Due to the manufacturing process, slight variations in color and surface appearance are unavoidable. These may include dye lot differences, flecks, specks, or other minor irregularities. For specific details, please contact the manufacturer.
All panel sizes are nominal and subject to tolerances of ±1/8”. Precise fitting may require on-site adjustment by the purchaser. Additional factors—such as dye lot variation, lighting conditions, pattern alignment, directional material differences, and dimensional changes caused by environmental conditions—may affect the final appearance. Projects with strict visual requirements should be identified in advance for special consideration before ordering.
