PMF/steel poles for public lighting, traffic signaling, road signing, camera observation systems and OCS electrification (light rail)

preservings

Almost all our poles will be produced from structural steel. Steel has to be protected to oxygen, salt and liquid. For a durable use of a steel object, this object has to be preserved. If there is no preserving, the nature will bring the steel object back to his original form: iron rust.

There are a couple variants to preserve a steel object. On this page, we only mention the most used preservings: hot dip galvanising, paintings, powdercoatings. Next to this, we will only mention the different corrosion protectors, which can be supplied on ground level and which will be used in our company.

hot dip galvanising
partij masten worden uit zinkbad getakeld In 1742, the French chemical Malouin discoverd that it was possible to protect steel against oxygen, salt and liquid by plunging the steel object in melted zinc: the process hot dip galvaning was born. In 1836, the chemical Sorel developed a proces to etch steel objects. The both technologies are still used in the current process of hot dip galvanising.

In the international norm EN-ISO 1461 is described the total process for hot dip galvanising. Before dipping a object in melted zinc (450°C), the object will be degreased, etched and fluxed (see picture below). The advantages of hot dip galvanising opposite other preservings, are:
- the total object will be plunged; the total surface will be protected (also the not visible parts) with a zinc surface.
- steel alloys with zinc; after removing the zinc surface, the alloy-ed surface will protect the steel object against rust.

alle stappen tijdens het verzinkproces

Hot dip galvanising is physical process. The composition of the used material (phosphor and silicium) and the wall thickness of the material will "decide" the zinc layer. In the respected norm EN ISO 1461, the minimum zin layer thicknesses and the average values are described for steel with the specified wall thicknesses. For additional information, we will refer you to the text of norm.

painting
If the total surface will be painted, then the steel object is also protected against oxygens, salt and liquids. If there is no contact between the steel surface and these three items, the steel object will not rust. At this moment, there are 1001 different paintings and systems and the quantity RAL-colors; for a good advise about the required painting, we will refer you to the professionals. For technical information about paintings, please follow the link to the website of Zandleven Coatings or International Coatings.

powder coating
You can get a protection against corossion also by powder coating. The powder will fix to the steel object by charging the object. In a oven, the steel object will be heated till 180°C. The powder will fix to the steel object and will harden to a high qualified preserving. A powder coating (also mentioned: polyester coating or thermo lacque) has better mechanical skills. Te surface of powder coating will be very smouthy: it looks nice and it is very easy to clean. The disadvantage is well known for repairing damages during transport and/or installing: the surface needs a correct treatment before painting.

duplex system
With a duplex system, the object will be hot dip galvanised and later the object will be painted or powder coated. We advise a lot of times a duplex system: hot dip galvanising for protecting against corrosion and improving the esthetical skills by supplying a painting or a powder coating).

corrosion protectiong on ground level
The part of a pole at ground level has to be protected against corrosion. We have urine from dogs, grass-mowers, road salt, etc. To protect your poles, we advise an additioan treatment on ground level. You can choose out of:
- environment friendly bitumen
- polyester sleeve
- asphalt sleeve
- shrink sleeve
- steel sleeve
- ceramic coating
Every type of sleeve has his own skills, advantages and disadvantages. We are happy ot inform you about the applicability in your sitauation.
