1. Burglarproof
2. Sound proof
Non-noise, and environment protection. After the lathe machining, the top and the base can be inosculation tightly, eliminating noise when vehicles passing.
3. Falling-proof
Have good compression bearing. Our products can bear 400KN and not be destoryed, and which is greatly better than the national standards (240KN), and the power supply bureau standards (360KN). It can bears all kinds of heavy trucks rolling, and can prevent accident of the cover falling.
4. Nonslip
The excellent casting technics makes the lines of covers clear, increasing friction, and guarding against passerby slide into road for the covering of rain, snow, and ice.
5. Nice appreance
Exquisite workmanship, clear, smoothly, well-distributed, non-air blister, zero defects, legibility, and black bitumen coated, making the product brightness, antioxidant, and corrosion attack.
6. Top-grade material
Adopting ductile iron casting craft, we improve the density of products, making them have the following advantages: Strong anti-pressure, bending and impact resistence, heat/cold-proof, anti-friction, and so on.
We are the professional manufacturer of manhole cover, grating, floor drain, pipe fittings. Our products had been exported to Southern Africa, North Africa, Middle East, Korea, Japan and other countries and areas for many years. We own a batch of talented technicians with professional casting technology, and the perfect inspection equipments. Our company passed ISO9001: 2000 and enjoy good reputation.
