Mill Selection and Material Sourcing

We act as agent for a number of leading Chinese steel and aluminum mills. That only helps you if the right one is chosen for the part in front of us, which is why sourcing starts with your drawing and your process rather than with a stock list.

Technical review of mill documentation against a part drawing

How This Works Stage by Stage

Each stage is a place where coil orders normally go wrong, and what we do differently there.

Stage 01

Requirement Review

The problemAn enquiry arrives as a grade and a tonnage, which hides the forming, the finish and the service environment that actually govern the choice.

How we handle itWe ask what the part does, how it is formed and where it lives before we discuss grade, so the specification is built from the part backwards.

Stage 02

Grade and Temper Selection

The problemGrade is often carried over from an old drawing and the temper is left unstated, which is where inconsistent springback comes from.

How we handle itWe fix grade, temper and surface together as one specification, and where a lower cost family will do the job we say so.

Stage 03

Mill Matching

The problemMills differ in rolling practice, gauge capability and how tightly they hold width and flatness at the thin end.

How we handle itWe place the order with the mill whose practice suits that gauge and that grade, rather than with whoever quoted first.

Stage 04

Order Placement and Follow Up

The problemOnce an order goes to a mill, most buyers lose visibility until it ships.

How we handle itWe hold the relationship with the mill and stay the single point of contact through production, so questions get answered in one place.


Mill Selection and Material Sourcing Questions

Are you a mill or a trader?
We are a technology trading company acting as agent for a number of leading Chinese steel and aluminum mills. Our value is in matching your specification to the right mill, not in owning a rolling line.
What do you need from me to start?
The part, how it is formed and where it will be used. Grade and tonnage alone are enough to quote but not enough to specify well.
Can you supply a grade that is not on your product pages?
Often yes. Around half our sales are customized rather than standard, so an unusual requirement is normally a specification discussion rather than a refusal.
