| Maple | Light-colored hardwood with a fine, generally even grain. Its pale surface provides clear contrast with darker squares. | Light squares, solid boards, and veneer faces | Solid panels, laminated panels, or maple veneer over a stable core | Check for consistent color, smooth sanding, clean edges, and well-matched square colors. |
| Black Walnut | Dark brown hardwood with attractive grain; natural color can vary between pieces. | Dark squares, borders, and premium-style boards | Solid panels, laminated construction, or walnut veneer over a stable core | Agree on acceptable color variation and inspect for open defects, veneer bubbles, and finish consistency. |
| Beech | Pale to pinkish-brown hardwood with a fine, fairly uniform texture. | Light squares and painted or stained components | Solid panels, edge-glued panels, or veneer construction | Check for blotchy stain, raised grain, and movement-related gaps; confirm the finish is fully cured. |
| Birch | Light-colored hardwood with a relatively fine grain; appearance and color vary by species and source. | Light squares, face veneers, and laminated boards | Solid panels, plywood core with veneer faces, or edge-glued panels | Check veneer matching, surface smoothness, square alignment, and the quality of the core and edge treatment. |
| Oak | Hard, prominent-grained hardwood; open pores are characteristic of many oak species. | Borders, frames, and boards with a visible grain pattern | Solid panels, laminated panels, or oak veneer over a stable core | Confirm that pores are filled or finished as specified and inspect joints for gaps or unevenness. |
| Rubberwood | Plantation-grown hardwood commonly used for furniture and indoor products; typically light in color and suitable for staining. | Painted, stained, and value-focused board programs | Finger-jointed panels, edge-glued panels, or veneer-faced construction | Review the joint layout, adhesive bonding, moisture condition, and finish uniformity across batches. |
| Acacia | A broad group of hardwoods with species-dependent color, grain, and density; some sources show strong grain variation. | Decorative boards and solid-wood borders | Solid panels, edge-glued panels, or veneer construction | Specify the exact species and visual grade where possible; inspect for color range, checks, and consistent construction. |
