Zinc Alloy or Stainless Steel Lever Handle: How to Choose

Updated 2026-11-05 · RAYEN 雷茵

Most of the 240 models in our lever handles are zinc alloy or stainless steel, with aluminium as a third choice. The decision looks like a price question. In practice it comes down to four things you can check: the finish, the shape, the door range and the lock case.

What is the difference between zinc alloy and stainless steel levers?

• Zinc alloy is cast in a mould. The shape can be nearly anything the mould can release, and the colour is a coating on the casting.
• Stainless steel on our tube levers is formed from tube, and the surface you see is the metal itself. S-01 is one of these hollow tube levers.
• Some stainless levers are cast too: UL680 and UL780 are investment-cast stainless steel.

You can see that in the photos. A5-653 in zinc alloy has a thin, sharp blade. S-01 in stainless steel is a plain curved tube. SF-15 is a broad, curved stainless lever on a square rose. Neither material is the better one. They do different jobs.

Which finishes come in zinc alloy and stainless steel?

Zinc alloy has the long list. Across our models you will find matt black, brushed black nickel, brushed satin nickel, brushed light gold, antique yellow brass, zirconium gold and antique bronze, plus white, red and grey. A5-965 and KA9-9933 are among those offered in colours.

Zinc alloy also takes covered grips. KA9-9929 and KA5-9922 come with a leather wrap, while A5-343 and KA5-9911 carry wood grain.

Stainless steel has a short list on purpose. Our 304 / 316 levers come in brushed stainless, mirror polished stainless and zirconium gold. S-K210 adds rose gold. The 304 stainless plates such as SY5801-100 are listed in brushed stainless.

If the project needs a colour, zinc alloy is the short answer. If it needs brushed metal that stays brushed metal, take stainless steel.

Which is better for a bathroom or a coastal door?

Take stainless steel there. On zinc alloy, everything depends on the coating, so a scratch or worn edge in wet or salty air becomes the weak point. On stainless steel the metal is the surface. Our S, SA and SF levers are listed in 304 or 316: tell us which one on the order, and ask for 316 if the door is by the sea or a pool. If the door is indoors in a dry room, zinc alloy is a sound choice and gives you far more finishes.

How do door thickness and lock case differ?

This part is easy to miss, and it can decide the matter.

• Zinc alloy rose levers: door 38-50mm, lock case 8550 / 7255.
• Stainless steel 304 / 316 levers: door 32-50mm, lock case 7255 / 7855.
• 304 stainless plates: lock case 5845, with door 35-50mm on SY5801-109 and SY5802-101.
• Zinc alloy plates: lock case 5845, door 38-50mm, as on 58150-704.

So on a 32mm door the stainless levers stay and the zinc alloy levers drop out. If a project has already bought a 7255 case, both work. If it has bought 8550, you are on the zinc alloy list. Our guides to door thickness and lock case numbers go through each code.

How heavy are stainless steel levers?

Here are the stainless levers with a stated weight.

UL745 is 0.38kg and UL1005 is 0.82kg, more than double, on the same Ø50mm rose. If weight is part of how you sell the handle, ask for a zinc alloy and a stainless sample and put them on a scale.

Where does aluminium fit?

Aluminium is the third choice. Our AL levers, such as AL-114, come in anodised matt black, sand white and sand gold, with lock case 5845 / 7250 and door 35-50mm where a range is given. Anodising is a different kind of surface from plating, and the colour range is narrower.

What should you check before choosing?

• Where the door is: indoor, wet room, coast or exterior.
• The finish everything else on the door has to match.
• The door thickness, measured on the finished door.
• The lock case, if it has already been chosen.
• A sample in the hand. Weight and edge feel are hard to judge from a page.

What to write on your order

State the material and the grade on the line, not just the model: model, material, finish, lock case, door thickness and quantity. For example: S-01, stainless steel 316, brushed stainless, lock case 7255, door 32-50mm. Or A5-653, zinc alloy, matt black, lock case 7255, door 38-50mm. Not sure which suits the door? Send us its position and a photo, and we will suggest two to compare.
