50*75mm Double Port PVC Square Tube

Key Advantages

• Double port structure: Open ends on both sides – facilitates connection and fixing – high installation stability
• 50×75mm dimensions: Rectangular cross-section – width greater than height – flat and square visual proportion
• PVC material: Virgin material extrusion – smooth surface – uniform color
• Water and moisture resistant: Non-absorbent material – suitable for various indoor environments
• Insect and mold resistant: Non-wood material – not susceptible to insects – surface does not support mold growth
• No painting required: Factory-finished surface – no on-site coating needed
• Easy to maintain: Smooth surface – wipe with a damp cloth
• Simple assembly: Compatible clip or hanger systems – high construction efficiency
• Clean appearance: Square cross-section with crisp lines

FAQ and Precautions

Q: What is the difference between double port PVC square tubes and single port square tubes?
A: Double port square tubes have open ends on both sides, used with double-ended connectors for stronger overall integration, suitable for long-span continuous arrangements. Single port tubes have one open end and one closed end or a single opening direction, with different installation methods and visual effects. Selection depends on specific suspension systems and design requirements.

Q: Why is the 50×75mm dimension wider than it is tall?
A: The flat square tube with 50mm height and 75mm width creates a stronger horizontal visual extension when installed, suitable for creating an open, crisp linear feel. Ideal for applications with ceiling height limitations where horizontal visual impact is desired.

Q: What is the difference between virgin PVC material and recycled material?
A: Virgin material provides uniform color, better flexibility, a smooth surface without impurities, and resists discoloration or embrittlement over long-term use. Recycled material may contain impurities with lower color uniformity and mechanical properties. This product uses virgin PVC material.

Q: How are double port square tubes connected and fixed?
A: Typically using compatible cross clips, straight connectors, or hangers. Insert tube ends into connectors, then suspend from furring channels via hanger rods. Connectors are made of metal or PVC, depending on the system.

Q: Can it be used outdoors?
A: This product is designed for indoor decoration. Prolonged outdoor exposure to UV radiation and extreme temperature changes may cause PVC material aging, fading, or embrittlement. Outdoor use is not recommended.

Precautions

• Check ceiling substrate flatness and load capacity before installation. Recommended suspension rod spacing ≤1200mm, depending on tube length and cross-section.
• Use a fine-tooth saw blade for cutting to maintain straight edges. Remove burrs from cut ends to ensure smooth connector insertion.
• Use compatible connectors and hangers for installation, ensuring tight fit between tube ends and connectors. Maintain uniform spacing and parallel alignment during installation.
• Clean with a soft cloth and neutral detergent. Avoid steel wool, stiff brushes, abrasive cleaners, or strong acids/alkalis. Avoid wiping with organic solvents such as alcohol or thinner.
• Store products flat with stack height not exceeding one meter. Avoid heavy pressure that may deform tubes. Avoid scratches from sharp objects.
• Protect product surfaces and ends during transport. Avoid impact that may damage tube ends or scratch surfaces.
• For large-area ceiling installations, install the furring channel grid and connector positioning lines first, then insert tubes sequentially. Keep tube surfaces clean during construction.
• For long-span installations (single length exceeding 3000mm), add intermediate hangers to prevent sagging deformation.
• Avoid using transparent adhesive tape for temporary fixing on the surface, as residue may damage the finish.
• For curtain wall partition applications, ensure top and bottom fixing points are secure and tube verticality meets requirements.
