50*50&100*100mm Single-port Outdoor Aluminum Plastic Square Tube

Key Advantages

• Two size options: 50×50mm (suitable for small to medium spaces) and 100×100mm (suitable for large spaces or applications requiring prominent visual lines)
• Aluminum alloy profile: High material hardness (depending on alloy grade) with structural stability
• Wind pressure resistance: Maintains shape stability in outdoor and ventilated areas without deformation
• Single-port groove design: Allows easy alignment between adjacent square tubes with clean, straight lines
• Rust and corrosion resistance: Surface treatment (anodized or fluorocarbon-coated) resists salt-spray and chemical corrosion
• Fading and oxidation resistance: UV-stabilized coating provides stable color over long-term use
• Smooth, clean surface: Provides a regular visual effect after installation

Frequently Asked Questions

Q1: How to choose between 50×50mm and 100×100mm sizes?
50×50Mm suits small to medium spaces (ceiling height 2.8M-3.5M), providing higher grille density with finer visual detail. 100×100Mm suits large spaces (ceiling height above 4m) or applications requiring prominent tube lines and reduced visual obstruction. Select based on design specifications.

Q2: How are the square tubes installed?
Typical installation uses suspension: install hanger rods (spacing ≤ 1.2M) and main framing on the ceiling. Secure square tubes to the framing using dedicated clips or screws. Square tube spacing depends on design requirements (typically 50-200mm). For outdoor curtain wall applications, welding onto steel structural frames may be used.

Q3: Does the product surface require additional coating?
No. The product is factory-finished with anodized or fluorocarbon coating and is ready to install. For color changes, use metal-specific paints, though this adds installation steps.

Q4: Can the product be used outdoors?
Yes. The aluminum alloy and surface treatment provide UV and corrosion resistance, suitable for outdoor curtain wall grilles, sunshade components, and canopy decorations. Fluorocarbon coating is recommended for outdoor use due to superior weather resistance compared to anodized finishes.

Q5: How are the square tubes cleaned and maintained?
For indoor use, regular dusting with a feather duster or dry cloth is sufficient. For outdoor use, rinse with water. For stubborn stains, use a neutral cleaner with a soft cloth. Avoid steel wool pads or acid/alkaline cleaners.

Q6: Will joints between square tubes be misaligned?
The single-port groove design naturally aligns adjacent square tubes during installation. For long continuous runs, install each square tube independently and leave 1-2mm gaps at joints to accommodate thermal expansion. Ensure framing is level before installation.

Precautions

• Verify that framing is level and hanger rods are vertical before installation; Adjacent framing height difference not exceeding 2mm per 2 meters
• Storage requirements: Store flat on dry, level ground with stack height not exceeding 1 meter; Avoid heavy pressure that may cause deformation
• Use aluminum-specific saw blades (tooth spacing ≤ 3mm, negative rake angle) when cutting; Wear safety goggles, hearing protection, and gloves. Remove burrs with a file after cutting
• Handle carefully during transport and installation to avoid surface scratches or end deformation from impacts
• During suspension installation, ensure fasteners between square tubes and framing are tight to prevent rattling
• After installation, verify overall grille flatness with a level
• For outdoor installation, use stainless steel hanger rods and connectors to prevent galvanic corrosion
• Inspect color consistency across multiple batches before large-scale installation
• Avoid cleaning coated surfaces with strong acids, strong alkalis, or organic solvents
• For welded installations, ensure welding is performed by certified welders; Clean slag after welding and apply color-matched anti-rust paint to welded areas
