MAXI-TUBE® can be painted and powder coated like other zinc coated products, providing a duplex coat. It is manufactured from pre-coated coil which has a spangle free engineered surface providing a smooth and uniform finish for top coating.
The pre-coated surface is produced under precisely controlled conditions and is regarded as an engineered material coating. The passivation of the MAXI-TUBE® coating further protects the surface which provides a high quality finish for approved powder coat or paint systems. This ensures high quality adhesion of paint coatings to MAXI-TUBE®. Painted or powder coated MAXI-TUBE® provides a high durability specification alternative.
