The invention discloses a handrail formed by coextruding a wood plastic steel core. The handrail comprises a handrail (1) and is characterized in that the handrail (1) comprises a rectangular steel tube (11) and a coating layer (12) which is coextruded on the outer surface of the rectangular steel tube (11); two open grooves (121) are formed in the lower edge of the coating layer (12); the coating layer (12) is made from a wood plastic material. The handrail disclosed by the invention is high in strength, large in rigidity, good in corrosion resistance, easy to manufacture, low in cost, environment-friendly, beautiful and long in service life.
Description
technical field [0001] The invention relates to building decoration materials, in particular to a wood-plastic steel-core co-extruded railing for expressways. Background technique [0002] Most of the existing guardrails for highways are made of stainless steel pipes or aluminum alloy pipes. Although such structures have a long service life, their production costs are high, and their production is labor-intensive and time-consuming, resulting in low production efficiency. Contents of the invention [0003] The object of the present invention is to provide a wood-plastic-steel core co-extruded railing with high strength, high rigidity, good anti-corrosion performance, easy manufacture, low cost, environmental protection, beautiful appearance and long service life. [0004] In order to achieve the above object, the present invention includes a railing, the railing includes a rectangular steel pipe and a cladding layer co-extruded on the outer surface of the rectangular steel...
