  • Cooking Space: 580 sq. in.
  • Heat Control: 4 burners (48,000 BTU)
  • Dimensions: 66″W x 27″L x 50″H
Check On Amazon Check On Weber

Weber Summit S-470 Gas Grill is a distinguished product in the high-end grill market. From a brand well-respected in the grill industry, Weber, the Summit S-470 is no ordinary gas grill.

With 304 and 430 stainless-steel components and an impressive range of features, it stands up quite well, even against other top competitors.

Burners and Cooking Area

Boasting a front-mounted lighted control panel with four stainless-steel burners, it employs a Snap-Jet individual burner ignition system, making it user-friendly.

Other Features

The grill’s convenience features significantly enhance the user experience. For instance, the enclosed cart, two stainless-steel side shelves, and six tool hooks add to the practicality of the design.

For those who enjoy night grilling, you’ll appreciate the Grill Out Handle light and lighted control knobs.

The Grill Out Handle light is activated when the lid opens, providing enough illumination for nighttime cooking. (I quite like this feature)

Alternatively, you can opt for a manual check by observing the color indicator line on the tank scale’s side.



However, it’s not without its downsides. The Weber Summit S-470 is undoubtedly a significant investment, with its “high-end” price tag.

This is achieved through a unique emitter plate that collects the juices from the meat, evaporates them, and redirects them back onto the food. This process enhances the flavor and ensures the food retains its moisture.

In addition, the grill’s porcelain-coated grates add an extra layer of convenience. These grates are not only durable and rust-resistant, but also straightforward to clean.

To add a smoky flavor to your food, you can even place wood chips directly onto the grill grates.


The grill offers 24,000 BTUs spread across three top-ported stainless steel burners and a side burner that delivers 10,000 BTUs, perfect for preparing sauces or sides.

Although its BTU rating is lower than some competitors, the burners are durable for longer-lasting performance and provide a wide temperature range with precise control.

Cooking Area

The Char-Broil 463370719 offers a sizable cooking area of 600 square inches, of which 450 square inches are designated for primary cooking, and an additional 150 square inches serve as a warming rack.

Diving into the features of the Monument Grills Mesa 200, it’s clear that it’s a compact version of the Mesa 400 with some distinctive characteristics.

This cheap rust-proof grill has carved out a niche in the market, especially appealing to those residing in coastal regions such as Florida.

Burners and Grill Grates

The Mesa 200 harnesses the power of two primary 304 stainless steel burners, each emitting 24,000 BTUs of heat, for a strong and consistent cooking performance.

Its grilling area stretches over 473 square inches, including 326 square inches for the primary cooking space and an extra 147 square inches for the warming rack.

This ample space allows for diverse cooking options, such as 15 burgers, a rack of ribs, two whole chickens, or a dozen chicken thighs, catering well to small families or gatherings of 4 to 6 people.

Designed for even heat distribution, the porcelain-coated, cast-iron cooking grates work alongside enamel flame tamers to enhance the flavors of your grilled foods.


Additional Features

The built-in Clear View Lid is a notable inclusion, enabling you to monitor your grilling progress without losing valuable heat, thereby maintaining consistent cooking temperatures.

Unlike the Mesa 400, the Mesa 200 offers foldable side shelves, each 13 inches wide, providing ample workspace when extended and saving space when not in use.

However, it’s important to note that the Mesa 200 does not include a side burner for searing due to these folding shelves.

The Mesa 200 also stands out with several stainless steel elements, including a 430 stainless steel lid, door, and side shelves. However, while the back and base panels are highlighted with a silver powder coating, their rust resistance is somewhat lacking.

Guide to Choosing Beach House Grills

Choosing a gas grill, especially for coastal environments, can be a bit daunting with the variety of options available. Here’s a guide to help you decide and choose the perfect grill for your needs.

1. Understanding Rust-Resistance in Grills

One of the key factors to consider while choosing a gas grill for the beach house is rust resistance. Salt air and humidity can make a grill susceptible to rust, hence the importance of materials and maintenance.

Stainless steel, known for its durability, ease of cleaning, and rust resistance, is a popular choice for grill construction. But be mindful that not all stainless steel is the same – the grades matter, especially when considering a grill that doesn’t rust.

304, 430, and 443 are different grades of stainless steel commonly used in grills, each with their unique characteristics and rust-resistance capacities.

Grade 304 stainless steel is often considered commercial grade, characterized by its non-magnetic property and superior corrosion resistance. Its high chromium and nickel content make it highly rust-resistant, ensuring longevity even in coastal environments.

Owing to these attributes, grade 304 is typically found in high-end grills or specific parts of grills made of other steel grades. The downside is that it tends to be more expensive and harder to find.

Grade 430 stainless steel is usually found in more affordable, low-priced grills. This grade is magnetic due to its higher iron content, which, unfortunately, makes it more prone to rust and stress fractures.

Grills made from grade 430 stainless steel often require frequent polishing to maintain their appearance.

Grade 443 stainless steel is a recent addition to the grill construction scene. Containing more chrome and titanium, this grade is also magnetic but stands out due to its impressive durability and rust resistance, which nearly matches that of grade 304.

Another advantage is that it’s generally more affordable than grade 304, making it an increasingly common choice for affordable grills like the Char-Broil 463370719.

It’s essential to note that even if the main body of a grill is made of high-quality stainless steel, other parts like grates or burners might be made of different materials, such as cast iron or porcelain-coated steel.

These materials can rust if not adequately maintained, so checking all parts of your grill for quality before purchase is crucial.

A quick note about the “magnet test”: a magnet was once believed to determine a stainless steel’s grade. If the magnet stuck, it was assumed to be grade 430; if not, grade 304.

But this test has become unreliable with the introduction of the magnetic 443 grade. So, to reassure customers about quality, manufacturers often clearly state if a grill is made from the rust-resistant grades 304 or 443.

Contact the manufacturer for accurate information about the grill you are aiming for.

2. Burners

The quality and number of burners directly influence the grill’s heat distribution and temperature control. A grill with at least two to three burners can create different heat zones for versatile cooking (direct and indirect cooking).

Additionally, the BTU (British Thermal Units) rating should be considered, which indicates the heat output. However, higher BTUs don’t always mean better performance; around 80-100 BTU per square inch of cooking area is generally adequate.

3. Grates

Grill grates can be made of various materials like cast iron, porcelain-coated steel, or stainless steel. While cast iron grates are durable and retain heat well, they require regular seasoning to prevent rusting.

Porcelain-coated steel grates are easy to clean and resist rust but can chip or crack over time.

Stainless steel grates are long-lasting and rust-resistant, though they might be a bit expensive and hard to clean.

Besides the grate’s material, you should consider both the material of the warming rack and the side burners.

4. Size and Cooking Area

Your grill’s size should cater to your cooking needs and the space you have available. For instance, if you often cook for large groups, larger models like the Napoleon Prestige 500 and Mesa 400 could be ideal.

On the other hand, if you primarily grill for a small family and have limited space, compact models such as the Char-Broil 463370719 and Mesa 200 should suffice.

5. Personal Preference and Style

Ensure that your grill aligns with your personal cooking style. If you’re someone who enjoys a diverse cooking range – from pancakes and eggs to searing a steak – consider grill and griddle combos.

Moreover, if you’re a fan of smoked flavors, grill-smoker combo models may be a perfect fit. Models like the Weber Summit S-470 come with a built-in smoker box and burner. Alternatively, you can customize any gas grill with a separate smoker box.

6. Additional Features

Don’t overlook features that can enrich your grilling experience. Side burners, for instance, can help prepare side dishes or sauces.

Some grills come equipped with a rotisserie attachment or a smoker box, adding versatility.

Features like LED lights in the grill lid or on the control knobs can facilitate night grilling.

Also, certain high-end grills offer smart features, including apps that allow you to control the temperature remotely.

7. Budget

The cost of grills can vary widely, so finding a balance between price and quality is essential. This ensures that your grill does not rust prematurely and remains functional over the years.

If you’re beginning to explore grilling and are on a tight budget, consider affordable models like the Mesa 200, Char-Broil 463370719, or even the Mesa 400.

However, if you have room in your budget, don’t hesitate to invest in premium models like the Napoleon Prestige 500 or the Weber Summit S-470.

It’s about making a smart investment that caters to your grilling needs while ensuring durability.

Tips to Rust Proof a Grill

Tips to Rust Proof a Grill

Rust proofing your grill, especially in environments with salt air, is crucial to keep it in peak condition. The stainless steel used in grills can oxidize in the presence of chlorides and sulfides, abundant in coastal areas or near hot tubs and pools.

Here are a few practical ways to maintain your gas grill and guard against rust.

1. Regular Washing to Prevent Oxidization

Start by washing the grill’s surfaces regularly. Aim to do this every 3-4 weeks. Use warm, soapy water and a gentle cloth to remove any dirt or grime.

However, bear in mind that your grill needs to be cool before you begin, for safety reasons and to prevent surface corrosion from occurring due to extreme heat.

2. Maintaining the Aesthetic Appeal

Maintaining the grill’s aesthetic appeal requires more care. Post-use, wash it using a mild detergent and warm soapy water, then dry with a soft cloth.

Grease deposits might necessitate the use of an abrasive plastic pad. Apply this only in the direction of the brushed finish to avoid damage, steering clear from areas with graphics.

3. Grill Cleaning: Materials and Techniques

Cleaning your grill doesn’t have to be a struggle. Arm yourself with a soft cloth or microfiber cloth and a mild detergent. Stay away from steel wool, abrasive cleaners, or paper towels that might scratch the surface.

Always rinse with clean water and dry with a fresh cloth to prevent water stains. Remember to follow the grain of the stainless steel during cleaning to prevent unwanted scratches.

4. Polishing: Preserving the Shine

Next, consider polishing your grill. A stainless steel polish not only helps it keep its shine but also protects against stains and rust.

Alternatively, a light coat of vegetable oil or cooking spray can act as a protective barrier against moisture and salt.

5. Covering and Storage: Guarding against Elements

Remember to cover your grill when it’s not in use. A breathable and water-resistant cover is ideal as it curtails condensation and mold growth.

Lastly, store your grill in a dry, sheltered place during harsh weather conditions or the off-season. This simple action can help prevent rust and corrosion caused by exposure to elements such as rain, snow, or salt spray.

By employing these methods, you can preserve the longevity and functionality of your gas grill, ensuring many more seasons of delightful barbecues.


That’s a wrap, grillmasters! Remember that critical elements like the type of stainless steel, size, personal cooking style, extra features, and budget are vital when choosing the best rust-resistant grills for coastal environments.

The salty air in coastal regions like Florida is notorious for being tough on grills. But armed with this guide, you’re ready to make a savvy choice.

So, here’s to many sun-soaked cookouts by the coast – with the right grill, rust won’t dampen your barbecue fun. Happy grilling, friends!
