From Inquiry to Shipment
Three steps, no surprises. You always know where your order stands.
Drawing, standard, size, class and quantity. A spec sheet or even a photo of the nameplate works.
You get prices, lead time and packing plan in writing. Payment terms agreed before production starts.
We inspect, pack and ship, then send the full document set: invoice, packing list and material certificates.
Checked at the Mill, Checked Again Before Packing
Every order is inspected twice: once at the producing mill, and again at our warehouse before the cases are closed. Dimensions, markings and surface condition are all verified against your specification.
The document set ships with the goods, so what you ordered is exactly what you receive – and you can prove it to your end client.
