Commercial Stainless Steel Exhaust Hoods for Restaurant Kitchens

t466-23

A commercial stainless steel exhaust hood for a restaurant is a custom-built canopy that captures heat, smoke, and grease above cooking equipment and directs them into the extraction system. Stainless steel is the usual choice because it resists heat, corrosion, and grease buildup and is easy to clean every day. The hood should be sized and shaped to the actual cooking line and reviewed with the ventilation engineer before fabrication.

Why Stainless Steel Suits Commercial Kitchens

A restaurant kitchen puts a hood under constant stress: high temperatures, steam, cooking oil, and daily washing. Stainless steel handles all of these well. It does not rust under normal kitchen conditions, it tolerates repeated cleaning with kitchen detergents, and its smooth surface makes grease removal faster.

Choosing the right grade and finish matters. In practice, the surface should be smooth, with welds ground and polished so grease has nowhere to hide. Health inspectors look closely at hygiene, so a clean, well-finished hood also supports your daily compliance.

Sizing the Hood to Your Cooking Line

The hood must cover the full footprint of the cooking equipment, including ranges, fryers, grills, and ovens that produce grease or heat. A hood that is too small lets smoke escape into the room, while one that is poorly positioned loses capture efficiency.

Measure the full length and depth of each cooking appliance.
Note the mounting height and any obstacles such as shelves or lights.
Record the location of ducts, fans, and the exhaust route to the roof.

Accurate measurements taken on site are the basis for a drawing that fits the space exactly.

Design Features That Make a Difference

Good commercial hoods share several design features. Grease filters should be removable so they can be washed without tools. Edges should be folded or sealed to direct vapors upward, and the interior should slope slightly so condensed grease drains toward a collection point rather than dripping onto food.

Consider lighting fixtures built into the hood, access panels for duct cleaning, and a clean, uniform finish inside and out. Each detail adds to daily usability and long-term reliability.

The Ordering and Fabrication Process

Ordering a custom hood usually follows a clear path. It starts with an inquiry that includes photos and the kitchen layout. We then measure on site and prepare a drawing and written specification for your approval, so you know exactly what will be built before production begins.

Once approved, the hood is fabricated in our factory on Rival Street in Tel Aviv, finished, and installed. Confirm with your mechanical or ventilation engineer that the hood dimensions and connection points match the extraction design.

Coordinating with Ventilation and Fire Safety

A hood is one part of a larger system. The extraction fan, ductwork, make-up air, and fire suppression must work together. Your ventilation engineer should review the hood drawing early, especially the duct connection size and the required clearances from combustible materials.

Exact technical values depend on the equipment and the local requirements, so they should be confirmed with the engineer and the relevant authorities rather than assumed from general guidance.

Maintenance That Keeps the Hood Working

A stainless steel hood is easy to maintain, but it still needs a routine. Remove and wash grease filters regularly, wipe the interior and exterior surfaces daily with a suitable food-safe cleaner, and schedule professional duct cleaning as your operation requires.

Daily: wipe surfaces and check the grease collection tray.
Weekly: wash filters and inspect seals and edges.
Periodically: arrange professional duct and fan cleaning.

Frequently asked questions

What stainless steel grade is used for restaurant exhaust hoods?

A grade suited to kitchen conditions is typically used, chosen for heat and corrosion resistance. The exact grade should be confirmed during the specification stage based on your kitchen.

Do I need a drawing before the hood is built?

Yes. A drawing and written specification are prepared after on-site measurement and approved by you before production starts, so the hood fits your space and equipment.

Can a custom hood fit an unusual kitchen layout?

Yes, custom fabrication is designed for this. The hood can be shaped and sized to the exact cooking line, wall positions, and ceiling height of your kitchen.

Who should check the hood before installation?

Your ventilation or mechanical engineer should review the dimensions, duct connection, and clearances. This ensures the hood works correctly with the extraction system and meets requirements.

Common mistakes to avoid

The most common error is ordering a hood from rough measurements without confirming the exact cooking line and duct location. Skipping the engineer review before fabrication can lead to costly corrections on site.

Our recommendation

Before ordering, map every cooking appliance with its dimensions and the planned duct route, then have your ventilation engineer approve the drawing. This single step prevents most fit and performance problems.

Summary

A custom stainless steel exhaust hood, sized to your cooking line and reviewed with your engineer, gives a restaurant kitchen reliable capture, easy cleaning, and long service life.
