Product Overview
The LWLSC2001 Heavy-Duty Ductile Iron Manhole Cover / Trench Grating is engineered for high-performance drainage and utility access in demanding municipal and industrial environments. Manufactured from premium grade ductile iron (ISO1083/JS/500-7), this linear cover combines high tensile strength with exceptional impact resistance.
Designed to meet EN 124 D400 standards, this unit can safely bear test loads of up to 400 kN (40 tons), making it ideal for carriageways, arterial roads, logistics parks, and parking areas subjected to heavy-wheel traffic.

Key Features & Advantages
High Strength-to-Weight Ratio: Spheroidal graphite iron structure offers superior ductility and load capacity compared to traditional grey cast iron without excessive weight.
Anti-Slip Safety Surface: Specially textured non-skid pattern provides secure vehicle traction and pedestrian safety even in wet conditions.
Corrosion & Weather Resistance: Coated with high-grade black bitumen paint, offering long-term protection against moisture, road salts, and chemical corrosion.
Interlocking & Modular Design: Multi-point side brackets/ears allow easy linear alignment, stable anchoring into concrete trench walls, and secure continuous installation.
Anti-Rattle & Stability: Precise casting minimizes road chatter, shifting, and noise pollution under fast-moving vehicle loads.
Recommended Applications
Main traffic carriageways and highways (Class D400 zones)
Industrial estates, freight terminals, and logistics hubs
Commercial parking facilities and gas stations
Urban linear drainage systems and underground utility trenches
Airport airside/apron peripheral service roads
