In-House Metal Grinding & Metal Sanding Services
There are many forms of metal grinding and metal sanding, and GTR Manufacturing performs them all with precision and consistency. Sometimes referred to as “time-saving,” metal sanding is commonly used to remove burrs and surface imperfections from sheet metal after laser cutting, punching, or shearing. In other applications, sanding is used to modify the original grain structure of the material to help prevent cracking during forming, especially in parts with tight bends or complex geometries.
Sanding can also serve as a decorative finish and improves adhesion for plating and paint, ensuring a high-quality final appearance. Both wet and dry sanding processes are available at our manufacturing facility. Dry sanding is more time-efficient and removes more material, while wet sanding is ideal for customers who require a smoother, more refined finish.
In contrast, metal grinding is typically used to remove welds created during spot welding or welding, deburr edges, and refine part geometry after fabrication. Grinding can also be applied to achieve cosmetic finishes such as straight grain or orbital patterns. Together, grinding and sanding play a critical role in delivering clean, finished components that integrate seamlessly with downstream processes like hardware insertion and final assembly. Both techniques contribute to the production of great-looking, high-quality sheet metal parts.

Engineering & Design Support
GTR Manufacturing’s experienced engineering department can provide concepts, design changes, product enhancements, and reverse engineering. We will work with your team to deliver your parts at competitive costs.
Our sales, management, and engineering teams have experience in a wide range of industries and understand the changing needs of all of them. We work in close partnership with our clients in developing and refining product designs and production process planning to simplify manufacturing and create cost savings for your end product.
We have the capability to import and unfold your 3D models ( .dwg, .step, .iges, .sldasm, .ldprt, .dxf) built in Solid Works, Pro/E, and other modeling software. The model is unfolded and downloaded directly into the CAM process, reducing errors and assisting in short lead times for your sheet metal parts.
JIT / KANBAN
By using the Just-In-Time (JIT) inventory strategy, GTR Manufacturing schedules production to meet your ordering needs. We reduce costs by carrying less idle inventory, resulting in a quality product that is delivered on time at a lower price.
We pair JIT with the Kanban technique to manage our highly-efficient development process. We establish minimum and maximum quantities, fulfilling customer needs on a pull system. This method empowers us to reduce inventory for customers and suppliers and uses lean production practices. In addition, we have full insight into your pipeline through an online portal, ensuring it’s always full.
