Alu-zinc AZ150

​

Alu-zinc is a aluminium-zinc coated steel sheet that can be used unpainted up to corrosive class C3. The coating alloy consists of:

• 55% Aluminium

• 43.4% Zinc

• 1.6% Silica

​

The name AZ150 indicates the coat weight of 150 g/m2 per double side.

The surface has been treated with SPT (Surface Protection Treatment) to prevent stains during handling and to ease shaping.

​

APPEARANCE

​

The surface is initially glossy metal with a rose pattern but after some time it turns greyish, and eventually it becomes matt grey.

​

TRIMMING EDGES

Normally, the trimmed edges do not need to be painted but in corrosive environments in which the trimmed edges are aesthetically prominent a protective paint is recommended to be applied.
