Product Details
FRP grating with leaf-shape cover, connected by a fiberglass chopped strand mat and fiberglass pultrusion dense grid integrally molded of curing, the cover grating surface may be glossy, slip sanding slip tread surface and the surface, the thickness of the cover grille is typically 3mm thick, also be based on the size of the production, is often used in the region of the cover grille closed requirements for sewage treatment facilities, can control odor and corrosion anti, FRP gratings cover slip surface may be used as the ramp, manhole cover, trench cover. FRP cover when mounting the available head screws coupled to the support member is fixed.
FRP cover advantages:
● Light weight fiberglass cover: its specific gravity is about 1.8, its weight is only 1/4 of steel, aluminum is 2/3;
● High strength fiberglass cover: which is ten times the strength of a hard polyethylene, the strength much higher than aluminum, to the level of ordinary steel;
● Corrosion resistant fiberglass cover: stainless it, mildew, rot does not, without paint, the ability of many gas, corrosive liquid medium;
● FRP cover of: FRP grating have some flexibility, which makes people long-term work on it felt comfortable, as a working platform, reducing the tension leg and back staff, thereby improving work efficiency, human engineering scientists recommend;
● Good FRP cover the overall economic efficiency: Compared with ordinary carbon steel, low-cost integrated FRP grating, although its one-time investment is higher than ordinary carbon steel, because of its long life, generally use two decades, and maintenance-free , and thus its overall economic efficiency is much better than carbon steel;
● Fiberglass cover to facilitate installation: using FRP grating member such that less weight, thus reducing the weight of the support structure, the installation does not require lifting equipment, both saving and convenient.
● FRP plate: the process is not generated in the installation and use of FRP grating spark due to collision, particularly suitable for use in an explosive environment, in addition, the grid having a non-slip surface layer is prevented from slipping and reduce accidents.
