1.Excellent fire performance
The melting point of stainless steel is around 1500 0 C. The stainless steel spacer can ensure the integrity of the glass structure under the condition of high temperature and high temperature. It is the best choice for fireproof windows and fireproof glass.
2.Outstanding warm edge performance
The thermal conductivity of stainless steel warm edge spacer is 14.3 w/m. K, which is less than 9 parts of aluminum spacer, so it is a warm edge spacer.
3.Reliable sealing structure
The linear expansion coefficient of stainless steel spacer is 15.7, which is the closest to the linear expansion coefficient of glass.According to the US Sealed Insulating Glass Association (SIGMA) for 15 years of tracking statistics on insulating glass, the industry average failure rate is more than 8%, while the 20-year failure rate of insulating glass with stainless steel warm-edged spacers is only 0.5%.
4.Stable chemical properties
As an inorganic material, stainless steel has stable chemical properties under the action of ultraviolet light and high temperature, no chemical volatilization, and does not react with the soft coating of off-line low-emissivity glass.
5.Superior mechanical properties
The stainless steel spacer can provide the rigidity and structural strength required for public building insulating glass. It can be used not only for residential doors and windows but also for structural curtain wall glass, large plate insulating glass, high-rise buildings and places with high wind loads.
