Advantages of FRP Moulded Gratings VS Steel Gratings

FRP molded grating, also known as glass fiber reinforced plastic molded grating, has the following advantages over steel grating:

Strong corrosion resistance:

FRP molded grating is composed of glass fiber and resin. It has excellent corrosion resistance to many

gas and liquid media such as acid, alkali, organic solvents and salts. In corrosive environments such as

chemical, electroplating, and sewage treatment, there is no need to worry about rust and corrosion, and

the performance can be kept stable for a long time. Steel grating is generally made of carbon steel. Even

after anti-corrosion treatment such as hot-dip galvanizing, it may still rust when exposed to a strong

corrosive environment for a long time, affecting its service life.

Light weight and high strength:

The specific gravity of FRP molded grating is generally around 1.8, which is only 1/4 of steel, but its

strength is 10 times that of rigid polyvinyl chloride, and its absolute strength exceeds that of aluminum

and ordinary steel. This makes it more convenient during transportation and installation, which can greatly

reduce the foundation support, reduce the material cost and construction difficulty of the project. In contrast,

steel grating is heavy, and large-scale mechanical equipment is required for transportation and installation,

which increases the construction cost and difficulty.

Good electrical insulation:

FRP molded grating has excellent electrical insulation, no breakdown phenomenon under 10KV voltage,

and no electromagnetic properties. Therefore, it can be used for special occasions such as magnetically

sensitive equipment and live operations, such as electronics factories, substations, etc., which can effectively

avoid the risk of electric shock and electromagnetic interference. Steel grating is made of metal and is conductive.

When used in electrical environments, additional insulation measures are required.

Good fatigue resistance:

The fatigue resistance of FRP molded grating is about 50 times that of steel. Under long-term dynamic loads,

FRP molded grating is less likely to suffer damage such as fatigue cracks, and can maintain good performance.

It is suitable for frequent use and high-load places.
Good fire retardancy: The flame propagation rate of ordinary flame-retardant FRP molded grating does not exceed 25,

the flame propagation rate of advanced flame-retardant vinyl grating does not exceed 10, and the oxygen index is

not less than 28. In the event of a fire, it can delay the spread of flames, buy time for personnel evacuation and fire rescue,

and improve the safety of the place of use. Although the steel grating itself does not burn, it is easy to deform at high temperatures, which will affect the structural stability.

High design flexibility:

The size, color, shape, etc. of the FRP molded grating can be customized according to customer needs, which

can meet the requirements of different architectural styles and usage scenarios and has good decorative properties.

The structure and material formula of the grating can also be flexibly adjusted according to specific load-bearing and

usage requirements. The design flexibility of steel grating is relatively poor, and the appearance and size are usually relatively fixed.

Excellent anti-slip performance: FRP molded grating usually has a unique anti-slip texture design and high surface friction.

Even in wet and oily environments, it can effectively prevent people from slipping and reduce the occurrence of safety accidents.

In contrast, the anti-slip performance of the steel grating surface is relatively weak when it is wet or has impurities.

Long service life:

In theory, the service life of FRP molded grating can reach more than 20 years, and it can even be used longer

in some less corrosive environments. Due to its good corrosion resistance, fatigue resistance and other properties,

it is not easy to suffer serious damage and aging under normal use conditions. The service life of steel grating in general

environment is usually about 15 years, and the service life will be shorter in harsh environment.

Good environmental performance:

FRP molded grating can be recycled and reused, which meets the pursuit of sustainable development in modern

architecture, and has low pollution and energy consumption during production and use. Steel grating consumes a lot

of energy and resources during production, and the recycling and disposal after disposal is relatively complicated.
