What are the advantages of ink-iron manhole cover customized processing materials?

In municipal road construction often see manhole covers, manhole cover is a safety facilities is often seen in our life, there are round and square, the material of cover, on the market at present most used or nodular cast iron manhole covers, see the name of the ductile iron manhole covers, is not very understanding.

Ductile iron manhole cover

In fact, the quality of ductile iron manhole covers are high quality, long service life, not only covers the toughness is better, compared with the ordinary iron manhole covers, corrosion resistance of ductile iron manhole covers, manhole covers are basically outdoor installation environment, whether it is windy rain will take over, if handled include corrosion resistant material, so after using for a long time, manhole covers, rust and corrosion causes covers safety performance greatly deteriorated.

The key is that it can guard against theft, no matter what kind of hat, safety is the most important, when a year because of the manhole cover loss damage is very big, the use of cast iron manhole covers advanced means of guard against theft, greatly reduces the manhole cover. Locks and keys are made of high hardness and anti-embroidered brass to prevent the lock from rusting during daily use.

Finally the bo tou tianlong casting ductile iron manhole covers, a relatively high value than strength of cast steel, cast iron, nodular cast iron manhole covers and compressive capacity, bending, impact resistant, heat resistant, cold resistant, wear resistance, acid and alkali resistant to ageing, not easy deformation, etc., bo tou tianlong casting ductile iron manhole covers not only has a big advantage, is the use of performance, also brought some benefits to the enterprise production.
