Bothbest is a FSC certified bamboo factory based in China starting the manufacturing since 2001, mainly supplying bamboo flooring, bamboo decking and bamboo plywood.

Vertical carbonized solid bamboo flooring brings together refined texture, structural stability, and the warm tone produced by controlled carbonization. To appreciate what makes this material distinctive, it helps to understand the nature of solid bamboo flooring as a category. Solid bamboo flooring is made from strips of bamboo cut from mature culms, processed to remove natural starches, dried to reduce moisture, laminated under pressure, and then machined into smooth planks. Unlike engineered bamboo, which uses a thin wear layer over a composite core, solid bamboo flooring maintains a consistent, dense structure throughout the entire board. The fiber strength, uniformity, and durability that come from this construction give the material a firm, satisfying feel underfoot and a long service life when maintained properly.

Within this type of flooring, the vertical grain pattern offers a distinct appearance. Vertical grain is created by turning each bamboo strip on its side during lamination so the narrow edge faces upward. When these slender strips are aligned and pressed together, the final surface displays fine, linear details with small, repeated lines running the entire length of the board. This produces a clean, orderly aesthetic with subtle texture. Unlike horizontal grain, where visible bamboo nodes are emphasized, vertical grain downplays the node pattern and focuses on a sleek, contemporary look. Many designers choose vertical grain for interiors that call for understated elegance or a smoother, more uniform surface appearance. The tightly aligned strips also contribute to excellent stability across the width of the plank, making the boards less susceptible to surface irregularities.

Carbonization adds character by deepening the natural color of the bamboo. Raw bamboo typically shows pale yellow or cream tones. Through carbonization, heat and steam penetrate the material, causing the naturally occurring sugars in the bamboo fibers to caramelize. This process produces warm brown hues that vary from gentle amber to deeper toffee shades. Because the color permeates the entire strip rather than sitting on top like a stain, the tonal depth remains consistent even after sanding or long-term wear. The softer, richer coloring of carbonized bamboo works well in spaces where a comforting, mellow atmosphere is desired. It complements a wide variety of furnishings and architectural styles, providing an inviting backdrop without overpowering the room.

Vertical carbonized solid bamboo flooring is produced in several standard and customized sizes to match different project needs. Typical thicknesses range from 10 to 15 millimeters, giving installers flexibility depending on whether the flooring is going over plywood, concrete, or existing substrates. Widths often fall between 96 and 130 millimeters, though narrower or wider options are also available for specialized applications. Lengths can be short, medium, or extended, allowing builders to create either rhythmic patterns or broader, more continuous visual lines. These various dimensions make it easy to adapt the flooring to compact rooms, open layouts, or commercial settings. Whether the goal is a refined, patterned aesthetic or a more expansive feel, the size range accommodates both practical installation requirements and design preferences.

The manufacturing process for vertical carbonized solid bamboo flooring follows a detailed sequence designed to ensure consistency and durability. Production starts with the selection of high‑quality bamboo that has reached an optimal age of about five to six years. At this maturity level, fiber density is strongest, which supports hardness and durability in the finished planks. After harvest, the culms are cut into long strips, and the outer green skin is removed. For carbonized material, the strips undergo controlled heat and steam treatment to achieve the desired darker shade. The strips are then dried carefully so moisture content reaches a stable level. This drying step is critical because it limits expansion and contraction once the flooring is installed.
