The IGT (Iron Grill Table) modular camping system has transformed how outdoor enthusiasts approach camp kitchens. But when it comes to choosing a frame, one decision stands above all others: aluminum or steel?

Both materials have passionate advocates, and both have distinct advantages. This guide breaks down the weight, durability, and cost differences so you can make an informed choice for your next IGT purchase.

Why Frame Material Matters

The frame is the backbone of any IGT setup. It determines how much weight your table can hold, how easy it is to transport, how long it will last outdoors, and ultimately how much you'll pay. A traditional camping table with thin aluminum sheets and crossed legs might be lightweight, but it often suffers from resonance—chopping on it makes the whole table dance. A quality IGT frame, whether steel or aluminum, uses thickened materials with precision locking mechanisms that eliminate wobble.

The global camping furniture market was valued at USD 8.78 billion in 2025 and is projected to reach USD 9.54 billion in 2026. Within this growing market, IGT tables have become especially popular in Japan, Europe, and North America. Understanding frame materials is now essential for both individual campers and B2B buyers.

Aluminum IGT Frames: The Lightweight Champion

Weight and Portability

Aluminum's greatest advantage is its low density—roughly 2.7 g/cm³ compared to steel's 7.85 g/cm³. This translates directly into real-world weight savings.

Real-world numbers:

• Snow Peak's 3-unit IGT frame weighs 4.2 kg

• Their 4-unit collapsible frame comes in at 4.1 kg

• Naturehike's 3-unit aluminum table weighs just 3.65 kg but supports up to 120 kg

• Blackdog's aluminum IGT table weighs 3.29 kg with a 120 kg capacity

Even the legs themselves show the difference. A set of stainless steel IGT legs weighs about 0.76 kg (1.7 lb), while 7075 aluminum legs weigh just 0.36 kg (0.79 lb)—half the weight.

For campers carrying gear by hand, even a 1-2 kg difference matters. That's why many outdoor brands now prefer aluminum-frame camping furniture for the current market.

Corrosion Resistance

Aluminum is naturally corrosion-resistant. When exposed to air, it forms a protective oxide layer that prevents further degradation. Even if the coating gets scratched, aluminum won't rust. For coastal camping or humid environments, this is a game-changer.

Premium manufacturers often take it further. Some use anodized 6063 aluminum alloy for enhanced corrosion resistance. Others use A6061 aluminum—machined side rails from A6061 give the frame a solid, rigid structure. The 6061-T6 alloy offers a yield strength of about 240 MPa, making it strong enough for most camping applications.

Drawbacks

Aluminum isn't indestructible. It's more prone to denting than steel under heavy impact. Cheap cast aluminum corners can snap without warning. And while aluminum frames are strong, they need to be thicker than steel to provide equivalent stiffness—though this is rarely a practical concern for typical camping use.

Steel IGT Frames: The Heavy-Duty Workhorse

Strength and Stability

Steel offers superior structural rigidity. The Q235 carbon steel commonly used in camping tables has a yield strength of about 235 MPa—similar to 6061 aluminum on paper. But steel's higher density (7.85 g/cm³ vs aluminum's 2.7 g/cm³) means that at the same wall thickness, steel's bending stiffness is roughly 2.3 times higher.

This translates to real-world performance. Steel IGT frames feel rock-solid on uneven ground. On soft ground, steel leg frames can provide about 40% more support than comparable aluminum tables.

Some premium IGT systems blend materials. Snow Peak's frames, for example, combine steel and aluminum for optimal durability—the steel adds strength at critical stress points while aluminum keeps overall weight manageable.

Durability Considerations

Steel is highly durable when properly protected. Quality steel frames with powder coating and proper pre-treatment can last for years.

However, steel has one major weakness: rust. Untreated steel is highly susceptible to corrosion. Even with powder coating, weld splatter creates microscopic peaks and valleys where the coating thins. Under mechanical flexing during folding or transport, these thin spots crack first. Moisture wicks in, and if the factory skipped phosphating pre-treatment, red rust starts within weeks.

The key is proper specification. Steel frames should undergo zinc or iron phosphating before powder coating. A 72-hour salt spray test can verify the coating's effectiveness.

Weight Penalty

Steel is significantly heavier. A typical steel camping table frame can weigh 6-8 kg, compared to 3-5 kg for aluminum. For car campers who don't carry gear far, this may not matter. But for anyone who hikes to camp or values easy transport, the weight difference is substantial.

Cost Comparison: The Numbers That Matter

Upfront Price

Steel is cheaper—often considerably so. A 2-3 unit entry-level IGT aluminum frame can cost around 200-300 RMB ($28-42)**. A mainstream 5-unit "master table" aluminum IGT typically runs **550-600 RMB ($77-84). At the premium end, Snow Peak's Entry IGT with steel components weighs 6.5 kg—significantly heavier than their all-aluminum alternatives.

Steel frames are usually cheaper because steel is less expensive as a raw material and easier to manufacture. However, the price gap narrows when you factor in proper corrosion protection. A well-made steel frame with phosphating and powder coating costs more than bare steel.

Total Cost of Ownership

This is where the math gets interesting. An aluminum frame costs more upfront but requires virtually no maintenance—no rust, no repainting. A steel frame is cheaper initially but may need repainting if the coating gets damaged, and rust repair can be costly.

For coastal or humid environments, aluminum's corrosion resistance makes it the more economical long-term choice. For indoor or dry-climate use, steel's upfront savings may outweigh its maintenance needs.

Head-to-Head Comparison

Which Should You Choose?

Choose aluminum if:

• Portability matters—you carry gear by hand, hike to camp, or have limited storage

• You camp near saltwater—aluminum won't rust in coastal environments

• You want low maintenance—no repainting, no rust worries

• You're willing to pay a premium for weight savings and corrosion resistance

Choose steel if:

• Budget is your primary concern—steel frames are cheaper upfront

• Maximum stability is non-negotiable—steel offers superior rigidity on uneven ground

• You're car camping—weight isn't a major factor

• You camp in dry climates—rust risk is minimal

The Hybrid Solution

Many premium IGT frames now combine both materials. Snow Peak's frames, for instance, use aluminum alloy with stainless steel reinforcements at critical stress points. This gives you the best of both worlds: aluminum's lightweight portability with steel's strength where it matters most.

The 5.5U collapsible IGT frame, for example, features machined side rails from A6061 aluminum that are strong enough to support the weight of a grown adult (130 lbs recommended load limit).

The Bottom Line

Aluminum IGT frames win on weight and corrosion resistance; steel frames win on cost and raw rigidity. For most campers who value portability and outdoor durability, aluminum is the better long-term investment. For budget-conscious car campers who don't carry gear far, steel offers excellent value.

As one industry observer put it: "Aluminum material makes a big difference. Steel tables are usually cheaper, but they become heavier during transport and less convenient for outdoor travel. Aluminum alloy is now more common in mid-range and higher-end camping products because it keeps the table lightweight while maintaining outdoor durability".

Choose based on where you camp, how you travel, and what matters most to you. Both materials have earned their place in the IGT ecosystem—the right choice is the one that fits your adventure.
