Production to order
There is no minimum order quantity. Where an item and its processing carry a minimum production run, that is stated in the quotation rather than discovered after the order.
International standards
Production runs to international standards such as ASTM, EN, JIS and GB for the various grades of aluminium product, with IEC and BIS practice applied where the order calls for it.
Edge condition as a specification
Every roll is checked so that it carries no burrs and no scratches and has a round edge suited to transformer winding.
Freight that suits the job
Sea, air and land transport. Lead time is normally 10 to 30 days depending on the order, and the warranty period is 12 months after delivery.

Choosing Between Foil, Strip and Rectangular Wire
Three conductor formats, three different winding problems. This is how the choice is normally made and what each format costs you elsewhere in the design.

Width to the coil dimension, edges rounded, no burrs and no scratches - because the burr is what causes the turn-to-turn fault three weeks after delivery.

A coil damaged in transit is a coil you cannot wind. Packing is specified as part of the order, not left to the shipping department.
