Introduction to knowledge related to fiberglass grilles?
Lightweight: Its specific gravity is around 1.8, and its weight is only 1/4 of that of steel and 2/3 of that of aluminum;
Its strength is ten times that of rigid polyvinyl chloride, and its absolute strength greatly exceeds that of aluminum, reaching the level of ordinary steel;
● Corrosion resistance: It is non rust, non mold, non corrosive, does not require paint, and can withstand the corrosion of many gas and liquid media;
● Fatigue resistance: FRP grilles have some elasticity, which makes people who work on them feel comfortable for a long time. As a work platform, they reduce the tension on the legs and back of workers, increase work comfort, and thus improve work efficiency, which has been recommended by human engineers;
● Good comprehensive economic benefits: Compared with ordinary carbon steel, FRP grating has a lower comprehensive cost. Although its one-time investment is higher than ordinary carbon steel, due to its long service life, it can generally be used for 20 years without maintenance, so its comprehensive economic benefits are greatly better than using carbon steel;
Convenient installation: The use of FRP grids greatly reduces the weight of components, thereby reducing the weight of supporting structures. During installation, lifting equipment is not required, which is both economical and convenient.
● Safety: During the installation and use of FRP grilles, there will be no electric sparks generated due to collisions, especially suitable for use in flammable and explosive environments. In addition, grilles with anti slip surface layers can prevent slipping and reduce accidents;
According to different forming processes, fiberglass gratings can be divided into extruded fiberglass gratings and molded fiberglass gratings.
● Load bearing profiles: mainly composed of extruded "I" profiles or "T" profiles
It is used to connect load-bearing profiles, mainly using various round or irregular rods formed by extrusion
Spacing profile: Its function is to adjust and fix the porosity of the fiberglass grating, mainly using extruded bars
Use extruded "I" or "T" profiles as load-bearing rods, and various round or irregular rods formed by extrusion as connecting rods (connecting rods). Use adhesive to fix and connect the horizontal rods and load-bearing rods at a certain distance to form FRP grids.
Molded FRP grille: Simultaneously lay glass fiber untwisted roving on a large metal mold, cast thermosetting resin, and then cold cure in one go to form a molded FRP grille after demolding. As needed, the upper surface of the molded grille can be sealed with fiberglass steel plates during production, forming a structure where the lower layer is the grille and the upper layer is a flat plate.
