This D400 multileaf manhole cover and frame, with a 1060\u00a0\u00d7\u00a0700\u00a0mm clear opening, offers a robust, modular access solution engineered from premium ductile iron to meet demanding roadway environments. Its interconnected leaf design divides the cover into manageable sections, reducing individual lift weights while maintaining full Class\u00a0D400 (400\u00a0kN) loading capability for heavy\u2011traffic applications. Precision machining ensures a flush, non\u2011rock seating with three\u2011point suspension and a slip\u2011resistant surface, all protected by a durable bitumen coating. Fully compliant with BS\u00a0EN\u00a0124\u20112:2015 and backed by third\u2011party certification, this assembly blends safety, serviceability, and longevity in one authoritative package.<\/p>\n

Material & Modular Design<\/h2>\n

The cover and frame are cast from GGG500\/7\u2011grade ductile iron, delivering an optimal strength\u2011to\u2011weight ratio and superior impact resistance under cyclic loads.
Its multileaf (three\u2011leaf) configuration breaks the 1060 \u00d7 700 mm opening into smaller, interlocking sections, facilitating safer lifting and handling compared to single\u2011piece covers.<\/p>\n

Quality & Compliance<\/h2>\n

Manufactured and rigorously tested to BS EN 124\u20112:2015 for Group 4 (D400) covers and gratings.
Each unit bears third\u2011party certification, demonstrating full compliance with UK and EU regulations and ensuring traceable quality control.
Unlike composite alternatives, this ductile iron assembly maintains dimensional stability and longevity in extreme traffic conditions.<\/p>\n

Applications & Benefits<\/h2>\n

Ideal for carriageways, highways, airport aprons, industrial estates, and other high\u2011traffic zones that demand a 40 tonne load capacity.
The multileaf design and ergonomic three\u2011point suspension drastically reduce on\u2011site lifting effort, accelerating installation and maintenance while minimizing workforce strain.
A slip\u2011resistant surface pattern enhances pedestrian safety at crossings and edge zones, while the robust bitumen coating shields the assembly from corrosion, cutting lifecycle costs.
Backed by Highways England\u2013approved specifications, this cover meets enhanced safety and design standards for national road networks.<\/p>\n
