Bollards vs. Jersey Barriers: Which is More Effective?
When choosing between Jersey barriers and bollards, it’s important to consider the speed, type of traffic, and likely crash pattern.

One of the major distinctions in specialization is whether foundries work with ferrous metals, non-ferrous metals, or both.
The forging process can produce parts with superb mechanical properties with minimum waste.
Stainless steels are highly corrosion resistant—however, stainless steel applications can still remain at risk to surface damage.
Aluminum contributes to more than 8% of the earth’s core mass. However, it is difficult to refine compared to other metals, such as iron.
To understand why stainless steel is rust-resistant, and how this resistance breaks down, it is helpful to understand how these alloys are different than other steels.
Steel comes in many grades, specifications, shapes, and finishes—the World Steel Association lists over 3,500 different grades of steel, each with unique properties. The various types mean that steel can by widely used in infrastructure, appliances, vehicles, wind turbines, and many more applications. Optimizing
Wherever people and cars are in close proximity, traffic safety is of heightened concern. Near playgrounds and schools, in parking lots and multiuse areas, aggressive driving is a safety risk for pedestrians. Speed reduction is one way to protect people in these areas. Slower traffic speeds
Carbon steel and stainless steel have the same basic ingredients of iron and carbon. Their main difference is alloy content—carbon steel has under 10.5 percent alloy
People often assume that cast iron and wrought iron are interchangeable terms for early iron work, but there is a world of difference.
Metalworkers have used the same casting processes for millennia, with the first castings dating back to the 4th century BC in China.
The presence of iron in everyday life began in about 1200 BCE, encompassing a wide range of uses from farming implements to weapons of war. Blacksmiths became a critical profession, working with iron to change its properties and shape the material into tools. Every village and town would have a blacksmith’s shop, where sickles, plowshares, nails, swords, candlestick holders, and more were produced.
For those buying barbeques, however, the choice of stainless used is often 304 vs. 430. (430 is also used for various truck parts.)
We’ve seen a recent trend in tree grates being repurposed by homeowners, artists, and contractors—as cast iron décor for use all around the home!
Hardscape provides both structural support and a complementing frame. It may sometimes be the less-noted aspect of the landscape architect’s work, but the type and placement of hardscape is vital for managing water, erosion, light, space, and safety.
A unique combination of exploration, community, challenge, and freedom mean that skateboarding can attract kids who do not enjoy participating in team sports, or for whom the financial burden of team sports is too high.
Steel’s affordability makes it an ideal metal for many projects. Stainless steel, on the other hand, is more expensive,
According to a 2019 report from the American Road and Transportation Builders Association, there are 47,000 structurally deficient bridges across the US.
Managing rain, storm, and flood water is a growing concern for homeowners in changing local climate.
Traditionally, planners see road safety as a “Three E’s” problem, solved through engineering, education, and enforcement.
