The weight of a 20-foot stick of K-rail, or “guard rail,” depends on several factors, including the gauge of the steel and the corrosion protection, which can range from none to hot-dip galvanized. On average, a 20-foot stick of K-rail can weigh anywhere from 200 to 500 pounds.
Higher-gauge steel with additional corrosion protection will weigh more than thinner gauges with no corrosion protection. Additionally, the density of the steel used to craft the rail can vary, adding to the overall weight.
Generally, the thicker the steel gauge and the higher the corrosion protection applied, the heavier the K-rail will be. To get an accurate weight of your specific K-rail, contact your supplier or the manufacturer.

How heavy is K-rail?
The weight of a K-rail, also known as concrete barrier, varies depending on the size used. The size of K-rails are typically 4 feet, 6 inches tall and 12 inches wide. A 4 feet rail weighs approximately 200 pounds, a 6 feet rail weighs approximately 270 pounds, and an 8 feet rail weighs approximately 350 pounds.
The lengthwise weight also depends on its length, with longer K-rails being heavier. For example, a 6 feet long K-rail will weigh approximately 334 pounds. Additionally, the weight can be altered depending on the concrete mixture used to make the K-rail.
Therefore, the exact weight of a K-rail will vary depending on the size and the concrete mixture used.
How long is a stick of K-rail?
A stick of K-rail typically measures 7.5-10 feet in length and approximately 33 inches wide, though it can vary by location and manufacturer. In the United States, it is sometimes referred to as guardrail, median barrier, or traffic barrier.
The K-rail is designed to reduce the amount of damage a vehicle can cause in a crash and to reduce the amount of traffic separation needed. It can be used as an edge barrier to prevent vehicles from entering protected areas such as grassy medians and shoulders, or it can be used as an inner barrier to reduce crashes on highways with multiple lanes of traffic.
The K-rail is made from robust steel and is bolted into place or filled with concrete to offer stability and support.
What are the disadvantages of K rail?
K rail is commonly used as a temporary barrier in regular traffic areas and construction zones, but there are some notable disadvantages of using this type of barrier.
The most significant disadvantage of K rail is the fact that it can be difficult to transport and set up. The sections of this rail are heavy and unwieldy, which makes it difficult to move from one area to another.
Additionally, the sections must be secured in the ground in order to stay stable and effective for traffic control, which is time-consuming and may also require additional tools and pieces of equipment.
Also, K rail does not provide much protection for pedestrians or vehicles in the event of a collision. This type of barrier is designed to be more effective for slowing down traffic rather than providing a physical barrier to stop it.
This means that collisions with these barriers can still result in significant damage to the vehicles involved.
Finally, K rail can be aesthetically unappealing due to its bright orange color. This can be especially disruptive to areas around major highways, as the orange color of the rail is quite noticeable.
What does the K in K rail stand for?
The “K” in K-rail stands for “K-type,” which refers to a type of concrete barrier used in construction projects. These barriers, often referred to as Jersey barriers, are modular concrete components used to separate lanes of traffic.
They are used for a variety of purposes, such as controlling traffic flow and creating a temporary barrier to divide lanes of traffic. K-rail is a trademarked name used by a specific company to refer to their own product.
The name is derived from the shape of the barrier, which is designed with a “K” shape that allows it to be easily transported and put together on site. K-rails are typically made from reinforced concrete and are typically a standard eight feet in length and two feet in height.
The barriers are usually placed in segments and can be strong enough to withstand crashes from vehicles such as trucks and buses.
Why are railways 4ft 8.5 inches?
The width of railways can be traced back to the mid-1800s when the first steam locomotives were developed in Britain. At the time, engineers standardized the width of the track to the London to Holyhead line — the “Highway of Romans” — at 4ft 8.5in.
The width was based on the wagons and carriages commonly used in England at the time, which had all been built with that size of wheels and axles.
This gauge of 4ft 8.5in became the standard for railways in England and then spread to other parts of the world. By the mid-19th century, Britain had implemented a railway network using the standard gauge, while Canada and many parts of Europe had adopted it.
With the development of rail lines in the US, railway engineers decided to adopt the same standard gauge rather than create their own specification.
Today, the 4ft 8.5in gauge is still used in railway systems all over the world, although some countries – such as Russia, Spain and China – have deviated from the standard.
What is the most common weight of rail?
The most common weight of rail used in railway construction is 115-lbs per yard (or 100-lbs per yard, depending on the source). The rail is also referred to as bull head rail due to its head being heavier than other rails and being flattened near the ends.
The rail is typically laid in a broken pattern, and is held in place by a combination of tension and specially designed fasteners. This type of rail is used for the majority of railway track construction and comes in different lengths, with the most common lengths being between 30 and 40 feet long.
It is important to note that the term “weight” in this context does not refer to the rail’s actual weight, but instead its resistance to wear caused by wheel and flange contact.
How heavy is a train track beam?
The weight of a train track beam can vary depending on the type of beam and its size. Steel beams typically come in weights of 20 to 5000lbs per a yard and the beam can range anywhere from 30 to 80ft in length.
Heavier beams are usually required for long spans such as when crossing a large body of water. Railroad bridges are also built with steel I-beams, however these beams can weigh as much as 45,000lbs. Composite train track beams have also been developed and used for shorter spans.
These can weigh slightly less than steel beams but can have higher performance characteristics.
Why do they call concrete barriers K rails?
Concrete barriers, also known as “K rails”, are a form of traffic barrier used for channeling traffic and providing a median. The name “K rail” derived from the shape of the barrier, which resembles the letter “K”.
The barriers are used to separate traffic on highways and roads in order to reduce the risk of head-on collisions. K rails are also useful for redirecting traffic away from accident sites and providing a median for separating opposing lanes of traffic.
They are often installed to form a semi-permanent arrangement, although some can be removed for easy vehicle passage. Additionally, K rails allow for greater flexibility in controlling the movement of vehicles, including turning traffic away from hazardous areas.
The barriers are also often used to section off construction areas on highways, freeways, and roads.
How wide are K-rails?
K-rails, also known as Jersey barriers, are an effective form of traffic control. They are usually made of concrete and are designed to minimize the potential for vehicle-pedestrian collisions. The width of a K-rail can vary depending on the manufacturer, but in most cases, the K-rail is 32 inches (81 cm) wide and stands 29 inches (73 cm) high.
The design of the K-rail helps to redirect vehicles moving at speeds of up to 55 mph (88 kph). Additionally, the vertical elements of the K-rail are usually tapered, allowing for greater flexibility if a driver inadvertently goes off-road.
What are the dimensions of a temporary K-rail?
K-rails, or temporary barrier systems, are most commonly composed of interlocking pre-cast concrete sections. Each section is 27” long and 12” high and has a weight of 190 lbs. K-rails can be connected to one another to create a variety of lengths, widths, and heights that fit any roadway or traffic barrier application.
The sections can also be filled with aggregate or soil to add additional stability. When filled, the two-foot-wide sections can weigh up to 260 lbs. To create barriers of different heights, sections can be stacked up on top of each other.
The maximum wall height with two-foot-high sections is usually seven feet. It is possible to go higher with custom sections, but the extreme forces can cause issues in terms of stability and anchorage.
How is rail width measured?
Rail width is commonly measured in millimeters or inches. Generally standard rail widths range from 95 millimeters (3.74 inches) to 125 millimeters (4.92 inches). This measurement refers to the width of the rail at its widest lower point, which also differs from the width of the head.
The head width of the rail is typically greater than the rail width by several millimeters. The rail width is determined by the type of train cars being used, the track configuration, and the weight capacity required for a specific application.
The wider the rail, the more weight the track can support. In addition, rail widths may also be increased or decreased to accommodate changes in grade. The track width must also be taken into consideration when determining the horizontal clearance that must be maintained to protect from lateral forces.
To measure the rail width, a rail gauge can be used to measure the distance between the top and bottom of the rail at its widest point.
What Is a highway K-rail?
A highway K-rail (also referred to as a barrier transfer machine or a Jersey barrier) is a type of traffic control device commonly used to separate opposing lanes of traffic or to close off sections of a roadway.
It is typically a temporary structure made of precast concrete or steel that is relatively easy to install or remove. K-rails are rounded on top, which helps reduce the risk of vehicles climbing over them, and are typically installed with a base plate that gives the barrier additional stability.
While K-rails are commonly used on highways and roads, they can also be used as perimeter barriers at construction sites, as guard rails in parking garages, or as a makeshift barrier around large objects like trees.
