Architects specify aluminium when the panel is carried on a light frame. Fabricators specify mild steel when someone will stand on it or strike it. The hole pattern can be identical. The blank is not.
Where aluminium is the right blank
Facades, false ceilings, sunscreens, HVAC grilles and decorative screens. It is light, it takes a powder coat, and it does not rust the way bare MS does. Copper and brass are the other architectural metals, on their own catalogues, when the look has to be that metal rather than a coated aluminium.
Where it is the wrong blank
Walkway grating, a vibrating screen and a heavy machine guard. Those jobs start in mild steel, GI or stainless, at a thickness chosen for the load. Putting the same pattern number on aluminium does not make the panel structural.
The order line
Pattern number or hole, pitch and angle. Then aluminium, thickness in millimetres, sheet size, and blank edge if the frame needs a solid border. Alloy or temper only if the consultant has written one. If they have not, we confirm it on the quote rather than invent a grade.
