Swaged Pressure-Locked AssemblyENQUIRY-BASED FABRICATION

Press-locked bar grating with clean lines and zero weld distortion.

Press-locked bar grating has cross bars mechanically press-locked (swaged) into notched bearing bars under immense hydraulic force without welding. This cold-forming process eliminates heat distortion, providing a completely smooth top surface, exact dimensional tolerances, and clean joint lines.

Continuous Mechanical Interlock

Standard and close-mesh spacing patterns available

304 / 316 / AL

Engineered Manufacturing Characteristics

Precision mechanical swaging provides structural integrity and aesthetic consistency.

No Heat Distortion

Cold mechanical swaging eliminates thermal stresses, delivering flat panels with tight tolerances.

Flush Surface Profile

Uniform top surface provides smooth rolling transitions for carts and comfortable foot traffic.

Precision Notch Fit

Deep hydraulic locking creates solid mechanical joints without weld spatter or discoloration.

Available Alloys and Finishes

Supplied in standard panels or cut-to-size fabricated sections per your drawings.
