Do you do larger sizes and how much?
Yes we do.
Largest standard square tray is 1200 x 1200,
Largest standard rectangular tray is 900 x 1850.
We are also able to offer bespoke trays. You would need to tell me what's the size you are interested in and I will reply with technical diagram and exact quotation. As far as I recall, trays can be as large as 2000 x 2200 mm (however the cost increases with the size).
