Kiosk Kouter in Ghent

The Kouter is a square in the center of the Flemish city of Ghent. Older names for this square are “Paardenmarkt”, and “Place d’Armes”. The square was traditionally used not only for all kinds of celebrations, but also for people’s congresses in the city. Since 1772, a flower market is held on Sundays. During the Ghent Festival is the location of the “Ball 1900”.

The Kouter  is surrounded by stately, mostly nineteenth-century buildings, including the Trade Stock Exchange.

In the square there is a late 19th-century cast-iron kiosk, built to a design by the Ghent architect Adolphe Pauli in 1878.  On Sunday, the kiosk served as a stage for concerts for the middle class and on Wednesday common people could also attend. In the 19th century there were six music kiosks in the center of Ghent, now there’s only two left.

In 1998 the kiosk was refurbished by the company IBT from Oosterzele. The entire structure was coated with a primer coat of ZINGA followed by a topcoat.


E.ON Power Station Plant

The power station of Langerlo was built in 1976, with two units powered by fuel oil. In 1986, the power station was converted to a coal power station, due to its proximity to the coal mines located in Genk. Since mining activity in Belgium declined and ceased in 1992 with the closing of the last mine in Zolder, the power station in Langerlo remained the last one driven by coal. In 1997 and 1999 the power station was enlarged. In 1999 the fume and gas purification was expanded and 2 gas turbines were built. Today the power station has a capacity of 556 MW, driven by a mix of coal, biomass(pellets) and gas.

For the expansion plans in 1997, ZINGA was prescribed for corrosion protection of 7500 m² construction steel by the engineering company Tractebel.
Even before, ZINGA was already a stock item at Electrabel companies for patch repair. Because of the expansion, several large beams turned out to be too big for HDG at local galvanisers’ baths and hence were treated with ZINGA.

The beams were coated with 2 x 60 μm DFT after steel fabrication at Victor Buyck to provide a good corrosion protection in a harsh industrial environment.
An inspection at the Power Station in 2014 (after 17 years), now run by Electricity company E.ON, found the beams in good condition showing no signs of corrosion and with a Zinc depletion of only 20 μm DFT.

Killybegs Immersed Pier Legs

The application of ZINGA on the pier legs at Killybegs Harbour was done in the summer of 2000.

The customer, the Irish Department of Marine and Natural Resources, and the contractor, SAR Marine & General, waited a full year before giving any official comment on the performance of the ZINGA coating.

Based on regular controls, they confirmed that the ZINGA is performing very well.

The fishing pier, which supports the factory buildings, is held up by 309 mild-steel hexagonal shaped legs, all approx. 600 mm in diameter.

These pier legs have been in the sea for 25 years and due to the salt and the sulphate reducing bacteria present in the sea water, they were losing up to 2 mm per year of their thickness. The waters around Killybegs are unique because they have the highest rate of corrosion in Europe.

The height from the concrete deck to the water level at low tide is approx. 3 to 4 meter.

At high tide, 1,5 to 2 meter of each pile is totally submersed in seawater.

The piles were prepared by UHP water-jetting and blasting to SA 2.5 with Rz 40 to 60 µm.

The application happened under severe surveillance of SGS Axa-Med, because it was a very difficult and delicate application as they had to take into account the tidal movement of the water and the constant contact with sea water. SGS Axa-Med had prescribed a dry film thickness of ZINGA of 25 + 40 + 40 + 40 µm = 145 µm, but in the end an average of 300 µm was measured.

Inspections in 2003, 2006 and 2009 confirmed that ZINGA is protecting the steel members very well in these harsh conditions.

In March 2014, the pier legs were hydro-blasted during an inspection. The shellfish/barnacles on the surface of the ZINGA layer have grown more than 100 mm in thickness in places, but the ZINGA underneath is still in perfect condition.
