Industrial Serrated or Treads Welded Steel Bar Grating
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.
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.
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.
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.
