Industrial Serrated or Treads Welded Steel Bar Grating
Steel Grating consists of a series of bearing bars welded (or
otherwise joined) at various intervals to perpendicular cross bars
to form a load-bearing panel. Panels are manufactured by welding,
locked by swaging, or press-locked processes.
Steel Grating can meet almost any load bearing or weight
requirement and is the most durable grating for rugged
applications. Bar grating is a top choice for strength, safety, and
long-term cost.
Features:
The steel grating has the characteristics of beautiful appearance,
optimal drainage, strong rust resistance,
maintenance-free and replacement, anti-theft, investment saving,
high strength: many specifications.
Products details:
1) indicates the treatment method: hot-dip galvanizing,
cold-galvanizing, spray painting.
(2) Distance between the flat steel and the flat steel: the center
distance between two adjacent flat steels, usually 30MM and 40MM.
(3) Crossbar spacing: The center spacing of two adjacent rails is
usually 50MM, 100, two, and other specifications can be customized.
(4) Bearing flat steel: usually 20X3, 25X3, 30X3, 32X3, 32X5, 40X4,
50X5 and other models.
