Introduction: standard is a sign of the level of industry development

Standard is a kind of open and transparent things, the standards, both producers and consumers, we on a commodity raw materials, quality, performance and so on are well aware, in fact, it makes commercial transactions "contract" became even more determined and make more explicit the rights and obligations of both parties.

Norms of enterprises have a common characteristic, always want to market open, transparent, standardized and healthy development; and speculators are always hope to muddy the waters, profiting from them.

China's GRC industry in the rapid development of the same time, should pay more attention to the quality of development. To create an orderly market competition environment by promoting the standardization of GRC industry. "Standard" is the basis of market order.

Through the standard optimization, to promote industrial upgrading, has been proved to be the only way for the development of industrial developed countries. In today's economic globalization and information technology, the status and function of the standard is becoming more and more important. Over the years, Britain, France, Germany and other Western European countries and the United States, has always attached great importance to standardization, rely on the technical strength and modern industrial base spare no effort to the standard of our country into the international standard. In recent years, the German standard chemistry (DIN) 80% or more of the workload is spent on the development of international standards and European standards.

Standards behind a huge economic interests, the international standards for the right to develop, will be more intense. At present our country government in the formulation of standards encourage use or make reference to international standards and foreign advanced standards, to promote our country standards with international standards, in order to improve the standard of our country, promote the economic development of the technology.

China's industry standards for GRC under the guidance of national policy guidance, formulate the standard of a series of GRC, has made great achievements, and played a very good role in promoting the healthy development of the GRC industry in China. As a result of the past planned economy system, the GRC design standard and the GRC construction installation standard are still in the blank state at present. Has become a prominent obstacle to the development of China's GRC industry. China GRC industry is a difficult in the rugged mountain road a lame.

"If I see a little farther than others, it is because I stand on the shoulders of giants.". "GRC European standard is such a giant GRC industry, we should use the GRC European standard system, quickly boarded a new height.

GRC advantage

1, infinite plasticity

GRC product is the raw material according to a certain proportion of mixing, in the mold casting molding, can produce a rich, textured products. According to the different needs of customers and designers, to carry out any artistic form, the perfect realization of the designer's dream.

2, the quality is light, the intensity is high

The bulk density of GRC is about 1.8-1.9,8mm, and the weight of the GRC is only 15kg, the compressive strength is over 40Mpa, the bending strength is over 34Mpa, which is much more than the international standard.

3, ultra-thin technology, size

GRC board is the most thin 5mm, the standard width of 900mm and 1200mm, the length is not limited to meet the transport conditions, can be made into 5mm to any thickness, arbitrary size. Because of the installation, the thickness of the lower the safety factor is lower by the gravity of the self. Since the 5.12 Wenchuan earthquake, the industry standard thickness can not be greater than 2.5cm.

4, rich in color, shape and variety

GRC products using homogeneous transmural mineral raw materials can be made into a variety of different colors and different shapes of artistic effect according to the needs of customers.

5, texture, texture and more

GRC products surface can be made of different sandblasted, litchi surface, so smooth texture effects, can also be made into a bar, engraving, relief and other different texture effects.

6, environmental protection, no radiation

GRC is a renewable material, is conducive to environmental protection. The raw materials contain no radioactive nuclear elements, and are a kind of environmental protection material for the national radioactive radionuclides.
