Aluminum Grating Factory Direct | 6063-T6/6061 Aluminum Alloy | Press-Locked/Welded Process | Lightweight Corrosion-Resistant Solution
In applications where reducing structural burden is critical, is traditional steel grating overloading your main steel structure? In marine climates or humid environments, are rust issues forcing frequent replacements?
Aluminum grating—the perfect solution to the dual challenges of “lightweight” and “corrosion resistance.”
With 15 years of expertise in aluminum alloy deep processing, we operate fully automatic press-locked production lines and anodizing surface treatment workshops. From 6063-T6 to 6061 aluminum alloy, from industrial maintenance platforms to five-star hotel facades, we deliver premium aluminum grating solutions featuring weight only 1/3 of steel, never rusting, and 50 years maintenance-free.
Why Choose Aluminum Grating? Why Choose Us?
1. Material is the Advantage: Choose the Right Aluminum Alloy – Lightweight Yet Strong
The core value of aluminum grating lies in the perfect balance between lightweight and corrosion resistance. We strictly select national standard 6063-T6/6061 aluminum alloy prime materials, ensuring stable chemical composition and excellent mechanical properties:
| Grade | Characteristics | Application Scenarios |
| 6063-T6 Aluminum Alloy | The most widely used aluminum alloy in construction, offering excellent extrusion formability and surface treatment effects. After heat treatment, it achieves moderate strength with a fine, uniform surface. | Ceilings, building curtain walls, shading systems, interior partitions—decorative applications |
| 6061 Aluminum Alloy | High-strength aluminum alloy containing magnesium and silicon. Produced through heat treatment and pre-stretching, it offers excellent workability, good weldability, high toughness, and minimal deformation after processing. | Industrial platforms, maintenance walkways, stair treads—load-bearing applications |
| Special Alloy Customization | For special requirements such as offshore platforms or chemical environments, we offer higher-grade specialty aluminum alloy customization. | Extreme environments |
Core Advantage: With a density of only 1/3 of steel, aluminum grating significantly reduces requirements for supporting structures under the same load, substantially lowering配套 costs.
2. Two Mainstream Processes – Meeting Different Application Scenarios
We offer two mature and stable aluminum grating manufacturing processes, precisely matched to your project needs:
| Process Type | Press-Locked Type (Swiwelder Process) | Welded Type |
| Manufacturing Method | Bearing bars are slotted, cross bars inserted and permanently locked under high pressure | Cross bars welded to bearing bars using argon arc welding |
| Product Features | No weld points, strong connection, high precision, excellent appearance, no weld marks on surface | High strength, good stability, suitable for standard load requirements |
| Recommended Scenarios | Building curtain walls, ceilings, commercial decoration, high-end fencing | Industrial platforms, maintenance walkways, stair treads, trench covers |
3. Multiple Section Designs – Precisely Matching Load Requirements
We offer various bearing bar section profiles to meet different anti-slip and load-bearing requirements:
Flat Type: Standard rectangular section, smooth surface—suitable for普通 walkways and platforms
Serrated Type: Anti-slip teeth on upper surface—ideal for wet, oily, or sloped environments; extremely high slip resistance coefficient
I-Beam Type: I-shaped section—lighter weight under same load capacity, lower cost; textured upper and lower surfaces increase friction
T-Type: T-shaped section—balances load-bearing and aesthetics
Dovetail Type: Diamond-shaped square bars flush with bearing bar surface—stronger load-bearing surface, unique appearance
4. Surface Treatment: Beyond Corrosion Protection – Aesthetic Presentation
A major advantage of aluminum grating is the ability to achieve rich colors and textures through surface treatment:
| Surface Treatment | Characteristics & Applications |
| Anodizing | Forms a dense oxide film—high hardness, good wear resistance, matte metallic finish, excellent corrosion resistance |
| Powder Coating | Rich colors (champagne gold, matte black, silver white, bronze, etc.), strong adhesion—suitable for commercial spaces and architectural decoration |
| Fluorocarbon Coating | Excellent weather resistance, corrosion resistance, and UV resistance—ideal for long-term outdoor use |
| Wood Grain Transfer | Simulated wood grain effect—combines the aesthetics of wood with the durability of aluminum |
Five Core Advantages of Aluminum Grating
✅ Lightweight with High Strength – Reducing Structural Burden
With density only 1/3 of steel, aluminum grating dramatically lowers load requirements on main steel structures, reducing foundation costs. Handling and installation are more convenient, significantly improving construction efficiency.
✅ Exceptional Corrosion Resistance – 50 Years Without Rust
Aluminum naturally forms a dense oxide layer in air, resisting damp, acids, alkalis, and harsh environments without additional anti-corrosion treatment. Especially suitable for marine climates, chemical plants, food processing facilities, and other high-corrosion scenarios.
✅ Aesthetic Appeal – Elevating Project Quality
With metallic luster and diverse surface treatments, aluminum grating meets the aesthetic demands of modern architecture. Widely used in commercial complexes, airports, high-speed rail stations, luxury residences, and other venues with high visual requirements.
✅ Fire Safety – Non-Combustible
Aluminum alloy is a non-combustible material—it will not burn when exposed to fire and releases no harmful gases, complying with strict fire safety regulations for public buildings.
✅ 100% Recyclable – Environmentally Friendly
Aluminum can be 100% recycled, meeting green building material policies and reducing the environmental impact of construction waste.
