PP-R concrete protection panels for Canada's leading galvanizer

Our company has once again demonstrated its outstanding plastics expertise. The Canadian company Corbec is a leader in the field of hot-dip galvanizing. AGRU was able to ensure the operational safety of the new hot-dip galvanizing plant by supplying AGRU Utra-Grip concrete protective liners in PP-R. PP-R is temperature and media resistant and extends the service life of the pre-treatment tanks many times over.

Hot-dip galvanizing is a process in which steel is coated by immersing it in molten zinc to provide corrosion protection. The latest plant of the family-owned company, founded in 1965, was built in Ontario and was equipped with state-of-the-art plant technology by our long-standing customer HESON. Before the workpieces are coated with molten zinc at 450 degrees, they undergo a series of pre-treatment baths with hot acids and alkalis. To protect the concrete structure in the new plant, a total of fifteen in-situ concrete tanks in the pre-treatment plant were lined with 8 mm thick AGRUSure Grip PP-R concrete protective liners. This measure ensures effective protection against the aggressive and high-temperature production liquids.


Safety handrails made of PP pipes also provide the necessary occupational safety.


In addition, other areas of the production facility, such as the entrance area of the transfer car, the rail area and the production area, were also protected with AGRU products. A total of 1887 m2 of wall and ceiling surfaces were lined with semi-finished sheets to ensure maximum corrosion resistance. 

Significant extension of service life

The use of AGRU-Sure Grip PP-R concrete protective liners significantly extends the service life of the concrete structures and increases the operational reliability of the entire plant. For Corbec, this means not only long-term cost savings, but also increased efficiency and reliability in production. The successful implementation of this project was the result of close cooperation between HESON and the local installation company, supported by an experienced site manager from Austria. The PP-R BSP tanks were installed on site using extrusion welding. With this project, AGRU has once again demonstrated that our products and solutions meet the highest requirements and make a significant contribution to improving industrial processes. AGRU's concrete protection systems are a decisive factor for the longevity and efficiency of modern production facilities.
