The appearance of FRP grille has brought great convenience to people. Its characteristics of strong corrosion resistance, anti-magnetic insulation, natural anti-theft, weather resistance, load-bearing, portability, good manufacturability, and easy cutting can fully supplement the shortcomings and deficiencies of steel grating. Therefore, FRP grating has many obvious advantages, which can meet environmental requirements and gradually replace steel grating to maximize its role. Which is better, galvanized steel grating or FRP grating?
1. Weight:
FRP grating is lighter; steel grating is heavier. Polyester FRP grating is widely used in various industries because of its much lighter weight than steel grating. For example, the polyester fiberglass grille used in the car wash room is loved by many car wash workers because of its light weight. Compared with steel grating, the density of FRP grating is only 1/4 of steel and 2/3 of aluminum, while the strength is 10 times that of rigid PVC, and its absolute strength exceeds that of aluminum, reaching the level of ordinary steel.
Its light weight can greatly reduce the foundation support and reduce the cost of engineering materials.
2. Cost:
The cost of polyester fiberglass grating is higher; steel grating is cheaper. Since FRP grating is made of resin and fiberglass, the cost is slightly higher than that of ordinary steel grating, and customers should carefully consider it according to the actual situation when choosing.
3. Installation cost:
Polyester FRP grating saves a lot over galvanized steel grating. Although the cost of polyester fiberglass reinforced plastic lattice is high, it is easy to cut and install, no need for hot work and large lifting equipment, only a small amount of manpower and power tools, which greatly reduces the installation cost.
4. Maintenance cost:
Polyester FRP grating is almost maintenance-free and has a long service life; galvanized steel grating is maintenance-free and can be used for a long time.
5. Corrosion resistance:
The corrosion resistance of polyester fiberglass grating is very good; the corrosion resistance of galvanized steel grating is average, but there is no aging problem. FRP forming grating is resistant to various gas and liquid media such as acid, alkali, organic solvent, salt, etc., and has unparalleled advantages in the field of anti-corrosion. Unlike traditional metal gratings, it will not rust due to electrochemical corrosion under the action of chemical media, will not damage the structure of the material, and does not require regular or irregular inspection and maintenance.
Advantages and disadvantages of both
The weight of FRP grating is one third of that of galvanized sheet. The corrosion resistance is better, the load bearing is twice that of wood; the thermal insulation is good, the appearance is more beautiful than steel grating, the color of FRP can be various, such as yellow/green/light gray/dark gray. Relatively speaking, it is not as heavy as galvanized steel grating and has a long service life. Fiberglass grating is not suitable for outdoor use. If exposed to the sun and rain, it is easy to age under ultraviolet radiation, and has no recycling value and odor.
Galvanized steel grating has higher bearing capacity than FRP grating and has a longer service life than FRP grating. The surface of steel grating is generally treated with hot-dip galvanizing, which has better corrosion resistance. It belongs to the category of circular economy and can be recycled. Easy installation and many ways. The disadvantage is that the weight is heavy, the appearance is not as good as the glass fiber reinforced plastic grille, and it cannot be insulated. Abstract FRP grating can not completely replace steel grating, but it makes up for the conditions or fields that steel grating cannot meet. It fully relieves the powerless burden of steel grating and provides people with another way to solve the problem.
