The spider system glass curtain wall is composed of glass panels, point support devices and supporting structures. The development and application of spider system glass curtain wall has shown strong vitality from the beginning. It provides a new design space for architects, which will undoubtedly promote the development and extension of building curtain wall. The main reason is that it has the stability of steel structure, the lightness of glass and the precision of machinery.

Advantages:

1. Good permeability: The glass panel is only connected to the support structure through a few points, with almost no obstruction, the best sight through the glass is achieved, the field of vision is maximized, and the transparency of the glass is applied to the limit.
2. Good flexibility: In the design of metal fasteners and metal connectors, in order to reduce and eliminate the stress concentration on the edge of the glass plate hole, the glass plate and the connector are in a hinged state, so that each connection point on the glass plate is in a hinged state. They can be rotated freely, and a little translation is also allowed to compensate for errors in installation and construction. Therefore, the glass of point-supported glass curtain walls generally does not generate installation stress, and can adapt to the deformation of the supporting structure after the load is applied. , so that the glass does not produce excessive stress concentration. At the same time, the use of point-supported glass curtain wall technology can meet the needs of architectural modeling to the greatest extent.
3. Good safety: Since the glass used in the point-supported glass curtain wall is all toughened, it is a safety glass, and metal fasteners and metal connectors are used to connect with the supporting structure, and the weather-resistant sealant only plays a sealing role and does not bear the load. , even if the glass is accidentally damaged, the tempered glass is broken into pieces, forming the so-called “glass rain”, there will be no serious injury accident of the whole glass falling.
4. Good sense of craftsmanship: The supporting structure of point-supported glass curtain wall has various forms. The supporting components are finely processed and the surface is smooth, which has a good sense of craftsmanship and art. Therefore, many architects like to use them.
5. Good environmental protection and energy saving: One of the characteristics of point-supported glass curtain wall is good permeability. Therefore, in the use of glass, white glass, ultra-clear glass and low-emissivity glass without light pollution should be selected, especially the insulating glass. Use, the energy saving effect is more obvious.

Features:

• Engineers and modern architects have designed this system with a main objective of getting the most possible transparency and thus the clearest vision which is normally hindered by using the various constructing elements. 
• The spider system offers practical solutions to glass assembly that no other system can provide. 
• To fix the glass up at the edges of the facade, one or two arms-accessories can be used.  In special applications, the number of arms might be more than two and the sheet of glass can be fixed by one arm at each corner. 
• The used accessories can be mounted against metal frames or against glass fins and tension rods are used to pull these accessories together. 
• Single, Insulating and laminated glass can be used with the spider system.  The thickness of the glass depends on the specifications of the project; therefore a special study is performed for each project. 
• When the spider system is chosen, halls will be applied to glass before being assembled. Therefore, tempered glass should be used.
