The blades of the pop up waste installation tool are made from spring steel. Spring steel has a high yield strength, which means that it can be bent, twisted or compressed significantly and still return to its original shape without being damaged or deformed.
The handle of the tool is made of steel with a zinc coating.
Applying a zinc coatings to iron or steel helps to prevent products from weather damage and corrosion. Zinc is a more reactive metal than iron or steel. The zinc coating will react with oxygen in the air to form a protective covering over the metal underneath.
