Working with Aluzinc
If possible, avoid writing on the sheets using a felt-tip or a thick lead pencil, as it will be very difficult to remove the marks. Moreover, the graphite in pencils may damage Aluzinc.
Try to minimise cutting by using sheets already cut to size. If cutting is inevitable, it is preferable to cut the sheets on the ground, if possible using a nibbler or a power chain saw, which are both highly suitable for this kind of work.
It is essential to ensure that the ground is clean, or that it is covered in some way (e.g. with a tarpaulin or board) to prevent the sheets touching the ground. Cold shearing is preferable to flame-cutting or abrasive cutting.
Aluzinc can be welded like most other metallic coated products. Nevertheless,
the welding parameters should be adjusted to match its specific properties. Several welding techniques may be used (high/low frequency, spot, laser, seam etc), but the best option is arc welding.
Although Aluzinc can be easily welded, welding should not be confused with brazing.
The difference is that in brazing, the sheets are not joined by melting the steel but by applying a tin-lead alloy or a silver-based alloy (high-temperature brazing).
Regardless of the option considered, brazing is highly inadvisable!
It is advisable to affix the sheet using stainless steel, nylon, aluminium or, in the best-case scenario, Aluzinc. The fasteners and screws must also be compatible with Aluzinc (identical corrosion resistance).
SSAB/Aluzinc banding is manufactured using our ‘185AZ Grade Aluzinc’ making it ideal for securing Aluzinc sheets and insulated pipework jacketing as use in the petrochemical and chemical industries as well as HVAC applications.
- 0.7mm x 19mm (3/4inch) wide in 25kg (250 metres) coils from stock (Other widths and coil lengths available to order)
- Good abrasion resistance.
- All deliveries are supplied palletised and shrink-wrapped.
- Aluzinc Banding clips available (100% compatibility with our Aluzinc banding).
This is now fairly standard in the building sector and is very practical in some cases, as it avoids subsequent repair of the surfaces.
For Aluzinc, we recommend using EPOXIES (for structural applications) or POLYURETHANES (for domestic applications and in mild environments).
Be careful with sealants that release acetic acid as they cure, as there is a risk that Aluzinc will be attacked.
So make sure you carefully read the composition of the product used!
After being installed, Aluzinc can easily be painted for aesthetic reasons.
We recommend that you contact the paint manufacturer to find out whether the paint to be used is compatible with the properties of the Organic Anti-Fingerprint coating
