General Purpose Granite is a versatile and durable natural stone, known for its unique physical properties and striking patterns. Often referred to as the "king of rocks," it has been widely used in architecture for centuries. People often use a rating system—such as one, two, three, or four—to assess the quality of granite. From rooftops to flooring, granite can be found throughout buildings. It's also commonly crushed and used in cement production or as fill material in dams. Many structures that require resistance to weathering or long-term durability are made from granite. Notable examples include the sign at the Chiang Kai-shek Memorial Hall in Taipei and the Monument to the People's Heroes in front of Tiananmen Square in Beijing. The enduring nature of granite is proven by ancient structures like the Egyptian pyramids, which have withstood the test of time. Granite features a uniform structure, high hardness, and an attractive color palette. It is considered a premium building material, with compressive strength ranging between 1000 to 3000 kg/cm² depending on the type and origin. Its resistance to weathering ensures that it maintains its appearance for over a century. Due to its toughness and wear resistance, granite is a top choice for high-end architectural projects, including grand halls, public spaces, and outdoor sculptures. Commercial Use In the commercial market, granite includes not only true granite but also related rock types such as gneiss, granitic gneiss, granodiorite, and syenite. These rocks contain a mix of minerals, including quartz, feldspar, and mica. Commercial granite also encompasses other similar formations, such as feldspathic rocks with minor accessory minerals, often chosen for their aesthetic appeal. For example, plagioclase-rich rocks are popular among designers and architects for their visual impact. Gneiss is a coarse-grained metamorphic rock primarily composed of silicate minerals. It exhibits a banded or layered texture due to the arrangement of different mineral components. This structure gives it a distinct look and makes it suitable for both functional and decorative applications. According to the American Society for Testing Materials (ASTM) classification, granite is divided into two main categories: ordinary granite and black granite. Ordinary granite typically contains quartz, feldspar, and mica, and may appear in dark green or black hues due to the presence of colored minerals. The color is often influenced by the feldspar content. Black granite, on the other hand, consists mainly of plagioclase, pyroxene, olivine, and hornblende. It is further categorized into three subtypes: porphyry, diabase, and basalt, each with unique characteristics and uses. The hand carts and trollys are our new products.
