Concealed manhole cover is used walkway.Metal Bar Grating is the workhorse of the industrial flooring market and has served industry for decades.Strong and durable with an exceptional strength-to-weight ratio, metal bar grating can be easily fabricated to nearly any configuration.The high percentage of open area makes bar grating practically maintenance-free and all products are fully recyclable.
Manufactured by assembling a series of equally spaced metal bars to connecting cross members, bar grating is available in three popular materials; mild carbon steel, 6000 series aluminum, and 300 series stainless steels. Additionally, Grating Pacific has the capacity to produce gratings constructed with other specialty metal alloys
A manhole cover is a removable plate forming the lid over the opening of a manhole, to prevent anyone fromfalling in and to keep unauthorized persons out
