Class D400
D400 is a load classification defined under BS EN 124 for access covers and gratings. Products in this class are designed to withstand a test load of 400 kN, making them suitable for areas subject to heavy traffic, such as carriageways, hard shoulders, and industrial roads. Typically manufactured from robust materials like ductile iron, D400 gratings provide exceptional strength, stability, and resistance to impact, ensuring long-term performance in demanding environments. This classification guarantees compliance with stringent safety and durability standards for highway and urban drainage applications.
