To select the right Chinese wok for a commercial kitchen, match four things to how you cook: the wok type (round-bottom for traditional high-heat stir-frying, flat-bottom for standard cooktops), the material (carbon steel is the professional default), the size (14 to 32 inches, scaled to your volume), and a burner powerful enough to drive it. Get those four right and you cook faster, develop genuine wok hei flavour and hold consistent results through a busy service. This guide walks through each choice, with a comparison of wok styles and answers to the questions chefs ask most.

Types of Chinese wok for commercial kitchens
Knowing the differences between wok styles helps you pick one that suits your cooking methods and workflow.
Round-bottom woks
The traditional choice in Chinese kitchens. The curved base concentrates heat at the centre and gives you room to toss, which is what authentic stir-frying needs.
- Excellent heat distribution
- Ideal for fast stir-frying and tossing
- Creates authentic wok hei flavour
- Best paired with a dedicated Chinese wok burner
Flat-bottom woks
Designed for stability on flat cooktops, so they suit kitchens that do not have a traditional wok range.
- Works on standard commercial stovetops
- Suits kitchens without dedicated wok ranges
- Less effective at producing true wok hei
Mandarin vs Cantonese woks
| Type | Handles | Best use | Advantages |
|---|---|---|---|
| Mandarin wok | One long handle | High tossing techniques | Great control and manoeuvrability |
| Cantonese wok | Two small handles | Heavy cooking and large batches | Stability when lifting and serving |
Best materials for professional woks
The material affects how the wok heats, how long it lasts and how flavour develops.
Carbon steel (most recommended)
- Lightweight and durable
- Heats up rapidly
- Develops natural seasoning over time
- Preferred by most professional chefs
Cast iron
- Excellent heat retention
- Suits slower, flavour-intensive cooking
- Heavy and needs more care
Stainless steel
- Easy to clean and modern in appearance
- Less responsive to high heat
- Not ideal for traditional Chinese techniques
🔧 Pro tip, season before first service
A new carbon steel wok needs seasoning before you cook in it. Build up that layer properly and the wok becomes naturally non-stick, develops better flavour and resists rust through years of daily use.
Pairing the wok with the right burner or wok range
A wok only performs as well as the heat under it. Without a burner built for the job, even a great wok will fall short, especially when you are chasing wok hei.
Look for these features in a wok burner or range:
- High BTU output: Crucial for generating wok hei.
- Air-blast burners: Deliver intense, focused heat.
- Water-cooled tops: Improve safety and durability.
- Splashback and spill guard protection: Keep the station safe and clean.
It is worth speccing the wok and burner together. Browse our commercial wok burners and the wider Asian cooking range so the wok and heat source are matched from the start.
Choosing the right wok size
Commercial woks range from 14 to 32 inches. Choose based on cooking volume and the space you have.
| Kitchen size | Ideal wok size | Notes |
|---|---|---|
| Small restaurants | 14″ to 18″ | Good for low to medium volume |
| Medium kitchens | 20″ to 24″ | Suits most daily operations |
| Large restaurants | 28″ to 32″ | Handles large batches efficiently |
Also factor in how many chefs work the station at once and how many stir-fried dishes you push during peak service.
ℹ️ Bigger is not always better
An oversized wok on an underpowered burner heats unevenly and slows the line. Size the wok to the heat available and to one chef's comfortable tossing reach, rather than buying the largest option by default.
Maintenance for long-lasting woks
Good care extends a wok's life and protects the flavour it builds up.
- Season the wok before first use.
- Avoid harsh detergents on carbon steel.
- Dry immediately after washing to prevent rust.
- Store in a dry location.
- Inspect burners regularly for safety and performance.

Frequently Asked Questions
Carbon steel is widely preferred for its durability, fast heating and ability to develop natural seasoning over time, which is why most professional chefs choose it.
Yes. Larger woks handle higher volumes, while smaller woks give better control for low-volume kitchens. Match the size to your service volume and the heat output of your burner.
For authentic wok hei, a high-BTU wok burner is recommended. Standard stovetops will not generate enough heat to sear and toss food the way traditional stir-frying requires.
Round-bottom woks are ideal for traditional high-heat cooking on a wok range, while flat-bottom woks suit kitchens that rely on standard flat cooktops.
Stainless steel woks are easy to clean but less responsive to high heat, so they are not ideal for the high-temperature techniques central to Chinese cooking.
