300*7mm Panel Board For Ceiling

Key Advantages

• Surface density of 2.3kg/m² provides clear reference for transportation and installation load calculations
• 300mm wide format: Reduces the number of seams per square meter by 33% compared to 200mm width products and by 17% compared to 250mm width products
• 7mm thickness: Section modulus higher than 5mm and 6mm panels, providing increased flexural stiffness
• Clip-in joint system: Requires no self-tapping screws or adhesives during installation
• Dense surface structure: Resists liquid and dust penetration, simplifying cleaning operations

Product Features

Application Scenarios

• Residential wet areas (kitchens, bathrooms, balconies, corridors)
• Residential dry areas (living rooms, bedrooms, dining rooms, full-house ceilings)
• Commercial spaces (retail stores, supermarkets, beauty salons, clothing shops, showrooms)
• Office spaces (open-plan areas, meeting rooms, reception areas, pantry areas)
• Hospitality (hotel guest rooms, hostel common areas, apartments)

Frequently Asked Questions and Precautions

Q1: How does the 300mm width compare to 200mm and 250mm widths in installation efficiency?
Panels required per square meter: 5 panels/m² for 200mm width, 4 panels/m² for 250mm width, and 3.33 panels/m² for 300mm width. The 300mm specification reduces the number of joining operations by approximately 1.7 per square meter and reduces total seam length by approximately 33%, making it suitable for large-area continuous ceiling installations.

Q2: What is the recommended framework spacing?
For 7mm thickness, recommended framework spacing does not exceed 550mm. Specific values depend on installation orientation and expected loads. For the 300mm panel width, framework should be oriented perpendicular to the panel length to fully utilize the panel's spanning capacity. Refer to product test reports or manufacturer installation specifications before installation.

Q3: Are there special considerations for handling and installing wide format panels?
The 300mm width panel has larger individual dimensions than standard sizes. Two-person handling is recommended to prevent bending deformation under self-weight. During installation, secure one end first and progressively clip into place along the length to avoid excessive localized force.

Q4: Does the 7mm thickness allow for wider framework spacing?
The 7mm thickness permits wider framework spacing than 5mm or 6mm thickness products. If framework spacing exceeds 600mm, consider upgrading to 8mm thickness or increasing framework density.

Q5: Does the wider panel affect cutting flexibility?
The 300mm width can be cut longitudinally on standard table saws or handheld circular saws. For narrow edge finishing where width is less than 300mm, cut panels to the required size. Use auxiliary support stands during cutting to prevent cracking due to overhang.

Precautions:

• Verify substrate flatness before installation: height difference ≤ 3mm when measured with a 2-meter straightedge
• Storage requirements: Store flat on dry ground with stack height not exceeding 1.2 meters; avoid edge-on storage as 300mm wide panels are prone to long-term bending deformation when stored on edge
• Use fine-tooth saw blades (tooth spacing ≤ 3mm) when cutting to minimize edge burrs
• For bathroom ceiling installations, combine with exhaust ventilation system to reduce condensation accumulation on the panel back surface
• Inspect color consistency across multiple batches before large-scale installation to ensure no visible color difference
• Avoid cleaning with solvents containing acetone, benzene, or strong alkaline agents
• The absolute thermal expansion of 300mm wide panels exceeds that of narrower panels. For large-area installations, reserve expansion gaps every 10 meters
