The European lines of GRC lines are convenient in modeling, light in weight and high in strength. However, more than 90% of GRC component lines in China are lightweight, but not strong enough. It is only necessary to lay 1~2 layers of mesh cloth on the mortar, add reinforcement, and then add mortar. They were powerless and collapsed within a few years. The internal reinforcement will rust and damage the mortar, which is especially dangerous when installed at heights.

The GRC industry chain is mainly composed of raw material suppliers, GRC product use consulting and effect designers, GRC product design and production vendors, GRC product installation and construction manufacturers, and end users with personalized GRC product needs as the end users. GRC industrial value chain is the structural form of value organization and creation behind the industrial chain. It represents the value attribute of the industrial chain and reflects the transfer and creation of value.

GRC lines are made of fast hardening sulphoaluminate low alkali cement and glass fiber. During the manufacturing process, the mortar ratio is 1:1 at a time, the coating thickness is uniform (up to 1cm), and the crack resistant glass fiber mesh cloth is paved.

The installation method of non bearing GRC Roman column is the same as pouring concrete from the upper opening after installation. The difference is that load-bearing GRC Roman columns should be installed first and then covered, otherwise concrete cannot be poured, while non load-bearing GRC Roman columns can be decorated with buildings first and then GRC Roman columns.
