Grating panels are typically identified using standardized model codes that convey their specifications, facilitating design selection, production management, and on-site installation. Generally, the identification includes key information such as the dimensions of the bearing bars (flat steel), spacing, load-bearing type, and surface treatment.
A common identification format is "Bearing Bar Height × Thickness / Bearing Bar Spacing × Cross Bar Spacing." For instance, in the model "G325/30/100," "32×5" indicates the height and thickness of the bearing bar, "30" represents the center-to-center spacing of the bearing bars, and "100" represents the spacing of the cross bars. This notation provides a clear indication of the grating's structural strength and scope of application.
Some engineering or manufacturer standards append letters or codes to the model to denote surface treatments or special properties. For example, "G" in "G325/30/100 G" typically signifies hot-dip galvanizing, while "S" might indicate stainless steel and "P" might indicate a painted finish; although specific conventions vary by company, the underlying logic remains consistent.
In engineering drawings or procurement lists, grating identification is often supplemented with dimensions (such as length and width), load-bearing ratings, and installation location details to ensure precise alignment between production and on-site installation, thereby preventing specification errors.
