Quality Control Checkpoints For Bamboo Flooring

Bamboo flooring with strict quality control is the key point to make sure it is top and consistent quality. Bamboo flooring is in the process with 30% of hand work, so quality defects could happen if there is no strict quality control.

In our factory, we have a systemized, strict and consistent quality control rules and checkpoints. Every piece of bamboo flooring will go under this quality control line, we sort out every defected piece before package.

1. Bamboo raw material, Inspect culm quality and select prime lengths for products.

Cut to 30 to 35 feet in the field, culms are inspected at the factory for age, cracking, pests and general health. The premium part of each length is selected for products and then cut into slats. The remaining culm lengths are sent to nearby factories for use in other non-bothbest products.

2. Moisture control, Check kiln-dried slats to confirm moisture content of approximately 6 to 9 percent.

After the slats have been treated in a natural borate solution to kill pests and mildew, they rest in the kiln drying room for four to five days. This stabilizes the bamboo to prevent the likelihood of cupping, delamination, and expansion and contraction of end products.

3. Slat grading and sorting

Inspect slats for grain, quality, color consistency, thickness and length, and bundle by function in the end product (e.g., top "wear" layer or substrate).

After the slats are first planed, they are inspected and graded for use in flat grain or vertical grain layers of our products. Those with the most consistent grain and color are reserved for use in the visible top or "wear" layer. Others form the strong cores or substrates of various products.

4. Moisture control

Kiln dry bundles of slats and confirm moisture content of approximately 6 to 9 percent before lamination.

Bamboo is a natural material that, like other hardwoods, absorbs and loses moisture from the air around it. By fastidiously acclimating the slats at various points in the manufacturing process, we ensure the optimal conditions for each phase of manufacturing which also ensures a more durable end product.

5. Lamination

Double-check each slat layer for consistent color and thickness before proceeding with adhesive lamination on the hydraulic press

Check adhesive coverage on slats

Inspect top layer to ensure that best slats are presented as wear surface

Check hydraulic press plates for cleanliness, duration, temperature and pressure

6. Blank grading and sorting

Inspect grade and sort planks for defects, voids, delamination or inconsistent coloration.

7. Moisture control

After being stored in a humidity-controlled warehouse for two weeks, blanks are checked for moisture content of approximately 6 to 9 percent

8. Milling

Test run and sample plank inspection. Plank inspection every 10 minutes to ensure consistent milling tolerances from production run to production run

9. Sealing and sanding

Inspect tongue-and-groove polyurethane seal

Sand product one time and inspect for sanding quality

Sealing the tongue-and-groove edge of products is an extra step that helps prevent moisture absorption after installation and ensure long product life.

10. Finish line

Sand planks again before finishing

Inspect the 7-coat German aluminum oxide/polyurethane finish coatings

11. Packaging

Inspect each carton for correct type and quantity of completed planks

Final color inspection of planks

Check for correct SKU marked on carton
