Product Overview
Aluminum Baffle Ceiling, also known as aluminum U-channel, aluminum square tube, or aluminum strip ceiling, is a modern suspended ceiling system composed of individual linear aluminum profiles arranged in parallel rows with open gaps between them. Each profile is cold-rolled or extruded from high-quality aluminum alloy (typically 3003 / 6063) into a U-shaped or rectangular hollow cross-section. The open design allows for excellent airflow, natural light integration, and easy access to the plenum space above.
Aluminum baffle ceilings are widely used in commercial and public interiors - shopping malls, airports, metro stations, office lobbies, exhibition halls, and modern retail spaces - where a sleek, linear aesthetic and functional ceiling performance are equally important.
Key Features & Advantages
- Linear aesthetic: creates a clean, directional visual flow that elongates spaces.
- Open-ceiling flexibility: gaps between baffles provide ventilation, acoustic control, and easy service access.
- Lightweight: aluminum construction minimizes structural load on the building.
- 100% fireproof (Class A): all-metal material - non-combustible per GB 8624 / ASTM E84.
- Moisture & corrosion resistant: ideal for humid or coastal environments.
- Wide design range: multiple widths, heights, spacing, colors, and finishes to match any interior scheme.
- Easy installation: clip-on or spring-tee suspension onto standard T-grid or dedicated carrier rails.
- Fully recyclable: supports green building certifications (LEED, BREEAM).

Aluminum Square Tube (Baffle Ceiling) FAQ
Q: 1. What is an aluminum square tube?
A: An aluminum square tube is a hollow, rectangular aluminum extrusion used primarily for linear baffle ceiling systems, decorative wall cladding, and architectural screening. Made from 6063-T5 aluminum alloy, it offers excellent corrosion resistance, lightweight properties, and modern aesthetic appeal. Common profiles include U-channel, rectangular tube, and custom shapes, available in widths from 20mm to 300mm and heights from 20mm to 300mm.
Q: 2. What are the standard specifications?
A: Common specifications:
• Profile: U-channel, square tube, rectangular tube, round tube
• Width: 20mm, 30mm, 50mm, 75mm, 100mm, 150mm, 200mm, 300mm
• Height: 20mm, 30mm, 50mm, 75mm, 100mm, 150mm, 200mm, 300mm
• Wall thickness: 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm
• Standard length: 3m, 4m, 5.8m, 6m (custom lengths available)
• Alloy: 6063-T5
• Surface finishes: powder coating, PVDF, anodizing, wood-grain transfer
Q: 3. What is the minimum order quantity (MOQ)?
A: The typical MOQ is 100–300 linear meters or 200–500 square meters, depending on profile size, wall thickness, and surface finish. Small custom profiles may have higher MOQs. Bulk orders benefit from tiered pricing. Please provide your profile drawings or specifications for a precise quotation.
Q: 4. Where are aluminum square tubes used?
A: Common applications:
• Commercial ceilings: shopping malls, airports, metro stations, office lobbies
• Baffle ceilings: open-cell linear ceiling systems for modern interiors
• Exterior facades: sun-shading screens, decorative cladding, ventilation grilles
• Partitions: office dividers, space separators, decorative screens
• Furniture: shelving systems, display racks, modern furniture frames
• Landscape: pergolas, fencing, outdoor shading structures
Q: 5. What are the advantages over traditional ceiling materials?
A: ① Lightweight: 60% lighter than steel, reducing structural load and installation cost
② Corrosion resistant: excellent performance in humid and coastal environments
③ Modern aesthetics: clean lines with a minimalist, industrial look
④ Easy installation: clip-in or screw-fixed systems, fast assembly with minimal tools
⑤ Low maintenance: powder-coated surface resists dust and requires only occasional wiping
⑥ Fire safety: non-combustible metal, rated Class A fire-resistant
⑦ Eco-friendly: 100% recyclable aluminum, meeting green building standards
Q: 6. What surface finishes are available?
A: • Powder coating: wide color range (RAL, Pantone matching), durable, cost-effective - 10–15 year lifespan indoors
• PVDF (Fluorocarbon): superior UV and weather resistance - 20+ year lifespan for exterior use
• Anodizing: hard metallic finish, scratch and corrosion resistant - ideal for high-traffic areas
• Wood-grain transfer: realistic wood texture for warm, natural interiors
• Brushed / polished: metallic luster for high-end commercial projects
• Custom colors: color matching against provided samples is available
Q: 7. Is the product fire-resistant?
A: Yes. Aluminum square tubes are made from 6063-T5 aluminum alloy and are rated Class A fire-resistant (non-combustible) under GB 8624. The metal does not burn, melt at typical fire temperatures, or release toxic fumes. Powder coating and PVDF finishes applied to the surface are also flame-retardant. Third-party fire test certificates are available upon request.
Q: 8. What is the typical production lead time?
A: • Stock profiles with standard powder coating: 5–7 working days
• Standard size, custom color/powder coating: 10–15 working days
• Custom profile with special finish: 15–25 working days
• Large-volume orders: timeline adjusted based on production schedule
Actual delivery depends on order volume and factory capacity. Rush orders may be accommodated - please contact our sales team.
Q: 9. How are the products packaged and shipped?
A: Packaging: Each tube is individually wrapped in PE protective film, bundled with plastic straps, and packed in reinforced wooden crates or pallets with corner protectors. Custom lengths are packed in dedicated crates.
Shipping:
• Domestic: dedicated truck or LTL logistics with door-to-door delivery
• International: FCL/LCL sea freight (FOB/CIF terms), 20GP or 40HQ containers
Long profiles (up to 6m) are shipped in open-top containers or flat racks when necessary. Our protective packaging minimizes transit damage.
Q: 10. How are aluminum square tubes installed?
A: Installation methods:
• Clip-in system: tubes snap into pre-installed spring clips on a keel grid - fastest method for ceilings
• Screw fixing: tubes secured with countersunk screws to sub-frame - for facades and partitions
• Hanging system: adjustable wire suspension for suspended baffle ceilings
• Bracket mounting: L-brackets fixed to walls or structural members - for cladding and screens
Installation should follow the supplier's guide. Professional installers are recommended for large commercial projects. We offer installation drawings and technical support.
