Process comparison
Riveted vs Welded vs Press-Locked — an Honest Comparison
Riveted grating is the oldest of the three formats: bearing bars and cross bars clamped together and joined by rivets. It is a legacy, derived format for us — quoted to drawings and assessed per project, never a stock program. Our in-house lines are electro-forged welding and press-locking, and for most modern floors those panels do the same job faster. Here is what each construction actually does.
Why riveted still gets specified: bridge-deck and heritage-refurbishment drawings carry riveted details forward, the flat-top walking plane has a traditional appearance engineers trust, and the riveted joint is often described qualitatively as damping vibration under traffic. If your specification demands rivets, send the drawing. If it allows a modern process, we will show you the equivalent.
| Dimension | Riveted | Welded / Electro-Forged | Press-Locked |
|---|---|---|---|
| Forming principle | Bearing bars and cross bars clamped and joined by rivets through punched holes | Every bearing-bar / cross-bar intersection resistance-forged under pressure | Cross bars mechanically pressed into notched bearing bars — no welding |
| Load behavior | Heavy sections for bridge-deck duty; a proven legacy record on old structures | High load capacity at wide spans; joints cannot work loose | Very uniform load distribution; suited to pedestrian traffic |
| Walking surface | Flat top by construction — the classic riveted look | Flat panels, plain or serrated for grip | Extremely flat — no weld heat, no distortion |
| Vibration under traffic | Riveted joints described qualitatively as damping vibration | Rigid one-piece panel, quiet underfoot | Rigid panel, uniform feel underfoot |
| Typical use today | Bridge decks, heritage refurbishment, like-for-like replacement | Platforms, walkways, trench covers, guardrails | Municipal trench, tree pits, facades, fine floors |
| Our lines | Quoted to drawings, assessed per project — not our in-house line | In-house — electro-forging line | In-house — press-lock machine |

Joint anatomy
The Riveted Joint — And the Joints We Make In-House
1 · The riveted joint
Bars are clamped, holes punched, and rivets driven and headed at every intersection — the legacy craft method. We quote riveted panels to your drawings and assess each project on its own merits.
2 · Our electro-forged equivalent
The modern replacement for riveted floors on new decks: every intersection pressure-forged in one pass on our in-house line — same open mesh, same flat top, faster to produce.
3 · Press-locked for close mesh
Where a riveted look pairs with fine spacing, press-locked panels interlock bars mechanically down to 11 / 11 mm mesh — flat, no weld heat, made on our second in-house line.
Why buyers ask for riveted
What Riveted Buyers Are Really Buying
The flat-top walking plane
Flat-top riveted grating keeps the whole walking surface level — the reason it appears in historic floors and bridge decks. Our plain-top welded and press-locked panels give the same level plane for new work.
High-load legacy duty
Riveted panels carry heavy sections for deck duty. For new high-load floors we build heavy-duty welded grating from 20×3 mm to 100×8 mm bars — the modern equivalent, quoted with load context on request.
Samples before you commit
Riveted panels or their modern equivalents, sampled in 5–7 working days so you can check construction and finish in hand. Small trial orders welcome — no fixed minimum, quantities follow your fabrication plan.
Applications
Where the Riveted Format Lives On
Most riveted enquiries arrive as drawings rather than catalog numbers — a deck to match, a heritage floor to repair, a specification written decades ago. These are the four places the format still turns up.
Bridge & viaduct decking
Legacy riveted details carried forward in deck drawings — quoted to the original or replacement designation.
Heritage & refurbishment floors
Like-for-like repairs where the flat-top riveted appearance is part of the fabric being conserved.
Plant platforms & walkways
New-build floors specified "riveted" — usually served faster by our welded equivalents at the same duty.
Stair treads & landings
Older stair drawings with riveted treads — matched to drawings or re-specified as welded treads.

Materials & test documents
Every heat of Q235B, SS304 or SS316 enters production with its mill test certificate verified at goods-in — the first of our five QC stages, whichever construction your project ends up using. Panels leave with documentation, not promises:
- Mill test certificate to EN 10204 Type 3.1
- Factory inspection report with every shipment
- Declaration of Conformity prepared per order destination
Standards & compliance
Produced to Recognized Standards — Documents on Request
ANSI / NAAMM MBG 531
Grating produced to MBG 531 reference practice — and riveted enquiries checked against your legacy designation before quoting.
ASTM A123 / ISO 1461 HDG
Galvanized coating thickness checked by sampling on every galvanized batch — riveted-style or modern panels alike.
CE & SGS tested
Certified & tested, reports on request — we show documents you can verify, not a certificate wall.

FAQ
Frequently Asked Questions
Do you make riveted grating on your own lines?
No — and we would rather say so than oversell. Riveting is not one of our in-house processes; our lines are electro-forged welding and press-locking. Riveted grating enquiries are quoted to drawings and assessed per project, and for most modern projects we recommend our welded or press-locked equivalents instead.
Why is riveted grating still specified at all?
Riveted construction is the legacy method that welded grating replaced, and it survives in two places: bridge-deck and heritage-refurbishment drawings that carry riveted details forward, and buyers who value the traditional flat-top look. The riveted joint is also described qualitatively as damping vibration under traffic. Where the specification allows a modern process, electro-forged panels do the same open-mesh job with faster production.
What are the lead time and order terms for a riveted enquiry?
Riveted panels are quoted to drawings, so everything starts with a free drawing review inside the 24-hour quote. Samples then take 5–7 working days and production runs 15–25 working days after drawing confirmation, hot-dip galvanizing included. Small trial orders are welcome — quantities are set by your fabrication plan, not a fixed minimum.
