Notes for stainless and non-ferrous buyers
Short, practical notes on specifying stainless finishes, aluminium grades and copper coil for electrical and architectural work.
Stainless Surface Finishes: 2B, BA, 8K and HL Explained
The finish is a specification, not a preference. It changes corrosion behaviour and how the surface survives handling.
Copper Coil: C1100 and T2, and Why Temper Matters
Two grades with very similar conductivity behave differently on the line. Temper, not grade, is often the real deciding factor.
Ordering Aluminium Billet and Rod: Alloy, Diameter, Length
Aluminium is bought by alloy and by cut length. Getting the alloy wrong shows up later, in strength or in finish.
