This type of grating is most commonly used for service and industrial platforms.
The bearing bars placed edgeways are connected with tetrahedral, twisted cover rods, embedded with a force of 1000 kN and also welded at 2500 kVA.

Nowadays it’s very actual to use strong, available simple in use and high-quality materials as welded metal gratings. Metal gratings find application in those fields of industry where high reliability is necessary. Paving elements, bearing elements of designs and floors in industrial facilities can be rated as such objects. Welded metal gratings are made of steady strips of different sizes and special connecting cross bars which are joined with strips by means of contact welding.
Low-carbonaceous steel is used in production of metal gratings , such metals as stainless steel and aluminum can be also applied. Finished products are often covered with hot zinc. The main advantages of welded grating are almost complete elimination of misstatement in case of loading and a possibility of usage of long elements between supports. Welded metal gratings possess wear resistance, durability and nice-looking appearance. Thanks to these characteristics modern welded gratings are advantageous and attractive material for use in various range of application. Gratings are produced in any size.
