GNEE STEEL 19W4 steel grating is a welded bar grating with bearing bars at 19/16 in (30.2 mm) on centre and twisted cross bars at 4 in (101.6 mm) on centre, hot-dip galvanized after fabrication. This page gives the numbers specifiers ask for most: bar sizes, weight, open area, stiffness and span. 1. ...

11-W-4, 15-W-4 and 19-W-4 are all welded bar grating panels with cross bars at 4 in. (100 mm) on centre. The only difference is how far apart the bearing bars sit: 11/16 in. (17.5 mm), 15/16 in. (24 mm) and 1-3/16 in. (30 mm) respectively. That one number decides open area, self-weight, how many ...

11-W-4 steel grating is a welded close-mesh panel with bearing bars at 11/16 in. (17.5 mm) on centre and cross bars at 4 in. (100 mm) on centre. Most orders are not shipped as full standard panels: they are cut to a layout drawing, banded on the cut ends, drilled or notched around steelwork, and ...

Q235B is the most widely used ordinary bon structural steel in China, defined by the national standard GB/T 700. When it is roll-formed into bearing bars and cross bars and welded or press-locked into panels, it becomes Q235B steel grating — the workhorse flooring material of industrial platforms, ...

Q235B steel grating is an open-grid flooring panel made from Q235B bon structural steel to GB/T 700, in which evenly spaced bearing bars (the main load-rying members) are joined by cross bars through pressure welding, press-locking or riveting. Because the material ries a guaranteed yield strength ...

In industrial buildings, flooring is not just a surface—it directly affects: Load-bearing performanceFire safety complianceInstallation efficiencyTraditional concrete floors add weight, block airflow, and reduce flexibility during installation or modification. Metal floor grating offers a different ...

Platform steel grating is a structural-grade open flooring system engineered for industrial platforms, elevated walkways, and load-bearing access structures. Unlike standard grating used purely as floor covering, this product functions as a mechanically integrated platform component, designed to ...

The steel grating made from ASTM A36 bon steel is popularly used for operating gangway, walkways, and industrial flooring due to its high strength and load-bearing capabilities. ASTM A36 is a U.S. standard specification set by ASTM International for a standard-grade structural bon steel. It is one ...

Hot dipped galvanized steel grating is the preferred solution for industrial flooring systems exposed to moisture, chemicals, and aggressive outdoor environments. It is widely used in infrastructure, marine platforms, and processing facilities where long-term corrosion resistance is critical. As a ...
