Steel lintels are primarily made from pre-galvanised steel that is shaped through cutting, roll-forming, or manipulation.
Steel lintels play a crucial role in construction, providing structural support over openings like doors and windows. Their manufacturing process is focused on creating strong, durable beams.
The Manufacturing Process
Based on typical methods, the process for creating steel lintels involves key steps:
- Material Selection: The primary material used is pre-galvanised steel. This material is chosen for its inherent properties, which include a protective coating already applied.
- Cutting: Large sheets or coils of pre-galvanised steel are precisely cut to the required dimensions for the lintel.
- Shaping: The cut steel is then formed into the desired lintel profile. This shaping is achieved through specific techniques:
- Roll-Forming: The steel is passed through a series of rollers that progressively bend it into the final shape. This is a common method for producing standard profiles efficiently.
- Manipulation: This can involve other methods like bending, pressing, or welding to achieve more complex or custom shapes.
These processes ensure the steel lintel has the necessary strength and profile to bear the load above an opening.
Durability and Benefits
One significant advantage of using pre-galvanised steel is its enhanced resistance to environmental factors. Steel lintels made this way are:
- Less affected by rust.
- Less susceptible to erosion.
This corrosion resistance is key to guaranteeing many years of reliable use in various building applications.
Choosing lintels made from appropriately treated steel ensures long-term structural integrity and reduces maintenance needs.
