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

TG-01: Transformer grating has thick coating and bright surface for corrosion and rust resistance.

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.

 Steel bar grating has so many applications. The platform and walkway application is one of the most important applications.Platform and walkway grating is widely used in the factories, walking street, parking lot, port, warehouse and other places to form a flat and open operating platform or walkway. Sometimes, the platform and walkway grating can be used combined with stair tread gratings for further application.

The main types of platform and walkway grating are welded steel grating, swage-locked grating, press-locked grating, riveted grating and close mesh grating. Welded steel grating is the most commonly used type, it is suitable for all common applications. The swage-locked grating and press-locked grating supply excellent lateral stiffness of the grating. The riveted grating and close mesh grating are suitable for pedestrians who wearing high-heel shoes, roller skates and wheeled equipment passing through. To suit the shapes of ground and equipment, there maybe need irregular steel grating in some places.

 Steel bar grating is a widely used grating type. It can be used in the trench and drainage system as the trench and drainage cover to ensure the excellent drainage performance and secure the pedestrians safety.

Like most of steel gratings, such as welded steel grating and press-locked grating, the drainage trench grating is made of carbon steel, aluminum steel and stainless steel. Different materials of grating can suit different applications of customers. Carbon steel grating is the most economical grating among the three types and the aluminum grating features lightweight and corrosion resistance, it can be used in the corrosive environments. The stainless steel grating has unique chemical stability, it is the ideal products to be used in the acid or alkali environments and keep a long service life.

Drainage trench grating types

Angle frame can increase the load capacity of drainage trench grate.

Trench grate and angle frame

It is the simplest and most economical types of types of trench covers. It can be installed on the trench and drainage to form a cover. This cover can not only ensure the excellent drainage performance, but allow the traffic passing through. The galvanized angle frame gives the maximum opening and supplies a strong and solid base for the grating. It can bear the load of steel grating can improve the load carrying capacity of grating.

Except for the standard trench grate, there is a type of grate is made of close mesh steel grating. The close mesh steel grating is available for pedestrians wearing high-heel shoes, bicycles and other wheeled equipment easy passing through.

Angle sided grates

Angle sided grate is a type of drainage trench cover with angle bar on the two side of the grating. It is fit for the concrete trench, which is molded a channel to place the grates. The sided angle bars can bear the load capacity of the grating and ensure the long service life of the grate. The appropriate opening size can not only enable the drainage but also block the large wastes from entering the trench and blocking the trench.

The angle sided grate has smooth and serrated surface for choice. And the common length of angle sided grates are 1m.
