Product Material:
Class A
Class A is best,with glass fiber fabric as the base material coated with PVC
(Permanent film material.)
Class B
Class B is better, with glass fiber fabric as base material coated with PVC
Class C
Class C is the most common in the three category,with polyester fabric as the base material coated with PVC . According to the coating material,there is a polymer.
Tetrafluoroethylene (PTFE), polyinglidenne fluoride (PVDF), polyvinhlidene fluoride(PVF), polyviny chloride(PVC), polyAmmonia ester(PU),rubber,etc,its life varies with different surface coating,usually up to 12-50 years.
Advantage of Marerial:
1. PVDF or titanium dioxide coated,the membrane material has good thermal insulation , it can reflect 70% solar heat. 17% heat is absorpted by the material itself,and 13% heat is transferred,while light transmittance is above 20%. The brightness keep 70% even after 10 years direct sun shining.
2. Covering large span
The membrane material is about one kg per square meter.Because of its light weight and the usage of high - strength material steel cable and steel structure,as well as the simple and reasonable stress system(the stress transferrmitted by axial force).The membrane structure is suitable forlarge span structure and provides wide space without pillar.
3. Fire resistance and shock resistance
The membrane material can meet requirements of fire resistance because itself is fire resistant,and it is shock resistance since the material is lightweight,flexible structure and with greater deformability.
4. Fast Set Up
The membrane structure material cutting,forming and skeleton,steel structure,and steel cable are made in factory,on - site is just assembly. The set up is very simple . so it is much faster than traditional construction.

Introduction of Membrane structure
1. Lightweight :The reason why the tensile strength of the membrane material is low in weight is that is relies on press tressing rather than material to maintain the stability of the structure.
2. Light transmission: Light transmission is one of the most widely recognized characteristics of modern membrane structure.With light transmission,the film roofing is still shine and light - transmitting to the naked eye even with a special transmission of only a few percent, thus it give the impression of a light roofing.
3. Flexibility:The tensioned membrane structure is not rigid and will deform under wing or snow loads.
4. Safety:The light tensioned membrane structure designed according to the existing national codes and guidelines has sufficient safety.The lightweight structure can maintain good stability under the horizontal load such as earthquake.
5. Function: Due to its own characteristics of the tensioned membrane structure,it can meet many different architectural functional requirements from simple sunshading to complex buildings with great form performance and is the most suitable for some functional requirements.
6. Weather resistant: An important role of membrane roofs is to the effect of various weather changes ( such as sun,rain,wind and snow) on the interior space and to maintain the comfort of the building indoor.
7. Extensibilityand adaptability :The extensible structure can be thought of as a man-made adaptive system that,like many natural organisms, can change its form as needed.
