Aluminum grating products are light in weight, resistant to atmospheric corrosion, non-sparking and offer an attractive appearance. These characteristics make aluminum grating especially suitable for water and sewage treatment facilities, marine environments, food processing, and petrochemical installations. Manufactured from 6061 and 6063 alloys, the most popular and economical method of assembly for aluminum gratings is pressure locking by the swaging process. This versatile manufacturing system allows us to offer three distinct profiles: Standard Rectangular Bar, Flush-Top Rectangular Bar, and I-bar. Each profile is illustrated below.

To specify Indiana Gratings Swaged Aluminum Grating, the type of grating is indicated by designating one of the three profiles shown combined with the bearing bar/cross bar spacings illustrated in the table. Following selection of the type of grating, consult the load table below to select the appropriate bearing bar size for the loads and spans to be served.

Aluminum Plank Grating 

Aluminum Plank Grating produced in 6"wide modular planks, in lengths up to 26'-0", is a aversatile alternative to bar grating. Manufactured by extruding 6063 aluminum with integral I-beams and a fluted, skid resistant walking surface, plank grating provides a lightweight flooring with exceptional durability. Corrosion resistant, non-sparking, non-rusting and virtually maintenance free, Aluminum Plank Grating is commonly used in sewage and water treatment plants for walkways and platforms. Punched plank products offer excellent air circulation desirable for refrigeration floors and ceilings, as well as marine cargo holding systems. Available with plain or interlocking sides, these modular planks are easily fabricated into custom component panels with the simple addition of end banding. For enhanced skid resistance on the walking surface, specify plank with upset punched square or rectangular patterns.
