What Is Press-Locked Steel Grating?

Press-locked steel grating is a series of vertically positioned metal bars joined to perpendicular cross bars at specified intervals, which creates a load-bearing panel with a smooth appearance.

Press-locked steel grating is a series of vertically positioned metal bars joined to perpendicular cross bars at specified intervals, which creates a load-bearing panel with a smooth appearance. It supports the same loads as welded grating, except it’s formed with enormous hydraulic pressure.

 

This bar grating type is manufactured from carbon steel and stainless steel in dovetail or swaged constructions. Optional serrated surfaces provide increased traction for wet, slippery, or hazardous environments.

 

Press-locked steel grating is fabricated using tremendous hydraulic pressure to bond the two close-tolerance slotted bars together, permanently locking crossbars into notched bearing bars. This results in a firm, rigid connection and bi-directional flush surface featuring a clean, aesthetically pleasing look.

 

Pressure-locking methods

The two prominent pressure-locking methods are swaging and dovetailing. Both have similar joining methods and can be produced to tighter tolerances than welded grating, but they have unique characteristics.

 

Dovetail grating

This is a tightly locked and rigidly stable panel grid with clean lines and an aesthetically pleasing appearance. Manufactured by deforming pre-punched bearing bars and cross bars assembled in an egg-crate configuration under intense hydraulic pressure, this dovetail grating permits heat, light, and air to pass easily.

 

Swage-locked grating

This press-locked grating type is fabricated by inserting hollow tube cross bars into bearing bars with pre-punched holes. The crossbars are then permanently secured using a swaging reshaping process. With cross bars recessed below the top surface of the bearing bars, duty swage-locked steel grating offers clean lines and a distinct appearance.

 

Application

This bar grating type is often called press grating or pressure-locked grating, but the end product is the same regardless of name. The combination of high performance and striking visual appearance makes press-locked bar grating incredibly versatile. It’s perfect for a range of applications.
