GFRC has been used for the past 30 years to produce many concrete products such as furniture, status and domes. In recent years, furniture made from GFRC has become increasingly popular worldwide. GFRC uses several methods in the production process, such as traditional hand-spray-up, hand molding and compression molding.The use of GFRC materials in handicrafts can also be a good way to show the uniqueness of their finished product, giving the designer wide freedom to create.
The way to manufacture precast GFRC elements is by hand spraying the GFRC into a die. With the direct spray-up method, a concentric chopper is required, which is fed by a spool of GFRC roving pulled into the chopper and blended at the nozzle. This mix has a higher fiber content (4 to 6%) than can be achieved with premix and is the recommended method for larger panels. It does, however, require experienced workers, expensive equipment and rigorous quality control.
The workmanship of hand-spray-up is unique, with fiberglass concrete injection prepared on the formwork, with a fine texture that ensures the product achieves superior compactness, strength and crack resistance. Its process is an international common production process and technology that is characterized by the long service life of the finished product produced, up to 50 years, almost as long as the life of the building.
GFRC is ideal for thin products such as flowerpots, countertops and trimming, and the resulting product is of better quality than common concrete coating techniques. Moreover, GFRC products can be easily molded into multiple shapes, have a strong sense of surface texture, and perform well in visual perception. Some GFRC crafts also incorporate features such as endemicity and cultural property, or incorporate multiple styles into their designs. The use of GFRC materials in handicrafts can also be a good way to show the uniqueness of their finished product, giving the designer wide freedom to create.
