Relief is a kind of sculpture. The sculptor carves the image he wants to shape on a flat plate, making it separate from the plane of the original material. Relief is the product of the combination of sculpture and painting. It deals with objects in a compressed way, and displays three-dimensional space by perspective and other factors. It is only for one side or two sides to see. The reliefs are usually attached to another plane, so they are used more in architecture and can be seen on utensils and implements. Due to its compression characteristics, it occupies less space, so it is suitable for decoration in a variety of environments. In recent years, it has played an increasingly important role in urban beautification. The relief is as rich and colorful as the round sculpture in content, form and material. The materials of relief include stone, wood, ivory and metal. The relief is a semi vertical sculpture whose image shape protrudes from the stone surface (as opposed to the relief). It can be divided into light relief and high relief according to the depth of stone removal in image modeling. The bas reliefs are single level statues with relatively simple contents; The high relief is a multi-level statue with complicated contents. The carving technique and expression style of relief are basically the same as those of round sculpture. Many ancient and modern large-scale memorial buildings, high-end mansions and private houses are equipped with such decorations. Their main works are wall blocks, flower windows, dragon columns (early) and column bases.

It is a three-dimensional plastic art to use certain material materials to produce works of art with solid image. Because the production methods are mainly sculpture and molding, it is called sculpture. According to the production process, sculpture can be divided into two categories: sculpture and sculpture. Subdivision is divided into carving, carving, molding, chiseling, carving, casting and other skills and techniques. According to genre, sculpture can be divided into memorial sculpture, urban garden sculpture, sculpture, tomb sculpture and exhibition sculpture. According to the style, sculptures can also be divided into head portrait, bust portrait, bust portrait, full body portrait, group portrait, etc. According to the technique and form of expression, sculpture can be divided into three categories: round sculpture, relief sculpture and openwork sculpture. Round sculpture, also known as "muddy sculpture", is a three-dimensional sculpture that is not attached to any background and can be viewed from all sides. The round sculpture is characterized by a solid image standing in space. When creating it, one must take into account its sense of volume and weight. When shaping the image, one must also take into account that people watch it from different angles. Relief, also known as "relief", is to carve a convex artistic image on the plane. According to the different degrees of surface relief, relief can be divided into high relief (high and low relief, deep relief) and low relief (low and low relief, shallow relief). The openwork is between the round sculpture and the relief sculpture. On the basis of the relief sculpture, it is made by hollowing out the background, but it does not leave the plane, just like a round sculpture attached to the plane background.

Exterior wall decorative panel is a new type of integrated material for building exterior wall decoration and insulation developed in recent years, which is composed of polyester baking paint or fluorocarbon paint, carved aluminum zinc alloy steel plate, polyurethane insulation layer and glass fiber cloth; Tunchang Sculpture processing It is mainly used for exterior wall decoration and energy-saving reconstruction of gymnasiums, libraries, school and hospital office buildings, villas and other buildings; The main functions are building decoration, heat preservation, energy conservation, heat insulation, sound insulation, waterproof and mildew proof.
