Coil Supply for Automotive Components
Automotive component work is a weight argument conducted in tenths of a millimetre. Every part is under pressure to lose thickness without losing load capacity, and every grade change has to survive both the press shop and the welding line.
Where It Goes Wrong
- A bracket is thicker than it needs to be because only mild steel was available in the width
- Moving to a higher strength grade changes springback and the tool no longer produces to print
- Corrosion requirements force a coating step after forming
- Hot dry components are specified in austenitic stainless and carry unused corrosion resistance
What the Sector Actually Needs
- High strength low alloy strip for load bearing stamped parts
- Deep drawing quality for formed housings and shells
- Galvanized substrate where parts sit in a wet or splash zone
- Ferritic stainless for hot dry components

How We Deliver Into This Sector
- Grade selected against a calculated load rather than rounded up to the next stocked item
- Slit width to the strip your progressive die runs
- Consistent gauge across the width so the die bottoms evenly

Uncoated cold rolled strip is cheaper per tonne, but the comparison only makes sense once the cost of coating the finished part is included. This guide sets out where each one belongs.
