Galvanized inspection hole for gutter pipe Ф100mm

Inspection hole for gutter pipe with a diameter of 100 mm. The inspection opening provides access to the inside of the pipe without the need for disassembly. It is made of galvanized sheet metal.

Galvanized sheet metal is one of the most famous and widespread materials, thanks to its low price and high quality. It is not as resistant to corrosion as colored galvanized sheet metal, which is the only drawback of this material. To improve the quality of galvanized sheet metal, it is desirable to cover it with additional surface protection.
