Key Features
- High-Density Polyethylene (HDPE) Construction: Engineered from premium-grade PE resin, offering exceptional chemical resistance, UV stability, and impact strength for long-term durability in harsh environments.
- Customizable Dimensions & Profiles: Precision extrusion enables tailored channel widths (10–100mm), depths (5–50mm), and lengths (up to 6m) with tight tolerances (±0.15mm) to meet specific architectural requirements.
- Integrated Grating Options: Compatible with stainless steel, aluminum, or polymer grates for load ratings up to 9000 lbs (Class D per EN 1433), ideal for pedestrian and vehicular traffic zones.
- Seamless Jointing System: Pre-engineered end connectors and gaskets ensure leak-proof installations, reducing on-site assembly time by up to 40%.
- Thermal & Acoustic Insulation: Closed-cell structure provides inherent thermal resistance (R-value: 3.2/inch) and noise reduction, critical for interior applications.
- Compliance & Certifications: Meets ASTM D3350, ISO 1183, and EN 12056 standards; available in fire-retardant (UL94 V-0) and anti-static variants.
Technical Specifications
Material Properties
Manufactured from HDPE (High-Density Polyethylene), this channel strip combines a density range of 0.941–0.965 g/cm³ with a tensile strength of 3,000–4,000 psi (20–28 MPa). The material exhibits excellent resistance to acids, alkalis, and solvents (pH 1–14), with a continuous service temperature range of -50°C to 80°C. For specialized environments, alternative materials like UPVC (rigidity, 1.3–1.45 g/cm³) or ABS (impact strength, 200–300 J/m) are available upon request.
Design & Performance
Channels feature a smooth inner wall (Ra ≤ 1.6 μm) to minimize friction (Manning’s coefficient: 0.009) and maximize flow efficiency. Wall thickness ranges from 2.5–8mm, supporting structural loads up to 500 kg/m². Customizable slope gradients (0.5%–3%) and integrated overflow ports ensure compliance with drainage regulations.
Applications
- Architectural Drainage: Roof terraces, balconies, and plaza decks with integrated water management systems.
- Commercial Infrastructure: Shopping malls, airports, and stadiums requiring high-capacity, low-maintenance drainage.
- Industrial & Municipal: Parking garages, wastewater treatment plants, and roadways with corrosive runoff.
- Green Building Projects: LEED-certified developments leveraging recyclable PE (90% post-industrial content).
