3004 & 3105 Insulation Aluminum coil

In building insulation systems, the aluminum cladding is the first line of defense, protecting the internal insulation materials and the building structure. When standard 1060 aluminum coils fall short, and top-tier 5052 remains costly, the market demands a better solution. The 3004 and 3105 insulation aluminum coils are all-round products that achieve the perfect balance between strength, weather resistance, and cost.

Challenges Faced by Insulation Systems

🔹Deformation from Wind Pressure: Strong winds cause roaring, denting, or deformation of roof or facade cladding.

🔹Permanent Damage from Foot Traffic: Footsteps during construction or maintenance leave permanent dents, compromising aesthetics and seal.

🔹Insufficient Strength: Ordinary aluminum coils are easily scratched during processing or transportation, increasing waste and cost.

🔹Corrosion Risk: In mildly industrial areas or regions with high humidity, aluminum coils can develop white rust or spots prematurely.

🔹Cost-Performance Dilemma: The desire for better performance is often constrained by tight budgets.

If any of these points resonate with you, then the 3004 & 3105 insulation aluminum coil is the solution you’ve been looking for.

What are 3004 & 3105 Aluminum coils?

Aluminum coils, also called aluminum coils, belong to the aluminum-manganese-magnesium alloy family. They are “performance-enhanced versions” based on the widely popular 3003 alloy. By scientifically adding elements like Magnesium (Mg), they achieve an optimal balance of strength and formability.

• 3004 Aluminum coil: The Tough Performer

◆ Characteristics: High strength, high hardness, superior wind pressure resistance.

◆ Performance: Its strength is about 20% higher than conventional 3003 aluminum coils, making it the “impact-resistant beam” of insulation cladding. It is especially suitable for applications demanding extreme rigidity, such as large factory roofs, high-wind areas, and sections needing to withstand occasional loads.

• 3105 Aluminum coil: The Balanced All-Rounder

◆ Characteristics: Excellent overall performance, the king of cost-effectiveness.

◆ Performance: Its properties are similar to 3004, striking an excellent balance between strength, formability, and corrosion resistance. It is the ideal choice for upgrading from 1060 or 3003, suitable for almost all projects requiring performance above standard specs. It is truly a versatile “star product”.

Core Advantages of 3004 & 3105 Insulation Aluminum coils

✅ Stronger Protection: Say Goodbye to Deformation and Dents

Thanks to higher yield strength, 3004/3105 effectively resist strong wind pressure and bounce back better after construction foot traffic, minimizing permanent deformation. This means a longer service life, less maintenance, and a perfect building appearance.

✅ Excellent Weather Resistance: Unfazed by Environmental Challenges

They inherit the excellent atmospheric corrosion resistance of Al-Mn alloys. Combined with high-quality PE or PVDF coatings, they can easily withstand urban pollution, acid rain, and UV radiation, ensuring the building’s exterior remains new-looking for longer.

✅ Superior Workability: Easy Installation, Lower Waste

Despite their higher strength, they maintain good flexibility and formability, facilitating on-site cutting, bending, and hemming. This significantly improves construction efficiency and reduces material scrap rates caused by processing issues.

✅ High Cost-Effectiveness: Significant Performance Gain for a Reasonable Investment

Compared to the premium 5052 aluminum, 3004/3105 offer strength and safety far exceeding ordinary aluminum coils, while being more affordable. This is a precise investment of “spending less, achieving more,” effectively controlling total project costs while substantially enhancing project quality.

Application Scenarios

🔹Industrial Buildings: Steel structure factory roofs and walls (resisting wind pressure, vibration)

🔹Commercial Real Estate: Large shopping malls, logistics warehouses, sports stadiums

🔹Public Facilities: Insulation systems for airports, stations, schools, hospitals

🔹Windy Regions: All constructions in coastal cities and open plain areas

🔹Any Project Demanding Quality: The standard upgrade replacement for 1060/3003.

Selection Guide: 3004 vs. 3105, How to Choose?

✅ Pursuing maximum strength with a relatively sufficient budget?

→ Choose 3004. It provides the sturdiest protection for the most demanding conditions.

✅ Seeking a comprehensive upgrade and the best cost-performance ratio?

→ Choose 3105. It perfectly covers over 90% of mid-to-high-end needs and is the optimal solution for value.
