19W4 Serrated and Non-Serrated Bar Grating

Serrated grating offers a particular advantage when used on stairs or escalators where it tends to be less prone to slipping than non-serrated models. On busy paths and walkways, an anti-slip design is essential for preventing accidents and injuries.

However, serrated grating is easier to install and remove than non-serrated alternatives. If you’re looking for something that’s both secure and quick to swap out, serrated grating may be a good option for your venue or business.

Overall Bar Grating Advantages:

• High strength – to- weight ratio
• Corrosion, impact, fire, and chemically resistant
• Non-slip surface
• Affordable and obtainable

Overall Bar Grating Disadvantages:

• Can be expensive
• If not treated, can be susceptible to rust
• Not aesthetically pleasing
• If not welded, may be susceptible to theft

Commercial sectors that commonly employ steel grating include marine and oil rigs, food and beverage processing, and factories and manufacturing plants.

Both serrated and non-serrated grating have a variety of applications, including industrial, residential, and commercial uses.

The construction industry uses serrated grating in areas that require secure footing, yet need to be able to provide some give in case people trip or a heavy object falls against it. For example, many fire escapes and ladders employ serrated bar grating on both sides of handrails. Another example would be anywhere an open balcony needs a secure but soft railing surface that won’t break under pressure (i.e., on cruise ships).

Landscapers often use serrated bar grating for wood decks or as fencing around trees and garden beds. It is especially popular in outdoor settings due to its weatherproof design and ease of use throughout all seasons.

Serrated grating is made in two ways, both of which are pretty simple to achieve.

1) Serrated grating can be created via machining, which involves running a saw along a bar-shaped piece of metal until its edges become knife-like in appearance although the result is not sharp like a blade. When formed this way, bar grating can be locked, riveted, or welded.

2) Perforated steel sheets can be stretched to create diamond-shaped openings between threads of steel. This is sometimes called “expanded metal” rather than bar grating.

Bar grating is easy to weld. In fact, to function properly as stair treads, platforms, or flooring, bar grating must be locked, riveted, swaged, pressure-locked, or welded in order to connect bearing bars and cross bars.

Fusing the bars through welding creates the rigidity and strength required for the product to function. Plus, welding is the most economical option. That said, welding forms a permanent joint while locking does not.

Welding serrated grating requires more precision and skill but produces a consistent, accurate end product that lasts far longer than its counterparts.

Non-serrated grating is sometimes subjected to heat treatment to increase its hardness and durability. Generally, heat treatment requires a temperature range between 772 and 1382 degrees Fahrenheit for a set amount of time (usually an hour). Serrated bar grating also requires a certain level of rigidity, but it doesn’t need to be as hard as non-serrated grating.
