A question?
Curious to know more about the ALTO barbecue?
Is the ALTO barbecue gas‑powered?
Yes, the ALTO gas barbecue is the COEO novelty of 2026.
What is the cooking surface of the ALTO?
The ALTO has a large cooking surface of 89 × 57 cm (35.04" × 22.44"), which is 5,073 cm².
How many heating zones are in the ALTO?
The ALTO offers six heating zones : 2 stainless steel plates, 2 stainless steel cooking grills, 2 burnerswith stainless steel gastronorm trays (GN) as well as an option for a motorised rotisserie.
How many burners are in the ALTO?
The ALTO is equipped with 3 extremely powerful ceramic burners: 1 searing burner with a power of 5kW and 2 high-performance burners of 3.5kW each. For a total power of 12kW.
Why are ceramic burners ultra-efficient?
Ceramic provides a strong and rapid heat, ideal for immediately searing food. It distributes heat evenly, for consistent and controlled cooking. It reduces flare-ups, as it acts as a barrier between the flame and the food. Radiant heat keeps food juicy without drying it out. Finally, ceramic is very durable and withstands high temperatures over time.
What material is the ALTO made of?
The entire ALTO barbecue is made of 304 stainless steel.
A gas barbecue has today become the most versatile and reliable solution for outdoor cooking. At COEO, we apply professional kitchen standards to high‑end barbecues: 304 stainless steel, French engineering, and an architectural design built to last.
The range is structured around ALTO, the flagship model that embodies our vision of a premium gas barbecue. On this page, you will discover the benefits of gas cooking, the key criteria to choose the right model, an in‑depth presentation of our iconic barbecue, and best practices for maintenance.
Why choose a gas barbecue?
The gas barbecueis the reference solution for ahigh-end outdoor kitchen, focused on ease of use, comfort and cooking precision. Unlike thetraditional charcoal barbecue, which requires time, preparation and management of the coals, the gas barbecue runs onpropane or butaneand offers animmediate ignition. Theheat is available in a few minutes, with aprecise temperature controlthanks to the control knobs and theindependent burners..
The traditional charcoal barbecue has a more random combustion, and in comparison, the gas barbecue ensures a uniform heat distribution over the entire cooking surface. It is perfectly suited for grilling, for the griddle, for using the hot plate or for the indirect cooking of meats and delicate foods, with a consistency that is difficult to achieve with charcoal.
Designed for family meals and entertaining, a premium barbecue offers a generous and modular cooking surface, sized to the number of guests. With interchangeable grates, modular culinary systems, integrated storage, and a refined design created for the garden or an outdoor kitchen, it combines functionality, versatility and elegance.
The absence of ashes, soot and charcoal‑related residues, combined with easy maintenance and the use of durable materials such as stainless steel, ensures superior ease of use, efficiency and longevity.
In a market offering a wide range of charcoal, wood and gas barbecues, choosing a high‑end gas barbecue means gaining in comfort, reliability and performance‑to‑price ratio, for clean, controlled and durable cooking with every use.
How to choose the right gas barbecue
Choosing a gas barbecue is based on objective technical criteria that determine performance, durability and ease of use.
Power and number of burners
The power output of a gas barbecue is a decisive factor when making the right choice. Expressed in kilowatts (kW), it directly affects heat‑up time, cooking quality and even heat distribution across the cooking surface.
A gas barbecue becomes truly effective from 9 kW, with at least three burners, making it suitable for regular meals for several guests. High‑end models in the premium range reach 12 kW or more, providing excellent cooking control, high precision and improved energy efficiency when using propane or butane gas, regardless of the gas bottle used.
Independent burners allow power to be adjusted according to the food being cooked: high‑heat searing, indirect cooking, plancha use, side burners or grilling on stainless steel grates.
Ceramic or infrared burner systems represent the latest market innovations, offering better air and heat distribution, faster heat‑up times, controlled gas consumption and greater durability than standard stainless steel burners. This level of performance improves long‑term value for money, reduces maintenance needs and builds confidence for everyday use, whether in an outdoor kitchen or garden setting.
Cooking surface area
When choosing a gas barbecue, the cooking surface area is a key criterion, just as important as power, burners and features.
A commonly accepted guideline is to allow around 250 cm² per guest, ensuring efficient cooking during meals. A family‑size gas barbecue typically offers a surface area between 2,000 and 2,500 cm², ideal for regular garden use.
Premium, high‑end models often exceed 4,000 to 5,000 cm², delivering more even heat distribution, precise temperature control and true culinary versatility.
A modular surface, combining grills, griddle and burner, transforms the barbecue into a trueoutdoor kitchen: grilling meats, simultaneous cooking of different foods, keeping warm and managing meals for multiple people. Combined with high-performanceburners, qualitymaterialssuch asstainless steel, this configuration enhances efficiency, cooking precision and thevalue for moneyin the long term. Compared to traditionalcharcoal, a gas barbecue stands out for its ease of use, the absence ofash, simplified maintenance and rapid temperature rise, providing comfort, confidence and performance with every use. It allows for simultaneous cooking of differentfoods, adjusting the power according to needs and fully utilising the features of a truepremium outdoor kitchencuisine extérieure premiumin the garden.
Materials: why 304 stainless steel makes all the difference
304 stainless steel is the reference material in professional kitchens and a decisive criterion when choosing a high‑end gas barbecue. It offers exceptional resistance to corrosion, high temperatures, air exposure and acidic foods, while ensuring consistent hygiene and quality with every use.
Thanks to 304 stainless steel, a premium gas barbecue can last 10 to 15 years, even with intensive use, compared to only 3 to 5 years for painted steel models. In a market rich in products and ranges, this material guarantees excellent long‑term value for money.
Conversely, it is recommended to avoid painted steel, thin cast aluminum or low‑grade thermoformed parts, which are more sensitive to heat, wear and the constraints of propane or butane gas cooking. These materials negatively affect heat distribution, actual burner performance, maintenance and overall durability.
A 304 stainless steel gas barbecue inspires confidence, simplifies maintenance, limits residue buildup and ensures consistent performance for grilling, plancha cooking, side burners and all outdoor kitchen uses, from garden cooking to the most demanding applications.

ALTO delivers complete culinary freedom, consistent cooking quality and durability designed for intensive use, whether at the heart of the garden or within the most demanding outdoor kitchens.
12 kW ceramic burners and 6 cooking zones
ALTO is equipped with three ceramic burners, delivering a total output of 12 kW:
– 1 searing burner – 5 kW
– 2 high‑performance burners – 3.5 kW each
The 5,073 cm² cooking surface (89 × 57 cm) is divided into six zones :
2 stainless steel planchas, 2 stainless steel grates, 2 side burners compatible with gastronorm containers.
Optional accessories include a motorised rotisserie and a pizza stone. Burner maintenance is simplified thanks to the ceramic burn‑off process, which removes residues through high‑temperature cleaning.
100% 304 stainless steel construction
A true high‑end stainless steel barbecue, the ALTO gas barbecue by COEO represents excellence in design and performance. Its entire structure — frame, planchas, grates, side burners and insulated lid — is made from professional‑grade 304 stainless steel.
A benchmark material in premium kitchens, this stainless steel guarantees outstanding resistance to corrosion, high temperatures and intensive outdoor use.
The insulated lid of the ALTO barbecue optimises heat retention, ensures even cooking and improves energy efficiency, enabling precise performance control. Faithful to the COEO DNA, ALTO is built to last, maintaining its thermal, mechanical and aesthetic qualities year after year..
Deux versions : SOLO ou UNIT
ALTO is available in two configurations:
UNIT: with integrated cabinet, featuring doors, storage space, a dedicated gas bottle compartment and castors for complete autonomy.
SOLO: without cabinet, designed to be placed on a worktop or built into a custom outdoor kitchen.
Both versions offer exactly the same technical performance. Full specifications are available at the bottom of the page, and our customer service team can assist you in choosing the right configuration.
How to maintain your gas barbecue
Maintenance of the ALTO COEO gas barbecue has been designed to be simple, fast and effortless. After each use, it is recommended to let the barbecue run empty for about 5 minutes, allowing food residues to burn off naturally. Brushing the grates while still warm is then sufficient to restore a clean surface.
Thanks to the side‑mounted burners, grease does not drip directly onto the burners: it flows into an easy‑access grease collection tray, which is quick and simple to clean. The burners, protected from grease, require no complex cleaning.
The grease drawer can be easily emptied and cleaned, making maintenance even simpler.
Between uses, covering the barbecue with a protective cover is recommended to shield it from the elements and extend its lifespan. An annual check of the hose and regulator ensures safety and reliability.
When properly maintained, the barbecue retains performance, cleanliness and durability for 10 to 15 years.
FAQ
A good gas barbecue should be chosen for its build quality, ideally made from stainless steel, with powerful, independent burners for precise temperature control and even heat distribution. Choose a model that is easy to maintain, features grease collection, suits your cooking needs and is designed to last outdoors.
The right power level mainly depends on the cooking surface area. As a general rule, allow 3 to 4 kW per burner, which corresponds to 10 to 14 kW for a family‑size gas barbecue. The key factor is not maximum power, but even heat distribution and independent burners, which ensure precise and controlled cooking.
A gas barbecue stands out for its quick ignition, precise temperature control and easy maintenance, with no ashes or ember management. A charcoal barbecue, on the other hand, appeals with the authentic smoky flavour it delivers, but requires more time, handling and a less consistent control of cooking. The choice therefore depends on your priorities: comfort and precision, or tradition and smoky flavour.
