Guardrails are used for safety and barrier purposes and are an integral part of various industrial structures. These assemblies are typically installed at platform ends and are incorporated within mezzanine structures in industrial sites, such as warehouses. They are used on highways as a protection barrier against vehicle impact, to prevent falls, and in production areas. Standard guardrail fabrication materials include variations of stainless steel, a material recommended because of its durability. Wooden guardrails are another common barrier material. There are numerous variations of standard guardrails, which must comply with OSHA standards. Both single and double railing systems are a standard guardrail installation option.
The most common types of guardrails include:
W-beam
Curved
Bolt-on
Drop-in
W-beams are the standard traffic and highway safety rails and are constructed in high gauge steel. To protect against environmental conditions, this type of beam is fabricated with zinc coatings and weather (resistant) coated materials.
Curved guardrails feature a convex or concave-shaped rail and are used to provide protection on roadways and highways that have a bend radius to them. These units are usually prefabricated to fit the required dimensions of the site where they will be installed. Concave rails are those in which the rail curves in towards the vehicle, while convex rails are those that curve away from the vehicle.
Drop-in rails feature brackets that allow post sections to slide into the structure upon installation. This type of railing is easily accessible.
Bolt-on rails involve specific installation with hand tools and drills, though the hardware for this type of railing is typically included by the manufacturer. Single, double, or triple rails may be selected for an application.
Pedestrian walkway protection
Workstation and transformer area barrier
Protect equipment from forklift damages
Protect building from damage (ie, walls and doors)
Installed along roadways to prevent and minimize accidents
A standard guardrail system is mounted to the floor by base plates, which are fastened with anchor bolts. Each guardrail system also includes columns that are commonly fabricated from steel. Such columns, or posts, are often pre-drilled by the manufacturer and include the hardware for installation. Standard galvanized steel systems (specifically 12-gauge) provide durability and are often fabricated in curved, 90-degree variations, for traffic areas. Other variations include cylindrical steel beams and flatter beams, featuring ribbing. For indoor and outdoor areas, railings are typically painted OSHA yellow. The type and amount of beam railing vary according to the application requirements. For instance, the railing can consist of one to three beams and the beams may be coated with UV resistant polyurethane sleeves.
Box beam guardrail, a kind of highway barrier, is not as common as traditional W beam or thrie beam guardrails, but it caters the need of appreciation of the beauty and is widely used not only on highways, but also in parks, picturesque bridges, etc.
The same as W-beam guardrails, it is made of high quality steel and plated with superior zinc coating or coated with PVC coating. Thereby, it is anti-rust and durable enough to endure the impact force. Additionally, there is no need of paying much money on the maintenance of the box beam guardrail, which makes it cost effectively in the long run.
Box beam guardrails can be used on bridges.
Advantages:
Anti-rust
Corrosion-resistant
Durable and well-constructed
Designed to have a long service life
Can be used with or without blocks
Easy to install and repair
No need of maintenance
The box beam guardrails we supply:
According to the shape of the box beam guardrail, we can divide them into two types: square and rectangular. Meanwhile, we can also provide open box beam guardrail depends on your requirements.
Square box beam guardrails
Rectangular box beam guardrails
W-beam guardrail has a section or profile of W shape, it is also named as two wave beam guardrail. This is the major type of beam barriers for highways safety with symmetrical designs on each side of the beam. We supply two kinds of finishes for W beam guardrail panels: hot dipped zinc coating or plastic coating. According to the fabricated shapes, our W-beam guardrails can be divided into two types: the straight line w-beam,or the curved beams.
How to choose straight W beam or Curved Beam used for your uses?
The straight W-beam guardrail can be lined up for transitioning smoothly and is suitable to the curves with a radius greater than 45m. For the radius less than 45m, the pre-curved W-beam guardrail product exploits its advantages to a full.
W beam guard railings can be used in expressway and highways to absorb maximum energy of the impact force when collision occures and reduce harms to cars and people. It can also protect the vehicles against skidding off roads, especially mountain roads and bridges and prevent the pedestrians from the danger of walking across highways.
