Steel Grating Resources
Clear terminology and traceable data help buyers, fabricators and project teams discuss the same requirement.
Specifications and Standard Sizes
A grating specification is a short list of numbers: bearing-bar size, pitch, cross-bar pitch, panel dimensions and…
How to Maintain and Inspect Trench Grating
Trench grating usually fails slowly: coating damage, a loose fixing, a seat that wears. A short regular inspection…
Grating for Corrosive Drainage Environments
Drainage is often more aggressive than it looks: standing liquid, salts, cleaning chemicals and repeated wet-dry…
Information Needed for a Trench Grating Quote
A trench grating quote is only as good as the information behind it. Send the opening, the span and bearing…
Trench Drain Grate Load Classes Explained
A load class is a shorthand for the traffic a grate is built to carry. Matching the class to the location prevents…
Galvanized vs Stainless Steel Grating
Galvanized grating is carbon steel protected by a zinc coating. Stainless grating resists corrosion through its alloy…
How to Calculate Steel Grating Weight
Grating weight is the sum of its parts: the bearing bars, the cross bars, the banding and any coating. Knowing it…
How to Calculate Steel Grating Load Capacity
Grating capacity is not a single number—it depends on the bar size, the pitch, the clear span and how the panel is…
How to Read a Steel Grating Load Table
A load table tells you how much a given grating panel carries over a given span. Reading it correctly means knowing…
How to Install Framed Trench Grating
With framed trench grating the frame is installed first and the cover follows. Get the frame level, anchored and…
How to Install Trench Drain Grating
Installing trench drain grating is mostly preparation: a clean, level, well-supported seating. Fit the panels to that…
How to Measure a Trench Drain Grate
A grate that fits is mostly a measuring problem. Get the clear opening, the seating width, the depth and the bearing…
How to Choose Trench Drain Grates
Choosing a trench drain grate is mostly about three inputs: the opening you have, the load that will cross it, and…
What Is Hot-Dip Galvanized Steel Grating?
Hot-dip galvanized steel grating is finished steel grating that has been immersed in molten zinc, forming a coating…
What Is Trench Drain Grating?
Trench drain grating is the open metal grate that covers a linear drainage trench. It lets surface water into the…
How to Choose Bearing Bar Size and Spacing
Bearing-bar size and pitch are the two numbers that decide how much a grating panel carries and how big the openings…
Welded vs Press-Locked Steel Grating
Both are steel bar gratings with the same open grid, but the way the cross bars join the bearing bars changes…
Plain vs Serrated Steel Grating
The only difference between plain and serrated steel grating is the top edge of the bearing bars. Plain is flat…
What Is Steel Bar Grating?
Steel bar grating—often called steel grating or bar grating—is an open grid built from parallel bearing bars joined…
Hot-Dip Galvanizing After Fabrication
Hot-dip galvanizing protects steel grating by immersing the finished panel in molten zinc. Doing it after fabrication…
Trench Cover and Steel Grating FAQ
Find practical answers to the questions commonly asked when selecting, specifying and ordering trench cover grating…
Steel Grating Load Tables
A grating load calculation combines the bearing bar section, spacing, clear span, load type, units and deflection…
How to Specify Trench Cover Grating
The fastest route to a useful trench grating quotation is a dimensioned opening plus the actual traffic and support…
Steel Grating Specifications
A clear steel grating specification identifies what carries the load, how the panel is supported and what fabrication…
