Let’s first look at the parameters of professional NBA basketball court flooring:
Professional-level basketball stadium sports wooden flooring can be analyzed from these aspects:
Durability performance : The wood floor material is corrosion-resistant, has anti-friction treatment agent penetration, and can penetrate anti-corrosion treatment agents.
Physical properties: Maple wood is hard and heavy, has good strength properties, has particularly high anti-friction and anti-wear strength, and also has good resistance to steam bending. It is more suitable for flooring in indoor sports venues.
Processing properties: Hard maple dries slowly and has a large shrinkage rate, so it is prone to performance changes. To install nails and screws, it is recommended to use professional wood floor nailing tools. Handled with care, it can be machined well, turns well, is glued satisfactorily, and can be sanded and polished to give an excellent surface.
Moisture-proof layer: PE geotechnical moisture-proof film
Elastic cushion: a nationally patented elastic rubber cushion, which mainly provides shock-absorbing performance for the system.
Bear-bearing layer: The load-bearing layer can use single keel or double keel, and usually requires the use of preservatives for anti-corrosion treatment. The keel spacing is generally set to 400mm. According to whether the keel is fixed to the ground and what kind of fixing method is used, sports wooden flooring can be divided into suspended system, fixed suspended system and fixed system.
Paint: Paint is divided into two types: UV paint applied at the factory and polyurethane paint applied at the construction site, both of which need to meet the friction coefficient requirements of 0.4-0.6. In terms of environmental protection, it is necessary to be free of triphenyl (i.e., benzene, toluene, and xylene) and tribenzene-free (i.e., paint, curing agent, and diluent do not contain benzene), and have good wear resistance, anti-skid properties, and light refraction. Performance is good in terms of degree and so on.
Stringing: Use the scribing paint that matches the panel paint.
Skirt: 80mm60mm type solid wood skirting. Stable layer: Usually larger-format boards are used, mainly OSB boards, plywood, etc. The size is basically 1.22*2.44m, and the thickness is mostly above 12mm.
Nails: Panel nails are made of 50 mm L-shaped or T-shaped strong nails special for wooden floors; the stable layer is usually connected to the keel by U-shaped nails.
Panel: The panel can be made of solid wood composite or solid wood board. High-quality hardwoods are selected as tree species, and the more commonly used ones are hard maple, ash, oak, beech, etc. Since maple is a long-fiber tree species with good toughness and moderate hardness, and has the best viewing effect during games and television broadcasts, most stadium panels in the world are made of maple. The panel moisture content must not exceed the local equilibrium moisture content. The specifications of maple panels imported from abroad generally have thicknesses of 20mm and 26mm, and widths of 38mm and 57mm, etc. Most of the sizes of domestic boards are 22mm thick, with grooves and flanges.
Now you know why NBA professional basketball court floors are so expensive!
