Metal incorporates seamlessly to define function and elevate interior environments.

Through expert fabrication, adaptive metal solutions bring unique artistic concepts, clear communications and natural flow to our built spaces. Custom metalwork translates specialized visions into tangible forms with integrity and beauty.

Decorative Metalwork Techniques

Forming and Bending

Forming processes sculpt raw architectural metal fabrication and bars into graceful curves, angular structures, and complex shapes. Roll forming and plate bending utilize presses and rollers to produce contours. Tube bending wraps metal pipes into flowing organic lines. These techniques impart structural integrity while creating aesthetic appeals through dynamic curves and angles.

Joining Techniques

Cut and formed components come together through expert joining applications. Welding techniques like MIG, TIG and gas fuse elements with structural permanence. Mechanical fasteners such as rivets and screws provide decorative finishes. Fabricators masterfully blend these methods, sometimes combining multiple joins for visual complexity in railings, grilles and more. Precise jigs and fixtures ensure accuracy at every stage.

Surface Finishing

A refined and protected surface elevates any architectural metal fabrication After forming and joining, various surface finishing processes beautify and preserve the metal. Powder coating electrostatically applies a colorful, durable smooth finish. Etching and antiquing use acid to eat away metal for visual texture and depth. Brushing imparts a satin sheen. Anodizing creates a scratch-resistant and colorfast outer layer on aluminum. Paint applications utilize specialized paints in spray guns or by hand for glossy vibrant hues or matte tones. Polishing brings out the natural luster of metals like brass and bronze. Carefully applied patinas result in a beautifully aged look.

Through banding, shaping, joining and finishing metal, craftspeople transform raw stock into enchanting decorative elements. These techniques enable architectural metal fabrication metalsmiths to design and hand-fabricate one-of-a-kind functional art that enhances any setting with both aesthetic beauty and structural integrity.

Sustainability in Metal Fabrication

Durable and Long-Lasting Materials

Marbles like the stainless and the aluminum are very hard materials that can last for decades and even centuries if well installed and little or no wear on it. Basically, since architectural metal fabrication means structures are more long-lasting they experience low levels of replacement hence bearing able impacts to the surrounding environment throughout its life cycle as compared to more temporal structures. Thoughtful material selection leads to sustainable building designs.

Recyclable Content

Steels, aluminum and other metals are easily recycled, many fabrication shops incorporate such recycled materials in their products. Designating structural elements in construction products which are partially or fully made from recycled feedstock enables the reduction of as landfill waste material and energy use… At end of life, metal elements can be recycled again, keeping material in continuous loop out of the waste stream.

Lean Manufacturing

Digital architectural metal fabrication techniques maximize efficiency. Computer numerical control facilitated by robotics and CAD/CAM modeling eliminate material waste by cutting only the precise shapes and dimensions required. Laser cutting leaves almost no scrap, and plasma cutting repurposes cutoff scrap for other applications. Lean production methodology systematically reduces waste throughout manufacturing process for optimal sustainability.

When leveraging the inherent durability of metal paired with sustainable practices in material sourcing and fabrication, the construction industry can greatly reduce environmental impact over time. An integrated approach considering the full lifecycle delivers long-lasting, recyclable building solutions.
