In the membrane structure industry can be broadly divided into two major categories of building types:

The first Category: structural class structure of the membrane structure of the main components of the building is the membrane material, steel structure and cable, different membrane materials and cables, the performance and price vary. In the structure of the model can be divided into the following two categories:1. Skeleton membrane structure: this kind of membrane structure is fixed in the fine steel, space truss or other sturdy frame, called skeleton membrane structure.

2. Tension-type membrane structure: tension-type membrane structure, also known as tensile membrane structure, only the use of simple support system and membrane material of its own tension characteristics, constitute such membrane structure. Unlike traditional structures, membrane structures are dominated by flexible films and cables. To design the membrane structure, it is necessary to understand its material. The thin film material used in construction engineering can be divided into two categories: fabric-like and non-fabric-type membrane materials. The fabric-like film is commonly used PVDF coating coated polyester fiber fabric (hereinafter referred to as PVC film) and PTFE coating covered fiberglass fabric (hereinafter referred to as PTFE membrane); Non-woven films are most representative and competitive with ETFE films. The choice of membrane material is very high depending on the function of the building, fire protection requirements, design life and investment amount.

The second big Category: Inflatable class

Inflatable membrane structure architecture called air-bearing membrane structure building, sunshade it is a special building membrane (PVDF membrane) to do the building shell, equipped with a set of intelligent electromechanical equipment in a fully enclosed air-film building to provide pressure, so that the overall building inside always maintain positive pressure on the external environment, The structure system, which is supported by the internal and external pressure difference, is used in industrial plants, logistics warehouses, sports entertainment and military facilities, with super-large space, strong building flexibility, short installation cycle, low construction cost and maintenance cost, low energy consumption, environmental protection, super durability and weathering resistance, light weight and other characteristics. The service life can reach more than 35 years.
