Where this product is used

Key specifications

Selecting the right option

Stainless key steel suits corrosive, wet, and food-grade environments — not a direct cost-competitive substitute for zinc-coated mild steel in standard applications. Select square or rectangular section to match the keyway specification. Key steel is supplied in standard lengths — cut to the required key length on site.
