The Most Overlooked, Most Essential Component
Walk through any factory, any piece of heavy equipment, any building – and you will see them. Brackets. Hundreds of them. L‑shaped, Z‑shaped, U‑shaped, triangular, custom punched, welded, or bent. They hold up conveyor systems, mount medical devices, brace solar panels, and secure electronics inside enclosures.
For fabricators and OEMs, brackets represent a constant challenge:
Endless variety – each project needs a different shape, hole pattern, or thickness.
Low margins – customers expect cheap, simple parts, but traditional cutting methods eat into profit.
High mix, low volume – you might need 50 pieces of 10 different designs. Tooling up for each is impossible.
Yihai’s fiber laser cutting machines turn this problem on its head. With no tooling cost, instant design changes, and the ability to cut any shape from any material, our laser makes bracket fabrication fast, flexible, and profitable – whether you need 5 pieces or 5,000.
The Bracket Types You Can Cut – And Our Advice for Each
L‑Bracket (Angle Bracket)
Common Sizes / Thickness: 40x40mm to 200x200mm, 2‑6mm thick Critical Features: Sharp inside corner, precise hole locations
Gusset / Triangular Bracket
Common Sizes / Thickness: 50‑300mm legs, 3‑8mm thick Critical Features: Consistent edge for welding, accurate hole pattern
Z‑Bracket (Offset Bracket)
Common Sizes / Thickness: Width 20‑80mm, thickness 2‑5mm Critical Features: Parallel flanges, consistent offset
U‑Bracket (Channel Bracket)
Common Sizes / Thickness: 50‑200mm wide, 2‑6mm thick Critical Features: Flat bottom, square corners
T‑Bracket
Common Sizes / Thickness: Various, often 3‑8mm thick Critical Features: Symmetrical shape, accurate centerline
Custom / Architectural Bracket
Common Sizes / Thickness: Any shape, often decorative Critical Features: Smooth curves, consistent edge for finishing
Quality Matters – Especially When Brackets Are Safety‑Critical
Dimensional accuracy
What It Means: Holes align, brackets fit the first time
Yihai’s Standard:±0.02mm/m positioning, ±0.01mm repeatability
Burr height
What It Means: No sharp edges, ready to handle
Yihai’s Standard: <0.05mm with N₂ cutting
Heat‑affected zone (HAZ)
What It Means: No micro‑cracks, no weakened material
Yihai’s Standard: <0.3mm – minimal, preserves strength
Edge perpendicularity
What It Means: No taper, brackets sit flat
Yihai’s Standard: <0.05mm over 10mm thickness
Surface condition
What It Means: No oxide, ready for welding or coating
Yihai’s Standard:Oxide‑free with N₂ assist
High mix / low volume
What It Means: (custom enclosures, prototypes)
Yihai’s Standard: No hard tooling. Switch between jobs in minutes.

With Yihai laser cutting:
Customer sends drawing (1 hour)
Shop loads CAD into nesting software (15 minutes)
Laser cuts first bracket (1‑2 minutes)
Test fit, adjust CAD if needed (30 minutes)
Production run (hours)
Total time to first bracket: <2 hours
1.CAD Design
You receive a customer’s 3D model or drawing.
2. Nesting & Programming
Our software nests parts efficiently, reducing material waste by up to 20%.
3. Laser Cutting
Yihai machine cuts all flat patterns (top, bottom, sides, brackets, vents, mounting holes).
4.Deburring (Often Skipped)
Clean cut edges mean minimal or no deburring.
5. Bending & Forming
Precise cutouts ensure accurate bend lines and flange alignment.
6. Welding & Assembly
Tight fitting parts mean less gap filling and stronger welds.
7. Surface Finishing
Smooth cut edges accept powder coating, anodizing, or plating uniformly.
8. Packaging & Shipment
Consistent parts mean reliable assembly every time.
Thickness & Power Guide – Matching Your Laser to the Job
| Bracket Thickness | Recommended Laser Power | Expected Speed (m/min) | Edge Quality |
|---|---|---|---|
| 1‑2 mm (light duty) | 1‑2 kW | 8‑15 | Excellent – burr‑free |
| 3‑4 mm (medium duty) | 2‑4 kW | 4‑8 | Very good – minimal burr |
| 5‑6 mm (heavy duty) | 4‑6 kW | 2‑4 | Good – slight dross easily removed |
| 8‑10 mm (extreme duty) | 6‑12 kW | 1‑2 | Acceptable – may need light grinding |

Materials for Brackets – Cut Them All on One Machine
| Material | Why Used for Brackets | Laser Cutting Performance |
|---|---|---|
| Mild steel (A36, 1008, etc.) | General purpose, strong, cheap, weldable | Excellent – fast, clean, lowest cost (use O₂ or N₂) |
| Stainless steel (304, 316) | Corrosion resistance (outdoor, medical, marine) | Very good – use N₂ for clean, burr‑free edge |
| Aluminum (5052, 6061) | Lightweight (aerospace, electronics, portable equipment) | Good – requires anti‑reflective protection (standard) |
| Galvanized / Galvanneal | Outdoor electrical, HVAC, solar mounting | Excellent – zinc coating stays intact with N₂ |
| Brass / Copper | Decorative, EMI shielding, conductive brackets | Specialized – pulse mode + anti‑reflection (available) |
