The excellent performance of sports wood flooring is inseparable from its carefully selected materials.
The top panel is mostly made of high-quality hardwood such as maple and oak. Maple has excellent toughness and moderate hardness due to its long fiber characteristics. It has excellent visual effects in competitions and TV broadcasts and has become the first choice of many gymnasiums. The thickness of the panel is usually 20mm, the width is about 65mm, and the length is 300-1000mm. It has grooves and flanges, which not only enhances the stability of the connection between panels, but also effectively prevents slipping. The middle load-bearing layer adopts a single-keel or double-keel structure, and usually uses wood treated with preservatives to resist erosion in a humid environment and ensure long-term stability. The keel spacing is generally set to 400mm to provide solid support for the panel. The stabilization layer often uses large-format OSB boards or plywood, with a size of about 1.22×2.44m and a thickness of more than 12mm, which further enhances the overall anti-deformation ability of the floor.
Elastic cushion is the key to sports wood flooring, and its materials include PU, rubber, recycled rubber, PVC, etc. These materials give the floor good shock absorption performance, effectively reducing the impact on the body when athletes jump and land. The bottom moisture-proof layer generally uses PE geotextile moisture-proof film to isolate the ground moisture and protect the entire floor system from moisture deformation. In addition, nails, paint and other auxiliary materials are also crucial. The panel nails use 50 mm L-shaped or T-shaped strong nails specially used for wood flooring to ensure that the panel is tightly connected to the keel; the paint must meet the requirements of a friction coefficient of 0.4 – 0.7, be free of triphenyl in terms of environmental protection, and have good wear resistance, anti-slip properties and light refraction.
