QUALITY. LOYALTY. INTEGRITY.

Our Services

Our services at Kaempf & Harris focus on precision sheet metal fabrication for commercial and industrial applications. From custom ductwork to complex architectural components, we deliver expertly crafted solutions built to perform.

Sheet Metal Fabrication

This is the heart of what we do! The process of sheet metal fabrication is about more than just cutting and welding. A lot of work and preparation goes into a project before the fabrication itself even begins. High-quality materials aluminum, steel, copper, and stainless steel are a priority for us, as they allow us to provide the best possible product for our clients. Once the materials have been selected, they undergo cutting, bending, and shaping with the utmost care and precision. These processes are made possible with high-tech equipment including CNC lasers, press brakes, and turret punches. Welding, riveting, and fastening are all performed by trained professionals to assemble all the components into the final product.

We can handle sheet metal projects of any scale. Just take a look at the scope of Frederick’s Rose Hill Cancer Center, for which we provided over 75,000 pounds of sheet metal and much more!

Design-build Services

Kaempf & Harris has been a leader in design-build services, offering a streamlined approach to project delivery. By integrating design and construction, we ensure that projects are completed on time and within budget, while maintaining the highest standards of quality and innovation.

Metal Fabrication Services

Our additional metal fabrication services focus on the precise creation of more complex products. Sheet metal focuses on thin, flat pieces of metal, whereas these services offer solutions for a broader range of metal types. Whether you need custom brackets, frames, or other structural components, you’ll find the expertise your project requires here. Once the fabrication itself is complete, take advantage of the finishing expertise offered by our team painting, powder coating, and galvanizing. This ensures your final completed product exceeds not just your functional requirements, but your aesthetic expectations!

Sheet Metal Installation

Kaempf & Harris specializes in delivering precise sheet metal installation services tailored to meet the unique demands of each project. Our team is equipped with the skills and experience necessary to handle complex installations, ensuring that every component is fitted with accuracy and care.
