A metal fabrication project involves various steps and techniques; this allows craftspeople to produce custom railings and other structural components. Capitol Iron Works assists clients through the consultation stage so they know what materials can benefit their project. Fabricators shape metal and apply finishing techniques to provide durable products that align with a client’s preferences. Here is more information on metal fabrication techniques:
Planning a Metal Fabrication Project
As you search for “metal fabrication services near me,” look for a company that provides consultations. During design consultations, clients can bring measurements and drawings of their planned project; fabricators will use these to create precise renderings. Before metal fabrication begins, designers evaluate the project’s structural requirements and intended function. This helps make sure the metal structure performs as intended.
Determining how much weight the finished project will need to support helps fabricators select appropriate materials. Stainless steel supports structural components that require high strength, while wrought iron is often used for ornamental work. Some metal projects may be outdoors in harsh conditions, and specific metals, such as steel and aluminum, offer corrosion resistance.
Shaping the Metal
Metal fabrication companies that shape pieces in-house help make sure that projects are completed seamlessly. Fabricators use different techniques to shape metal into a finished product; this allows them to make intricate designs, such as decorative scrollwork for railings and gates. Some techniques include:
Cutting: Shearing is a quick, efficient way to cut straight lines, while laser cutting can cut metal up to about 30mm thick. Some fabricators use plasma cutting, which melts metal to cut it. Water jet cutting uses a cold process for heat-sensitive materials.
Forming: Fabricators use specialized equipment to bend metal, such as CNC machines. Rolling metal shapes it into cylindrical components. To create complex designs, fabricators can stretch metal sheets.
Joining: Welding creates secure joints between metal pieces. If welding is not ideal for a specific project, riveting provides a reliable alternative. This joining method uses small fasteners to connect metal components.
Finishing the Fabrication
Once a metal fabrication piece has been formed, it may need finishing processes and coatings to become smooth and extend its lifespan. Grinding smooths weld seams, which helps create a seamless appearance. Deburring removes metal fragments; this helps eliminate sharp pieces that may cause injury or create weak joints.
Metal fabrication services apply powder coatings on some metal projects to protect them against corrosion and UV rays. This finish bonds to the metal, creating a durable surface, and it can last longer than regular paint. There are a variety of colors available, so clients are able to customize the appearance. Clients are also able to provide a color sample, which allows fabricators to match the appearance of a metal project to surrounding elements or a specific style. Powder coating is ideal for outdoor railings, helping them withstand damage from weather elements.
For increased corrosion resistance, fabricators are able to use an anodizing process. It is useful for aluminum, where it creates an oxide layer. This process is able to increase the hardness of a surface, and it helps resist scratches. Another technique that helps improve durability is plating. This adds a layer of different metal types onto the surface of a fabrication product. Some plating materials may include zinc, silver, nickel, and gold.
Using the Right Technique
Using a specific fabrication technique depends on the project’s intended use and size. Intricate decorative elements on railings may require precise shearing, while some large structures need water jets to cut through thick metal sheets. Fabricators often use several techniques together. Metal railing fabricators may:
Laser-cut the metal
Bend the material into posts and balusters
Weld posts and balusters to handrails
Grind welded joints at the ends of balusters
Apply protective coatings before installation
Work With Metal Fabricators
A metal fabrication company produces intricate and bespoke pieces, so clients can have durable structures that are aesthetically pleasing. Various techniques allow fabricators to precisely cut and shape the metal to align with a client’s design. This allows fabricators to make curved structures, such as spiral staircases, or complex geometric designs. Capitol Iron Works is also able to repair and replace existing metal structures to fix damage and enhance structural stability.
