Press-Locked Bar Grating Overview
Press-locked bar grating is manufactured by mechanically pressing notched cross bars into notched bearing bars under high pressure.
The construction creates a rigid grid with a relatively clean and uniform surface, making press-locked grating suitable for both industrial access systems and projects where appearance is also important.
Panels can be produced in different bearing bar sizes, spacing, materials, surfaces and finished dimensions according to project requirements.
Press-Locked Bar Grating Specifications
Press-locked grating is mainly specified by bearing bar size, spacing, material, surface, span and finished panel dimensions.
| Specification | Available Options | Selection Notes |
|---|---|---|
| Construction | Press-locked / pressure-locked | Bearing and cross bars mechanically pressed together |
| Material | Carbon steel, galvanized steel, stainless steel, aluminum | Select according to strength, weight and environment |
| Bearing Bar Height | According to grating specification | Influences load capacity |
| Bearing Bar Thickness | According to selected construction | Consider together with height and spacing |
| Bearing Bar Spacing | Standard or project-specific series | Affects open area and walking surface |
| Cross Bar Spacing | According to grating series | Defines transverse grid spacing |
| Surface | Smooth or serrated | Select according to traction requirements |
| Panel Size | Standard or custom | Confirm bearing-bar direction |
| Clear Span | According to support layout | Important for load selection |
| Load Requirement | According to project design | Verify against suitable load data |
| Edge Condition | Open or banded | Depends on finished installation |
| Finish | Mill, galvanized, painted or specified finish | Depends on material and environment |
| Fabrication | Cutting, banding, notching and cut-outs | According to drawings |
Press-locked products are available in multiple spacings and bearing-bar configurations; some close-mesh press-locked configurations are also used for ADA-related requirements, but this depends on the exact product specification and installation—not every press-locked panel is ADA compliant.

Press-Locked vs. Welded Bar Grating
Both provide rigid open-grid flooring, but the way the bearing and cross bars are connected creates different product characteristics.
| Comparison | Press-Locked Bar Grating | Welded Bar Grating |
|---|---|---|
| Construction | Bars mechanically pressed together | Cross bars welded to bearing bars |
| Grid Appearance | Clean and uniform | Conventional industrial appearance |
| Material Range | Steel, stainless steel, aluminum | Commonly carbon and galvanized steel |
| Surface | Smooth or serrated | Smooth or serrated |
| Architectural Use | Particularly suitable | Possible but more industrial |
| Typical Use | Flooring, architecture, walkways | Industrial flooring, platforms, access |
Choose Press-Locked Bar Grating when a clean grid appearance or press-locked construction is preferred.
Choose Welded Bar Grating for conventional industrial flooring and access systems.
Case Study : Aluminum Press-Locked Grating for Data Center Service Walkways
This project required lightweight press-locked grating panels with multiple finished dimensions and equipment cut-outs for elevated service access inside a data center.
Project Requirement
A facility contractor required open grating panels for maintenance walkways around cooling equipment, cable routes and service areas.
The layout included multiple panel dimensions and several openings around fixed equipment. The finished panels needed a consistent grid appearance across adjacent walkway sections.
Manufacturing Solution
Aluminum press-locked grating was selected to reduce panel weight while maintaining an open walking surface.
Bearing-bar direction, panel dimensions and cut-out locations were prepared according to the approved layout drawings.
Panels were cut to finished dimensions, with openings and notches produced around cable routes and equipment. Cut edges were banded where required.
Inspection & Packaging
Panel dimensions, grid alignment, bearing-bar direction, cut-outs and banding were checked before shipment.
Panels were identified according to installation position and packed by area to simplify onsite handling.
Press-Locked Bar Grating FAQs
Press-locked bar grating is made by mechanically pressing notched cross bars and bearing bars together to form a rigid open-grid panel.
The primary grid connection is created through high-pressure mechanical locking rather than the welded construction used in Welded Bar Grating.
Common materials include aluminum, carbon steel, galvanized steel and stainless steel.
Yes. Smooth and serrated surface configurations are available depending on the selected product specification.
Selected close-mesh press-locked configurations can meet ADA-related requirements, but compliance depends on the exact spacing and installation conditions.
Yes. Panels can be cut and fabricated according to project dimensions.
Yes. Cut-outs, notches and banded openings can be produced according to fabrication drawings.
Bearing bar size should be considered together with clear span, spacing and required load using appropriate load data.
