EPS lines and GRC lines are unclear? Let me tell you the difference now!

Because of the great similarity in appearance between EPS lines and GRC lines, many people are confused about which is the EPS line and which is the GRC line.
Although the two are very similar in appearance, they have completely different "connotations". Let's take a look at the differences between them.
 

Difference 1. The composition of the theme materials is different

GRC is made of alkali-resistant glass fiber as reinforcement, sulphoaluminate low-alkalinity cement as cement and mixed with appropriate base material to form the base material, and is made through production processes such as injection, vertical mold casting, extrusion, and flow slurry. A lightweight, high-strength, high-toughness, multi-functional new inorganic composite material.
 
 
GRC decorative components
EPS line is a new type of exterior wall decorative line and components. EPS decorative line is made of demoulding B2 grade fireproof polystyrene as the main body, pasted with alkali-resistant glass fiber mesh cloth, and compounded with a special bonding outer maintenance layer. become.

Difference 2. the weight is different

GRC material is a solid material, with cement as the main material, which is heavy and not suitable for high-rise buildings, and it is prone to falling off.
The aggregate of EPS lines is polystyrene, and its weight is about 1/6 of that of GRC decorative lines, so one person can move it at will. Even in high-rise buildings, construction is still convenient.

Difference 3. the production process is different

GRC line is a cement slurry pouring product. The product is made of cement binder and mixed with base material to form the base material, and is made by spraying, vertical mold casting, extrusion, flow slurry and other processes. The cost is high, the process is long, and mold opening is required. After the product is finalized, it cannot be modified and needs to be remade.
The EPS lines are designed and shaped by computer, automatically cut, no need to open the mold, low cost, and the on-site construction can still be cut after the product is finalized, the shape can be processed at will, and the product production period is short.

Difference4. the installation process is different

When installing GRC lines, it is difficult to carry at high altitude and the risk factor is high. Professional construction personnel are required for construction. The installation is fixed by anchor bolt welding.
It should be noted that in the reconstruction and decoration of old houses, if there is a lack of embedded parts GRC, it cannot be integrated with the exterior walls of old buildings, and cold and heat bridges may occur.

▲GRC stone imitation Roman column
EPS lines are easy to carry, and are bonded with adhesives, with high bonding strength; they can be cut, spliced, and pasted at will, with high installation efficiency, low cost, and safe and fast construction.
It can be used for the exterior decoration of old houses, and can achieve the effect of tailoring clothes and sewing on the spot. The product has low thermal conductivity and good heat preservation effect.

Difference 5. Different performance

GRC line products are heavy in quality and good in fire resistance, but GRC finished components do not have thermal insulation performance. GRC is waterproof and durable, with high strength and rich expressive power.
 
▲GRC line exterior wall decoration
EPS line products are light in weight, good in heat preservation effect, and firm in bonding. They meet the relevant national building energy-saving construction standards and are now widely used.

Difference 6. Different post-processing techniques

After the GRC line is installed, it needs to be puttyed, polished, and the corners need to be repaired, and the surface treatment needs to be done after waterproof coating.
▲ GRC lines decorate plaster statues
The EPS line does not need to be putty, it can be pasted directly for surface treatment.

Both of them have the characteristics of good safety and high cost performance after certain treatment. The overall shape is very high-end and atmospheric, and both can give people a certain visual impact.
