EPS线条与GRC的比较主要三个不同点在于：材质、用途、特性这三方面，详细如下：

The three main differences between EPS and GRC are as follows: material, usage and characteristics.

材质区别：

Material difference:

GRC装饰构件主要以耐碱玻璃纤维为增强辅材，低碱度硫铝酸盐水泥为胶结材料，及黄沙或石英砂构成。

GRC decorative components are mainly composed of alkali-resistant glass fiber as reinforcement auxiliary material, low alkalinity sulphoaluminate cement as cementing material, and yellow sand or quartz sand.

EPS装饰构件是随外墙保温材料及GRC构件行业的退火炉发展延伸的一个新兴产品，主材以聚苯乙烯保温板为基础，应用电热丝切割设备对板材进行切割成各种线条。

EPS decorative component is a new product extending with the development of annealing furnace in the field of exterior wall thermal insulation material and GRC component. The main material is based on polystyrene thermal insulation board, which is cut into various lines by electric wire cutting equipment.

通过图片的比较。GRC和EPS二者的区别是很明显的，不管是在材料上还是用途上都有着较大的差异。

Compare the pictures. The difference between GRC and EPS is obvious. There are great differences in materials and applications.

用途区分：

Use distinction:

GRC：GRC装饰制品（欧式构件包括罗马柱、窗套、门楣等）、GRC外墙板（类似于幕墙板）、GRC隔墙板（室内隔墙）、雕塑、园林园艺制品等。

GRC: GRC decorations (European components include Roman columns, window covers, lintels, etc.), GRC exterior wall panels (similar to curtain wall panels), GRC partition panels (interior wall), sculptures, gardening products, etc.

EPS：在建筑中一般作为保温隔热材料，也可作为轻质填充材料使用。

EPS: It is generally used as thermal insulation material in buildings, but also as light filling material.

特性区分：

Characteristic distinction:

GRC：造型多样化、防火性能好、使用寿命长、强度高等特点。

GRC: Various shapes, good fire resistance, long service life, high strength and so on.

EPS：轻度高、成本低，生产周期快，抗冻保温等。

EPS: Mild high, low cost, fast production cycle, anti-freeze insulation, etc.

GRC与EPS两者都为建筑行业中的装饰材料，两者各有所长，也各有不足，一般在划线高质量的工程中，会优先选择GRC材料，毕竟在装饰上GRC的效果更胜一筹，且特性优良，在价钱上GRC也会稍贵一些。

GRC and EPS are both decorative materials in the construction industry. They have their own strengths and weaknesses. Generally, GRC materials are preferred in high-quality projects. After all, GRC is better in decoration and has excellent characteristics. GRC is also slightly more expensive in price.
