Pultruded grating is ideal for applications that require high strength or where the grating is subjected to excessive loads or impacts.
6. Perforated Plank Grating
Perforated plank grating is a common type of grating used in outdoor walkways and pedestrian bridges. It is formed by punching holes in flat sheet metal and then slitting it into planks. The planks are then welded or bolted to a support structure. They offer excellent traction due to their perforations and are also easy to maintain.
7. Bar Grating
This type of grating is constructed by welding bearing bars and cross rods at the intersections to create a rigid one-piece panel. It is ideal for loading docks, mezzanine floors, and other applications where safety and durability are required. Bar grating is one of the most popular types of grating due to its versatility, strength, and ease of installation.

Riveted Grating Construction
Riveted grating is the oldest way of constructing metal gratings and is a popular choice for historical preservation projects. The grating panels are constructed by joining flat bars and securing them together using rivets. The rivet construction provides excellent load capacity, making this type of grating ideal for heavy industrial applications. The riveted grating also provides a secure non-slip surface, making it suitable for pedestrian walkways and floors.
Step-by-Step Riveted Grating Construction
The construction process of a riveted grating is quite labor-intensive and involves the following steps:
- Cutting and punching the bearing bars and cross bars to size.
- Laying out the bearing bars and cross bars in the assembly jig and clamping them together.
- Drilling the holes for the rivets.
- Inserting the rivets and hammering them into place.
- Trimming off the excess rivet heads and welding the panels together.
- Grinding and de-burring the grating panels to ensure a smooth surface.
Benefits of Riveted Grating Construction
Riveted grating has several benefits over other types of grating. Firstly, it is extremely durable and can withstand heavy loads, making it ideal for industrial applications. Secondly, the riveted construction ensures a secure non-slip surface, which is critical for pedestrian walkways and floors. Finally, the use of rivets means that the panels can be easily replaced, thus reducing maintenance costs and downtime.
