Strong bearing capacity. During the experiment the product bearing 500KN pressure is not destroyed, carrying capacity is much better than the national standard (360KN). EN124 also comply with EU standards. Can withstand a variety of heavy-duty trucks rolling, effectively prevent accidents caused by falling covers produced. Sophisticated casting process so that products lines clear, covers a unique non-slip surface pattern, increasing friction, prevention of rain, snow, ice-covered pedestrians slipping. I designed manhole covers use of GB Atlas, there are: 97S501-1 portfolio (S501-1 ~ 2) single, double covers and stepping, 06ms201-6 / -7 / -8,02s501-2 covers double, single and double covers stepping, 05S518 gullies, 04S531-1 loess area water drains portfolio basis and interface description: ф500, ф600, ф700, ф800 light and heavy ductile iron and gray cast iron and seat covers. ф500, ф600 lightweight concrete manhole cover and support. Cast iron, steel stepping. Atlas Building Electric Installation Engineering - Design and Construction Materials episode (second edition) cable manholes common practice Fig double manhole covers design can be changed based on customer requirements, after spraying black asphalt to make products look bright, clean, resistant to oxidation and corrosion. QT500-7 ductile iron material, increasing the density of the product, so that the product has a strong compression. Bending, impact, heat, cold, abrasion, acid and alkali resistance, aging is not easy deformation characteristics. ..
