Your choices for Gratings from NFT are almost endless. From “bar” style gratings and formed “plank” styles, as well as, gratings that are “molded” and “pultruded”, NFT has a solution for you. Gratings are available in an array of materials such as: steel, aluminum, fiberglass, powder-coated steel, stainless steel and galvanized steel. Our inventory offers you many options for your projects, and we are happy to handle custom orders as well.
When strength, safety and weight are paramount in addition to load bearing capabilities, open area, and easy fabrication, NFT Quality Grating is the product of choice. Gratings are typically used for all types of platforms, mezzanines, flooring, walkways, trenches, and more along with vertical applications such as partitions, fencing and infill panels.
Bar 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.
Bar 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. A typical panel configuration has bearing bars that are spaced 1-3/ 16 inches (center to center) with perpendicular cross bars spaced 4 inches apart (center to center). Other spacings are available to meet your loading and open area requirements.
Bar Grating is available in a wide selection of panel sizes; bar sizes and spacings; bar shapes; and material types. The most popular style is Welded Bar Grating.
Plank Grating is a one-piece construction product that allows easy field handling and cutting. The construction is formed and punched sheet metal or aluminum extrusion. The formed metal planks are available in galvanized, stainless, and plain steel and aluminum. These versatile planks come in a variety of heights and widths for almost every application.
Plank styles include a variety of channel configuration choices, some with interlocking choices, and walkway styles with integral toe plates. Plank choices include gratings with surface openings that are diamond-, rectangular-, slotted- or round-shaped, along with solid surfaces. Most plank gratings are lightweight and offer significantly higher slip resistance surfaces than bar grating styles.
For an economical solution for lighter traffic ramps, walkways, treads or other types of structural applications – consider Expanded Grating or Expanded Catwalk. The open diamond truss configuration is a much heavier gauge than regular expanded metal and provides sure footing. With Expanded “Grating”, the width of the sheet is parallel to the short way of the diamond opening, the length is parallel to the long way of the diamond opening. With Expanded “Catwalk”, the opposite is true – the short way of the diamond runs parallel to the length of the sheet (typically 10 foot) and the long way of the diamond/opening runs the short dimension of the sheet. Catwalk is structurally stronger because the long way of the diamond runs across the shorter supported span.
Expanded Grating is available in plain steel styles ranging from 3 to 6.25# per square foot; Catwalk Grating, 4.27# per square foot; Aluminum Expanded Grating, 2# per square foot.
