When you start a transformer project, you may need the transformer grating in advance. Then you raise the transformer on the grating and lay the cobblestone on the grating. The stones are very important for absorbing the oil leaked by the transformer. Additional, the stones are insulated to the electricity and can protect the safe of worker and inspectors. The grating under the cobblestone and above the transformer is also important. It can supply high load capacity to load the heavy transformer and it will supply excellent heat dissipation performance to maintain the normal working and safe of transformer. Here are two types of transformer grating, just refer to them and choose the perfect one.
Hot dipped galvanized steel bar grating is composed of mild steel square pipe and rebar. The rebars are welded onto square pipe to form a rigid and solid structure. The steel bar grating panel will be hot dipped galvanized for rust and corrosion resistance. This type steel bar grating can supply high stability and loading capacity. Besides, the hot dipped galvanized coating can extend service life of grating and serve for the transformer bay for a long time.
Pultruded FRP grating, also called pultruded fiberglass grating. It is made of various colors fiberglass I bars and round cross bar. The cross bars are pultruded into bearing bars to form a corrosive resistant and lightweight structure. Compared with molded fiberglass grating, the pultruded fiberglass grating has a higher load capacity than Molded Fiberglass Grating but the weight is lighter than that. Pultruded FRP grating comes in a variety of resins and colors and are available with or without a slip resistant gritted surface.
