Product Description

Painted Aluminium for rainwater gutter

Coil sheet coating makes use of a simple, but effective principle, i.e. to clean, pretreat and coat flat coils or sheets of steel or aluminium in a continuous operation, before other stages of industrial manufacture [1-4]. The slogan for this concept is: Finish first - fabricate later!

The aluminium alloy and temper has been specially selected for guttering, with forming properties meeting the needs of the machines used for gutter profile and presses used for the accessories. Commonly used alloys are in the 3000-series, mainly in the 3105 and 3003 range. The coil is usually coated on both sides with the same coating system but often in different colour combinations. This allows the customer the flexibility to select either colour for the decorative face of the installation, whilst at the same time giving added performance on the inside of the gutter.

The coating type and gauge selected is a balance between cost effectiveness and performance. The service life is dependent on many factors, including conditions of exposure, cleaning and keeping the surface free from prolonged contact with incompatible materials. Maintenance painting at the appropriate time, serves to prolong the service life of the guttering systems.
 Chalco Coat 's unique pre-treatment is used prior to the primer and topcoat paint system. The pre-treatment is an alternating current anodizing in sulphuric acid electrolyte. The process produces a clean surface with a thin aluminium oxide film. This film is an integral part of the aluminium surface and is flexible due to its porous structure. This pre-treatment prepares the surface for excellent paint adhesion and corrosion resistance of the painted products. The pre-treatment is non-toxic and does not contain any chromium or heavy metal based chemicals and, therefore, underlines Chalco Coat's environmental friendly profile.

The coating type is selected from one of the following:
•Chalco Coat 1100 PE Thickness 0.3mm--1.0mm temper H14
•Chalco Coat 1100 PVDF Thickness 0.3mm--1.0mm temper H14
•Chalco Coat 3003 PE Thickness 0.3mm--1.0mm temper H14
•Chalco Coat 3003 PVDF Thickness 0.3mm--1.0mm temper H14
