reliable anti-slip assurance even in rainy or snowy conditions. The grate body and frame use a multi-point buckle connection system, ensuring installation stability while facilitating later maintenance and cleaning.
Durability and Environmental Adaptability
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 anti-aging agents and UV absorbers, the product's service life in outdoor environments can exceed 30 years. The special formula design also gives the product good temperature resistance, enabling it to adapt to environmental temperature changes from -40°C to 80°C.
Construction Convenience and Economic Benefits
The modular design makes the installation process simple and efficient, with installation time per unit not exceeding 20 minutes. Precise dimensional control ensures a perfect fit with standard frames, greatly improving construction efficiency. 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 40% compared to traditional products.
Application Scenarios and Adaptation Performance
The standard 500×340×80mm size adapts to various municipal drainage needs, being particularly suitable for heavy-duty areas like roadways and parking lots. 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 500×340×80 Composite Single Grate, with its innovative structural design, exceptional load-bearing performance, excellent service life, 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 advanced design concept and reliable performance, provides strong 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 widespread recognition in the market competition.
