Custom Sheet Metal Fabrication
Precision Welding & Grinding Services for Custom Sheet Metal
At Rapidsheetfab, we understand that high-quality welded assemblies are critical to the performance and appearance of your equipment. As an ISO 9001:2015 certified custom sheet metal manufacturer, we provide industrial OEMs with reliable, multi-process welding and post-weld grinding services.
Whether you need a single prototype enclosure for an NPI build or low-volume repeat production of complex structural frames, our skilled technicians and strict quality controls ensure your parts meet both dimensional and cosmetic requirements.
Our Welding Capabilities
We offer a comprehensive range of in-house welding technologies to suit different materials, structural requirements, and cosmetic standards:
TIG Welding (GTAW)
Ideal for highly precise, clean, and aesthetically critical joints. Commonly used for stainless steel and aluminum enclosures in medical, laboratory, and electronics applications.
MIG/MAG Welding (GMAW)
Provides strong, efficient, and deep-penetrating welds. Perfect for heavy structural frames, carbon steel bases, and machinery components.
Laser Welding
Delivers concentrated heat with minimal thermal distortion. Excellent for thin-gauge sheet metal, complex geometries, and achieving seamless cosmetic finishes.
Spot Welding
A fast, cost-effective solution for joining overlapping sheet metal panels, brackets, and internal chassis components without adding weight or filler material.
Post-Weld Grinding & Surface Preparation
Inconsistent cosmetic quality is a common pain point in sheet metal fabrication. Rapidsheetfab eliminates this by offering meticulous in-house post-weld processing:
- Weld Leveling & Grinding: Smoothing out weld seams to create seamless, flush surfaces before painting or plating.
- Deburring & Edge Rounding: Removing sharp edges and spatter to ensure safe handling and precise assembly.
- Brushing & Graining: Applying directional grain finishes (e.g., to SUS304/SUS316) for premium, ready-to-use stainless steel panels.
- Basic Polishing: Preparing surfaces for final partner-managed finishing processes like powder coating, anodizing, or plating.
Materials We Weld & Grind
Our welding and grinding processes are optimized for a wide range of standard sheet metal materials (typically 0.5–12 mm thickness):
Stainless Steel
SUS304, SUS316, and SUS430
Carbon Steel
SPCC/CRS, Q235/Q355, and SGCC/SECC
Aluminum
5052, 6061, and 5754
Note: We also process Copper C1100/T2 and Brass H62 depending on project requirements.
Why Choose Rapidsheetfab for Welded Assemblies?
We are not just a commodity cutting shop; we are an engineering-responsive manufacturing partner built for industrial OEMs.
One-Stop Assembly
Stop managing multiple suppliers for a single assembly. We handle laser cutting, CNC bending, hardware insertion (PEM/tapping), welding, grinding, and final assembly under one roof.
Prototype to Production Continuity
We support an MOQ of 1 piece. We validate your design during the prototype phase (3–12 days) and scale seamlessly into regular production (15–25 days).
Engineering & DFM Support
We provide fast, clear Design for Manufacturing (DFM) feedback to help you optimize weld joints, avoid thermal distortion, and reduce manufacturing costs.
Export-Ready Communication
Since 2019, we have served clients in the US, Canada, EU, and Australia. Our team understands your standards and communicates responsively in English.
Stringent Quality Control & Documentation
Welded assemblies require rigorous inspection to ensure they meet your exact tolerances and specifications. Our ISO 9001:2015 certified quality flow (IQC, FAI, IPQC, FQC, OQC) guarantees consistency.
Inspection Resources & Deliverables
- CMM and 2.5D Vision Systems for checking critical dimensions post-welding.
- First Article Inspection (FAI) reports for NPI builds.
- Detailed dimensional reports and material certificates.
- RoHS/REACH documentation and coating reports (via our qualified finishing partners).
Typical Applications
Our welding and grinding services are trusted by automation, robotics, energy, and machinery manufacturers for:
- Custom electrical enclosures and control cabinets
- Welded structural frames and machine bases
- Internal electronics chassis and power supply housings
- Medical and laboratory equipment panels
- Heavy-duty brackets and mounting hardware
