The section bar can be used independently and can be further processed into other manufactured products, and the section bar is widely applied to the fields of building structures, manufacturing and installation and the like.

The shapes and the structures of products such as guardrails, handrails, a rack, a separation fence, a grape trellis and the like are simpler, but the parts needing to be connected are more, and the products can be conveniently connected with other parts by using sectional materials with clamping grooves, so that the installation efficiency can be effectively improved on the premise of meeting the use requirements. Traditionally, the section bars used for manufacturing the products mainly comprise wood section bars, metal section bars, rigid plastic section bars, concrete section bars and the like. The wood section has natural wood texture, brings enjoyment close to nature to people, has good heat preservation effect, but has some obvious limitations such as chromatic aberration, easy cracking and deformation, poor water resistance, possibility of being damaged by worms and the like, and trees are cut down to destroy natural resources when the wood section is produced, so that water and soil conservation and environmental protection are influenced; the metal section has high strength, is non-combustible and is not easy to deform, but has some obvious limitations, such as poor repairability, poor touch, high energy consumption in the production process, easy decay and the like; the hard plastic section has light weight and good corrosion resistance, but has the limitations of not ideal heat preservation effect, easy deformation, higher price and the like; the concrete section has high strength and good firmness, but is heavy and inconvenient to manufacture, and building garbage and the like are easy to generate after the section is abandoned.

In recent years, with the enhancement of the environmental protection consciousness of people, the plastic-wood composite material which is wide in raw material source, environment-friendly, renewable and recyclable is more and more valued by people. The composite material is a composite material with wide application, which is processed and manufactured by taking waste plastic, wood powder and the like as raw materials, and the processing principle is as follows: waste plastics and agricultural and forestry waste powder are mixed according to a certain proportion, and special auxiliary agents are added, and the mixture is made into a section bar with a certain shape through the processes of high-temperature melting, mixing, forming and the like. The wood plastic has the processing performance similar to that of wood, can be sawed, nailed and planed, has excellent solvent resistance and corrosion resistance, does not propagate bacteria, is not easy to be damaged by worms and does not grow fungi, and the density and other characteristics of the plastic material can be changed by adding different additives, thereby meeting the special requirements of ageing resistance, static resistance, flame retardance and the like. Meanwhile, the plastic-wood composite material has the characteristics of wood appearance, higher hardness than that of a plastic product, homogeneous material, stable size compared with wood, difficult crack generation, no wood scab, no twill and the like; it has the processability of thermoplastic plastics and small abrasion to equipment; toxic chemical substances are not required for treatment, and formaldehyde is not contained; can be recycled after being discarded, is beneficial to environmental protection and the like.
