Corrosion protection for the steel construction of a gymnasium
Task:
Protection for joints especially at risk of corrosion damage that cannot be reached with common corrosion protection agents.
Special Challenge:
The area at risk of corrosion cannot be accessed. The material used must be able to creep over distances of several centimetres.
Solution:
We use our corrosion protection grease TimeMAX 1000 which has a high capability of creep.
Advantage:
During summer heat the grease creeps into the gap at risk.
In spring 2006 we were hired to protect the construction of a new gymnasium in Hamburg from corrosion. After the construction of the hall first traces of corrosion had been found in the 22 support columns. Reason: during the assembly the zinc spraying of almost all columns had been damaged.
The gap, which is difficult to reach, is only eight millimetres wide. We were awarded the contract because our corrosion protection grease has extreme capability of creep and can creep deeply into the gap.
Those responsible from the city and the contractor knew: if the corrosion on the inside is not stopped the whole construction will have to be taken apart again in a few years.
After the treatment in 2006 we agreed with our customer to have a look at the support columns in 10 to 12 years time. We were to check if reworking might be necessary.
Conclusion after 11 years: Even at short distance no efflorescence is visible. Corrosion was stopped effectively.
