Wooden railing is primarily made from treated anti-corrosion wood using chemical agents, which is not a modification process but a protective measure, thus retaining the original physical properties of the wood. The original use of the wood remains with the anti-corrosion wood, and its applications are expanded due to the chemical properties of the anti-corrosion wood.

Today, treated wood is widely used in the maintenance and renovation of ancient buildings in our country, as well as in municipal projects, parks, and residential communities for applications such as treated wood fences, tree pit railings, wooden walls, walkways, leisure paths, benches, planters, railings, trash bins, waiting halls, and scenic bridges, among other outdoor woodwork. It can also be utilized in indoor decorative pieces.

Due to the varying compositions of different preservatives, it's necessary to differentiate the use of wood treated with different preservatives for various locations.

Treated wood retains the wood's natural, eco-friendly visual, tactile, and auditory properties, while also enhancing its unique anti-corrosion features and flame retardancy. It's widely used in industries, agriculture (crop support wood), construction, and more. As people's demands for living environments improve, its applications have gradually expanded to wooden别墅, flooring platforms, porches, wooden bridges, garden furniture, plant stands, pots, and other various outdoor wood products, satisfying people's aesthetic concepts of returning to nature and simplicity. Developed countries in Europe and America began using it extensively in the 1950s.
