Introduction to Membrane Materials:
(1) PTFE Membrane Material: Composed of a polytetrafluoroethylene (PTFE) coating and a glass fiber base layer. PTFE membrane materials are of superior quality but come at a higher price.

(2) PVC Membrane Material: Composed of a polyvinyl chloride (PVC) coating and a polyester fiber base layer. It is widely used and moderately priced. (Chengdu Oupu Membrane Structure Landscape Engineering Co., Ltd. offers arch roof, metal roof, membrane structure steel structure series)
(3) PVC Membrane Material with Surface Layer: A surface coating of polyvinylidene fluoride or polyfluoride is applied on the PVC membrane material. This enhances performance compared to pure PVC membrane material, as offered by Wuhan Membrane Structure Company, with prices slightly higher than pure PVC materials.

Mechanical Properties:
(Membrane Structure Series from Chengdu Oupu Membrane Structure Landscape Engineering Co., Ltd.)
Medium-strength PVC Membrane: Only 0.61mm thick, yet its tensile strength is equivalent to half that of steel.
Medium-strength PTFE Membrane: Only 0.8mm thick, but its tensile strength matches that of steel.
The elastic modulus of membrane materials is low, which facilitates the formation of complex curved shapes.
Advantages of Membrane Structures, Fuyang Tensioned Membrane!
> Self-cleaning - Maintains pristine beauty throughout
PTFE membrane material has a surface coating made of polytetrafluoroethylene resin, similar to the non-stick coating on our everyday cookware. Its main feature is its extremely high non-adhesive property, which can be experienced while using a non-stick pan. The surface of PTFE membrane material does not easily adhere to dirt and dust, and its surface dust can be naturally washed away by rainwater, thus maintaining a clean appearance and indoor aesthetics even after long-term use.
> Light transmission - Bright spaces filled with natural light
During the day, sunlight passing through the membrane fills the building with natural diffused light. At night, indoor lights shining through the membrane add dreamlike night scenery to the space. When used for sports facilities and entertainment venues, membrane structures create an ideal commercial space combining comfort and functionality around the clock.
> Large Span - Column-free large spaces
In membrane structure buildings, the membrane material used is very light, weighing only about 1 kilogram per square meter. Therefore, membrane structures can fundamentally overcome the difficulties encountered by traditional structures in column-free large-span buildings, creating vast column-free spaces.
> Lightweight Structure - Strong disaster resistance and relief capabilities
Compared to other building materials, membrane materials are much lighter. Buildings with roofs made of membrane materials have excellent earthquake resistance and safety. Moreover, during disasters, multi-functional facilities and stadiums with membrane structures can be used as temporary shelters, emergency centers, and disaster command headquarters due to their column-free and bright large spaces. Thus, during emergencies, membrane structures can protect people's safety.
> Comfortable Space - Free-form designs with multiple uses
Membrane structures represent the most representative and promising architectural form of the 21st century. They break away from previous architectural forms, offering unique, novel, and diverse shapes and beautiful curves, becoming iconic city architecture. Membrane structures provide various uses, including sports facilities, transportation facilities, commercial facilities, public facilities, and charming and personalized landscape elements and landmark works, giving architects and planners greater imagination and creative space.
> Snow Management - Beneficial for snowy regions
In snowy areas, managing snowfall to prevent damage to buildings requires significant human and financial resources. Reducing these costs is a challenge for technical personnel. Membrane roof surfaces are less likely to accumulate snow compared to other roofing materials. Even with a small incline angle, snow will slide off automatically. Furthermore, due to the lower thermal conductivity of PTFE membrane materials, if snow-melting equipment is used, detailed snow-melting operations can be performed, maximizing the efficiency of heating devices, allowing for smaller roof slopes.
> Fire Resistance and Durability - Ideal architectural membrane materials
Membrane structures using PTFE membrane materials possess heat resistance, climate resistance, drug resistance, high strength, and fireproof characteristics. They do not age easily and maintain their initial strength even after long-term use. Membrane structures are divided into permanent membrane structures (with a lifespan exceeding 25 years) and semi-permanent membrane structures (with a lifespan of 10-15 years).
