6 Key Points to Check When Inspecting Commercial Plywood
Posted by Đỗ Tiến Hải at 21/09/2023
Commercial plywood is widely used in furniture, construction, packaging, and interior applications. To ensure durability and performance, proper inspection is essential before purchasing or using it in production. Below are six key points to help assess plywood quality efficiently.
1. Check Thickness Consistency
Use a caliper or measuring tape to check the thickness of the plywood sheet at multiple points. Uniform thickness ensures stability during processing and helps avoid surface irregularities after installation.
2. Inspect Surface Smoothness and Cleanliness
Look for a smooth surface that is free from cracks, knots, dents, stains, or rough patches. A good-quality sheet will have a clean and even surface that’s suitable for painting or laminating.
3. Examine the Core Structure
Cut or inspect the edge of the plywood to observe the inner core. The core layers should be evenly layered, without gaps, overlapping, or visible voids. A well-constructed core improves strength and prevents warping.
4. Test Adhesive Bonding Strength
Gently flex or apply pressure to a corner of the sheet to test its bonding quality. Good plywood will not delaminate or peel between layers. Strong adhesive bonds are critical to ensure structural integrity over time.
5. Measure Moisture Content
Use a moisture meter to ensure the sheet’s moisture level falls between 8% and 14%. Excess moisture can cause swelling, mold, and delamination, especially in humid climates.
6. Assess Flatness and Warping Resistance
Place the plywood sheet on a flat surface to check for any warping or bends. A quality sheet will lie flat and retain its shape even under environmental stress or over time.
Why Inspection Matters
By following these six key inspection steps, you reduce the risk of product failure, save on repair costs, and ensure end-user satisfaction. Whether you are a trader, furniture maker, or contractor, investing a few minutes in inspection can lead to long-term value and consistent quality.
