The steel grate is an open steel member that is orthogonally combined with load-bearing flat steel and cross bars according to a certain distance, and fixed by welding or pressing; the cross bars generally use twisted square steel, and round steel can also be used. or flat steel,
Steel grates are mainly used as gutter cover plates, steel structure platform plates, steel ladder treads, trench cover plates, steel ladder treads, building ceilings, etc.

The bimetal inside the previous bimetal thermometer was able to be disassembled with the slender conductive rod. The bimetal extracted from the protective sleeve was a black spiral as a result of a spring. There was a fine in the center of the spiral. The long stainless steel has good hardness. Like the conductive rod at the lower part of the pressure gauge pointer, its end is welded to one end of the bimetal. The other end of the bimetal is welded to the thin rod. When the bimetal is heated, the bimetal generates torsion. Thin rod rotation. The upper end of the thin rod is connected by a conductive copper spring, and the other end of the conductive spring is the pointer portion. The bi-metal torsional force of the thin rod is transmitted to the spring and the torsion of the spring is transmitted to the pointer. The dial is mounted on the lower part of the pointer, so the temperature correspondence can be displayed.
The current bimetal thermometer seals the lower part of the conductive spring into the protective sleeve and cannot be pulled out. The purpose is to be afraid of artificial changes in the torque. The position of the conductive spring is in the position where the protective sleeve is connected to the junction of the slip joint and the dial, the purpose being a soft connection transfer. In the use of the installation if the excessive force caused by the General Assembly of the spring soft connection part of the stress deformation, resulting in inaccurate instructions, so the installation should pay attention to the size of the intensity. The biggest error in the use of bimetals is the corresponding expansion deformation of the bimetal's heat conduction, and its long-term use will be inert, resulting in inaccurate indication.

Bimetal thermometer technological innovation
The bimetal thermometer has two pieces of metal with different expansion coefficients firmly bonded together. One end is fixed, and the other end is connected with a pointer through a transmission mechanism. When the temperature changes, due to different expansion coefficients, the bimetal generates an angular displacement, driving the pointer to indicate the corresponding temperature. This is the working principle of the bimetal thermometer. The bimetal thermometer has a simple structure, is inexpensive, easy to use, and resistant to vibrations. There is no "mercury damage" to a mercury thermometer. The scale is also relatively clear compared to a mercury thermometer, so it is widely used.
