Our standard lead time is 10-14 days from order. This can vary slightly depending on the product but we try to hold a large stock of standard coloured products to ensure leads times are kept to a minimum. Custom colours, especially on aluminium do carry extended lead times due to the nature of the powder coating processes and supplier lead times which is out of our control.
