Electrowelded grating, designed for the offshore industry, which incorporates intermediate rods between bearing serrated bars, to prevent the passage of larger objects of 15 millimetres and meet the specifications of the Norwegian Petroleum Directorate.
A elctrowelded or electroforged grating Offshore, consist of half moon serrated bearing bars, transversal rods and intermediate bars joined by welding, without adding welding material, and by pressure concentrated on the joints, guaranteeing the joint at each intersection and the uniformity of the grating.
Various qualities of hot rolled carbon steel, is the most common material used in the manufacture of
electrowelded grating. The stresses to which it would be subjected determine the quality and finish, with the most recommended being galvanized, which provides the essential protection against corrosion. The stainless steel is another material in which can be used to make electrowelded steel gratings.
The pictures shown are type details whose measurements are set out in the Product Manufacturing Table.
