Send prints, specs, and timeline.
We review details, then confirm materials, fit, and approach.
We build, check, and deliver, then support installation needs as required.
From concept to completion, GSM Industrial provides the engineering, design, and metal fabrication support needed to bring complex industrial projects to life. Whether you’re starting with a detailed drawing, replacing obsolete equipment, or developing a new idea, our team works closely with you to deliver solutions that meet your specifications and project goals.
Our capabilities include:
Quality fabrication starts with quality welding. Our certified welders are regularly tested and re-certified to meet stringent industry standards, ensuring every project is completed with precision, consistency, and long-term reliability.
Our welding capabilities include:
GSM fabricates components and assemblies using a wide range of materials selected for each project’s performance requirements.

Many of our employees have spent decades perfecting their craft, giving customers the confidence that their projects are being completed by an experienced team that understands demanding industrial applications.
From build-to-print metal fabrication to large industrial assemblies, GSM has the equipment, engineering expertise, and production capacity to support projects of varying sizes and complexity.
Every project is fabricated to your specifications and supported by rigorous quality control processes to help ensure components are built right the first time.
Need more than industrial fabrication? GSM can support projects from design through fabrication and field installation, providing a single partner throughout the project lifecycle.
Our fabrication facility and equipment allow us to take on projects ranging from custom components to large industrial assemblies.
Whether you need a single custom-fabricated component, a complex industrial assembly, or a turnkey solution from design through installation, GSM Industrial has the expertise to bring your project to life. Our team will work with you to understand your requirements, provide practical recommendations, and deliver metal fabrication services built to perform.
With locations in Lancaster and Annville PA, GSM Industrial provides custom metal fabrication for customers throughout the East Coast and across the United States.
The more information you can provide, the more accurately we can scope your project. Customer drawings, dimensions, material specifications, quantities, photos, existing components, and project timelines all help us develop an accurate quote.
If you don’t have complete documentation, our team can work with you to determine the best path forward.
Whenever possible, it’s beneficial to involve your fabrication partner early in the planning process. Early collaboration allows us to provide input on manufacturability, material selection, project scheduling, and potential cost-saving opportunities before fabrication begins.
We support projects of all sizes. GSM Industrial fabricates one-of-a-kind custom equipment as well as recurring production components and larger fabrication programs, depending on your project’s needs.
Yes. If replacement equipment is no longer available, GSM Industrial can often fabricate a custom replacement using existing drawings, field measurements, or reverse-engineered components. Our team works with customers to restore or improve equipment performance while meeting current operational requirements.
We can support laser cutting when your design calls for it, and we regularly complete sheet metal jobs through our sheet metal shop capabilities. If you need repeatable parts, clean edges, and a consistent fit, we will quote the best path based on your drawings.
GSM works with customers to understand the quality, documentation, certification, and specification requirements associated with their projects. Our team can coordinate fabrication and quality processes around project-specific requirements and applicable industry standards.
