On the whole, the irregular classification of FRP gratings can be divided into four types. The most important thing is to classify them according to the purpose of the product and its own characteristics, giving many users more choices.
According to the irregularly classified series of FRP gratings that are often used, the FRP grating series can be roughly divided into several categories:
1. FRP grille cover
The so-called anti-slip performance can be better performed on the FRP grille cover, such as the sand cover grille, the striped cover grille and so on.
The surface of the FRP grille cover can be smooth, non-slip sanding or non-slip surface. The thickness of the grille cover is generally 4.0cm, and it can also be produced according to the customer's scale. The cover grille is often used in airtight applications. The area is used for sewage treatment facilities, which can prevent corrosion and prevent gas from overflowing. The cover grille of the non-slip surface can also be used as a ramp, manhole cover.
2. Conductive FRP grating
The FRP grating itself is an insulator, which is not conductive or thermally conductive. However, in some detailed occasions, the FRP grating also has electrical conductivity requirements. The detailed operation method is to add a graphite layer with a thickness of about 3~5mm on the surface to eliminate the danger of electrostatic charge. The conductive grille is also the same as the traditional glass fiber reinforced plastic grille, which has the characteristics of corrosion resistance, flame retardant, impact resistance, anti-skid, and light weight. It is suitable for oil refineries, ordnance factories, high-tech industries, computer rooms, chemical fiber plants, dry areas and Underground mining operations and other categories.
3. Microporous FRP grating
The planned walkway of the microporous FRP grating is cheaper and more cost-effective than aluminum grating and steel grating. The microporous fiberglass grille is especially suitable for walking on trolleys and wheelchairs. The double-layer microporous grille can prevent gadgets and other items from falling on the outside of the grille. The microporous grid is satisfied with the test of the 15mm diameter ball, suitable for coastal platforms, semiconductor and communication areas, and computer rooms.
Four, flat glass fiber reinforced plastic cover
The plane is made of glass fiber mesh cloth, glass fiber chopped strand mat and resin cured by manual hand lay-up. The surface of the plane can be smooth, non-slip paving surface and non-slip streaked surface. Under normal circumstances, the plane is used in combination with FRP, which is the so-called.
