Coil Supply for Appliance Manufacturing

Appliance work puts two contradictory demands on one coil: the visible face has to be flawless and the hidden structure has to be cheap. Getting both usually means specifying different material for different parts of the same product, which is only practical if one supplier covers the whole range.

Where It Goes Wrong

  • A drum or liner splits on the final draw and the grade cannot be changed without requalifying a supplier
  • Visible fascia panels show rolling marks because 2B was supplied where BA was needed
  • Hidden brackets carry stainless cost they do not need
  • Trim colour drifts between production batches of painted aluminum

What the Sector Actually Needs

  • Deep drawing quality for drums, liners and shells
  • A bright finish on anything the customer sees
  • Economical protected steel for structure and hidden parts
  • Consistent finished aluminum for trim

Typical Applications

  • Washing machine drums drawn from 300 series stainless
  • Oven and cooker panels in 400 series where service is hot and dry
  • Cabinet structure in DC01 or galvanized DX51D
  • Fascia and trim in painted or anodized aluminum

How We Deliver Into This Sector

  • One specification conversation covering every material in the product
  • Slit widths set per part so narrow brackets stop being blanked from wide coil
  • Finish specified per visible face rather than per order

Appliance Manufacturing Questions

Which stainless grade suits a washing machine drum?
Drums are normally drawn from 300 series, because the combination of deep draw and wet service is exactly what austenitic stainless is good at.
Can I use 400 series for oven panels?
It is a common choice. Service there is hot and dry, which is where ferritic grades resist oxidation well and expand less than austenitic ones.
How do I stop trim colour varying between batches?
Order painted aluminum for matching areas from a single coil run and tell us which parts have to match, so the slit plan keeps them together.
