HERMEQ’s Highway D400 Manhole Cover is a high-performance surface access cover engineered for U.S. roadways including highways, A-roads, and busy traffic routes. Manufactured from ductile iron and certified to CD 534 and BS EN 124:2015, this cover supports continuous HGV traffic and long-term use.

Its reinforced geometry distributes axle loads evenly to reduce substrate damage and edge spalling, extending road life and lowering maintenance costs. The chequered top provides anti-slip grip with a verified PSRV of 70+, tested by a UKAS-accredited lab. Mechanical lift points and indexed corners support safe and consistent installation.

  • Certified to CD 534 + BS EN 124:2015 – Road-legal and compliant with highway-grade requirements
  • Anti-slip PSRV 70+ surface – Safer for wet weather braking and turning
  • Reinforced corners – Reduces stress on asphalt or concrete pads
  • Mechanical lift notches – Allows safe, repeatable manual or machine access

Ideal for DOT-compliant infrastructure projects, telecom vaults, utility chamber covers, and municipal road upgrades where structural integrity and access safety are paramount. Available in five rectangular sizes.

HERMEQ also stocks a wide range of Road Plates, Trench Covers, and Access Mats that meet OSHA and DOT expectations.
