GRC equipment is designed for the efficient production and spraying of Glassfiber Reinforced Concrete. It is commonly used for GRC facade panels, architectural decorations, columns, sculptures, and other lightweight concrete elements. Compared with fully manual production, modern GRC equipment offers more stable material delivery, controlled fibre feeding, and easier operation. If you are looking for a reliable GRC machine for your workshop or construction project, YG can provide suitable equipment and OEM support based on your requirements. 【WhatsApp/WeChat/Skype/Phone】+86 159 3715 2330

GRC Machine Production Process: From Mixing to Spraying
A GRC machine is only one part of the complete production process. Good results also depend on material preparation, mixing, mould design, spraying technique, and curing.
Material Preparation
The first step is preparing the required cement, sand, water, admixtures, and glass fibre.
The material ratio should follow the requirements of the specific GRC product. A stable mix makes pumping and spraying easier.
Slurry Mixing
The cement-based slurry needs to be mixed until the materials are evenly distributed.
The slurry should have suitable workability for the selected pump and spray system. A mixture that is too dry or too thick can affect material delivery.
Fibre Feeding
Fibre is an important part of GRC production. The fibre feeding rate needs to remain stable during spraying.
The YG-GRC200 provides a fibre output of 500-800 g/min, while the YG-GRC300 provides 600-1000 g/min.
This controlled feeding helps operators maintain a more consistent production process.
GRC Spraying
After preparation, the slurry and fibre are delivered to the spray gun.
The operator sprays the material onto the mould or prepared surface layer by layer. The spraying technique may vary according to the product shape and required thickness.
For projects requiring a surface finishing layer, the YG-GRC300 can be configured with a concentric + facing coat gun.
Finishing and Curing
After spraying, the GRC component is normally leveled, finished, and cured according to the production requirements.
The final quality depends on more than the machine itself. Material formulation, operator experience, mould quality, spraying thickness, and curing conditions all matter.

GRC Equipment Applications in Modern Construction
GRC is widely used where designers want architectural detail without relying entirely on heavy traditional concrete components.
Facade panels are one common application. GRC can be shaped into different textures, curves, patterns, and decorative surfaces.
Architectural columns and decorative elements are another important use. These components often require repeatable shapes and controlled material application.
GRC equipment can also support customized production. For example, a workshop may produce different decorative panels for hotels, commercial buildings, public spaces, or residential projects.
The equipment is especially useful when the same production process needs to be repeated across multiple components.
For buyers, it is important to consider the complete application rather than purchasing a machine based only on its output figure.

YG GRC Machine for Overseas Projects
For international buyers, purchasing a machine involves more than checking the basic specifications.
YG supports overseas customers with OEM service and equipment configuration. Buyers can discuss their intended application, production requirements, workshop conditions, and machine configuration before ordering.
The two YG models also provide different combinations of output, hopper capacity, pump type, and spray gun configuration.
For example, a workshop producing smaller architectural components may prefer the more compact YG-GRC200. A production line with higher material requirements may consider the YG-GRC300.
It is also useful to confirm transportation space, installation conditions, local electrical requirements, spare parts, and technical support before shipment.【WhatsApp/WeChat/Skype/Phone】+86 159 3715 2330

GRC Equipment Buying Checklist
Before placing an order, overseas buyers can use this simple checklist:
| Check Before Ordering | What to Confirm |
| Production Output | Required slurry output |
| Fibre Feeding | Required fibre output |
| Pump | Suitable pump type |
| Hopper | Required working capacity |
| Power | 380V, 3-phase availability |
| Spray Gun | Standard or facing coat configuration |
| Machine Size | Workshop and transportation space |
| Control System | PLC + touchscreen requirements |
| OEM Support | Customization and technical requirements |
The best GRC equipment is not necessarily the largest machine.
A better approach is to match the machine with your production volume, material requirements, workshop space, and final product type.
