Technical resource

Welded grating joins bearing bars and cross bars by welding; press-locked grating locks them mechanically. Press-welded (resistance-welded) grating belongs to the welded family, not the press-locked family.

- Welded industrial strength
- Press-locked clean appearance
- Spacing and opening differences
- Finish and fabrication sequence

 

 













## Short answer

Choose between welded and press-locked grating by the joining method, bar geometry, openings and finished-panel requirements. Compare load and deflection data for each offered configuration at the same clear span; the construction name alone does not establish a stronger panel.

Both are open-grid products with load-carrying bearing bars and connecting cross bars. Resistance welding uses electrical heat and pressure to fuse the intersection. Press-locking mechanically secures the intersection; pressure in the manufacturing process does not make it resistance welding. Terminology and selection reference: [ANSI/NAAMM MBG 531-24 (2024)](https://naamm.org/publications/metal-bar-grating-manual/).

For quotation, the construction type should be checked together with support span, load requirement, bearing bar direction, opening size, surface type, finish and fabrication details. A product name alone is not enough to confirm performance or price.





## Main comparison table

| Welded grating | Welded joints between bearing bars and cross bars for common industrial flooring and access products |
|---|---|
| Press-locked grating | Mechanically locked bar layout with cleaner visual lines and close mesh options |
| Typical focus | Welded focuses on industrial strength and cost efficiency; press-locked focuses on appearance, alignment or smaller openings |
| Surface options | Both may be smooth or serrated depending on walking surface requirements |
| Finish options | Both can be hot-dip galvanized, painted, powder coated or supplied in stainless material by project |













Selection workflow

## How buyers should compare welded and press-locked grating

The connection method matters, but it should be reviewed together with load, span, opening, finish and fabrication details.







### 1. Confirm application

Industrial platforms, drainage covers and maintenance walkways commonly start with welded grating.





### 2. Confirm appearance needs

Press-locked grating can be reviewed when a clean, aligned or architectural-looking grid is requested.





### 3. Check load and span

Bearing bar size, spacing and support span still decide whether the specification fits the load condition.





### 4. Review openings

Close mesh, dropped-object control or project-specific open area may affect the product type.





### 5. Choose surface

Smooth grating suits general use; serrated grating should be reviewed for wet, oily or outdoor walking areas.





### 6. Prepare drawings

Cutouts, banding, side plates, frames and fixing clips should be checked before quotation.















## Application comparison table

| Industrial platforms | Welded grating is often the practical option for plant floors, access platforms and maintenance decks |
|---|---|
| Walkways and catwalks | Welded or press-locked can be reviewed by load, appearance and surface condition |
| Drainage covers | Welded grating is common where removable panels, open area and load support are required |
| Architectural or visible areas | Press-locked grating may be considered when the visual grid and bar alignment matter |
| Close mesh requirements | Press-locked or close mesh styles can be reviewed when smaller openings are needed |





## Welded grating is usually the practical starting point

For industrial platforms, walkways, trench covers, drainage covers and equipment access areas, welded steel grating is usually the first construction type to review.

It is familiar to industrial buyers because it balances load support, open area, cost efficiency and finish options. The RFQ still needs panel size, bearing bar size, spacing, support direction, surface finish and drawing-based fabrication details.

Press-locked review

## When press-locked grating should be considered

Press-locked grating is useful when the project is not only asking for open-grid flooring, but also for a more regular visual pattern or a specific mechanically locked construction. It can fit certain public-facing industrial areas, architectural metal flooring, close mesh panels and project drawings where appearance and opening layout are important.

Because press-locked grating can be more specification-sensitive, buyers should send drawings or clear sketches early. Bar size, bar spacing, cross bar spacing, panel direction, banding and finish should be confirmed before pricing.

Press-locked grating is most useful when clean alignment, close mesh or visual consistency is part of the project requirement.







## Specification factors

| Connection method | Welded joints or mechanically pressed cross bars |
|---|---|
| Bearing bar data | Height, thickness, spacing and direction of the main load-carrying bars |
| Cross bar data | Cross bar type, spacing and appearance requirement |
| Surface type | Smooth or serrated depending on walking environment |
| Drawing requirement | Panel size, bearing bar direction, opening size, edge banding and fixing method |
| Finish | Hot-dip galvanized, painted, powder coated, mill finish or stainless material by project |













## Common purchasing mistakes to avoid

- Choosing press-locked only by appearance without checking load and support span
- Choosing welded only by cost without reviewing surface condition or corrosion exposure
- Sending panel size without bearing bar direction
- Forgetting cutouts, banding, side plates, frames or fixing clip details
- Using indoor finish assumptions for outdoor or wet environments





## RFQ checklist

| Product type | Welded grating, press-locked grating, close mesh grating or not yet decided |
|---|---|
| Panel data | Panel width, length, bearing bar direction, support span and quantity |
| Bar data | Bearing bar size, bearing bar spacing, cross bar type and cross bar spacing |
| Application | Platform, walkway, drain cover, architectural area, stair tread or maintenance access |
| Order details | Finish, drawings, destination, packing preference and expected delivery timing |













## FAQ





What is the difference between welded and press-locked grating?

Welded grating uses welded cross bars and is common for industrial strength and cost efficiency. Press-locked grating uses pressure-fitted intersections for cleaner alignment and close mesh options.



When should welded grating be used?

Welded grating is often reviewed for industrial platforms, walkways, drainage covers and general access flooring where strength and practical cost are important.



When should press-locked grating be considered?

Press-locked grating may be considered for architectural areas, close mesh requirements, cleaner appearance or projects where precise bar alignment matters.



Can welded and press-locked grating both be galvanized?

Yes. Both grating types can be hot-dip galvanized after fabrication when outdoor corrosion resistance is required.



What information is needed for a welded or press-locked grating quote?

Send grating type, panel size, bearing bar size, spacing, finish, load requirement, drawings, quantity, destination and packing notes.
