· Product Overview
This set of precision metal structural brackets includes four uniquely designed components — a black powder-coated long support bracket, a black U-shaped enclosure, a silver multi-hole mounting bracket, and a colorful zinc-plated L-shaped bracket. Engineered for high-load applications, these brackets combine robust construction with precise dimensions, serving as core structural elements for automotive, industrial, and electronic systems.
· Core Specifications
Dimensions(Customizable; Typical Specifications as Example)
- Black Long Support Bracket: Length 300mm × Width 50mm × Thickness 3mm (with 3× elongated mounting holes).
- Black U-Shaped Enclosure: Length 150mm × Width 100mm × Height 80mm (2× side mounting holes, internal partition).
- Silver Multi-Hole Bracket: Length 200mm × Width 150mm × Thickness 2.5mm (6× φ6mm mounting holes, 2× wiring cutouts).
- Colorful Zinc-Plated L-Bracket: Length 180mm × Width 120mm × Thickness 2mm (4× φ5mm mounting holes, curved edge).
Weight
- Black Long Bracket: ~500g
- Black U-Shaped Enclosure: ~300g
- Silver Multi-Hole Bracket: ~600g
- L-Bracket: ~400g
(Weight varies with material density: Cold-rolled steel ~7.85g/cm³, aluminum alloy ~2.7g/cm³, stainless steel ~7.93g/cm³).
Material
- Black Components: Cold-rolled steel (SPCC) + black powder coating (corrosion-resistant, wear-resistant).
- Silver Component: 6061-T6 aluminum alloy (lightweight, high strength-to-weight ratio).
- L-Bracket: Cold-rolled steel + colorful zinc plating (salt spray resistance ≥48 hours).
Process Standard
Compliant with ISO 9001 quality management system; dimensional accuracy ±0.1mm, surface roughness (Ra) ≤1.6μm, and meets IATF 16949 automotive-grade standards (for vehicle-mounted components).
· Application Scenarios
- Automotive Industry: Mounting brackets for EV battery packs, engine bay components, or suspension system supports.
- Industrial Equipment: Structural supports for conveyor systems, robotic arms, or machine tool enclosures.
- Electronics & Telecom: Racks for server cabinets, mounting frames for communication equipment, or heat sink brackets.
- Renewable Energy: Supports for solar panel mounting systems, wind turbine nacelle components, or energy storage system frames.
· Production Process Introduction
- Raw Material Selection: High-purity cold-rolled steel sheets (SPCC) or aluminum alloy plates (6061-T6) are selected for uniform mechanical properties.
- Precision Cutting:
- Laser Cutting: Shapes raw materials into blanks with ±0.05mm precision (ideal for complex cutouts like elongated holes or wiring notches).
- CNC Punching: Creates mounting holes and structural features (hole diameter accuracy ±0.1mm, hole spacing tolerance ±0.2mm).
- Bending & Forming:
- CNC press brakes form U-shaped, L-shaped, or multi-angle structures (bend radius ≥0.5× material thickness to avoid cracking).
- For reinforced brackets, ribs are pressed to enhance load-bearing capacity (rib height ≥3× thickness).
- Surface Treatment:
- Black Components: Electrostatic powder coating (film thickness 60–80μm, corrosion resistance ≥1000 hours salt spray).
- Silver Component: Anodizing (film thickness 10–15μm, Ra ≤0.8μm for smooth finish).
- L-Bracket: Zinc plating (thickness 8–12μm, salt spray resistance ≥48 hours).
- Quality Inspection:
- Dimensional inspection via CMM (coordinate measuring machine) to verify hole positions and bend angles.
- Load testing (static load ≥50kg for automotive brackets, ≥30kg for industrial brackets).
· Packaging and Shipping Methods
Packaging
- Inner Packaging: Each bracket is wrapped in anti-scratch film and placed in custom foam-lined trays to prevent deformation during transit.
- Outer Packaging: Sturdy cardboard boxes with “Heavy-Duty Metal Components – Handle With Care” labeling; for bulk orders, wooden crates with reinforced corners are used.
Shipping
- Logistics Options:
- Express: DHL/UPS/FedEx (3–7 business days for samples or small batches).
- Sea Freight: 20–30 days for bulk orders (economical for large quantities).
- Lead Time: 5–10 business days for standard orders, 15–20 days for custom designs.

· Frequently Asked Questions (FAQ)
Q1: Can I customize the dimensions, material, or surface finish?
A: Yes! We offer full OEM/ODM services. Provide 2D/3D drawings or sample specifications, and our engineering team will tailor the brackets to your exact requirements.
A: Yes! We offer full OEM/ODM services. Provide 2D/3D drawings or sample specifications, and our engineering team will tailor the brackets to your exact requirements.
Q2: How do I determine the load-bearing capacity of a bracket?
A: Load capacity depends on material (e.g., 6061-T6 aluminum supports ~30kg static load, cold-rolled steel supports ~80kg). Share your application’s weight and stress conditions, and we’ll recommend the optimal material and thickness.

Q3: Are these brackets suitable for outdoor use?
A: Yes. Powder-coated/cold-rolled steel brackets withstand outdoor conditions (humidity, UV) for 5–10 years; zinc-plated brackets offer salt spray resistance ≥48 hours (ideal for marine or coastal environments).

Q4: What installation methods are recommended?
A: Common methods include:
A: Common methods include:
- Screw Mounting: Use M4–M8 bolts (match hole size and material).
- Welding: Spot welding or arc welding (for permanent, high-load connections).
- Adhesive Bonding: Use industrial-grade structural glue (e.g., epoxy) for non-destructive installation.
Q5: What if a bracket arrives damaged or doesn’t meet specifications?
A: Each order includes a quality inspection report. If damage occurs during shipping or dimensional errors exist, contact us within 7 days for a free replacement or refund.
