Description

Three-layer rectangular plastic-wood section bar

Technical Field

The utility model discloses what three-layer rectangle was moulded wood section bar related to is a combined material section bar, belongs to combined material and novel chemical building materials technical field.

Background

The section bar is an object with a certain geometrical shape, which is made of iron, steel, plastics or other materials with certain strength and toughness through the processes of rolling, extruding, casting and the like, and has a certain appearance size and a certain fixed cross section shape.
