Grating for Industrial Platforms — Walkways & Mezzanines

Grating for Industrial Platforms & Walkways

Elevated platforms are where bar grating earns its keep. On a mezzanine or catwalk, solid plate traps spills, blocks light to the level below, and adds dead load the structure has to carry. Open-grid welded steel grating solves all three: typical panels are more than 70% open area, so air, light, and washdown water pass straight through while the walking surface stays drained and visible from underneath.

GoGrating fabricates platform grating to order from Anping, Hebei — the wire-mesh and grating capital that produces over 70% of China's output, with 800+ fabrication plants within 30 km. We do not sell stock SKUs. Every platform project is cut, banded, and finished against your panel schedule, with openings for columns, pipe penetrations, and equipment bases located per your drawings. Send CAD files or marked-up plans through our Request a Quote page and we will respond with a fabrication proposal.

Industrial Platform Grating

Most factory mezzanines, maintenance walkways, and stair treads use welded carbon steel grating in the 19-space series (bearing bars at roughly 30 mm centers) or the tighter 15-space series (roughly 24 mm centers), the latter often chosen where small tools or heels could catch. Bearing bars run from 20×3 mm for light pedestrian walkways up to 100×9 mm for long spans and heavy equipment platforms; cross bars are typically pitched at 50 or 100 mm. Panel lengths and widths are cut to your layout rather than forced into standard sheets.

Surface treatment depends on the environment. Indoor dry mezzanines are often supplied untreated for site painting or painted; anything exposed to weather or washdown is normally hot-dip galvanized to ASTM A123; food, chemical, and coastal plants can specify stainless 304 or 316. Bearing bars are available plain or serrated. Because grating is engineered to span and deflection limits rather than a one-size load rating, tell us your support spacing and design load and we will match a section from the standard load tables — contact us for engineered load data rather than relying on generic figures.

Recommended Products

Welded steel grating is the default for platforms: bearing bars resistance-welded to cross bars give a rigid, one-piece panel that handles foot traffic, carts, and point loads from equipment feet. For equipment platforms carrying pumps, motors, or skids, we move up the same product line to heavy-duty sections — taller, thicker bearing bars toward the 100×9 mm end of the range — and add banding bars, kick plates, and cutout reinforcement where the layout requires. Matching grating stair treads with checker-plate or abrasive nosings complete the package. See the full range on our steel grating page.

Where the platform sits over chemical processing, wastewater, electroplating, or marine splash zones, FRP grating is often the better answer: molded or pultruded panels in orthophthalic, isophthalic, or vinyl ester resin resist corrosion that would consume galvanizing, and the gritted surface is inherently slip-resistant. Many plants mix the two — steel grating in dry areas, FRP around dosing and acid-handling zones. Browse other use cases on our applications overview.

Platform Safety Standards

Walking-working surfaces on industrial platforms in the US fall under OSHA 29 CFR 1910 Subpart D, which requires surfaces that support intended loads and are kept free of slip hazards — requirements grating meets through correct section selection and, where wet or oily conditions exist, a serrated bearing-bar surface. For dimensional and load-rating conventions, our export grating is fabricated to YB/T 4001.1 and cross-referenced to ANSI/NAAMM MBG 531, the manual most EPC specifications cite for span and deflection tables.

Production runs under an ISO 9001 quality system, hot-dip galvanizing follows ASTM A123, and CE documentation is available for European projects. We supply platform grating to EPC contractors, procurement engineers, and importers across the Middle East, Southeast Asia, Europe, Australia, and Latin America, with FRP also shipping to US buyers. For your specific support spacing and design loads, request a quote with drawings attached — we will return marked-up panel layouts and the relevant engineered load tables instead of guesswork.
