Which is better, fiberglass grating or steel grating?

It is well known that when subjected to enough pressure, the plate will be deformed at light weight and broken at heavy weight. The fundamental way to improve the compression resistance of the plate is to replace the raw material. So what is the way to improve the crack resistance of the plate? Although the crack resistance does not significantly improve the overall bearing capacity of the plate, the safety is much higher. Let's see how high the crack resistance of fiberglass grating is.

Production and manufacture of fiberglass grating

Reasons for crack resistance of fiberglass grating plate:

Unlike wood and metal plates, GRP grating plates have strong toughness. When subjected to sufficiently high pressure, it will not break or deform. The toughness is strong, so the corresponding crack resistance is high. There are two main reasons:

1. Strong cohesion between raw material resin and glass fiber yarn

2. The crisscross of glass fiber yarn makes the mesh structure of glass fiber reinforced plastic grating more stable.

The density of fiberglass grating is very small because it is made of glass fiber and resin. Compared with steel grating, the weight of fiberglass grating of the same specification is only one quarter of that of steel grating. Although the density of fiberglass grating is small, its hardness is many times higher than that of polyethylene and aluminum.

The raw materials required for the fiberglass grating are made by melting the glass at high temperature, and resin is needed to assist in the production process, so the production cost of the fiberglass grating is higher than that of the steel grating. Although the production cost of the fiberglass grating is high, there is no need for maintenance after the installation of the fiberglass grating. Although the price of the steel grating is low, it will pay a lot of maintenance costs in the later stage.

Installation of fiberglass grating is much simpler than steel grating. Although the cost of fiberglass grating is high, the fiberglass grating has light weight and good elasticity, so it can be cut at will during the installation process without using lifting equipment, only a small amount of labor and cutting tools.

The fiberglass grating is made of non-metallic materials, so the corrosion resistance of the fiberglass grating is very good. The fiberglass grating will not rust due to electrochemical corrosion in chemical media, and will not damage the material structure.

The steel grating is welded with steel, and is generally used for the load-bearing of large equipment, so the steel grating has a stronger load-bearing capacity than the fiberglass grating.
