The steel gate is mainly welded with steel plate as the base material. The steel gate is corrosion-resistant, and the rubber sealing ring can be used to seal the water. According to the increase of the water head, the gate can be equipped with grooved pulleys and positioning wheels to reduce frictional resistance and facilitate lifting. The bearing capacity of steel gates is much greater than that of cast iron gates.
Common anti-corrosion methods for steel gate include paint maintenance and metal spray maintenance. Before the protective treatment, the surface must be carefully derusted. Common methods include manual shoveling, wire brushing and sandblasting.
It is necessary to remove old paint and rust, rust spots, oil stains, dust, acid and alkali and salt residues from the steel gate, and then clean it once with nasal spray or turpentine.
