As the registered and patented product of baz Macit Boru, in the classical deep well column pipe you have been using until today, we have achieved to obtain the sealing always wanted but could not be provided until today due to the rubber seal indented without sawdust rising by the technique of rubbing the dipped galvanize coated passes completely in world standarts with its thick sleeve solid in interior and exterior ensuring high resistance against corrosion developed with the latest technology. By virtue of this, the life of the product has increased many times more. As known, there is no material which can resist water leaked with high pressure. However this is only one of the properties of the product, another property of it is its polyethylene coating of which we will appreciate the value much better after years. This is the solid coating applied for the first time in the world. Because the outer surface of the pipe including the sleeve part is completely insulated bu polyethylene coating and the relationship of the metal with outer effects is completely cut, and the pipe which is already galvanize coated has no water, soil etc. contact, the problem of corrosion, rusting and breaking is completely eliminated due to the proven noncorrosive property of polyethylene material.
