Product Specification
| High Light | High Strength-to-Weight Ratio Steel Bar Grating ，Minimum Deflection Swage-Locked Steel Grating ，Maximum Safety Platform Grating | ||
Our swage-locked steel bar grating has become the preferred choice for a diversity of applications, including industrial, architectural and construction, and municipal engineering applications, due to its high strength-to-weight ratio, minimum deflection and maximum safety.
Our swage locked steel grating is manufactured by a swaging and welding process. In this process, the cross bars are inserted into pre-punched holes (usually diamond-shaped holes or round holes) in the bearing bars and then welded at each intersection, thus forming a positive mechanical connection permanently.
As a rule, the cross bars are twisted square steel bars or round steel bars.
In terms of premium carbon steel such as Q235, the welding operation involved in the production process is the CO2 gas-shielded welding process. But the laser welding operation is also available at TSG if the customer needs us to do so.
In terms of stainless steel such as 304, the welding operation involved in the production process is the laser welding process.
Our swage locked steel grating is manufactured from premium carbon steel and stainless steel. Our surface finishing for our swage locked steel grating panels includes mill finish, hot dip galvanizing and powder coating or PVDF painting in all standard RAL colors for carbon steel materials. And for stainless steel materials, the electro-polishing is also available from our factory.
Our swage locked steel grating is available in three types of bearing bars: Rectangular flat bar, I-shaped steel bar and T-shaped steel bar.
Please see the following sketch to have general knowledge of these three types of bearing bars.
