 G.R.C cornice

What is G.R.C?

G.R.C (Glassfibre Reinforced Concrete) – Alkali-resistant glass fiber reinforced concrete product, is a composite mixture that the world has used very popularly for many years, because it has many advantages compared to traditional concrete. system. G.R.C is encouraged by the G.R.C association to be used on a wide and flexible scale in many construction categories such as: architecture, building cladding products, flooring, landscaping, walls and windows, modular construction, Soundproofing and heat insulation for ceilings, walls, bridges, tunnels and many other utilities. Some countries refer to G.R.C as G.F.R.C.

How was G.R.C invented?

The B.R.E organization (Building Research Establishment) and the Piketon Brothers company in the UK began research and development of G.R.C materials in 1965. They concluded that fiberglass itself has very good alkali resistance when used. Use with ordinary Portland cement. The G.R.C industry was officially established in 1970 in the UK. Vinh Cuu is the first company in Vietnam to apply G.R.C to decorative concrete products and has exported to many countries around the world such as Japan, Australia, Chile, America,…

After many years of research and testing. Vinh Cuu Company has launched a line of fiber reinforced concrete products applied to many constructions and projects nationwide. G.R.C cornice products are diverse in size and design, especially G.R.C cornice products with large specifications such as 100 x 200 x 1.5 (cm) and 150 x 200 x 1.5 (cm), are produced with modern machinery and technology.

The product is applied in construction projects such as shopping centers, hotels, resorts, villas… creating simple yet sophisticated highlights, bringing elegance to each project.

Currently, there are many types of moldings in construction such as: plaster moldings, wooden moldings, plastic moldings and GRC moldings. In this article, we will learn about what moldings are, what GRC moldings are and why we should use GRC moldings.

What is a cornice?

Moldings (also known as wall wool) are materials that decorate the walls, columns, and ceilings of a building.

  • Molding: A strip of material with different cross-sections, used to create a transition effect between surfaces or for decoration.
  • Thread: A strip of material raised from the wall surface (embossed thread) or embedded in the plaster (recessed thread). The width of the thread is usually from 1.5 to 3cm, much smaller than the cornice. Only applied in accent positions on walls and ceilings for decoration.

What is a GRC cornice?

GRC cornices are a new construction material, produced by mold casting or machine injection from a mixture of fine aggregate concrete: cement, clean sand, clean water, alkali-resistant glass fiber and chemical additives. flexible. With molding technology, GRC cornices have diverse designs, sharp, delicate and uniform pattern details.

This helps GRC moldings outperform other types of moldings, which depend on the skill of the craftsman. Molded GRC cornices help create products with a finished surface with natural colors, suitable for modern architectural works. This is a multi-purpose material, produced identically to actual details, suitable to the requirements of each project, and is the ideal solution for construction projects that require meticulous decorative details.

Development of Molding Manufacturing Techniques

In the past, moldings were often covered with a mixture of cement mortar or plaster, or using plastic or wooden moldings. However, covering cornices with cement mortar or plaster is very time-consuming and depends on the skill of the worker. Plastic or wooden moldings have poor durability, are susceptible to fire, warping, termites and are not suitable for exterior decoration.

With the development of modern construction technology, GRC cornices were born, meeting construction requirements and overcoming the disadvantages of traditional cornices. Therefore, there is no reason for architects, contractors and investors not to choose GRC moldings. This is not only an economic calculation but also ensures the technical, architectural, structural, durability and aesthetic requirements for each project.

Compare GRC Moldings with Other Types of Moldings

Currently, on the market there are many types of moldings such as: plaster moldings, wooden moldings, PU moldings, PS moldings and GRC moldings. Each type of molding has its own price, advantages and disadvantages, so choosing the type of molding that suits the structure and architecture of the project is very important.
