About 5230AF expanded aluminium
5230AF is flattened expanded aluminium with a 40.6 x 17.8mm diamond and 4.04mm strands, giving 69% open area. We keep it in stock here in Bristol, 3mm thick, in 2500 x 1250mm sheets. Every sheet can be cut to size while you wait, and stock sheets go out on next working day delivery anywhere in the UK.
Flattened or raised?
Raised expanded metal is left as it comes off the expanding press, so the strands sit at an angle to the sheet. Flattened expanded metal is rolled after expanding, so the strands lie flat and the sheet has a smooth surface. 5230AF is flattened.
What do LWD and SWD mean?
LWD is the long way of the diamond and SWD is the short way, both measured centre to centre. The strand is the width of the metal between the openings.
