First of all, let's talk about raw materials. The main raw materials for glass fiber reinforced plastic (GFRP) grating are resin and glass fiber. The glass fiber is divided into two types: soda glass and alkali-free glass. The alkali-free glass is more expensive. Resin also has many types. The specific resin should be chosen according to the application environment. For example, in a chemical plant, a resin with good corrosion resistance should be chosen; in a boiler plant, a resin with excellent high temperature resistance should be chosen.
Then let's look at the standard and thickness of the glass fiber reinforced plastic (GFRP) grating. Generally, the length and width of molded gratings are 3.66m and 1.22m, which are fixed. The price difference mainly lies in the thickness of the grating. The thicker the grating, the stronger its load-bearing capacity will be.
There are also several surface types of glass fiber reinforced plastic (GFRP) gratings:
Normal type gratings: This type of grating has smooth upper and lower surfaces, which are mainly used in construction, decoration, machine walkways, fences, and walls. Its price is around 200 yuan per square meter.
Sand-covered gratings: This type of grating adds quartz sand to the upper surface of the GFRP grating. It is mainly used in environments with high slip resistance requirements, such as oil-polluted, sloping surfaces, or in damp, oily, or frozen environments. It has excellent anti-slip performance.
Groove standard gratings: This is an economical and versatile anti-slip standard grating. Its upper surface is an inner arcuate surface with a groove that provides good anti-slip performance. This type of grating has a wide range of applications, such as water treatment plants, residential areas, electroplating plants, sewage treatment plants, and chemical plants.
Microporous gratings: This double-layer microporous grating has a low open cell rate, which can reduce the risk of falling objects piercing through the grid holes at high altitudes. Therefore, it is ideal for use in areas such as high-altitude walkways to prevent heavy objects from falling. In addition, this type of grating has three available surfaces: groove type, sand-covered type, and smooth surface type.
