The core advantages include high-strength ductile iron material, which can withstand a maximum load of 400kN, meeting the passage requirements of heavy trucks. The integrated anti-theft locking device and special anti-theft bolts effectively prevent the cover from being stolen, reducing the loss caused by theft. The bituminous paint coating provides excellent anti-corrosion performance, and the surface has good anti-slip performance to avoid slipping accidents.
The standard sizes are 600×800mm and 700×900mm, with a plate thickness of 50mm. It adopts QT500-7 ductile iron material, which meets the EN 124 European standard. The surface is coated with bituminous paint to improve anti-corrosion performance. Each single piece weighs about 28kg, and it is equipped with special anti-theft bolts and locking devices to ensure safety and anti-theft performance.
This product is suitable for urban main roads, highway service areas, large freight parking lots, port terminals and other scenarios with high traffic load and anti-theft requirements. It can be used for rainwater trenches, sewage trenches and underground utility trenches, providing safe and reliable ground protection for heavy traffic engineering projects.
