Stainless Steel Surface Finish Reference
2B
Cold rolled, annealed and pickled with a final light skin pass. Smooth, slightly reflective. Most common sheet finish. Suitable for most fabrication, food processing and general use.
BA (Bright Annealed)
Annealed in a controlled atmosphere to produce a bright, mirror-like finish. Used for decorative, architectural and catering applications requiring high reflectivity.
No.4 (Brushed / Satin)
Mechanically polished with 150–180 grit abrasive to produce a unidirectional brushed finish. Standard for architectural cladding, lift panels, benchtops and handrails.
2D (Hot Rolled, Annealed & Pickled)
Hot rolled, annealed and pickled. Dull, matte grey finish. Used for plate and heavy gauge sheet where surface appearance is not critical. Standard for pressure vessel plate.

Copper Material Reference — KME CU-DHP
Designation: CU-DHP (Cu-DHP)
Oxygen-free, phosphorus-deoxidised copper. Minimum 99.90% Cu. Residual phosphorus 0.015–0.040% provides excellent weldability and solderability.
Standard: EN 1172
European Standard for copper and copper alloy sheet and strip for building purposes. Covers dimensions, tolerances, mechanical properties and surface condition.
Temper / Condition: R220 (Soft)
Annealed condition (R220 = min tensile 220 MPa). Soft temper provides maximum formability for complex shapes, gutters, sumps and roofing profiles.
Thickness Range: 0.55–3.00 mm
Stocked from 0.55mm (flashings, trim) through to 3.00mm (structural decorative elements). Most common roofing gauges: 0.70mm and 0.90mm.
Surface / Patina: Mill Finish → Green Patina
Supplied with a matt dark brown mill finish. Naturally oxidises over time — first to a dark brown/black, then to the characteristic green patina (verdigris), which provides long-term corrosion protection.
Fabrication: TIG Weld · Solder · Fold · Roll
CU-DHP is fully TIG weldable and solderable. Excellent formability regardless of temperature and rolling direction. Suitable for brake press folding, roll-forming and complex fabrication.
