Frequently Asked Questions

Sheet Metal Manufacturing

F.A.Q.

Our favorite question is, “How can we help?” Below, we have answered some of the most common inquiries that we receive, but if you are looking for information not provided here, please get in touch, and someone from our crew will respond ASAP.

How fast can I get a quote?

Once we receive your files, a quote will be submitted back to you within 24 hours. Standard fabrication lead time on flat panels without finish is 5 business days or less and on non-complex geometric parts without finish is 7-10 business days. Standard finishes add approximately 3-5 days depending on type of finish. Our lead time clock starts ticking 24 hours after receipt of order and is calculated as business days (5 days a week, not including weekends). The number of days given represents our ship date and not dock date.

What files can you receive?

We can quote from STEP, SLDPRT, DXF and Native PDF files. We will manufacture from model files.

Does GTR offer in-house finishing and coating?
Yes. We operate a dedicated on-site finishing department so your parts can move directly from fabrication to finishing without leaving our facilities. Our in-house capabilities include painting, powder coating, chem film, and silk screening, along with related prep and inspection. Keeping finishing under one roof gives you tighter quality control, fewer handoffs, and shorter overall lead times as part of our single-source manufacturing solution.
What materials can GTR work with for sheet metal fabrication?
We work with a wide range of commonly specified sheet metal materials, including aluminum, stainless steel, cold rolled steel, galvanized steel, and specialty alloys. Material availability and suitability depend on part requirements such as strength, corrosion resistance, finish, and end use. If you do not see your material listed here, please contact us and let us know what material you are looking for.
What tolerances can GTR hold on sheet metal parts?
Tolerances vary based on material type, thickness, part geometry, and overall complexity. We routinely hold tight, repeatable tolerances suitable for precision assemblies, enclosures, and electromechanical components. For applications with critical tolerance requirements, our team will review your prints up front to confirm expectations before production begins.
How do my parts get shipped?

We will gladly process shipments under your preferred logistic organization using your account number or we will provide PrePay and Ship using our UPS account.

Do you offer welding?

Yes, we have TIG welding capabilities along with spot welding.

What kind of finishes do you offer?

Powder coat, paint, silk-screening, chromate (clear RoHS and yellow), zinc plating, anodize (clear/ black), passivate, and electro-polish.

What are your payment terms?

We offer highly-secured, 3rd party credit card payments. Net 30 terms can be offered to existing customers or with new customers pending credit approval.

What’s the largest sheet metal part GTR can form?
Our forming equipment is set up to handle everything from small brackets to large chassis, cabinets, and enclosure panels. Because maximum size depends on material, thickness, and bend geometry, the best way to confirm fit is to send us your print or 3D model. Our engineering team will review your design and quickly let you know whether it’s within our forming window or recommend minor adjustments to make it manufacturable.
How fast can GTR turn around a prototype order?
Speed is a core part of our rapid prototyping offering. Once we receive your files, we typically return a quote within 24 hours. Standard fabrication lead times for most prototype parts without finishing are measured in business days, not weeks, and standard finishes add only a few additional days. If you are working toward a specific launch date, let us know your target and we will align our schedule accordingly or suggest options to accelerate your timeline.
Can GTR support both one-off prototypes and production runs?
Yes. Our sheet metal operation is designed to scale with your needs. We regularly support one-off and low-volume prototypes during early design phases and seamlessly transition those parts into repeat or higher-volume production once designs are finalized. This continuity helps eliminate rework, maintain consistency, and accelerate time to market.
What makes GTR’s rapid sheet metal prototyping different?
Our rapid sheet metal process combines fast quoting, dedicated prototyping capacity, and in-house fabrication and finishing. But what makes us different is the Design for Manufacturability (DFM) we offer. If you have any questions or concerns with your project, our engineers will work with you and find the best way to manufacture your part so that no problems occur during fabrication.

We provide innovators with the highest quality precision sheet metal Fabrication and do so at a level of speed, craftsmanship, and service that exceeds all standards and expectations.
