The roll forming method is a highly efficient forming process that is frequently used in the production of road barriers. Thanks to this method, the basic elements of the barriers are produced by making the steel plates suitable for the desired profiles and dimensions.
Details of the Roll Forming Stage
Steel Plate Feeding:
Steel plates of a certain width and thickness are fed into the production line in coils or in the form of flat sheets.
Sheets are generally preferred as galvanized or specially coated. This ensures the longevity and corrosion resistance of the barriers.
Forming Bearings:
The sheet is passed through a series of forming rolls arranged consecutively.
Each roll applies pressure to the sheet at a certain angle and with force, creating the desired profile.
The design of the rullas is specially prepared according to the barrier profile to be produced.
Progressive Forming:
The sheet takes shape gradually as it passes through each roll.
The first rolls give the slab a general slope, while the later rolls create more detailed profiles.
In this way, even barrier profiles with complex cross-sections can be produced.
Punching and Cutting Operations:
When necessary, operations such as drilling and cutting are performed on the plate during or after shaping.
These operations are necessary for joining barriers with each other or for installing additional parts.
Final Check & Cut:
After the profile is produced in accordance with the desired dimensions and tolerances, the final control is made.
Next, barrier elements are obtained by cutting them to the specified lengths.
Advantages of Roll Forming Method:
High Efficiency: It provides the opportunity to produce a large amount of profiles in a short time.
Low Cost: It reduces unit costs as it is suitable for mass production.
High Precision: All profiles are produced with very similar features.
Flexibility: Barriers can be produced in different profiles and sizes.
Automation: A large part of the production process can be automated.
Types of Barriers Using the Roll Forming Method:
Side barriers: They are used on the roadsides to prevent vehicles from leaving the road.
Medium barriers: Used to separate vehicles coming from the opposite direction.
Bridge barriers: It is used to ensure safety on bridges.
Barriers in tunnels: It is used to ensure security and guidance in tunnels.
Result
The roll forming method is one of the most important methods used in the production of road barriers. Thanks to this method, barriers can be produced with high quality and economically. The technologies and materials used in the manufacturing process directly affect the durability and longevity of the barriers.
