Custom Metal Brackets, Built for Your Design.
BracketMFG is not a general sheet metal shop. We engineer and fabricate precision custom metal brackets for industrial and OEM applications. From single-part prototypes to high-volume stamping runs, manufactured directly at our Dongguan facility with rigorous DFM support.
Core Production Workflows:
Direct Engineering DFM Verification
Every STEP, DXF, and drawing is checked for bend radius limits, hole distortion clearance, and stack-up tolerances before manufacturing commences.
Dedicated Focus
Custom Brackets Are What We Do
Unlike generalized sheet metal job-shops that divide focus across housings, enclosures, and ductwork, BracketMFG specializes exclusively in metal brackets engineered for load-bearing, alignment, and precision retention.

Designed to Fit. Designed to Manufacture.
Bracket assembly issues rarely stem from catastrophic failures—they fail in assembly lines due to minor geometric incompatibilities: hole stretch on the bend line, hardware clash with press brake tooling, or plating buildup affecting tap clearance.

Quality Assurance
Consistency Matters More Than One Good Sample
Anyone can make one acceptable bracket sample by hand. What hardware engineers and procurement managers need is absolute repeatability across run sizes of 500, 5,000, or 50,000 units.
Because brackets serve as mechanical mounting points, a 0.5-degree variation in bend angle translates into noticeable displacement at the end of an assembly arm. We eliminate this through calibrated inspection regimes.
Raw Material Verification
Mill test certificates (MTC) archived per batch. Spectrometry confirmation of alloy grade, temper, and tensile standards.
First Article Inspection (FAI)
Comprehensive dimension check against 2D drawings using optical comparators and digital height gauges before mass runs.
In-Process Angle Tracking
Laser check of bend angles at scheduled intervals during press operations to compensate for coil springback variation.
Packaging & Edge Protection

Frequently Asked Questions
Direct answers to technical and commercial questions from engineers and procurement teams.
What types of custom metal brackets can you produce?
We manufacture L, U, and Z brackets, structural gusset brackets, cantilever supports, camera/sensor mounts, electronics chassis brackets, and multi-component welded OEM assemblies.
What is your minimum order quantity (MOQ)?
Our MOQ is 1 piece for prototypes and pilot design verification. We utilize CNC laser cutting and press brake forming to eliminate hard tooling costs on low-volume runs.
What CAD file formats do you accept for quotation?
We recommend 3D native files in STEP (.step, .stp) or IGES format, paired with a 2D PDF drawing calling out critical tolerances, threads, finish specifications, and hardware part numbers.
What dimensional tolerances can you hold on formed brackets?
Our standard sheet metal cutting and forming tolerance is ±0.10 mm (ISO 2768-m) and ±0.5° on bend angles. Secondary CNC machining or precision progressive dies can hold critical features to ±0.05 mm.
Can you install PEM fasteners, studs, and standoffs?
Yes. We have dedicated Haeger insertion equipment with automatic feed systems for genuine PEM nuts, studs, and standoffs in standard metric (M2–M10) and imperial (#2 to 3/8") threads.
When should we switch from laser cutting to stamping dies?
The economic break-even point typically occurs between 2,500 and 5,000 units, depending on the bracket's size and feature complexity. We evaluate tool amortization versus per-unit laser cycle costs to advise you.
Do you ship custom metal brackets to the United States?
Yes. Over 70% of our production volume ships to customers across the United States. We manage express air freight (3–5 business days) for prototypes and sea freight (DDP/FOB) for mass production containers.
Can your engineers assist with Design for Manufacturability (DFM)?
Yes. Every drawing is reviewed for bend relief, minimum flange length, hole distortion zones, and tool clearances. If an optimization will reduce unit cost or scrap rate, we provide actionable recommendations.
