Motor fuels and oils
Geberit Mapress Carbon Steel is suitable and approved for heating oil and diesel as well as motor, gearbox and lubricating oil.
Compressed air pipes
Geberit Mapress Carbon Steel can be used to distribute compressed air, depending on compressed air quality.
Benefits of Geberit Mapress Carbon Steel The perfect coating for every application
Geberit Mapress Carbon Steel pipes are available with PP-jacketing, outside zinc plating or inside and outside zinc plating.
Geberit Mapress Carbon Steel, outside zinc-plated: Zinc plating provides proven protection against external corrosion and makes the system particularly cost-effective. A robust solution for closed heating, cooling and industrial systems.
Geberit Mapress Carbon Steel, inside and outside zinc-plated: For maximum safety: Zinc plating on both sides ensures reliable protection against internal and external corrosion. Ideal for demanding applications such as sprinkler, extinguishing water and compressed air systems.
Geberit Mapress Carbon Steel with PP jacketing: The cream white PP jacketing provides reliable protection against external corrosion and ensures a clean and visually appealing surface-mounted installation. Ideal for visible pipe layouts, where function and look are equally important.
